> Key: IGNITE-18964
> URL: https://issues.apache.org/jira/browse/IGNITE-18964
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Affects Versions: 2.14
> Reporter: Chenjian
> Assignee: Chenjian
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> It's a capture corner case for the IGNITE-12687.
> The current `SqlListenerUtils.translateSqlWildcardsToRegex` not handle
> consecutive "_" character correctly.
> eg:
> {code:java}
> If we have a escaped table name a\\_\\_b_c should be translated to a__b_c not
> a\\__b_c{code}
>
> Without the fix, user can not get their tables search by escaped table names
> if they created table with more than one consecutive "_"
> Affected version is from 2.9 to 2.14
