SQL Query Description

Overview

This SQL query performs a left outer join on two tables, [Process by material] and Process, based on the matching values in the PartNumber column. The query extracts the first 7 characters from the PartNumber column in the [Process by material] table and joins it with the corresponding records from the Process table.

Breakdown

• SELECT Clause

  • LEFT$([PartNumber],7) AS PN: This line selects the first 7 characters of the PartNumber column from the [Process by material] table. The LEFT$() function is used to extract a specified number of characters from the beginning of the string. The resulting column is aliased as PN.
  • Process.*: This line selects all columns (*) from the Process table.

• FROM Clause

  • [Process by material]: This line specifies the first table to be queried, which is [Process by material].

• JOIN Clause

  • LEFT JOIN Process ON [Process by material].PN = Process.PartNumber: This line performs a left outer join on the two tables. The join condition is based on the matching values in the PartNumber column:
    • [Process by material].PN refers to the aliased PartNumber column from the first table.
    • Process.PartNumber refers to the original PartNumber column from the second table.

Result

The result of this query will be a table that includes all records from the [Process by material] table, with their corresponding matching records from the Process table. The PN alias represents the first 7 characters of the PartNumber column in the [Process by material] table.

Example Use Case

This query can be used to analyze processes based on part numbers. For instance, it could help identify all processes that have a specific part number or group parts with similar process names.
