tglanz opened a new issue, #18804:
URL: https://github.com/apache/datafusion/issues/18804

   ### Describe the bug
   
   During sort merge join, with a filter, and the columns count of the 
left/right relations are different, the extracted columns is off which leads to 
datafusion error such as:
   
   ```
   DataFusion error: Arrow error: Invalid argument error: number of columns(2) 
must match number of fields(4) in schema
   ```
   
   ### To Reproduce
   
   Following sqltests are failing
   
   ```
   statement ok
   set datafusion.optimizer.prefer_hash_join = false;
   
   statement ok
   DROP TABLE IF EXISTS t1;
   
   statement ok
   CREATE TABLE t1(a int, b int) AS VALUES (1, 100), (2, 200), (3, 300);
   
   statement ok
   DROP TABLE IF EXISTS t2;
   
   statement ok
   CREATE TABLE t2(a int, b int, c int) AS VALUES (4, 101, 1001), (3, 201, 
2001), (2, 250, 3001);
   
   statement ok
   DROP TABLE IF EXISTS t3;
   
   statement ok
   CREATE TABLE t3(x int) AS VALUES (1);
   
   query IIIII
   SELECT * FROM t2 RIGHT JOIN t1 on t1.a = t2.a AND t1.b < t2.b
   ----
   NULL NULL NULL 1 100
   2 250 3001 2 200
   NULL NULL NULL 3 300
   
   query IIIII
   SELECT * FROM t1 LEFT JOIN t2 on t1.a = t2.a AND t1.b < t2.b
   ----
   1 100 NULL NULL NULL
   2 200 2 250 3001
   3 300 NULL NULL NULL
   
   # Small table for LeftMark
   
   # LeftMark equijoin with different columns count
   query III rowsort
   SELECT t2.a, t2.b, t2.c
   FROM t2
   WHERE t2.a > 3 OR t2.a IN (SELECT t3.x FROM t3 WHERE t2.b < 150)
   ----
   4 101 1001
   ```
