How to escape colon `:` within a native SQL query in Hibernate?

Question

I have a native SQL query that looks like that :

Query query = session.createSQLQuery(\"SELECT
        XMLSERIALIZE
        (CONTENT
          XMLELEMENT
           


        

Answer 1

In Hibernate, escaping is done with prepending by \. But in Java, you also have to escape \ by another \. So every : needs to be replaced by \\:. Finally, you get:

Query query = session.createSQLQuery("SELECT
    XMLSERIALIZE
    (CONTENT
      XMLELEMENT
      (
        NAME \"ltc\\:DOAATLTC\",
        XMLATTRIBUTES
        (
          'http://www.edftrading.com/Trade/Common/DoaatLTC' AS \"xmlns\\:ltc\",
          'http://www.edftrading.com/Trade/Common/DoaatLTCHourlyNomination' AS \"xmlns\\:ltchnom\"
        ),
        XMLELEMENT ( ... ) FROM ...");

Answer 2

If your colon is a cast like SELECT reltuples::BIGINT then you can rewrite it as a cast(reltuples as BIGINT) to avoid the colons.
