JDBC CallableStatement and Oracle SYS_REFCURSOR IN parameters?
- by deebo
Pretty much what it says in the title, how the hell is this supposed to be done?
Basically i need to pass a null (empty?) ref cursor as an IN parameter to a stored procedure.
/** spring's PreparedStatementSetter#setValues(...) */
public void setValues(PreparedStatement ps) throws SQLException {
CallableStatement cs = (CallableStatement) ps;
cs.setString(1,"constant");
//this is the IN param
cs.setNull(2, OracleTypes.CURSOR);
//this is the OUT param
cs.registerOutParameter(3, OracleTypes.CURSOR);
}
And this fails with:
caused by: java.sql.SQLException: Unsupported feature: sqlType=-10

at oracle.jdbc.driver.OraclePreparedStatement.setNullInternal(OraclePreparedStatement.java:4161)
at oracle.jdbc.driver.OracleCallableStatement.setNull(OracleCallableStatement.java:4472)
I'm at a loss here, tried several different ways to do this, but I couldn't find any examples about this and have no idea how to do it properly.
