Problem Statement
Running a native JPA query with a MySQL user variable containing ':' raises an exception due to an invalid Syntax: not allowed to follow ':' with a space.
Solution
To address this issue, you need to escape the ':' characters. This can be achieved by preceding them with a backslash '' character.
Here's the corrected query:
SELECT foo, bar, baz, @rownum:= if (@id = foo, @rownum+1, 1) as rownum, @id := foo as rep_id FROM foo_table ORDER BY foo, bar desc
Implementation in JPA
Query q = getEntityManager().createNativeQuery(query, SomeClass.class); return q.getResultList();
Note:
The solution provided assumes MySQL database. If using other databases, the syntax for escaping special characters may vary. Therefore, it's essential to refer to the specific database documentation for recommended escaping methods.
