>                 Key: IGNITE-17055
>                 URL: https://issues.apache.org/jira/browse/IGNITE-17055
>             Project: Ignite
>          Issue Type: Bug
>            Reporter: Mikhail Pochatkin
>            Assignee: Mikhail Pochatkin
>            Priority: Major
>              Labels: ignite-3, jdbc
>          Time Spent: 20m
>  Remaining Estimate: 0h
>
> Currently in org.apache.ignite.internal.jdbc.JdbcStatement#execute0 exist async call to org.apache.ignite.internal.jdbc.proto.JdbcQueryEventHandler
>  
> {code:java}
> protected void execute0(JdbcStatementType stmtType, String sql, List<Object> args) throws SQLException {
>     ...
>     
>     res = conn.handler().queryAsync(req).join();
>    
>     ...
> } {code}
> Main problem with this part of code is that in case when the handler cannot parse SQL qeury will throw 
> {code:java}
> java.util.concurrent.CompletionException: class org.apache.ignite.client.IgniteClientException: Failed to parse query{code}
>  without any catching. This is doesn't match with Jdbc contract in the section of possible exeptions and looks like unpredictable behavior.
