What it does

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.
