I always endup doing this to cover all situations where @variable can be empty or null,
IF(COALESCE(@variable,'') <> '')
BEGIN
END
Is this the most optimal way to check this?
If its a variable, then it shouldn’t matter. If you are doing a similar filter on a column of a table, then I would recommend:
WHERE Column IS NOT NULL OR Column <> ''as it mantains the use of a possible index on that column.
