SQLJ problem with DML

Question

When try to Update record with sqlj I've got no result !!! Data remains unchanged ??
Does anybody have same problem ???
(I use default context).

Answer 1

Good point! You issue a commit in SQLJ with:
#sql { COMMIT };
Remember that:
- JDBC creates connections with autocommit on (except for the JServer session connection)
- the Oracle.connect() calls create connections with autocommit off
Some additional tips:
(1) You can use an ExecutionContext to see how many rows got updated.
import sqlj.runtime.ExecutionContext;
ExecutionContext ec=new ExecutionContext();
#sql [ec] { UPDATE table SET ... WHERE ... };
System.out.println("Updated "+ec.getUpdateCount()+" rows.");
(2) Remember that if the WHERE clause selects no rows, then 0 rows get updated and you will also NOT see a SQLException.
(3) If your WHERE clause compares any CHAR columns to Java strings, it very likely will not work: you have to blank-pad the Java strings if you want the comparison to succeed. Or you can declare the column as VARCHAR2. Or you could use a LIKE comparison and append a "%" to the Java string.
