What it does

SQL Query Description

Overview

This SQL query retrieves a distinct subset of data from the AddnlProc table based on specific conditions. The query is designed to extract unique records that meet certain criteria.

Breakdown

1. SELECT DISTINCTROW

The DISTINCTROW clause is used to select only one row for each group of rows with the same values in the specified columns. In this case, it ensures that all matching records are included in the results without duplicates.

2. FROM AddnlProc

The query specifies the table from which data is retrieved: AddnlProc. This is the source table where the relevant data is stored.

3. WHERE ((AddnlProc.Generated=Yes))

This clause filters the records to include only those where the value in the Generated column is equal to 'Yes'. The parentheses are used to group the condition, ensuring it is evaluated as a single boolean expression.

4. ORDER BY AddnlProc.PartNumber, AddnlProc.OPCode;

After filtering, the query sorts the remaining records based on two columns:

  • PartNumber
  • OPCode

The sorting order is ascending for both columns, ensuring that the results are presented in a consistent and organized manner.

Query Flow

  1. The database retrieves all rows from the AddnlProc table.
  2. The filtering condition (Generated = Yes) eliminates any records that do not meet this requirement.
  3. The distinct row clause ensures only unique combinations of values in the specified columns are returned.
  4. Finally, the sorted results are presented based on the PartNumber and OPCode columns.

Result

The resulting query returns a subset of data from the AddnlProc table that meets the specified conditions: distinct records with Generated set to 'Yes', sorted by both PartNumber and OPCode.
