问题
I have written an application using Seam 2.2.1 & MySQL which is working. I am now trying to connect the application to Informix and when I execute a query from hibernate(select user from User user) I am getting the following exceptions:
org.hibernate.exception.genericjdbcexception could not execute query
when i execute a query as select user.id,user.name from User user it's executed successefuly.
The Generated sql is
select first 2 user0_.USER_ID as USER1_120_, user0_.dateOfBirth as dateOfBi2_120_, user0_.enabled as enabled120_, user0_.forename as forename120_, user0_.password as password120_, user0_.surname as surname120_, user0_.userName as userName120_ from anetidb.user user0_ where username=?
The Stacktrace of exception:
12:00:24,407 INFO [IntegerType] could not read column value from result set: USER1_120_; No such column name 12:00:24,665 WARN [JDBCExceptionReporter] SQL Error: -79738, SQLState: IX000 12:00:24,873 ERROR [JDBCExceptionReporter] No such column name
And i Use org.hibernate.dialect.InformixDialect as hibernate.dialect
Have you an idea about the problem?
Thks For Help.
回答1:
Googling for "No such column name" informix hibernate has led me to the following Hibernate bug report, which describes exactly the same problem: https://hibernate.onjira.com/browse/HBX-1126
The solution seems to remove the parameter DELIMIDENT=y from the datasource URL.

You meant this query:
FROM User
Because the select tag in HQL doesn't have to be specified when you want to retrieve all the properties of the object.
