@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!
