Urgency: Normal

> Issue a clearer syntax error message for use of LIKE with a numeric column
> --------------------------------------------------------------------------
>
> Key: DERBY-6020
> URL: https://issues.apache.org/jira/browse/DERBY-6020
> Project: Derby
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 10.9.1.0
> Reporter: Bryan Pendleton
> Labels: derby_triage10_11
>
> I tried to use 'LIKE' with a numeric column, and the message was quite confusing:
> ij version 10.9
> ij> connect 'jdbc:derby:brydb;create=true';
> WARNING 01J01: Database 'brydb' not created, connection made to existing database instead.
> ij> drop table bry;
> 0 rows inserted/updated/deleted
> ij> CREATE TABLE bry( col1 varchar(10), JOBNUMBER INTEGER default 0);
> 0 rows inserted/updated/deleted
> ij> select * from bry where col1 like '%' or JobNumber like '%';
> ERROR 42884: No authorized routine named 'LIKE' of type 'FUNCTION' having compatible arguments was found.
> ij> quit;
> It would have been much easier to diagnose my problem if the message had said something like:
> ERROR xxxxx: Operator 'LIKE' must be used with a character expression, but argument 'JobNumber' is of type 'INTEGER'
