    Any ideas why this isn't working:
    SEMrush
    
    SELECT
    `Item Type`,
    COUNT(*),
    FROM Stock 
    WHERE `Use Commenced By` = ""
    GROUP BY `Item Type`
    
    Code (markup):
    But this works fine:
    
    SELECT
    `Item Type`,
    COUNT(*),
    FROM Stock 
    GROUP BY `Item Type`
    
    Code (markup):

    Try using double quotes in the WHERE clause. Other than that, IDK.

    If that's what you get, whatever you're using to run that query "fixes" the quotes. Use another method / program / whatever.

    One thing I would advise against is using spaces in field names. Instead the better way is to use Camel Cased or Lower Case for the titles:

    Item_Type/item_type
    Use_Commenced_By/use_commenced_by

    I am not saying that it is wrong to have spaces, just not the norm.

    Other than that the original statement is fine, you use backticks to escape the column name in where not single quotes. Are you sure that the result set you are expecting exist?

    Also remove the comma after the last field you want count() as it is not needed.
