What it does

SQL Query Description

This SQL query performs a complex join operation to retrieve data from multiple tables and populate two derived tables with the selected columns.

Table Names and Columns

• [Util Selection 3]: A table containing data for "Util Selection 3".
• [Sorted By Machines 1]: A table containing data for "Sorted By Machines 1".
• Process: A table containing additional process-related data.
• PRDNO, PartNumber: Common column names used in the join operations.

Query Steps

The query consists of three main steps:

Step 1: Left Join [Util Selection 3] with [Sorted By Machines 1]

This step performs a left join between the two tables on the PRDNO column, which is common to both tables. This ensures that all records from [Util Selection 3] are included in the results, even if there are no matching records in [Sorted By Machines 1].

Step 2: Left Join the result with Process

This step performs another left join between the previous result and the Process table on the PartNumber column. This ensures that all records from the first two tables are included in the results, even if there are no matching records in Process.

Result

The final result is populated into a derived table named [Steve's C1], which includes all columns (*) from both [Util Selection 3] and Process. The resulting table contains data from all three tables, joined on the common PRDNO and PartNumber columns.

Output

The query produces a table with two derived tables:

• [Steve's C1]: A table containing the selected columns from both [Util Selection 3] and Process.
• The original data in [Util Selection 3], [Sorted By Machines 1], and Process are also included.

Notes

The use of left joins ensures that all records from the first two tables are included in the results, even if there are no matching records in Process. This can be useful for maintaining data integrity and completeness.
