Multiple Selects and a Join ..SQL Oracle

Question

SELECT table1.col1, table2.col2
FROM table1
WHERE col3
IN(SELECT col1 FROM table3 WHERE col4 IN(SELECT col4 FROM table4 WHERE col5 LIKE '%XYZ%'))
INNER JOIN table2 ON table1.col1=table2.col6
ORDER BY table1.col1

I get a ORA00933 error.SQL command not properly ended. If I remove the join, the query works perfectly. But i need the join. The error is near the LIKE keyword. How can I solve it?

Answer 1

You have misplaced the INNER JOIN , it was located in your WHERE clause.

Note that you might want to adopt some formatting scheme for writing SQL Statements. It makes it much easier to spot these kind of errors.

SELECT table1.col1, table2.col2 
FROM   table1 
       INNER JOIN table2 ON table1.col1=table2.col6 
WHERE  col3 IN (
          SELECT col1 
          FROM table3 
          WHERE col4 IN (
             SELECT col4 
             FROM table4 
             WHERE col5 LIKE '%XYZ%'
          )
       ) 
ORDER BY table1.col1

Answer 2

Try moving your join up ahead of your WHERE clause:

    SELECT table1.col1, table2.col2
    FROM table1
    INNER JOIN table2 ON table1.col1=table2.col6
    WHERE col3
    IN(SELECT col1 FROM table3 WHERE col4 IN(SELECT col4 FROM table4 WHERE col5 LIKE '%XYZ%'))
    ORDER BY table1.col1
