> While working on a Drill plugin, Calcite unparsed a *JdbcRel* node and produced the following PostgreSQL query
> {code:sql}
> SELECT "TEMP( Test)( 535799381)( 0)"
> FROM (SELECT "STRPOS"("str1", 'BI') = 1 AS "TEMP( Test)( 535799381)( 0)"
> FROM "TestV1"."Calcs") AS "t"
> GROUP BY "TEMP( Test)( 535799381)( 0)"
> {code}
> The query fails due to a parsing exception, the reason is that the *STRPOS* function name is quoted using double quotes. I tried the query manually without quoting the function name and it executed successfully.
> I debugged through Calcite and found that the [this method|https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/sql/SqlUtil.java#L262] unparses the function name as a plain identifier which leads to the [quoting of the function name|https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/sql/SqlIdentifier.java?deDup474625=1#L287] if the dialect supports it.
> Drill uses Calcite v1.4 but as I compared it with the master branch, I found them identical.
> I haven't tried that with custom functions yet.
