IBM DB2，SQL和Java PreparedStatement。 如何：选择WHERE ROWID =

Question

    String updateSQL = "UPDATE FILE_CLOB_VERSION SET WS_ACHIEVED = ? WHERE ROWID = ?";
    PreparedStatement stmt = con.prepareStatement(updateSQL);   
    ...
    stmt.setString(1, "PUBLISHED");
    stmt.setRowId(2,new RowId() {

        @Override
        public byte[] getBytes() {
            return "4fa78fb773723b13e90401255bdc0100000000001201".getBytes();
        }
    });

The above is not working, getting :

Exception in thread "main" java.lang.AbstractMethodError:

java/sql/PreparedStatement.setRowId(ILjava/sql/RowId;)

I tried to use String:

    stmt.setString(2, "4fa78fb773723b13e90401255bdc0100000000001201");

Exception in thread "main" com.ibm.db2.jcc.b.SqlException: [ibm][db2][jcc][1083][10403] Unallowed convertion.

I also tried to change the updateSQL:

String updateSQL = "... ROWID = ROWID(X?)";

and use setString ... no luck. If you query the database without preparedstatement outside of java environment, the query would look like this:

UPDATE FILE_CLOB_VERSION SET WS_ACHIEVED = 'PUBLISHED' WHERE ROWID = ROWID(X'4fa78fb773723b13e90401255bdc0100000000001201')

How should my preparedstatement look like?

The ROWID column is of datatype ROWID:

COLUMN_NAME DATA_TYPE TYPE_NAME

ROWID 1111 ROWID

你有尝试过吗？

stmt.setBytes(2, "4fa78fb773723b13e90401255bdc0100000000001201".getBytes());
