Milosz Tylenda commented on OPENJPA-232:
----------------------------------------
Hi Julien, I am afraid this issue might not be a duplicate of OPENJPA-920,
rather a related one only. Although the 2nd parameter to LIKE might give an
error similar to OPENJPA-920, the stack trace indicates that this is rather the
1st parameter which blows OpenJPA up (the nested CONCATs).

> Affects Versions: 0.9.7
> Environment: Using H2 as the target SQL dialect.
> Reporter: Dan Everton

> I'm attempting to do a case insensitive search for a substring within the
> concatenation of two columns. The EJB QL I came up with looks like this:
> where lower(concat(concat(e.firstname, ' '), e.surname))) like
> concat(lower(:name), '%')
> however trying to execute that results in the following parse exception.
> Caused by: <0.0.0 nonfatal user error>
> org.apache.openjpa.persistence.ArgumentException: Encountered "lower ( concat
> ( concat ( e . firstname , \' \' ) , e . surname ) ) )" at character 32, but
> expected: ["(", ")", "+", ",", "-", ".", ":", "<", "<=", "<>", "=", ">",
> ">=", "?", "ABS", "ALL", "AND", "ANY", "AS", "ASC", "AVG", "BETWEEN", "BOTH",
