Kevin Liew updated PHOENIX-2476:
--------------------------------
Summary: Recognize '+' and CONCAT as string concatenation operators (was:
Recognize common string concatenation operator symbols)
> Recognize '+' and CONCAT as string concatenation operators
> ----------------------------------------------------------
>
> Key: PHOENIX-2476
> URL: https://issues.apache.org/jira/browse/PHOENIX-2476
> Project: Phoenix
> Issue Type: Improvement
> Affects Versions: 4.6.0
> Reporter: Kevin Liew
> Priority: Minor
> Labels: newbie, phoenix, string
>
> Phoenix uses '||' (Oracle, ANSII) as the string concatenation operator symbol
> and does not recognize '+'
> (SQL Server) or 'concat' (which is used for portability because it is
> supported by most databases)
> If we try to use '+' we get an error from the queryserver
> {noformat}Type mismatch. VARCHAR for (COLUMN1 + KEYCOLUMN){noformat}
> The '+'
> operator is not implemented for VARCHAR so it would be an improvement to
> implement the standard function for that '+' symbol
> If we try to use 'concat' we get an error:
> {noformat}org.apache.phoenix.schema.FunctionNotFoundException: ERROR 6001
> (42F01): Function undefined. functionName=[CONCAT]{noformat}
> 'concat' is often used for cross-database compatibility. Most databases
> provide this function
