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$([PartNumber],7)
: Truncates thePartNumber
to 7 characters from the left.First(Right$(Trim$([PartNumber]),1))
: Removes the first character from the right side of the trimmedPartNumber
.First([Scott'sQ1].PartNumber)
,First([Scott'sQ1].Prime)
: Retrieves the unique value for each column.Left$([PartNumber],1)
: Truncates thePartNumber
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 theRIGHT
function to remove the first character from the right side of the trimmed string, and theFIRST
aggregation function to retrieve the resulting value. - The use of
$
in column names suggests that these are SQL Server-specific identifiers.
