**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**
|
|
```sql
|
|
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.
|
|
|
|
3. **Filter Results**
|
|
```sql
|
|
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.
