Applies to: 
SQL Server
To find rows that do not match a value, use the NOT operator.
To find rows that do not match a value
If you have not done so already, add the columns or expressions that you want to use within your search condition to the Criteria pane.
Locate the row containing the data column or expression to search, and then in the Filter grid column, enter the NOT operator followed by a search value.
For example, to find all the rows in a products table where the values in the product code column begin with a character other than "A," you can enter a search condition such as the following:
NOT LIKE 'A%'
