Question

I have been searching for a query to compare values in single rows in the same table.

Example table:

SKU        Description   SKU   Category  
173406926  Widgets       1734  
137406927  Widgets-Blue  1734

I need to find the rows where the SKU number does not start with the SKU Category number (as in row two above)

Answer 1

SELECT  *
FROM    tableName
WHERE   NOT (SKU LIKE CONCAT(`SKU Category`, '%'))
