What it does

SQL Query Description

Overview

This SQL query retrieves a distinct row from the K_NUM_1 table where the value of the Machine column matches one of eight specified machine codes.

Breakdown

Select Statement

SELECT DISTINCTROW K_NUM_1.*

SELECT: Retrieves data from the database.
DISTINCTROW: Ensures that only unique rows are returned, eliminating duplicates.
K_NUM_1.*: Selects all columns (*) from the K_NUM_1 table.

From Clause

FROM K_NUM_1

Specifies the table (K_NUM_1) to retrieve data from.

Where Clause

WHERE ((K_NUM_1.Machine="C-1000" Or K_NUM_1.Machine="C-2000" ... Or K_NUM_1.Machine="C-9000"));

Filters the results to only include rows where the Machine column value matches one of the specified machine codes.
The Or operator (or) is used in conjunction with multiple conditions, creating a logical OR expression.
Each condition checks if the Machine column equals a specific machine code (e.g., "C-1000").

Example Use Case

This query can be used to retrieve unique records from the K_NUM_1 table where the machine type is known. For instance, if you need to report on all instances of machines with specific codes, this query would provide a concise and efficient way to do so.

Notes

This query assumes that the Machine column in the K_NUM_1 table contains only string values matching the specified machine codes.
Using an OR operator within the WHERE clause can lead to performance issues if the number of conditions is large. Consider optimizing this query by using indexes on the Machine column or rewriting it as a series of separate queries with AND operators instead of OR operators.
