Question

I’m getting this error at this line:

Object[] results = (Object[])stmt.getArray(1).getArray();

Not sure what it means…

I can show the sql also…can someone explain what this error means…I also have that stac trace if needed

Not familiar with OracleCallableStatement, but shouldn’t that be

Object[] results = (Object[])(stmt.getARRAY(1).getArray());

oracle.jdbc.OracleCallableStatement#getARRAY(int) is OracleCallableStatement-specific, getArray() seems to be inherited from java.sql.CallableStatement#getArray(int).

Already said i’m not familiar with this, but getARRAY seems to fit better with the OracleTypes.ARRAY type you registered as out parameter.
