What it does

SQL Query Description

Overview

This SQL query retrieves data from two tables: [SP Make Latest 2] and Process. The query joins these tables based on a common column, filters the results to specific warehouses, and returns the desired columns.

Step-by-Step Explanation


  1. Select Columns

SELECT [SP Make Latest 2].Partnumber, Process.Warehouse

   This line selects two columns from the query:
   * `[SP Make Latest 2].Partnumber`: The part number column from the `[SP Make Latest 2]` table.
   * `Process.Warehouse`: The warehouse column from the `Process` table.

2. **Join Tables**
   ```sql
FROM [SP Make Latest 2] LEFT JOIN Process ON [SP Make Latest 2].Partnumber = Process.PartNumber

This line joins the [SP Make Latest 2] and Process tables based on a common column:

  • LEFT JOIN: This type of join returns all records from the left table ([SP Make Latest 2]) and matching records from the right table (Process). If there's no match, it still returns the record with NULL values.
  • ON [SP Make Latest 2].Partnumber = Process.PartNumber: The join condition is set to match rows where the Partnumber column in both tables has the same value.
  1. Filter Results

WHERE (((Process.Warehouse)="02"));

   This line filters the joined results to only include records where the warehouse is "02".

### Example Use Case
--------------------

This query might be used to retrieve information about a specific part number that was manufactured in Warehouse 02. The result set would contain all relevant data for that part, including its part number and warehouse location.

### Note
--------

The use of double quotes around the value `"02"` is not recommended in standard SQL practice, as it can lead to issues with quote nesting and string concatenation. A more conventional way to filter on a specific value would be to use a single equals sign (`=`), like this:
```sql
WHERE Process.Warehouse = '02'

However, the original query may still be valid depending on the specific database management system or application being used.
