Create cursor with data from multiple tables

Question

Hi,
I need to create a cursor that contains fields from different tables.
For example:
Table 1                  Table 2                    Table 3                Table 4
Col 1 (PK)              Col 2 (Pk)                  Col 4 (Pk)            Col 9 (PK)
Col 2                     Col 3  (Pk)               Col 5 (PK)            Col 11
Col 3                     Col 6                     Col 8                 Col 12
Col 4                     Col 7                     Col 9
Col 5                                               Col 10
Col 13
Col 14I've created the following:
CURSOR c_test IS
   SELECT a.col 1,
                a.col 13,
                a.col 14
                b.col 6
                b.col 7
                c.col 8
                c.col 10
                d.col 9
                d.col 11
   FROM table1 a, table2, b, table3 c, table4 d
   WHERE (b.col 2,  b.col 3, c.col 4, c.col 5) =
                      SELECT a.col 1
                                   a.col 2
                                   a.col 3
                                   a.col 4
                      FROM table1 a
                      WHERE a.col 1 = '123456');But how can I get also the correct data (col 9 and col 11) of table d?
What's missing in my where clause?
Hope this is a bit clear.
Regards,
Ken

Answer 1

Something like this:
CURSOR c_test IS
   SELECT a.col1,
          a.col13,
          a.col14,
          b.col6,
          b.col7,
          c.col8,
          c.col10,
          d.col9,
          d.col11
   FROM table1 a
   JOIN table2 b
   ON  a.col1 = b.col2
   AND a.col2 = b.col3
   AND a.col1 = '123456'
   JOIN table3 c
   ON  a.col3 = c.col4
   AND a.col4 = c.col5
   JOIN table4 d
   ON  a.col1 = d.col9;Check on a.col1 = d.col9, don't whether that's right.
