I'm attempting to insert a datetime('2013-08-30 19:05:00') value into a SQL server database table column(smalldatetime) and the value stays "NULL" after the insert.
I'm doing this to 6 other columns that are the exact same type. What is this only occuring on one column? I've triple checked that the names of the columns are correct. Any ideas?
Assuming the situation is as you describe
CREATE TABLE T
(
S SMALLDATETIME NULL
)
INSERT INTO T
VALUES('2013-08-30 19:05:00')
SELECT *
FROM T /*Returns NULL*/
There are only two ways I can think of that this can happen.
1) That is an ambiguous datetime format. Under the wrong session options this won't cast correctly and if you have some additional options OFF it will return NULL rather than raise an error (e.g.)
SET LANGUAGE Italian;
SET ansi_warnings OFF;
SET arithabort OFF;
INSERT INTO T
VALUES('2013-08-30 19:05:00')
SELECT *
FROM T /*NULL inserted*/
2) You may have missed the column out in an INSTEAD OF trigger, or have an AFTER trigger that actually sets the value back to NULL.
