Question

How a function/procedure can be called inside a insert statement without command parameters. e.g.

Insert into myTable (....) values (1,2,mySP_or_mySDF, 3,4)

Answer 1

You can also use INSERT INTO... SELECT

INSERT INTO myTable (col1, col2, col3....)
SELECT 1, 2, mySP_or_mySDF(), 3, 4

If you want to INSERT data from a stored procedure, then you will need to create a temp table and insert the result into the temp table first, then you can use the result to insert into the final table.
