Question

我在原始查询（SQL Server）上使用分页，该查询对初始页面请求（第0页）起作用，但在我尝试获取第2页的结果时失败并且列名无效。生成的查询在SSMS中有效，但在Spring中不起作用。

感谢任何见解。

这是错误：

以下是模型：

@Entity
@Table(name = "vw_BdmProductInfo")  // A view!
public class BdmProductInfo {

@Id
private Long productKey;
private Long    materialKey;
private String  sku;
private BigDecimal  price;
private BigDecimal  listPrice;
private String  priceUom;
private String  casePack;
private String  packageSize;
private String  mfgItemNumber;
private String  productName;
private String  productDescription;
private String  mediaDomain;
private String  ImagePath;
private String  imageName;
private String searchText;

protected BdmProductInfo() {}

...

这是存储库：

@RestResource(path="findProductInfoByCategory")
@Query(value="SELECT p.ProductKey, p.ProductName, p.Sku, p.MaterialKey, p.MfgItemNumber, p.PackageSize, p.PriceUom, p.CasePack, p.ProductDescription, P.MediaDomain, p.ImagePath, p.ImageName, plp.Price, plp.ListPrice, p.SearchText  "
            + "FROM [dbo].[BdmProductCategory] pc "
            + "INNER JOIN [dbo].BdmProduct p on pc.ProductKey = p.productKey "
            + "INNER JOIN [dbo].BdmPriceListProduct plp on plp.ProductKey = p.ProductKey "
            + "WHERE pc.CategoryKey = :categoryKey "
            + "AND pc.ProductKey > 0 "
            + "AND pc.\"Delete\" = 0 "
            + "AND plp.PriceListKey = :priceListKey  \n-- #pageable\n ",
            countQuery="SELECT Count(*) "
            + "FROM [dbo].[BdmProductCategory] pc "
            + "INNER JOIN [dbo].BdmProduct p on pc.ProductKey = p.productKey "
            + "INNER JOIN [dbo].BdmPriceListProduct plp on plp.ProductKey = p.ProductKey "
            + "WHERE pc.categoryKey = :categoryKey "
            + "AND pc.ProductKey > 0 "
            + "AND pc.\"Delete\" = 0 "
            + "AND plp.PriceListKey = :priceListKey ",nativeQuery=true)
    Page<BdmProductInfo> findProductInfoByCategory(@Param("categoryKey") Long categoryKey, @Param("priceListKey") Long priceListKey, Pageable pageable );

Answer 1

在为查询列创建别名后，Hibernate使用了别名而不是试图生成自己的...导致问题。所以在查询中，为每个列选择了p.productKey as productKey等等别名......这样可以获得后续页面... FWIW 对于遇到这个问题的任何人......
