Snippet Name: Inserting into SELECT statement

Description: You can use a select-statement within an INSERT statement to insert zero, one, or more rows into a table from the result table of the select-statement.

One use for this kind of INSERT statement is to move data into a table you created for summary data.

INSERT INTO (<SELECT Statement>);
 
  INSERT INTO CORPDATA.EMPTIME
     (EMPNUMBER, PROJNUMBER, STARTDATE, ENDDATE)
  SELECT EMPNO, PROJNO, EMSTDATE, EMENDATE
    FROM CORPDATA.EMPPROJACT
 
--Notes:
 
-- 1. The number of columns implicitly or explicitly listed in the INSERT statement must equal the number of columns listed in the select-statement.
-- 2. The data in the columns you are selecting must be compatible with the columns you are inserting into when using the INSERT with select-statement.
-- 3. In the event the select-statement embedded in the INSERT returns no rows, an SQLCODE of 100 is returned to alert you that no rows were inserted. If you successfully insert rows, the SQLERRD(3) field of the SQLCA has an integer representing the number of rows SQL actually inserted. This value is also available from the ROW_COUNT diagnostics item in the GET DIAGNOSTICS statement.
-- 4. If SQL finds an error while running the INSERT statement, SQL stops the operation. If you specify COMMIT (*CHG), COMMIT(*CS), COMMIT (*ALL), or COMMIT(*RR), nothing is inserted into the table and a negative SQLCODE is returned. If you specify COMMIT(*NONE), any rows inserted before the error remain in the table.
