**SQL Query Description**
|
|
==========================
|
|
|
|
This SQL query retrieves data from a table named `Process` and performs several string manipulation operations on the `PartName` column.
|
|
|
|
### Query Overview
|
|
|
|
The query selects specific columns from the `Process` table, filters rows based on the presence of certain substrings in the `PartName` column, and sorts the resulting data by multiple conditions.
|
|
|
|
### Selected Columns
|
|
|
|
* **cntl**: The position of the first occurrence of `"control"` in the lowercase `PartName`. If `"control"` is not found, a NULL value will be returned.
|
|
* **panl**: The position of the first occurrence of `"panel"` in the lowercase `PartName`. If `"panel"` is not found, a NULL value will be returned.
|
|
* **Expr1**: The leftmost 7 characters of the `partnumber`.
|
|
* **Expr2**: The uppercase version of the middle 8 characters (starting from position 8) of the `PartNumber`.
|
|
|
|
### Filtering Rows
|
|
|
|
The query filters rows where either `"control"` or `"panel"` is found in the lowercase `PartName`. This means that if a part has both `"control"` and `"panel"` substrings, it will be included in the result set.
|
|
|
|
### Sorting Results
|
|
|
|
The results are sorted by:
|
|
|
|
* The leftmost 7 characters of the `partnumber` (Expr1) in ascending order.
|
|
* The uppercase version of the middle 8 characters of the `PartNumber` (Expr2) in descending order.
|
|
|
|
### Example Use Case
|
|
|
|
This query might be used to analyze or process a list of parts that are part of control systems or panels, and then further filtering based on specific part numbers.
