## What it does
**SQL Query Description**

This SQL query retrieves distinct rows from the `Process` table, joined with the `Metals` and `AddnlProc` tables. The query filters data based on specific conditions.

### Joined Tables

The query joins three tables:

*   **Process**: contains process information
*   **Metals**: contains metal information
*   **AddnlProc**: contains additional processing information (e.g., operations, descriptions)

### Selected Columns

The query selects the following columns from the joined tables:

*   `Process` table:
    *   `PartNumber`
    *   `PartName`
    *   `RevisionLevel`
    *   `IssueNumber`
    *   `IssueDate`
    *   `PreviousIssue`
    *   `PreviousDate`
    *   `Programmer`
    *   `PrintSize`
    *   `History`
    *   `MetalType`
    *   `CutType`
    *   `PrimeMachine`
    *   `GrainDir`
    *   `Debur`
    *   `FirstDim`
    *   `SecDim`
    *   `PartHeight`
    *   `BotTrimCut`
    *   `TopTrimCut`
    *   `PartWidth`
    *   `BlankSize`
    *   `PartSize`
    *   `GrossWt`
    *   `ActualWt`
    *   `Utilization`
    *   `SheetSize`
*   **Metals** table:
    *   `MetalName`
    *   `Gauge`
    *   `Density`
*   **AddnlProc** table:
    *   `ID`
    *   `Generated`
    *   `OPCode`
    *   `Description`
    *   `WC1`, `WC2`, `WC3`, and `WC4` ( likely code snippets or comments)
    *   `Machine`
    *   `CycleTime`
    *   `RunStd`

### Filtering Conditions

The query applies the following filtering conditions:

*   The `PartNumber` must match a value in the `[Forms]![Data Sheet Select]![Field1]` field (presumably a dropdown or text input).
*   The first character of the `OPCode` column (`Left([OPCode], 1)`) must not be " "*", "!", "@", or "$".
*   The remaining characters of the `OPCode` column must match the specified filtering criteria.

### SELECT DISTINCTROW Clause

The query uses the `SELECT DISTINCTROW` clause to retrieve only unique rows from the joined tables, based on the columns selected in the query.

### Query Structure

The query structure consists of:

1.  **Inner joins**: The query joins the `Process`, `Metals`, and `AddnlProc` tables using the corresponding keys.
2.  **Filtering conditions**: The query applies filtering conditions to the joined data.
3.  **Selected columns**: The query selects specific columns from the joined tables.

Overall, this query retrieves process information with associated metal and additional processing details, filtered based on a specified part number and OPCode criteria.
