Question

How do I create or replace a procedure in JDBC?
I created the procedure in oracle, but I cannot replace the procedure from Java.

I have the following, but it does not work:

Statement stmt0 = conn.createStatement();
String query0 =
"CREATE OR REPLACE PROCEDURE my_proc " +
//blah blah blah
//blah blah blah
//blah blah blah
"END; " +
". " +
"run; ";
stmt0.execute(query0); 

From online tutorials, I see that i’m supposed to use something like:
cstmt = conn.prepareCall (SQL);
But I haven’t been able to make it work.

If you want to see more of my code, I will provide.

Answer 1

First of all, you can do this.

You want to prepare and execute from jdbc, to begin with.

Second, you need to cut off your last line with the “. ” and “run; ” which look like they are straight from SQL*Plus.

Note you have not put any newlines in your Java string, but that won’t matter. You seem to have added trailing spaces which is necessary.

I suggest logging or system.out.println of the string before you execute.

Don’t have a DBMS right now, but it should be something like

String sqlproc = 
    "CREATE OR REPLACE PROCEDURE FRED IS \n" +
    "BEGIN NULL; END FRED;";

System.out.println ("proc code: " + sqlproc);
Statement stmt = conn.prepareStatement (sqlproc);
stmt.execute();
