**SQL Query Description**
|
|
==========================
|
|
|
|
This SQL query retrieves specific data from two tables: `Scott'sQ1` and `Process`. The query uses various aggregation functions, joining the two tables based on a common column, and applies conditions to filter the results.
|
|
|
|
### Table Join and Data Retrieval
|
|
|
|
The query joins the `Scott'sQ1` table with the `Process` table on the condition that the `PartNumber` column in both tables is equal. The joined table contains data from both sources, allowing for aggregation and filtering operations.
|
|
|
|
The query selects various columns:
|
|
|
|
* `Left$([PartNumber],7)`: Truncates the `PartNumber` to 7 characters from the left.
|
|
* `First(Right$(Trim$([PartNumber]),1))`: Removes the first character from the right side of the trimmed `PartNumber`.
|
|
* `First([Scott'sQ1].PartNumber)`, `First([Scott'sQ1].Prime)`: Retrieves the unique value for each column.
|
|
* `Left$([PartNumber],1)`: Truncates the `PartNumber` to 1 character from the left.
|
|
* `[Scott'sQ1].MachineName`, `[Scott'sQ1].Expr1`, `Process.PartsPerBlank`: Retrivees data from these columns directly.
|
|
|
|
### Grouping and Filtering
|
|
|
|
The query groups the results by:
|
|
|
|
* Truncated `PartNumber` (`Left$([PartNumber],7)`).
|
|
* `MachineName`.
|
|
* `Expr1`.
|
|
* `PartsPerBlank`.
|
|
|
|
A filter condition is applied to the grouped data using the `HAVING` clause. The filter checks if the first character of the truncated `PartNumber` is equal to "9". Only rows that satisfy this condition are included in the final results.
|
|
|
|
### Sorting
|
|
|
|
The query sorts the filtered results by:
|
|
|
|
* Truncated `PartNumber` (`Left$([PartNumber],7)`).
|
|
* First character removed from trimmed `PartNumber` (`First(Right$(Trim$([PartNumber]),1))`).
|
|
|
|
**Example Output**
|
|
-----------------
|
|
|
|
| parts | Expr2 | FirstOfPartNumber | FirstOfPrime | Expr3 | MachineName | Expr1 | PartsPerBlank |
|
|
| ----- | ---------- | ----------------- | -------------- | -------- |------------- | --------- | ------------ |
|
|
| ... | ... | ... | ... | ... | ... | ... | ... |
|
|
|
|
**Notes**
|
|
|
|
* The `SELECT DISTINCTROW` clause is used to ensure that each row in the result set is unique.
|
|
* The `First(Right$(Trim$([PartNumber]),1))` expression uses the `RIGHT` function to remove the first character from the right side of the trimmed string, and the `FIRST` aggregation function to retrieve the resulting value.
|
|
* The use of `$` in column names suggests that these are SQL Server-specific identifiers.
