Обсуждение: Bug and Bugfix for the jdbc-driver

In the datamodeller of JBuilder 4, only the systemtables are shown.
The Problem is in the funtion

  getTableTypes() in the file
src/interfaces/jdbc/org/postgresql/jdbc2/DatabaseMetaData.java

This function should return a list of TableTypes. But it resturns a list of
6 Identical entries
(SYSTEM INDEX) instead.

I exchanged 2 lines of code to fix the problem. it works fine at my place.

here is the modified funtion:

  public java.sql.ResultSet getTableTypes() throws SQLException
  {
    Field f[] = new Field[1];
    Vector v = new Vector();
    f[0] = new Field(connection,new String("TABLE_TYPE"),iVarcharOid,32);
    for(int i=0;i<getTableTypes.length;i++) {
      byte[][] tuple = new byte[1][0];
      tuple[0] = getTableTypes[i][0].getBytes();
      v.addElement(tuple);
    }
    return new ResultSet(connection,f,v,"OK",1);
  }

The  lines
    for(int i=0;i<getTableTypes.length;i++) {
      byte[][] tuple = new byte[1][0];
are exchanged.

This Fix doesn't solve all problems with JBuilder4.

This was fixed about 6 months ago. What version of the driver are you using?

This was the exact fix (actually it also occurs in another method as well).

No, althought the current development driver is working with my copy of
JBuilder4.
