Sql 通过单个参数的多个值

此查询显示此错误

Msg 241，16级，状态1，程序示例，第18行
从字符串转换日期和/或时间时，转换失败

---

然而，我尝试了替换和强制转换函数来解决这个问题，但没有找到解决方案，我将使用随附的

@params

来处理不需要连接到执行字符串的参数。我还建议对

@Department

进行更多的处理，以防止出现这种情况

SQL Server 2008中最好的方法是为

@DepartmentId

使用表值参数：

SQLZim的解决方案应该能起作用。但既然他没有提到这一点，我会指出错误的原因是这一行：

     (@BranchCode AS INT,
      @Department VARCHAR(8000),
      @DateFrom AS DATETIME,
      @DateTo AS DATETIME,

      -- @Delimiter char(1)
    )
AS
BEGIN
    SET NOCOUNT ON;

    DECLARE @Sql NVARCHAR(MAX), @Params nvarchar(8000);
    set @Params = '@BranchCode INT, @DateFrom DATETIME, @DateTo DATETIME, @TransactionNumber NVARCHAR(30)'

    SET @Sql = 'Select 
                    Mast.Branch_code, Mast.purerq_id as purerq_id,
                    Max(Mast.purreq_date) as purreq_date, Max(Mast.Dept_code) as Dept_code,

您需要将日期时间变量强制转换为nvarchar，并用单引号将其括起来。

-在ANSI-92 SQL标准（25年前）中，用正确的ANSI

JOIN

语法替换了旧样式的逗号分隔表样式，不鼓励使用该样式。谢谢您的指导，我的问题由你的向导解决了
