I have encountered the following access sql statements. Could someone tell me what the 20 AS Expr3 statement is doing in the select line?
Thanks in advance.

INSERT INTO tbl_ACH_Manual_Totals ( FunctionDate, ACHType, Status )
SELECT Date() AS Expr1, [intType] AS Expr2, 20 AS Expr3;

Actually "AS Expr3" assigns an alias to the column.

If you were doing a query (and not an INSERT), you would see "Expr3" as the column header.

Because this is an INSERT, all three aliases are bogus and have no effect upon the INSERT.

The query could just as easily have read:

INSERT INTO tbl_ACH_Manual_Totals ( FunctionDate, ACHType, Status )
SELECT Date(), [intType], 20;
