pragma autonomous_transaction in a trigger

由 谁说我不能喝 提交于 2019-12-04 09:21:15
I have written a trigger on one table which deletes data from other table upon a condition. The trigger has pragma autonomous_transaction, and trigger works as intended. However, I do wonder if there can be any problems in future, say if data is inserted by multiple users/sources at the same time etc...Any suggestions? Source table t1: -------------------------------------------- | user_id | auth_name1 | auth_name2 | data | -------------------------------------------- | 1 | Name1 | Name2 | d1 | | 2 | Name3 | Name4 | d2 | | 3 | Name5 | Name1 | d3 | --------------------------------------------

问题 In one of our products we retrieve data from the Oracle database using stored procedures using the ODP.net managed driver. Every now and then (roughly every 1000 queries) we get the following exception: (ORA-12570: Network Session: Unexpected packet read error) ---> Oracle.ManagedDataAccess.Client.OracleException: ORA-12570: Network Session: Unexpected packet read error ---> OracleInternal.Network.NetworkException: ORA-12570: Network Session: Unexpected packet read error ---> System

由 与世无争的帅哥 提交于 2019-12-04 07:05:50
I'm new to using Oracle so I'm going off what has already been previously answered in this SO question . I just can't seem to get it to work. Here's the statement that I'm using: declare lastId number; begin INSERT INTO "DB_OWNER"."FOO" (ID, DEPARTMENT, BUSINESS) VALUES (FOO_ID_SEQ.NEXTVAL, 'Database Management', 'Oracle') RETURNING ID INTO lastId; end; When I call executeQuery the PreparedStatement that I have made, it inserts everything into the database just fine.
