What it does

SQL Query Description

This SQL query retrieves specific data from the Process table based on certain conditions and formats the output.

Query Breakdown

1. Select Statement

The query selects all columns (*) from the Process table, but only for rows that meet the specified conditions.

SELECT Left$([PartNumber],7) AS prt, Right$([PartNumber],1) AS Rev, Process.*

Left$([PartNumber],7) extracts the first 7 characters from the PartNumber column and assigns it to a new column named prt.
Right$([PartNumber],1) extracts the last character from the PartNumber column and assigns it to a new column named Rev.
Process.* selects all columns (*) from the Process table.

2. WHERE Clause

The query filters rows based on two conditions:

WHERE (((Process.MetalType)=[Forms]![Utilization]![Combo12]) AND ((Left$([PartNumber],1))="9" Or (Left$([PartNumber],1))="8" Or (Left$([PartNumber],1))="7"))

((Process.MetalType)=[Forms]![Utilization]![Combo12]) filters rows where the value in the MetalType column matches the value in the Combo12 field of the Utilization form.
(Left$([PartNumber],1))="9" Or (Left$([PartNumber],1))="8" Or (Left$([PartNumber],1))="7" filters rows where the first character of the PartNumber column is either "9", "8", or "7".

3. INTO Clause

The query creates a new table named [Util Selection 1] to store the filtered data.

INTO [Util Selection 1]

4. ORDER BY Clause

The query sorts the output by two columns:

Left$([PartNumber],7) sorts the values in ascending order based on the first 7 characters of the PartNumber column.
Right$([PartNumber],1) sorts the values in descending order based on the last character of the PartNumber column.

ORDER BY Left$([PartNumber],7), Right$([PartNumber],1) DESC;

This ordering means that rows with more characters at the beginning (Left) will come first, and rows with different characters at the end (Right) will be sorted in descending order.
