Question

我将所有sql查询转换为使用Hibernate参数。现在，当我在查询中添加一个参数并用变量映射它时，它总是给我错误：

错误o.h.e.jdbc.spi.SqlExceptionHelper - 转换数据类型时出错 nvarchar到bigint。

它没有任何意义，因为我添加了一个字符串参数。

查询如下：

Query query = session.createSQLQuery("SELECT Sum([qtyrequired]) as pcs, o.materialrequireddate, itemid  "
                + "FROM   [materialManagement].[pcsorderrequirement] r  JOIN materialmanagement.pcsorders o  "
                + "ON o.id = r.pcsorderid  WHERE  itemid IN ( :items )   "
                + "AND Cast(o.materialrequireddate AS DATE) >= Cast(Getdate() AS DATE)  "
                + "AND o.materialrequireddate <= Cast( :endDate AS DATE)  "
                + "GROUP  BY o.materialrequireddate, itemid")
                .setString("items", items).setString("endDate", endDate.format(DateTimeFormatter.ISO_LOCAL_DATE));

当我返回原始工作查询时，它看起来像：

Query query = session.createSQLQuery("SELECT Sum([qtyrequired]) as pcs, o.materialrequireddate, itemid  "
                + "FROM   [materialManagement].[pcsorderrequirement] r  " + "JOIN materialmanagement.pcsorders o  "
                + "ON o.id = r.pcsorderid  " + "WHERE  itemid IN (" + items + ")   "
                + "AND Cast(o.materialrequireddate AS DATE) >= Cast(Getdate() AS DATE)  "
                + "AND o.materialrequireddate <= Cast('" + endDate + "' AS DATE)  "
                + "GROUP  BY o.materialrequireddate, itemid");

使用命名参数时可以创建此异常的内容是什么？我使用的是Hibernate 5.1和数据库MS SQL服务器。

我将查询更改为不转换为日期，并使用正确的类型设置参数：

Query query = session.createSQLQuery("SELECT Sum([qtyrequired]) as pcs, o.materialrequireddate, itemid  "
                + "FROM   [materialManagement].[pcsorderrequirement] r  JOIN materialmanagement.pcsorders o "
                + "ON o.id = r.pcsorderid  WHERE  itemid IN ( :items ) "
                + "AND Cast(o.materialrequireddate AS DATE) >= Cast(Getdate() AS DATE)  "
                + "AND o.materialrequireddate <= :endDate "
                + "GROUP  BY o.materialrequireddate, itemid").setParameterList("items", items.stream().map(Item::getId).collect(Collectors.toList()))
                .setDate("endDate", Date.from(endDate.atStartOfDay(ZoneId.systemDefault()).toInstant()));
