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 

希望大家喜欢

您需要将其作为XML参数传递。

编辑:快速代码从我的项目给你一个想法:

CREATE PROCEDURE [dbo].[GetArrivalsReport]
    @DateTimeFrom AS DATETIME,
    @DateTimeTo AS DATETIME,
    @HostIds AS XML(xsdArrayOfULong)
AS
BEGIN
    DECLARE @hosts TABLE (HostId BIGINT)

    INSERT INTO @hosts
        SELECT arrayOfUlong.HostId.value('.','bigint') data
        FROM @HostIds.nodes('/arrayOfUlong/u') as arrayOfUlong(HostId)

然后您可以使用临时表来连接您的表。 我们将arrayOfUlong定义为一个内置的XML模式，以维护数据完整性，但您不必这样做。我建议使用它，这里有一个快速代码，以确保您总是得到一个带long的XML。

IF NOT EXISTS (SELECT * FROM sys.xml_schema_collections WHERE name = 'xsdArrayOfULong')
BEGIN
    CREATE XML SCHEMA COLLECTION [dbo].[xsdArrayOfULong]
    AS N'<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="arrayOfUlong">
        <xs:complexType>
            <xs:sequence>
                <xs:element maxOccurs="unbounded"
                            name="u"
                            type="xs:unsignedLong" />
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>';
END
GO

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！

从SQL Server 2016开始，您可以将列表作为NVARCHAR()并使用OPENJSON

DECLARE @EmployeeList nvarchar(500) = '[1,2,15]'


SELECT * 
FROM Employees
WHERE ID IN (SELECT VALUE FROM OPENJSON(@EmployeeList ))

在sql server中不支持array，但是有几种方法可以将collection传递给存储的proc。

通过使用数据表 通过使用XML。尝试将您的集合转换为xml格式，然后将其作为输入传递给存储过程

将集合传递给存储过程

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
