我收到并非所有命名参数都已设置的错误。下面是我的代码。
我的 SqlQuery 在 mysql 提示符下运行良好,您可以在问题SQL Query中引用架构
SELECT t.*
FROM (
SELECT @lim := 2,
@cg := ''
) vars,
(select * from Table1 order by product,amount, make) t
WHERE CASE WHEN @cg <> product THEN @r := @lim ELSE 1 END > 0
AND (@r := @r - 1) >= 0
AND (@cg := product) IS NOT NULL
ORDER BY
product,amount, make
我的java代码
try {
context.dbl.startTransaction();
Session session = context.dbl.getSession();
//String sqlQuery = "from com.infibeam.inventoryservice.dbObjects.PopularBrandDO";
String sqlQuery = "SELECT t.* ";
sqlQuery=sqlQuery + "FROM (";
sqlQuery=sqlQuery + "SELECT @lim := 2,";
sqlQuery=sqlQuery + "@cg := ''";
sqlQuery=sqlQuery + ") vars, ";
sqlQuery=sqlQuery + "(select * from Table1 order by product,amount, make) t";
sqlQuery=sqlQuery + " WHERE CASE WHEN @cg <> product THEN @r := @lim ELSE 1 END > 0";
sqlQuery=sqlQuery + " AND (@r := @r - 1) >= 0 ";
sqlQuery=sqlQuery + " AND (@cg := product) IS NOT NULL ";
sqlQuery=sqlQuery + " ORDER BY product,amount, make";
//Query query = session.createQuery(sqlQuery);
SQLQuery query = session.createSQLQuery(sqlQuery);
listItems = query.list();
}catch(RuntimeException e) {
e.printStackTrace();
}
下面是我得到的例外
org.hibernate.QueryException: Not all named parameters have been set: [] [SELECT t.* FROM (SELECT @lim := 2,@cg := '') vars, (select * from Table1 order by product,amount, make) t WHERE CASE WHEN @cg <> product THEN @r := @lim ELSE 1 END > 0 AND (@r := @r - 1) >= 0 AND (@cg := product) IS NOT NULL ORDER BY product,amount, make]
