OJDBC ExecuteUpdate（）不返回任何内容

Question

I have a small java application, and i'm trying to execute a insert-select ( insert into table1 (column) select column from table2 ) using oracle jdbc driver, this sql comand inserts around 230k lines, in SQL Developer it runs in 30 minutes, but at java, when i called ExecuteUpdate() the method stuck and does not returns anything, more than 3 hours of execution, and the method remains stuck.

I tried to use execute() but the result was the same. I tried the drivers ojdbc5, ojdbc6 and ojdbc7, without success.

I found this question: Java - JDBC executeUpdate() not working but i can't change to weblogic.

anyone can help-me?

EDIT: The SQL command is successful executed, when i query this on sql developer, i can see the correct result, but in java application the method remais stuck.

Answer 1

It will be easier to understand problem, if i can see your code. First of all, executeUpdate("some query") function doesn't have return value. If i remember, you can assign int result = statement.executeUpdate("query") If you want return values, you can use ResultSet rs = statement.executeQuery("some query") executeUpdate() always stucks while inserting a lot of rows, but 3 hours is not normal. Please show your code :)
