## 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").
