> Try the following in SQL shell:
> {code}
> select '\\\\' like '%\\%';
> {code}
> It returned false, which is wrong.
> cc: [~yhuai] [~joshrosen]
> A false-negative considered previously:
> {code}
> select '\\\\' rlike '.*\\\\\\\\.*';
> {code}
> It returned true, which is correct if we assume that the pattern is treated as a Java
string but not raw string.
