Review Comment:
> it u only allow one predicate for one column. u should check it first. or
u should use multi map here. otherwise toMap will throw duplicate key
exception. btw, doris' column name is case insensitive, so u should use ci key
map.
Thanks for your comments. we support only one predicate for one column. so
i have added exception, and change map values to lowercase.
testcase:
mysql> SET enable_fallback_to_original_planner=false;
Query OK, 0 rows affected (0.01 sec)
mysql> show procedure status where Name ="TEST_PLSQL_SHOW_PROC1" and name
LIKE "TEST";
ERROR 1105 (HY000): errCode = 2, detailMessage = WhereClause can contain one
predicate for one column.
mysql> show procedure status where db ="TEST_PLSQL_SHOW_PROC1" and DB LIKE
"TEST";
ERROR 1105 (HY000): errCode = 2, detailMessage = WhereClause can contain one
predicate for one column.
