Subject Re: How to do when i want to query like "select * from book where book.name like 'TCP' "?
Date Wed, 30 Jul 2003 18:33:28 GMT
I think I find  a bug.
I used the torque 3.0.2.
when I used the second method ,but the result of query is wrong.
I open the log4j in debug mode.
I find the SQL query is wrong .
code:
   Criteria crit2 = new Criteria();
   crit2.add("BOOK.TITLE", (Object)"TCP", Criteria.LIKE);
   
   List results = BookPeer.doSelect(crit2);
   printBooklist(results);
The log4j is like this.
DEBUG [main] util.BasePeer (createQueryString:994) - SELECT book.BOOK_ID, book.TITLE, book.ISBN,
book.TIME, book.PUBLISHER_ID, book.AUTHOR_ID FROM book, BOOK WHERE BOOK.TITLE = 'TCP'
DEBUG [main] util.BasePeer (executeQuery:1532) - Elapsed time=0 ms

Cast the second method parameter to an Object:
crit1.add(BookPeer.TITLE, (Object)"TCP", Criteria.LIKE);

The problem is that there is another Criteria.add() method that takes a
String as the second parameter, but this String represents the column name
and not its' value.  See the Criteria javadocs.

Best of luck!
Tom

I has used method which is like that you say.
but there is error in compileing this line when i work at eclipse.
code :
   Criteria crit1 = new Criteria();
   crit1.add(BookPeer.TITLE, "TCP", Criteria.LIKE);
   List results = BookPeer.doSelect(crit1);

java.lang.Error: 无法解析的编译问题:
 方法 add(String, Object, SqlEnum)对于类型 Criteria 有歧义

 at com.kazmier.BookStore.main(BookStore.java:76)
Exception in thread "main"
