Dynamic SQL Comma Delimited Value Query
Parameterized Queries with Like and In
I have a SQL Server Stored Procedure where I would like to pass a varchar full of comma delimited values to an IN function. For example:
DECLARE @Ids varchar(50);
SET @Ids = \'1,2,3,5,4,6,7,98,234\';
SELECT *
FROM sometable
WHERE tableid IN (@Ids);
This does not work of course. I get the error:
Conversion failed when converting the varchar value \'1,2,3,5,4,6,7,98,234\' to data type int.
How can I accomplish this (or something relatively similar) without resorting to building dynamic SQL?
回答1:
Don't use a function that loops to split a string!, my function below will split a string very fast, with no looping!
Before you use my function, you need to set up a "helper" table, you only need to do this one time per database:
CREATE TABLE Numbers
(Number int NOT NULL,
CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
DECLARE @x int
SET @x=0
WHILE @x<8000
BEGIN
SET @x=@x+1
INSERT INTO Numbers VALUES (@x)
END
use this function to split your string, which does not loop and is very fast:
CREATE FUNCTION [dbo].[FN_ListToTable]
(
@SplitOn char(1) --REQUIRED, the character to split the @List string on
,@List varchar(8000) --REQUIRED, the list to split apart
)
RETURNS
@ParsedList table
(
ListValue varchar(500)
)
AS
BEGIN
/**
Takes the given @List string and splits it apart based on the given @SplitOn character.
A table is returned, one row per split item, with a column name "ListValue".
This function workes for fixed or variable lenght items.
Empty and null items will not be included in the results set.
Returns a table, one row per item in the list, with a column name "ListValue"
EXAMPLE:
----------
SELECT * FROM dbo.FN_ListToTable(',','1,12,123,1234,54321,6,A,*,|||,,,,B')
returns:
ListValue
-----------
1
12
123
1234
54321
6
A
*
|||
B
(10 row(s) affected)
**/
----------------
--SINGLE QUERY-- --this will not return empty rows
----------------
INSERT INTO @ParsedList
(ListValue)
SELECT
ListValue
FROM (SELECT
LTRIM(RTRIM(SUBSTRING(List2, number+1, CHARINDEX(@SplitOn, List2, number+1)-number - 1))) AS ListValue
FROM (
SELECT @SplitOn + @List + @SplitOn AS List2
) AS dt
INNER JOIN Numbers n ON n.Number < LEN(dt.List2)
WHERE SUBSTRING(List2, number, 1) = @SplitOn
) dt2
WHERE ListValue IS NOT NULL AND ListValue!=''
RETURN
END --Function FN_ListToTable
you can use this function as a table in a join:
SELECT
Col1, COl2, Col3...
FROM YourTable
INNER JOIN FN_ListToTable(',',@YourString) s ON YourTable.ID = s.ListValue
Here is your example:
Select * from sometable where tableid in(SELECT ListValue FROM dbo.FN_ListToTable(',',@Ids) s)
回答2:
Of course if you're lazy like me, you could just do this:
Declare @Ids varchar(50) Set @Ids = ',1,2,3,5,4,6,7,98,234,'
Select * from sometable
where Charindex(','+cast(tableid as varchar(8000))+',', @Ids) > 0
回答3:
No Table No Function No Loop
Building on the idea of parsing your list into a table our DBA suggested using XML.
Declare @Ids varchar(50)
Set @Ids = ‘1,2,3,5,4,6,7,98,234’
DECLARE @XML XML
SET @XML = CAST('<i>' + REPLACE(@Ids, ',', '</i><i>') + '</i>' AS XML)
SELECT *
FROM
SomeTable
INNER JOIN @XML.nodes('i') x(i)
ON SomeTable .Id = x.i.value('.', 'VARCHAR(MAX)')
These seems to have the same performance as @KM's answer but, I think, a lot simpler.
回答4:
You can create a function that returns a table.
so your statement would be something like
select * from someable
join Splitfunction(@ids) as splits on sometable.id = splits.id
Here is a simular function.
CREATE FUNCTION [dbo].[FUNC_SplitOrderIDs]
(
@OrderList varchar(500)
)
RETURNS
@ParsedList table
(
OrderID int
)
AS
BEGIN
DECLARE @OrderID varchar(10), @Pos int
SET @OrderList = LTRIM(RTRIM(@OrderList))+ ','
SET @Pos = CHARINDEX(',', @OrderList, 1)
IF REPLACE(@OrderList, ',', '') <> ''
BEGIN
WHILE @Pos > 0
BEGIN
SET @OrderID = LTRIM(RTRIM(LEFT(@OrderList, @Pos - 1)))
IF @OrderID <> ''
BEGIN
INSERT INTO @ParsedList (OrderID)
VALUES (CAST(@OrderID AS int)) --Use Appropriate conversion
END
SET @OrderList = RIGHT(@OrderList, LEN(@OrderList) - @Pos)
SET @Pos = CHARINDEX(',', @OrderList, 1)
END
END
RETURN
END

