Solution 2

SQL

DECLARE @Output varchar(max) = ''
SELECT @Output = coalesce(@Output+',','') + CONVERT(varchar(max),Col1) FROM Table1
SET @Output = RIGHT(@Output,LEN(@Output)-1)
PRINT @Output

Correct, but this is more T-Sql way of doing. In MySQL, you can do it with GROUP_CONCAT function. See my answer.
Anyways, +5. :)

Thank You Bhardwaj with this query i am getting the comma seperated values when i execute the query through the query browser in mysql.But when i kept the same query in my code i am getting the exception as org.hibernate.MappingException: No Dialect mapping for JDBC type: -1. My code is like this

session = HibernateSessionFactory.getSession();

String hql = "select GROUP_CONCAT(SenderId) FROM userinfo";

senderIdValue = (String)session.createSQLQuery(hql).list().get(0);

Can you give me any idea about this exception.
