What it does

SQL Query Description

Purpose

This SQL query retrieves specific data from the PressBrakeOPs table based on a filter condition related to a part number.

Query Breakdown

Select Clause

SELECT PressBrakeOPs.PartNumber, 
       PressBrakeOPs.OpCode, 
       PressBrakeOPs.Step, 
       PressBrakeOPs.Angle, 
       PressBrakeOPs.Comment, 
       PressBrakeOPs.Breaks, 
       PressBrakeOPs.Hits

The query selects multiple columns from the PressBrakeOPs table:

  • PartNumber: The unique identifier for a part.
  • OpCode: An operation code related to the part.
  • Step: A step or process related to the part's operation.
  • Angle: An angle associated with the part's operation.
  • Comment: A comment or note about the part's operation.
  • Breaks and Hits: Two unknown quantities.

Filter Condition

FROM PressBrakeOPs
WHERE (((PressBrakeOPs.PartNumber)=[Forms]![Process Sheet]![PartNumber]));

The query filters the data based on a condition that relates to the part number. The filter is applied using the WHERE clause:

  • The condition checks if the value in the PartNumber column of the PressBrakeOPs table matches the selected value from:
    • Forms![Process Sheet]: A form or dialog box containing a process sheet.
    • [PartNumber]: The part number displayed on the process sheet.
  • The syntax for accessing values in this manner is specific to Access, a popular database management system.

Notes

  • This query uses a syntax that may not be compatible with all SQL dialects or database systems. It appears to be written in Access's Jet SQL dialect.
  • Without more context about the PressBrakeOPs table and its structure, it is difficult to provide more detailed information about what data the query is intended to retrieve.

Recommended Practice

For better readability and maintainability, consider rewriting this query using a more standard syntax for filtering data:

SELECT 
    PressBrakeOPs.PartNumber,
    PressBrakeOPs.OpCode,
    PressBrakeOPs.Step,
    PressBrakeOPs.Angle,
    PressBrakeOPs.Comment,
    PressBrakeOPs.Breaks,
    PressBrakeOPs.Hits
FROM 
    PressBrakeOPs
WHERE 
    PressBrakeOPs.PartNumber = Forms![Process Sheet]![PartNumber]
