Excel leveraging medians

To calculate median values in a PivotTable in Excel, you need to use a workaround because PivotTables do not have a built-in function for the median (unlike average, sum, etc.). Here’s how you can calculate median values step by step:

Method 1: Using Helper Columns

1. Add a Helper Column:

• In your dataset, add a helper column for ranking or grouping data. For example, add a column that uniquely identifies records for each group (e.g., dates, categories, or regions).

2. Sort the Data:

• Sort your data by the field for which you want to calculate the median.

3. Use the MEDIAN Function:

• Outside the PivotTable, use the MEDIAN function for each group.

• Example:

• If your group is “Category A” and your values are in Column D, use:

=MEDIAN(IF(A:A="Category A", D:D))

• Use Ctrl + Shift + Enter for array formulas (or just Enter in newer versions of Excel).

Method 2: Using Power Query (Preferred for Large Data)

1. Load Data into Power Query:

• Select your dataset → Go to the Data tab → Click Get & Transform Data → Choose From Table/Range.

2. Group the Data:

• In Power Query, use the Group By feature.

• Select the column to group by (e.g., “Category”).

• Under Operations, choose All Rows.

3. Add a Median Column:

• For each group, add a custom column to calculate the median.

• Use the formula:

=List.Median([Values])

4. Load Back to Excel:

• Once done, load the grouped table back into Excel.

Method 3: Using DAX in a Data Model

1. Load Data to Power Pivot:

• Select your data → Go to the Insert tab → Click PivotTable → Check Add this data to the Data Model.

2. Create a DAX Measure:

• In the Power Pivot window, create a new measure:

MedianValue = MEDIAN(Table[ValueColumn])

3. Add Measure to PivotTable:

• Add the DAX measure to your PivotTable to calculate the median dynamically.

These methods will allow you to calculate medians and display them effectively in your PivotTables. For large datasets, Power Query or DAX is more efficient.

Oracle CLOB to BigQuery

To transfer a CLOB (Character Large Object) from Oracle to BigQuery, follow these steps:

1. Extract CLOB Data from Oracle

You need to extract the CLOB data in manageable chunks, as shown in the error message, because the CLOB data size exceeds the buffer limit. Use one of the following methods:

Option A: Using DBMS_LOB.SUBSTR

SELECT DBMS_LOB.SUBSTR(wo_task_card_xml, 4000, 1) AS clob_chunk

FROM odb.wo_task_card

WHERE wo_task_card_xml IS NOT NULL;

This extracts the first 4000 characters of the CLOB. Repeat the process for the remaining chunks by adjusting the starting position.

Option B: Export the Entire CLOB

Use Oracle SQL Developer or a similar tool to export the full CLOB content into a text or CSV file.

2. Save the Extracted Data

• Save the CLOB data into a file in a readable format (e.g., .csv, .json).

• Ensure the file adheres to BigQuery’s schema requirements.

3. Prepare BigQuery Schema

BigQuery does not support CLOBs directly. Instead, store the CLOB as a STRING or JSON in BigQuery. Define a column with a STRING type in your BigQuery table.

4. Load Data into BigQuery

Use one of these methods to load data:

Option A: BigQuery Console

1. Upload the exported file via the BigQuery web interface.

2. Map the CLOB field to the STRING column.

Option B: BigQuery CLI

Use the bq command-line tool:

bq load --source_format=CSV your_dataset.your_table path_to_file.csv schema.json

Option C: Dataflow/ETL Tools

Use tools like Google Dataflow, Apache Beam, or Fivetran for automated CLOB extraction and transfer.

Additional Notes

• Ensure that your CLOB data is UTF-8 encoded to avoid character encoding issues.

• If the CLOB contains XML/JSON, validate it before loading into BigQuery.

Organization transition from SCCM to Microsoft store

Organizations can switch from System Center Configuration Manager (SCCM) to leverage the Microsoft Store for Business or Microsoft Store in Intune as part of a modern software distribution and management strategy. However, the feasibility and effectiveness of this switch depend on the organization’s needs and the features available in these platforms.

