What it does

SQL Query Description

Overview

This SQL query retrieves data from two tables, [Util Selection 2] and [Util Selection 3], based on a join condition. The query uses a LEFT JOIN to include all records from the left table ([Util Selection 2]) even if there are no matching records in the right table ([Util Selection 3]). The WHERE clause filters the results to only include rows where the PHANT column in [Util Selection 3] is null.

Breakdown

1. SELECT [Util Selection 2].* FROM [Util Selection 2]

This line selects all columns (*) from the [Util Selection 2] table and assigns the alias .*. This is equivalent to selecting every column in the table, including any that may not have been explicitly named.

2. LEFT JOIN [Util Selection 3] ON [Util Selection 2].prt = [Util Selection 3].PRDNO

This line performs a LEFT JOIN between the [Util Selection 2] and [Util Selection 3] tables based on the join condition:

• The left table is [Util Selection 2].
• The right table is [Util Selection 3].
• The join column in the left table is prt.
• The join column in the right table is PRDNO.

The resulting table contains all columns from both tables. If there are no matching rows in the right table, the result will contain null values for the columns from the right table.

3. WHERE ((([Util Selection 3].PHANT) Is Null))

This line filters the results to only include rows where:

• The value in the PHANT column of the [Util Selection 3] table is null.
• The Is Null keyword is used to check for null values.

The query will return all columns from the left table ([Util Selection 2]) for which there are no matching rows in the right table ([Util Selection 3]) and where the PHANT column is null.
