What it does

SQL Query Description

Overview

This SQL query retrieves data from the Process table and performs various string manipulations to extract specific information.

Query Breakdown

1. SELECT Clause

The SELECT clause specifies the columns that will be retrieved from the database. In this case:

Left$([PartNumber],7): Extracts the first 7 characters of the PartNumber column and returns them as a string. The $ symbol is used to denote string concatenation in SQL Server.
Trim$(Right$([PartNumber],1)): Removes the last character (if any) from the PartNumber column using the TRIM function with the $ symbol for string concatenation. This effectively extracts the rev number, which is the last digit of the part number.

2. FROM Clause

The FROM clause specifies the table that contains the data to be retrieved:

Process: The table from which to retrieve data.

3. ORDER BY Clause

The ORDER BY clause sorts the retrieved data in ascending order based on two columns:

Left$([PartNumber],7): The first 7 characters of the part number.
Trim$(Right$([PartNumber],1)): The last digit (rev number) of the part number. This column is sorted in descending order.

4. AS Clause

The AS clause assigns aliases to the extracted columns:

prt: Alias for the first 7 characters of the part number.
Rev: Alias for the rev number (last digit of the part number).
PartNumber: Alias for the original PartNumber column.

5. ORDER BY Syntax

The specific syntax used for sorting in this query is an extension to the standard SQL syntax, allowing for sorting on multiple columns with a custom order.

Example Output

prt	Rev	PartNumber
XYZ1234	4	XYZ1234
XYZ1233	3	XYZ1233
...	...	...

The output will show the first 7 characters of each part number followed by the last digit (rev number) in descending order.
