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

### Overview

This SQL query retrieves distinct rows from a table named `UniversalQ` where the value of the `MetalType` column matches the specified parameter `MATER`.

### Parameters

*   `PARAMETERS MATER`: This is a SQL input parameter with a data type of `Text` and a maximum length of 255 characters. The purpose of this parameter is to specify the metal type that will be used to filter the results.

### Query Logic

1.  **SELECT DISTINCTROW**: This keyword selects only distinct rows from the result set, ensuring that each row retrieved contains unique values.
2.  `UniversalQ.*`: This specifies that all columns (`*`) from the `UniversalQ` table should be included in the query's result set.

    The `./* ` syntax after a column name tells SQL Server to return all columns. If you only want specific columns, replace `*` with the desired column names.
3.  `FROM UniversalQ`: This specifies that the data should be retrieved from the `UniversalQ` table.
4.  `WHERE ((UniversalQ.MetalType = [MATER]))`: This filters the results to include only rows where the value of the `MetalType` column matches the value specified in the input parameter `MATER`. The use of parentheses ensures that the comparison is done before matching any values with `MATER`.

### Example Use Case

This query can be used in a scenario where you need to retrieve distinct metal types from a database table. For instance, if you're managing inventory or tracking materials, this query would allow you to filter results based on specific material types.

```sql
-- Specify the metal type as an input parameter.
DECLARE @MetalType nvarchar(255) = 'Copper';

-- Run the query with the specified metal type.
SELECT DISTINCTROW UniversalQ.*
FROM UniversalQ
WHERE ((UniversalQ.MetalType = @MetalType));
```

In this example, we're using a `DECLARE` statement to define and initialize an input parameter `@MetalType`, which is assigned the value `'Copper'`. We then run the query with this input parameter.
