What it does

SQL Query Description

Overview

This SQL query retrieves data from two tables: [Filtered Parts 3] and Process. The query filters the results to include only valid part numbers and selects specific columns. The output is transformed into a new table named [Util Selection 0].

Step-by-Step Breakdown

1. Column Aliasing

SELECT "x X X" AS BestSheetSet, [Filtered Parts 3].PN, Process.*
  • This line selects the first row of values as a literal string "x X X" and assigns it to a column alias BestSheetSet.
  • The Processed Parts 3 table is then selected for its PN (Part Number) value.
  • Finally, all columns from the Process table are selected using Process.*.

2. Joining Tables

FROM [Filtered Parts 3] LEFT JOIN Process ON [Filtered Parts 3].PN = Process.PartNumber
  • This line joins the [Filtered Parts 3] table with the Process table on a common column: PartNumber.
  • The join type is set to LEFT JOIN, which means that all records from the left table ([Filtered Parts 3]) will be included in the results, even if there are no matches in the right table.

3. Filtering

WHERE (((Process.PartNumber)\u003c\u003e""))
  • This line applies a filter to exclude any rows where Process.PartNumber is an empty string (\u003c\u003e "").
  • The triple parentheses around Process.PartNumber ensure that only non-empty strings are included in the results.

4. Sorting

ORDER BY Process.PartNumber, [Filtered Parts 3].PN;
  • This line sorts the filtered results by two columns:
    • First, by the PartNumber column of the Process table.
    • Second, by the PN (Part Number) value from the [Filtered Parts 3] table.

5. Output Transformation

INTO [Util Selection 0]
  • This line creates a new output table named [Util Selection 0].
  • The INTO clause is used to specify the destination for the query's results.

Example Use Case

This SQL query might be used in an inventory management system to retrieve part numbers with valid data from both the [Filtered Parts 3] and Process tables. The sorted output could help with identifying parts that need attention, such as those with no matching process information or incomplete data.

Output Format

The final output will have the following columns:

  • BestSheetSet: a constant string "x X X"
  • PN: the part number from [Filtered Parts 3]
  • The other columns from the Process table, sorted by PartNumber and then PN

Note: The exact column names and data types may vary depending on the actual schema of the tables involved.
