Re: JDBC4 with SQLXML and postgresql-8.4-702.jdbc4.jar - Mailing list pgsql-jdbc

Thanks,

sorry for my poor level in Java/JDBC :

but how do you use that ?

i've tried :

ret.updateObject("DATA",writer.toString() ,java.sql.Types.SQLXML);

but it's still doesn't work :

ERROR: column "DATA" is of type xml but expression is of type character varying
  Hint: You will need to rewrite or cast the expression.

neither this one :

ret.updateObject("DATA",(java.sql.Types.SQLXML)writer.toString());


sorry,

i've tried to convert my xml into String but it still doesn't work :

the error appear when i did a updaterow in my resultset


the error is:

org.postgresql.util.PSQLException: ERROR: column "DATA" is of type xml
but expression is of type character varying

It's one of those irritating areas where PostgreSQL's overzealous refusal to cast ::text or ::varchar for interpretation as literals of another type bites you.

You need to use updateObject("DATA", java.sql.Types.SQLXML) so the JDBC driver knows what type to specify.
