我花了很长时间才弄明白，所以如果有人需要的话…

这是基于Aaron回答中的SQL 2005方法，并使用了他的SplitInts函数(我只是删除了delim参数，因为我总是使用逗号)。我正在使用SQL 2008，但我想要一些与类型化数据集(XSD, TableAdapters)一起工作的东西，我知道字符串参数与那些工作。

我试图让他的函数在“where in(1,2,3)”类型子句中工作，并没有直接的运气。所以我先创建了一个临时表，然后做了一个内部连接，而不是“在哪里”。下面是我的示例用法，在我的情况下，我想获得一个不包含某些成分的食谱列表:

CREATE PROCEDURE dbo.SOExample1
    (
    @excludeIngredientsString varchar(MAX) = ''
    )
AS
    /* Convert string to table of ints */
    DECLARE @excludeIngredients TABLE (ID int)
    insert into @excludeIngredients
    select ID = Item from dbo.SplitInts(@excludeIngredientsString)

    /* Select recipies that don't contain any ingredients in our excluded table */
   SELECT        r.Name, r.Slug
FROM            Recipes AS r LEFT OUTER JOIN
                         RecipeIngredients as ri inner join
                         @excludeIngredients as ei on ri.IngredientID = ei.ID
                         ON r.ID = ri.RecipeID
WHERE        (ri.RecipeID IS NULL)

上下文总是很重要的，比如数组的大小和复杂性。对于中小型榜单来说，这里列出的几个答案还不错，但有一些需要澄清的地方:

For splitting a delimited list, a SQLCLR-based splitter is the fastest. There are numerous examples around if you want to write your own, or you can just download the free SQL# library of CLR functions (which I wrote, but the String_Split function, and many others, are completely free). Splitting XML-based arrays can be fast, but you need to use attribute-based XML, not element-based XML (which is the only type shown in the answers here, though @AaronBertrand's XML example is the best as his code is using the text() XML function. For more info (i.e. performance analysis) on using XML to split lists, check out "Using XML to pass lists as parameters in SQL Server" by Phil Factor. Using TVPs is great (assuming you are using at least SQL Server 2008, or newer) as the data is streamed to the proc and shows up pre-parsed and strongly-typed as a table variable. HOWEVER, in most cases, storing all of the data in DataTable means duplicating the data in memory as it is copied from the original collection. Hence using the DataTable method of passing in TVPs does not work well for larger sets of data (i.e. does not scale well). XML, unlike simple delimited lists of Ints or Strings, can handle more than one-dimensional arrays, just like TVPs. But also just like the DataTable TVP method, XML does not scale well as it more than doubles the datasize in memory as it needs to additionally account for the overhead of the XML document.

说了这么多，如果你使用的数据很大，或者不是很大，但一直在增长，那么IEnumerable TVP方法是最好的选择，因为它将数据流传输到SQL Server(就像DataTable方法)，但不需要在内存中复制任何集合(不像任何其他方法)。我在这个回答中发布了一个SQL和c#代码的例子:

将字典传递给存储过程T-SQL

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

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
