It doesn't panic when the source table exists.

cat /tmp/a.csv

3,4
5,6

❯ create external table a(x int, y int) stored as csv location '/tmp/a.csv';
0 rows in set. Query took 0.031 seconds.

+------------+
| COUNT(a.x) |
+------------+
| 3          |
+------------+
1 row in set. Query took 0.041 seconds.
