Can someone please explain to me what the # symbol means in MS SQL Code.

I’ve tried Googling it, and even searching on StackOverflow, but can’t seem to find the answer.

I feel like an idiot – having one of “those” days. Please help.

    They normally prefix temporary tables.

    From the docs….

    Prefix local temporary table names
    with single number sign (#table_name),
    and prefix global temporary table
    names with a double number sign
    (##table_name).
