**SQL Query Description**
|
|
==========================
|
|
|
|
### Overview
|
|
|
|
The provided SQL query retrieves distinct rows from the `Process` table, ordered by a specific column.
|
|
|
|
### Breakdown
|
|
|
|
#### SELECT Clause
|
|
|
|
```sql
|
|
SELECT DISTINCTROW Process.*
|
|
```
|
|
|
|
* The `SELECT DISTINCTROW` clause specifies that only unique rows should be returned.
|
|
* The `Process.*` syntax selects all columns (`*`) from the `Process` table.
|
|
|
|
#### FROM Clause
|
|
|
|
```sql
|
|
FROM Process
|
|
```
|
|
|
|
* This clause specifies the table to retrieve data from, which is the `Process` table.
|
|
|
|
#### ORDER BY Clause
|
|
|
|
```sql
|
|
ORDER BY Mid$([PartNumber],4);
|
|
```
|
|
|
|
* The `ORDER BY` clause sorts the retrieved rows in ascending order based on a specified column.
|
|
* The `Mid$` function extracts a specific substring from the `PartNumber` column:
|
|
* `$(` denotes the start of an expression enclosed within parentheses.
|
|
* `Mid$` is likely an alias for the `SUBSTRING` or `LEFT`/`RIGHT` functions in SQL Server.
|
|
* The first argument to `Mid$` is `PartNumber`, and the second argument is `4`.
|
|
* The `4` means that 4 positions from the beginning of the string are extracted.
