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

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, ',')))

为存储过程使用表值参数。

当您从c#传递它时，您将添加数据类型为SqlDb.Structured的参数。

请看这里:http://msdn.microsoft.com/en-us/library/bb675163.aspx

例子:

// Assumes connection is an open SqlConnection object.
using (connection)
{
// Create a DataTable with the modified rows.
DataTable addedCategories =
  CategoriesDataTable.GetChanges(DataRowState.Added);

// Configure the SqlCommand and SqlParameter.
SqlCommand insertCommand = new SqlCommand(
    "usp_InsertCategories", connection);
insertCommand.CommandType = CommandType.StoredProcedure;
SqlParameter tvpParam = insertCommand.Parameters.AddWithValue(
    "@tvpNewCategories", addedCategories);
tvpParam.SqlDbType = SqlDbType.Structured;

// Execute the command.
insertCommand.ExecuteNonQuery();
}

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 ))

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
