这对你有帮助。:)按照下面的步骤，

Open the Query Editor Copy Paste the following code as it is, it will create the Function which converts the String to Int CREATE FUNCTION dbo.SplitInts ( @List VARCHAR(MAX), @Delimiter VARCHAR(255) ) RETURNS TABLE AS RETURN ( SELECT Item = CONVERT(INT, Item) FROM ( SELECT Item = x.i.value('(./text())[1]', 'varchar(max)') FROM ( SELECT [XML] = CONVERT(XML, '<i>' + REPLACE(@List, @Delimiter, '</i><i>') + '</i>').query('.') ) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y WHERE Item IS NOT NULL ); GO Create the Following stored procedure CREATE PROCEDURE dbo.sp_DeleteMultipleId @List VARCHAR(MAX) AS BEGIN SET NOCOUNT ON; DELETE FROM TableName WHERE Id IN( SELECT Id = Item FROM dbo.SplitInts(@List, ',')); END GO Execute this SP Using exec sp_DeleteId '1,2,3,12' this is a string of Id's which you want to delete, You can convert your array to string in C# and pass it as a Stored Procedure parameter as below, int[] intarray = { 1, 2, 3, 4, 5 }; string[] result = intarray.Select(x=>x.ToString()).ToArray();   SqlCommand command = new SqlCommand(); command.Connection = connection; command.CommandText = "sp_DeleteMultipleId"; command.CommandType = CommandType.StoredProcedure; command.Parameters.Add("@Id",SqlDbType.VARCHAR).Value=result ;

这将在单个存储的proc调用中删除多个行。愿一切都好！

Based on my experience, by creating a delimited expression from the employeeIDs, there is a tricky and nice solution for this problem. You should only create an string expression like ';123;434;365;' in-which 123, 434 and 365 are some employeeIDs. By calling the below procedure and passing this expression to it, you can fetch your desired records. Easily you can join the "another table" into this query. This solution is suitable in all versions of SQL server. Also, in comparison with using table variable or temp table, it is very faster and optimized solution.

CREATE PROCEDURE dbo.DoSomethingOnSomeEmployees  @List AS varchar(max)
AS
BEGIN
  SELECT EmployeeID 
  FROM EmployeesTable
  -- inner join AnotherTable on ...
  where @List like '%;'+cast(employeeID as varchar(20))+';%'
END
GO

从SQL Server 2016开始，你可以简单地使用分割字符串

例子:

WHERE (@LocationId IS NULL OR Id IN (SELECT items from Split_String(@LocationId, ',')))

我一直在搜索所有的例子和答案，如何传递任何数组到sql server，而不需要创建新的表类型的麻烦，直到我发现了这个链接，下面是我如何将它应用到我的项目:

——下面的代码将获取一个数组作为参数，并插入该数组的值 ——数组到另一个表

Create Procedure Proc1 


@UserId int, //just an Id param
@s nvarchar(max)  //this is the array your going to pass from C# code to your Sproc

AS

    declare @xml xml

    set @xml = N'<root><r>' + replace(@s,',','</r><r>') + '</r></root>'

    Insert into UserRole (UserID,RoleID)
    select 
       @UserId [UserId], t.value('.','varchar(max)') as [RoleId]


    from @xml.nodes('//root/r') as a(t)
END

如上所述，一种方法是将数组转换为字符串，然后在SQL Server中拆分字符串。

在SQL Server 2016，有一个内置的方法来分割字符串称为

STRING_SPLIT ()

它返回一组可以插入临时表(或实际表)的行。

DECLARE @str varchar(200)
SET @str = "123;456;789;246;22;33;44;55;66"
SELECT value FROM STRING_SPLIT(@str, ';')

会产生:

value
-----
  123
  456
  789
  246
   22
   33
   44
   55
   66

如果你想变得更花哨:

DECLARE @tt TABLE (
    thenumber int
)
DECLARE @str varchar(200)
SET @str = "123;456;789;246;22;33;44;55;66"

INSERT INTO @tt
SELECT value FROM STRING_SPLIT(@str, ';')

SELECT * FROM @tt
ORDER BY thenumber

会得到与上面相同的结果(除了列名是“number”)，但是排序了。您可以像使用其他表一样使用table变量，因此如果您愿意，可以轻松地将它与DB中的其他表连接起来。

请注意，您的SQL Server安装必须在兼容级别130或更高，以便STRING_SPLIT()函数被识别。您可以通过以下查询检查您的兼容性级别:

SELECT compatibility_level
FROM sys.databases WHERE name = 'yourdatabasename';

大多数语言(包括c#)都有一个“join”函数，可以用来从数组中创建字符串。

int[] myarray = {22, 33, 44};
string sqlparam = string.Join(";", myarray);

然后将sqlparam作为参数传递给上面的存储过程。

CREATE TYPE dumyTable
AS TABLE
(
  RateCodeId int,
  RateLowerRange int,
  RateHigherRange int,
  RateRangeValue int
);
GO
CREATE PROCEDURE spInsertRateRanges
  @dt AS dumyTable READONLY
AS
BEGIN
  SET NOCOUNT ON;

  INSERT  tblRateCodeRange(RateCodeId,RateLowerRange,RateHigherRange,RateRangeValue) 
  SELECT * 
  FROM @dt 
END