It's a very common question. Canned answer, several nice techniques:

回答6:
This works perfectly! The below answers are too complicated. Don't look at this as dynamic. Set up your store procedure as follows:
(@id as varchar(50))
as
Declare @query as nvarchar(max)
set @query ='
select * from table
where id in('+@id+')'
EXECUTE sp_executesql @query
回答7:
Without using dynamic SQL, you have to take the input variable and use a split function to put the data into a temp table and then join to that.
回答8:
I can suggest using WITH like this:
DECLARE @Delim char(1) = ',';
SET @Ids = @Ids + @Delim;
WITH CTE(i, ls, id) AS (
SELECT 1, CHARINDEX(@Delim, @Ids, 1), SUBSTRING(@Ids, 1, CHARINDEX(@Delim, @Ids, 1) - 1)
UNION ALL
SELECT i + 1, CHARINDEX(@Delim, @Ids, ls + 1), SUBSTRING(@Ids, ls + 1, CHARINDEX(@Delim, @Ids, ls + 1) - CHARINDEX(@Delim, @Ids, ls) - 1)
FROM CTE
WHERE CHARINDEX(@Delim, @Ids, ls + 1) > 1
)
SELECT t.*
FROM yourTable t
INNER JOIN
CTE c
ON t.id = c.id;

Thanks, for your function I Used IT........................ This is my EXAMPLE
**UPDATE [RD].[PurchaseOrderHeader]
SET [DispatchCycleNumber] ='10'
WHERE OrderNumber in(select * FROM XA.fn_SplitOrderIDs(@InvoiceNumberList))**
CREATE FUNCTION [XA].[fn_SplitOrderIDs]
(
@OrderList varchar(500)
)
RETURNS
@ParsedList table
(
OrderID int
)
AS
BEGIN
DECLARE @OrderID varchar(10), @Pos int
SET @OrderList = LTRIM(RTRIM(@OrderList))+ ','
SET @Pos = CHARINDEX(',', @OrderList, 1)
IF REPLACE(@OrderList, ',', '') <> ''
BEGIN
WHILE @Pos > 0
BEGIN
SET @OrderID = LTRIM(RTRIM(LEFT(@OrderList, @Pos - 1)))
IF @OrderID <> ''
BEGIN
INSERT INTO @ParsedList (OrderID)
VALUES (CAST(@OrderID AS int)) --Use Appropriate conversion
END
SET @OrderList = RIGHT(@OrderList, LEN(@OrderList) - @Pos)
SET @Pos = CHARINDEX(',', @OrderList, 1)
END
END
RETURN
END

