意外标记：SELECT 靠近第 1 行，第 485 列
unexpected token: SELECT near line 1, column 485
我有这三个查询以及第一个和第二个查询 运行 正确，然后我使用这些查询形成第三个查询。
String CHECK_FOR_COMBOS1 = " SELECT new com.xxxx.domain.OpenCombo( productSub.id , CASE WHEN productClass.productClassIsProduction = 1 "
+ "THEN 0 ELSE 1 END ) FROM ProductSub productSub, Product product, ProductGroup productGroup,"
+ "ProductClass productClass "
+ " WHERE productSub.id = :productSubId"
+ " AND product.id = productSub.productId"
+ " AND productGroup.id = product.productGroupId"
+ " AND productClass.id = productGroup.productClassId";
String CHECK_FOR_COMBOS2 = "SELECT 1 FROM ProductSubProductSub productSubProductSub ,ProductSub productSub, Product product,"
+ "ProductGroup productGroup,ProductClass productClass "
+ " WHERE productSub.id = productSubProductSub.childProductSubId "

String CHECK_FOR_COMBOS3 = CHECK_FOR_COMBOS1 + " AND ( EXISTS " +CHECK_FOR_COMBOS2 + " ) GROUP BY productSub.id , "
+ " productClass.productClassIsProduction " ;
当我 运行 第三个查询时，出现以下错误。

它在 EXISTS 关键字后抱怨，我注意到它也在 Hibernate 中。谁能给我提示来解决这个问题？有没有比编写上述查询更好的处理方法？
首先，您错过了 exists 子句的 ()。另外，我不太确定您是否可以在 AND 条件下使用 EXISTS 子句。如果这在 SQL 上有效，您可以试试这个：
String CHECK_FOR_COMBOS3 = CHECK_FOR_COMBOS1 + " AND ( EXISTS (" +CHECK_FOR_COMBOS2 + ") ) GROUP BY productSub.id , "
+ " productClass.productClassIsProduction " ;
