- [Forms]![Process Sheet]![PartNumber] (Empty)
|
|
## What it does
|
|
**SQL Query Description**
|
|
=========================
|
|
|
|
This SQL query retrieves specific data from the `Machines` table based on a condition specified in the form control `[PartNumber]`.
|
|
|
|
**Query Breakdown**
|
|
------------------
|
|
|
|
### SELECT Clause
|
|
|
|
The `SELECT` clause specifies the columns to be retrieved:
|
|
|
|
* `Machines.PartNumber`: The part number of the machine.
|
|
* `Machines.MachineName`: The name of the machine.
|
|
* `Machines.CycleTime`: The cycle time of the machine.
|
|
* `Machines.Tool`: The tool used for the machine.
|
|
* `Machines.Prime`: A flag indicating whether the machine is prime (TRUE or FALSE).
|
|
|
|
### FROM Clause
|
|
|
|
The `FROM` clause specifies the table to retrieve data from:
|
|
|
|
* `Machines`: The `Machines` table.
|
|
|
|
### WHERE Clause
|
|
|
|
The `WHERE` clause applies a condition to filter the data:
|
|
|
|
* `(((Machines.PartNumber)=[Forms]![Process Sheet]![PartNumber]))`: This is an example of an embedded expression that compares the part number in the database with the value entered in the form control `[PartNumber]`.
|
|
|
|
**Note**: The use of square brackets (`[]`) around the form control references suggests that this query is part of a larger application built using Microsoft Access or another GUI-based database system.
|
|
|
|
**Example Use Case**
|
|
--------------------
|
|
|
|
This query could be used to display specific machine data on a report or in a table, filtered by a particular part number. The value entered in the form control `[PartNumber]` would determine which machines are displayed in the result set.
|
|
|
|
**Best Practices and Suggestions**
|
|
-----------------------------------
|
|
|
|
* Consider using parameterized queries to avoid SQL injection vulnerabilities.
|
|
* Use meaningful column aliases instead of `PartNumber`, `MachineName`, etc.
|
|
* Add a comment or description above the query to explain its purpose and any assumptions made.
