concat function in EJB QL doesn't nest
--------------------------------------
Key: OPENJPA-232
URL: https://issues.apache.org/jira/browse/OPENJPA-232
Project: OpenJPA
Issue Type: Bug
Components: jpa
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", "BY",
"CONCAT", "COUNT", "CURRENT_DATE", "CURRENT_TIME", "CURRENT_TIMESTAMP",
"DELETE", "DESC", "DISTINCT", "EMPTY", "ESCAPE", "EXISTS", "FETCH", "FROM",
"GROUP", "HAVING", "IN", "INNER", "IS", "JOIN", "LEADING", "LEFT", "LENGTH",
"LIKE", "LOCATE", "LOWER", "MAX", "MEMBER", "MIN", "MOD", "NEW", "NOT", "NULL",
"OBJECT", "OF", "OR", "ORDER", "OUTER", "SELECT", "SET", "SIZE", "SOME",
"SQRT", "SUBSTRING", "SUM", "TRAILING", "TRIM", "UPDATE", "UPPER", "WHERE",
