|
**SQL Code Description**
|
|
=========================
|
|
|
|
This SQL code snippet performs the following operations on a table named `[SG Trash Query]`:
|
|
|
|
### 1. Selecting Data
|
|
|
|
The query selects data from the specified table, including columns `Part`, `PartNumber`, and performing calculations on `PartNumber`.
|
|
|
|
### 2. Calculating Right-Trimmed Part Number
|
|
|
|
The code uses the `Right$` function to extract the last character from the `PartNumber` column, and then applies the `Trim$` function to remove any leading or trailing whitespace. The result is stored in a new calculated column named `Rev`.
|
|
|
|
### 3. Finding Maximum Values
|
|
|
|
For each group of rows with the same value in the `Part` column, the query uses the `Max` aggregation function to find the maximum values for two columns:
|
|
|
|
* `Rev`: The last character of the `PartNumber` column (after right-trimming)
|
|
* `PartNumber`: The original `PartNumber` column
|
|
|
|
These maximum values are stored in new calculated columns named `Rev` and `MaxOfPartNumber`, respectively.
|
|
|
|
### 4. Grouping and Sorting Data
|
|
|
|
The query groups the data by the `Part` column, which means that rows with the same value in this column will be treated as a single group. The results are then ordered based on the values in the `Part` column.
|
|
|
|
### 5. Returning Results
|
|
|
|
Finally, the query returns the grouped and sorted data, including the calculated columns `Rev` and `MaxOfPartNumber`, as well as the original `Part` and `PartNumber` columns.
