> Run the following test in SqlOperatorTest:
> {code:java}
> f.checkString("REPLACE('ciao', '', 'ciao')", "ciao", "VARCHAR NOT NULL");
> {code}
> we will get "ciaocciaoiciaoaciaoociao", however the right result should be
> "ciao".
> Replace function should return unchanged string when search is an empty
> string ('').
> {code:java}
> REPLACE(string, search, replace)
> {code}
> I've tested this behavior in Oracle, PostgreSQL and SQL Server.
