Join them; it only takes a minute: Sign up DB Error=ORA-01407: cannot update (“XXX”.“XXX”.“VALUE”) to NULL. up vote 1 down vote favorite I have (simplified for http://www.dba-oracle.com/t_ora_01407_cannot_update_string_to_null.htm this question) a table 'TAB' with two columns 'id' (integer and not null in db) and 'value' (varchar and not null in db). I am using a java application to update 'value' column for multiple rows in one go (which is my requirement). I have used update statement with case and when keyword. The query is being generated at runtime depending on number of rows modified. The query works fine if http://stackoverflow.com/questions/10696514/db-error-ora-01407-cannot-update-xxx-xxx-value-to-null data is updated for all rows together, but it gives me error when updated for less rows. Say we have three rows with id = 1, 2 and 3 with values A ,B and C resp. When the query is fired for all three rows together then it works fine UPDATE TAB set value = CASE WHEN id = 1 THEN 'X' WHEN id = 2 THEN 'Y' WHEN id = 3 THEN 'Z' END But when the query is fired for less than three rows then I am encountering with a DB error. UPDATE TAB set value = CASE WHEN id = 1 THEN 'X' END Results in following error: DB Error=ORA-01407: cannot update ("XXX"."XXX"."VALUE") to NULL. I know this is happening because the 'value' column is not null in DB. I want to know whether the above query is trying to update all the remaining values with NULL? The query works fine if I add ELSE part as written below. UPDATE TAB set value = CASE WHEN id = 1 THEN 'X' ELSE TAB.value END Will the above query impact any performance issue, if there are multiple rows in DB. java sql database oracle share|improve this question edited May 22 '12 at 6:47 Shahzeb 2,99721837 asked May 22 '12 at
NULL values. To resolve ORA-01407, change the UPDATE statement to ensure that http://oraclebyte.blogspot.com/2011/06/fixing-ora-01407.html when a column is defined as NOT NULL then there is no attempt to UPDATE it with a NULL value. In case of an update statement with a correlated sub-query, one solution to the ORA-01407 error in SQL is to check for NULL rows using the where exists clause. update cannot update ORDERS a set a.amount = (select b.qty * b.item_price from ITEM b where a.item_id = b.item_id);Error: ORA-01407: cannot update ("SCHEMA_NAME"."ORDERS"."AMOUNT") to NULL. Replacing the above update statement with this one will remove the ORA-01407 error: update ORDERS a set a.amount = (select b.qty * b.item_price from ITEM cannot update to b where a.item_id = b.item_id) where exists (select 1 from ITEM b where a.item_id = b.item_id); commit; Posted by wedo at 1:46 PM Email ThisBlogThis!Share to TwitterShare to FacebookShare to Pinterest 3 comments: UnknownAugust 18, 2016 at 9:21 PMIf i do like the above your solution, then I am getting " ORA-01427 single-row subquery returns more than one row "ReplyDeleteUnknownAugust 18, 2016 at 9:22 PMIf i do like the above your solution, then I am getting " ORA-01427 single-row subquery returns more than one row "ReplyDeleteAdityaSoftwareOctober 16, 2016 at 8:31 PMyou can try nvlupdate ORDERS a set a.amount = nvl((select b.qty * b.item_price from ITEM b where a.item_id = b.item_id),0) ReplyDeleteAdd commentLoad more...
