Simple groovy program which demonstrates a possible bug with groovy Sql.
Calling sql.rows(string) works while calling sql.rows(gstring) returns an empty result set.
This indicates a possible bug in the protected method groovy.sql.Sql.asSql().
The behavior is the same under groovy version 2.4.15, 2.5.2, 2.6.0-alpha-4, and 3.0.0-alpha-3 all running under OpenJDK Java 8.0.181-zulu.
Run this program by simply calling groovy sqlTest.groovy.
