What it does

SQL Query Explanation

Overview

This SQL query retrieves specific data from two tables, test1 and Process, based on the presence of certain strings in the PartName column.

Table Descriptions

• test1: A table containing information about parts, with columns:
  • PartNumber: The unique identifier for each part.
  • PartName: The name of each part.
• Process: A table related to the process of manufacturing or inspecting these parts, with columns:
  • PartNumber: The same as in the test1 table, linking it to the corresponding part.
  • PartName: The same as in the test1 table, used for joining purposes.

Query Logic

The query consists of three main components:

1. Joining Tables: It performs a LEFT JOIN between the test1 and Process tables based on the matching PartNumber. This allows the query to access data from both tables.
2. String Inquiries: It uses the InStr function to check if specific strings are present in the PartName column of both tables:
   • (InStr([PartName],"CONTROL")\u003c\u003e0): Checks for the presence of the string "CONTROL" within the part name.
   • (InStr([PartName],"PANEL")\u003c\u003e0): Checks for the presence of the string "PANEL" within the part name.
3. Filtering Results: The query applies two conditions to filter the results:
   • Only rows where both strings ("CONTROL" and "PANEL") are present in the PartName column are included.

Query Output

The final output of this SQL query will be a set of rows containing:

• PartNumber: From the test1 table.
• PartName: From the Process table, with the joined data from both tables.
• PressBrake: From the Process table (not part of the original query logic but included in the output due to the join).
• Two additional columns:
  • Expr1: The position of "CONTROL" within the part name. If "CONTROL" is not present, it will be represented as 0.
  • Expr2: The position of "PANEL" within the part name. If "PANEL" is not present, it will be represented as 0.

Usage Scenario

This query might be used in a manufacturing or quality control environment to identify parts that have undergone specific processes (e.g., press brake operations) and contain certain keywords ("CONTROL" and/or "PANEL").