Key Considerations for Switching

1. Benefits of Using the Microsoft Store for Business

• Centralized Management:

• Organizations can use the Microsoft Store for Business to acquire, manage, and distribute apps to users.

• Integration with tools like Microsoft Intune enables seamless app deployment and updates.

• Seamless Updates:

• Apps from the Microsoft Store update automatically, reducing the need for manual patching or deployments.

• Simplified Deployment:

• Pre-packaged apps in the Microsoft Store are ready for deployment without additional packaging efforts required in SCCM.

• Cost Efficiency:

• Reduces reliance on SCCM infrastructure, which can save on server costs and administrative overhead.

• User Self-Service:

• Users can access approved apps directly through a company-managed store, improving productivity.

2. Limitations of the Microsoft Store

• Limited Software Availability:

• Not all enterprise applications are available in the Microsoft Store. Many enterprise apps require custom installers, which SCCM handles effectively.

• Custom Installations:

• SCCM supports customized installations (e.g., silent installs, pre-configuration settings), which are harder to achieve through the Microsoft Store.

• Compliance and Security:

• SCCM offers granular control over deployments, configurations, and compliance policies that may be more robust than what the Microsoft Store provides.

• Legacy and Non-UWP Apps:

• The Microsoft Store primarily supports Universal Windows Platform (UWP) apps. Legacy apps and apps requiring deep system integration may not be available.

3. Use of Microsoft Intune as a Bridge

Organizations moving away from SCCM can combine Microsoft Intune with the Microsoft Store for Business:

• App Deployment:

• Intune can deploy apps from both the Microsoft Store and external sources, providing flexibility for software not available in the Store.

• Device Management:

• Intune provides mobile device and PC management capabilities, replacing SCCM’s device management features.

• Policy Enforcement:

• Intune allows enforcement of security and compliance policies.

4. Hybrid Approach

For organizations with diverse requirements, a hybrid approach can be effective:

• Use SCCM for managing legacy, custom, or complex applications.

• Use the Microsoft Store (via Intune) for modern UWP apps and straightforward installations.

• Gradually transition workloads to Intune as more apps adopt modern packaging.

5. Key Scenarios for Switching

• Small to Medium Businesses (SMBs):

• The Microsoft Store for Business with Intune is a cost-effective solution for SMBs with simpler IT needs.

• Cloud-First Organizations:

• Organizations moving to a fully cloud-based infrastructure may benefit from Intune and the Store for app management.

• Modern Device Deployment (Windows Autopilot):

• The Microsoft Store integrates well with Windows Autopilot for zero-touch device provisioning.

6. Considerations for Transition

• Training:

• IT teams need training on Intune and Microsoft Store management.

• Software Compatibility:

• Evaluate if all required software is available or can be transitioned to modern app packages.

• Cost Analysis:

• Assess costs associated with migrating to Intune and decommissioning SCCM infrastructure.

Conclusion

Switching from SCCM to the Microsoft Store and Intune is feasible for many organizations, especially those prioritizing cloud-based infrastructure and modern app delivery. However, for enterprises with complex app requirements or reliance on legacy systems, SCCM may still be necessary in a hybrid setup.

Would you like guidance on implementing a specific transition strategy or exploring Intune in more detail?

Tableau journey to join windows store

Tableau Desktop is not available in the Windows Store due to several key reasons related to the way Tableau is designed, distributed, and managed:

1. Software Complexity

• Tableau Desktop is a robust data visualization tool that relies on specific configurations, custom installers, and libraries that may not be compatible with the Microsoft Store’s app packaging standards.

• Microsoft Store apps often use the Universal Windows Platform (UWP) framework, which imposes certain restrictions that Tableau Desktop doesn’t conform to.

2. Licensing and Pricing Model

• Tableau uses a subscription-based licensing model (e.g., Tableau Creator), requiring license activation via Tableau’s account system. This model may not align with the transactional framework of the Microsoft Store.