If you use SQL Server 2008 or higher, use table valued parameters; for example:
CREATE PROCEDURE [dbo].[GetAccounts](@accountIds nvarchar)
AS
BEGIN
SELECT *
FROM accountsTable
WHERE accountId IN (select * from @accountIds)
END
CREATE TYPE intListTableType AS TABLE (n int NOT NULL)
DECLARE @tvp intListTableType
-- inserts each id to one row in the tvp table
INSERT @tvp(n) VALUES (16509),(16685),(46173),(42925),(46167),(5511)
EXEC GetAccounts @tvp
回答11:
Create a table function like below which parse comma separated varchar and returns a table that can be inner joined with other tables.
CREATE FUNCTION [dbo].[fn_SplitList]
(
@inString varchar(MAX) = '',
@inDelimiter char(1) = ',' -- Keep the delimiter to 100 chars or less. Generally a delimiter will be 1-2 chars only.
)
RETURNS @tbl_Return table
(
Unit varchar(1000) COLLATE Latin1_General_BIN
)
AS
BEGIN
INSERT INTO @tbl_Return
SELECT DISTINCT
LTRIM(RTRIM(piece.value('./text()[1]', 'varchar(1000)'))) COLLATE DATABASE_DEFAULT AS Unit
FROM
(
--
-- Replace any delimiters in the string with the "X" tag.
--
SELECT
CAST(('<X>' + REPLACE(s0.prsString, s0.prsSplitDelimit, '</X><X>') + '</X>') AS xml).query('.') AS units
FROM
(
--
-- Convert the string and delimiter into XML.
--
SELECT
(SELECT @inString FOR XML PATH('')) AS prsString,
(SELECT @inDelimiter FOR XML PATH('')) AS prsSplitDelimit
) AS s0
) AS s1
CROSS APPLY units.nodes('X') x(piece)
RETURN
END
================================================= Now consume above created table function in your code,creation of function is one time activity in your database that can be used across databases as well on same server.
DECLARE @Ids varchar(50);
SET @Ids = '1,2,3,5,4,6,7,98,234';
SELECT
*
FROM sometable AS st
INNER JOIN fn_SplitList(@ids, ',') AS sl
ON sl.unit = st.tableid
回答12:
I think a very simple solution could be following:
DECLARE @Ids varchar(50);
SET @Ids = '1,2,3,5,4,6,7,98,234';
SELECT *
FROM sometable
WHERE ','+@Ids+',' LIKE '%,'+CONVERT(VARCHAR(50),tableid)+',%';

Its been a while but I have done this in the past using XML as a interim.
I can't take any credit for this, but I'm afraid I no longer know where I got this idea from:
-- declare the variables needed
DECLARE @xml as xml,@str as varchar(100),@delimiter as varchar(10)
-- The string you want to split
SET @str='A,B,C,D,E,Bert,Ernie,1,2,3,4,5'
-- What you want to split on. Can be a single character or a string
SET @delimiter =','
-- Convert it to an XML document
SET @xml = cast(('<X>'+replace(@str,@delimiter ,'</X><X>')+'</X>') as xml)
-- Select back from the XML
SELECT N.value('.', 'varchar(10)') as value FROM @xml.nodes('X') as T(N)

I have same idea with user KM. but do not need extra table Number. Just this function only.
CREATE FUNCTION [dbo].[FN_ListToTable]
(
@SplitOn char(1) --REQUIRED, the character to split the @List string on
,@List varchar(8000) --REQUIRED, the list to split apart
)
RETURNS
@ParsedList table
(
ListValue varchar(500)
)
AS
BEGIN
DECLARE @number int = 0
DECLARE @childString varchar(502) = ''
DECLARE @lengthChildString int = 0
DECLARE @processString varchar(502) = @SplitOn + @List + @SplitOn
WHILE @number < LEN(@processString)
BEGIN
SET @number = @number + 1
SET @lengthChildString = CHARINDEX(@SplitOn, @processString, @number + 1) - @number - 1
IF @lengthChildString > 0
BEGIN
SET @childString = LTRIM(RTRIM(SUBSTRING(@processString, @number + 1, @lengthChildString)))
IF @childString IS NOT NULL AND @childString != ''
BEGIN
INSERT INTO @ParsedList(ListValue) VALUES (@childString)
SET @number = @number + @lengthChildString - 1
END
END
END
RETURN
END
And here is the test:
SELECT ListValue FROM dbo.FN_ListToTable('/','a/////bb/c')
Result:

You could do it like this:
create or replace
PROCEDURE UDP_SETBOOKMARK
(
P_USERID IN VARCHAR2
, P_BOOKMARK IN VARCHAR2
) AS
BEGIN
UPDATE T_ER_Bewertung
SET LESEZEICHEN = P_BOOKMARK
WHERE STAMM_ID in( select regexp_substr(P_USERID,'[^,]+', 1, level) from dual
connect by regexp_substr(P_USERID, '[^,]+', 1, level) is not null )
and ER_ID = (select max(ER_ID) from T_ER_Bewertung_Kopie);
commit;
END UDP_SETBOOKMARK;
Then try it with
Begin
UDP_SETBOOKMARK ('1,2,3,4,5', 'Test');
End;
You can use this IN-Clause with regexp_substr in other situations too, just try it.
