Oracle MERGE语句未使用DevArt dotConnect for Oracle进行“粘贴" [英] Oracle MERGE statement not 'sticking' using DevArt dotConnect for Oracle

问题描述

我在dotConnect for Oracle中使用Oracle MERGE语句，我知道MERGE本身可以在P-Sql和SQL Developer中运行，但是使用dotConnect和ExecuteNoQuery查询显然是成功的(没有抛出异常)但该表未进行任何更新或插入.

I'm using an Oracle MERGE statement in dotConnect for Oracle, I know that the MERGE itself is fine as runs in P-Sql and SQL Developer, yet using the dotConnect and ExecuteNoQuery the query is apparently successful (no exceptions thrown) but the table has had no updates or inserts taken place.

我可以将查询分为更新"和插入"，它们会保持正常.

I can break the query into an Update and an Insert and they stick ok.

有什么想法吗?

2)此代码:

OracleConnection conn = new OracleConnection("User Id=user;Password=pass;Server=dboracle;SID=sid;Direct=true");
conn.Open();
OracleTransaction t = conn.BeginTransaction();
OracleCommand comm = new OracleCommand(@"MERGE INTO ...");// place here your merge statement
comm.Transaction = t;
comm.Connection = conn;
comm.ExecuteNonQuery();
t.Commit();