• Licensing often involves enterprise agreements or volume licensing, which is managed directly through Tableau’s website or authorized resellers.

3. Enterprise-Level Features

• Tableau Desktop is an enterprise-grade software that integrates with complex systems like databases, APIs, Tableau Server, and Tableau Cloud.

• It is typically deployed in corporate environments where IT teams manage installations and configurations. These enterprise deployment scenarios are better handled outside the Microsoft Store’s consumer-oriented model.

4. Platform Independence

• Tableau Desktop supports both Windows and macOS. By hosting its downloads on its website, Tableau ensures platform-agnostic distribution.

• The Windows Store is primarily designed for UWP apps, whereas Tableau Desktop requires platform-specific installers with dependencies.

5. Security and IT Management

• Enterprises often require greater control over how software is installed and managed (e.g., silent installations, IT-managed updates). Direct downloads from Tableau’s site allow IT administrators to use tools like:

• Microsoft Intune

• SCCM (System Center Configuration Manager)

6. Legacy Systems Compatibility

• Tableau Desktop supports older versions of Windows (e.g., Windows 10 and earlier). The Microsoft Store often targets more modern systems, potentially leaving legacy users without access.

7. Application Size and Customization

• Tableau Desktop is a heavyweight application that includes drivers, connectors, and libraries for integration with databases and other tools.

• Packaging such a feature-rich application to meet Microsoft Store requirements may compromise functionality or require significant development effort.

8. Focus on Direct Relationships

• Tableau prioritizes a direct relationship with its users and enterprises through its own website for support, updates, and licensing.

• This allows them to maintain greater control over customer experience and avoid reliance on third-party platforms like the Windows Store.

Alternatives in the Microsoft Store

While Tableau Desktop is not available, alternatives like Tableau Public (a free version with limited functionality) can be used by casual users. However, this is also distributed directly from Tableau’s website, not via the Windows Store.

If you have specific needs for Tableau, such as enterprise deployment or app store-like access, Tableau may be deployed using alternative methods, such as managed app deployment through Microsoft Intune or VDI solutions. Let me know if you’d like more details!

Row based batch processing

To efficiently process large datasets from Oracle into Python DataFrames while avoiding the ORA-02399: exceeded maximum connect time error, you can break down query size in multiple ways. Below are several approaches:

1. Row-Based Batch Processing

Retrieve data in chunks using ROWNUM or OFFSET/FETCH.

import cx_Oracle

import pandas as pd

def fetch_data_in_batches(connection, query, batch_size):

  offset = 0

  data_frames = []

  while True:

    batch_query = f"""

    SELECT * FROM (

      SELECT a.*, ROWNUM rnum

      FROM ({query}) a

      WHERE ROWNUM <= {offset + batch_size}

    )

    WHERE rnum > {offset}

    """

    cursor = connection.cursor()

    cursor.execute(batch_query)

    rows = cursor.fetchall()

    if not rows:

      break

    columns = [col[0] for col in cursor.description]

    df = pd.DataFrame(rows, columns=columns)

    data_frames.append(df)

    offset += batch_size

  return pd.concat(data_frames, ignore_index=True)

# Example usage

dsn = cx_Oracle.makedsn("hostname", "port", service_name="service_name")

connection = cx_Oracle.connect(user="username", password="password", dsn=dsn)

query = "SELECT * FROM your_table"

batch_size = 1000

final_df = fetch_data_in_batches(connection, query, batch_size)

connection.close()

Advantages:

• Works well for tables with ordered rows.

• Limits memory usage during query execution.

