@Retired_mod , thanks for the detailed suggestions.
1. Running SHOW COLUMN STATS yields the following error:
[PARSE_SYNTAX_ERROR] Syntax error at or near 'CHECK'. SQLSTATE: 42601 line 1, pos 0
== SQL ==
CHECK COLUMN STATS <catalog>.<schema>.<table>
^^^
Ran DESCRIBE DETAIL <catalog>.<schema>.<table> successfully, and it indicates no column stats are currently being collected.
3. Ran ANALYZE TABLE <catalog>.<schema>.<table> COMPUTE STATISTICS FOR COLUMN my_col_1; for a single column, and faced the same error.
Any further troubleshooting tips are much appreciated!
