T-SQL查询中的休眠数据异常（Java Web应用程序）

Question

I have problem with executing the following T-SQL script in Java application using hibernate sessionFactory, however, this SQL code works when I run it in PostgreSQL:

...
query = session.createSQLQuery(
        "; CREATE TEMP TABLE deathuntil1 AS "+
        "     SELECT id, jamoatorgunit, organisationunitid "+
        "       , REGEXP_REPLACE( "+
        "               COALESCE( "+
        "                   substring( "+
        "                       CAST(age(deathdate,birthdate) AS character varying ) "+ 
        "                       from 1 for "+
        "                           CASE WHEN (position('years' in CAST(age(deathdate,birthdate) AS character varying ))-1)>0 THEN position('years' in CAST(age(deathdate,birthdate) AS character varying ))-1 ELSE 0 END "+
        "                       ) "+
        "               , '0'), '[^0-9]*' ,'0')::integer AS years "+
        "     FROM public.cro_death "+ 
        "     WHERE "+ 
        "       length(firstname)>= 3 "+ 

        ";" 
    );

query.executeUpdate();

the following is the error from Eclipse console:

Answer 1

When running this sql through java, there is a "misunderstanding" of :: casting.

Please replace '[^0-9]*' ,'0')::integer with '[^0-9]*' ,'0')\\\\:\\\\:integer and it should work.