2. Time-Based Partitioning

Split the query using a time range or date column for large datasets with timestamps.

def fetch_data_by_date_range(connection, table, start_date, end_date, interval_days):

  current_date = start_date

  data_frames = []

  while current_date < end_date:

    next_date = current_date + pd.Timedelta(days=interval_days)

    query = f"""

    SELECT * FROM {table}

    WHERE date_column >= TO_DATE('{current_date.strftime('%Y-%m-%d')}', 'YYYY-MM-DD')

     AND date_column < TO_DATE('{next_date.strftime('%Y-%m-%d')}', 'YYYY-MM-DD')

    """

    cursor = connection.cursor()

    cursor.execute(query)

    rows = cursor.fetchall()

    if rows:

      columns = [col[0] for col in cursor.description]

      df = pd.DataFrame(rows, columns=columns)

      data_frames.append(df)

    current_date = next_date

  return pd.concat(data_frames, ignore_index=True)

# Example usage

import datetime

start_date = datetime.date(2023, 1, 1)

end_date = datetime.date(2023, 12, 31)

final_df = fetch_data_by_date_range(connection, "your_table", start_date, end_date, 30)

Advantages:

• Suitable for time-series data.

• Easily parallelizable if multiple workers query different ranges.

3. Key-Based Partitioning

Use primary key or indexed column ranges for splitting.

def fetch_data_by_key_ranges(connection, table, key_column, min_key, max_key, step):

  data_frames = []

  current_key = min_key

  while current_key < max_key:

    next_key = current_key + step

    query = f"""

    SELECT * FROM {table}

    WHERE {key_column} >= {current_key} AND {key_column} < {next_key}

    """

    cursor = connection.cursor()

    cursor.execute(query)

    rows = cursor.fetchall()

    if rows:

      columns = [col[0] for col in cursor.description]

      df = pd.DataFrame(rows, columns=columns)

      data_frames.append(df)

    current_key = next_key

  return pd.concat(data_frames, ignore_index=True)

# Example usage

final_df = fetch_data_by_key_ranges(connection, "your_table", "id", 1, 100000, 1000)

Advantages:

• Effective for evenly distributed numeric keys.

• Can process non-time-series data efficiently.

4. Query with Pagination (OFFSET/FETCH)

Use Oracle’s OFFSET and FETCH for pagination if supported.

def fetch_data_with_pagination(connection, query, batch_size):

  offset = 0

  data_frames = []

  while True:

    paginated_query = f"""

    {query}

    OFFSET {offset} ROWS FETCH NEXT {batch_size} ROWS ONLY

    """

    cursor = connection.cursor()

    cursor.execute(paginated_query)

    rows = cursor.fetchall()

    if not rows:

      break

    columns = [col[0] for col in cursor.description]

    df = pd.DataFrame(rows, columns=columns)

    data_frames.append(df)

    offset += batch_size

  return pd.concat(data_frames, ignore_index=True)

# Example usage

query = "SELECT * FROM your_table"

final_df = fetch_data_with_pagination(connection, query, 1000)

Advantages:

• Straightforward and modern approach.

• Supported in Oracle 12c+.

5. Partitioned Queries with Oracle Features

Use Oracle’s built-in partitioning or virtual column capabilities.

• If the table is partitioned, query each partition individually:

SELECT * FROM your_table PARTITION (partition_name);

• If using virtual columns, filter based on calculated values:

SELECT * FROM your_table WHERE virtual_column = some_value;

In Python, loop over the partitions or virtual column ranges dynamically.

6. Use Database Views or Materialized Views

Create a materialized view or database-side partition to simplify Python-side processing:

CREATE MATERIALIZED VIEW mv_table_partition AS

SELECT * FROM your_table WHERE MOD(id, 10) = 0;

Query each view in smaller chunks in Python.

7. Dynamic SQL for Custom Query Generation

Use Python to generate dynamic SQL queries to split the dataset into manageable chunks, processing each query iteratively.

Summary of Methods

Method Best For Complexity

Row-Based Batches Generic datasets Easy

Time-Based Partitioning Time-series data Moderate

Key-Based Partitioning Indexed or numeric columns Moderate

Pagination (OFFSET/FETCH) Supported Oracle versions Easy

Oracle Partitioning Large partitioned tables Advanced

Materialized Views Repeated queries Advanced

By selecting the appropriate method based on your dataset and requirements, you can avoid connection timeouts and process large datasets efficiently.

Batch Processing

The ORA-02399: exceeded maximum connect time, you are being logged off error in Oracle indicates that a session was forcibly terminated because it exceeded the maximum allowed connection time. This is often caused by long-running queries that take too much time to execute or retrieve results.

To avoid this error when executing queries in Python with Oracle, you can break down large queries or optimize the execution process. Here are the steps to achieve that:

1. Optimize the Query

• Add Filters: Reduce the result set by filtering unnecessary rows using WHERE conditions.

• Limit Rows: Use ROWNUM or FETCH FIRST N ROWS ONLY to limit the number of rows returned.

SELECT * 

FROM my_table

WHERE some_condition

FETCH FIRST 1000 ROWS ONLY;

• Use Indexes: Ensure the query uses appropriate indexes to speed up data retrieval.

• Avoid Large Joins: If the query involves multiple joins, consider splitting it into smaller queries or materialized views.

2. Break Down the Query

• Split large queries into smaller chunks based on a logical key (e.g., time ranges, primary keys, or batch processing). Here’s how you can do this:

Example: Fetching Data in Batches

Instead of retrieving all rows in one query, break it into smaller chunks using a key column, such as ROWNUM, ID, or DATE.

import cx_Oracle

# Connect to the Oracle database

connection = cx_Oracle.connect("username", "password", "hostname/service_name")

cursor = connection.cursor()

# Define batch size

batch_size = 1000

start_row = 1

while True:

  # Execute query with row limit

  query = f"""

    SELECT *

    FROM (

      SELECT ROWNUM AS rnum, a.*

      FROM my_table a

      WHERE ROWNUM <= {start_row + batch_size - 1}

    )

    WHERE rnum >= {start_row}

  """

  cursor.execute(query)

  # Fetch data

  rows = cursor.fetchall()

  if not rows:

    break # Exit loop when no more rows

  # Process the rows

  for row in rows:

    print(row) # Replace with your processing logic

  # Increment batch

  start_row += batch_size

cursor.close()

connection.close()

3. Use Pagination

If the query returns a large number of results, implement pagination by using a combination of OFFSET and FETCH clauses:

page_size = 1000

offset = 0

while True:

  query = f"""

    SELECT *

    FROM my_table

    ORDER BY id

    OFFSET {offset} ROWS FETCH NEXT {page_size} ROWS ONLY

  """

  cursor.execute(query)

  rows = cursor.fetchall()

  if not rows:

    break # Exit loop when no more rows

  # Process rows

  for row in rows:

    print(row)

  offset += page_size

4. Timeout Handling in Python

Set a query timeout or connection timeout in Python to avoid hanging queries. This can prevent long-running queries from causing issues.

# Example: Setting query timeout in cx_Oracle

import cx_Oracle

connection = cx_Oracle.connect("username", "password", "hostname/service_name")

cursor = connection.cursor()

# Set statement timeout (in milliseconds)

cursor.call_timeout = 5000 # Timeout after 5 seconds

5. Execute as Background Jobs in Oracle

For queries that require a lot of processing, consider offloading them to the database as background jobs using Oracle’s DBMS_SCHEDULER or DBMS_JOB. Once the job completes, fetch the results.

6. Close Idle Connections

Ensure Python scripts properly close idle database connections and cursors to avoid excessive usage of database resources:

cursor.close()

connection.close()

7. Increase Maximum Connect Time (If Possible)

If you have control over the database, you can increase the maximum connect time limit. Consult your DBA to modify the CONNECT_TIME parameter in the user profile:

ALTER PROFILE default LIMIT CONNECT_TIME UNLIMITED;

Note: This option should only be used if long-running queries are unavoidable and other optimizations have been applied.

By splitting queries into manageable chunks, optimizing the query, or adjusting the timeout settings, you can prevent the ORA-02399 error and ensure smooth query execution in Python.
