My requirement is to send Columnname as Parameter to Stored procedure and do SUM on that Column.
I have written a small stored procedure to accept the column name as a parameter and do sum on that but I am getting an error with it.
CREATE PROCEDURE dbo.testCol
-- Add the parameters for the stored procedure here
#type as nvarchar(20),
#beginDate as smalldatetime,
#endDate as smalldatetime
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
select dbo.mytable.date, sum(#type) as quantity
from dbo.mytable
where dbo.mytable.Date between #beginDate AND #endDate
group by dbo.mytable.date,dbo.mytable.day
order by dbo.mytable.date
END
GO
I am getting the error as "Operand data type nvarchar is invalid for sum operator." while executing this stored procedure.
Any help much appreciated.
Thanks
You'll need to use dynamic sql to get the passed column name to be used this way in the query.
Use sp_executesql and include the column name in the string, and pass #beginDate and #endDate as parameters.
If you know the column names that are valid values, you can use CASE to avoid the evils of SQL Injection:
select dbo.mytable.date,
sum(case #type when 'QuantityColumn1' then QuantityColumn1
else QuantityColumn2 end ) as quantity
from dbo.mytable
where dbo.mytable.Date between #beginDate AND #endDate
group by dbo.mytable.date,dbo.mytable.day
order by dbo.mytable.date
If you must resort to dynamic SQL, validate your input so it can be trusted.
Yes, there is an easier way, Coolcake. Just cast the variable first like so:
CREATE TABLE FOO
(N VARCHAR(20))
SELECT * FROM DBO.FOO
INSERT INTO FOO VALUES('10')
INSERT INTO FOO VALUES('20')
INSERT INTO FOO VALUES('30')
INSERT INTO FOO VALUES('40')
INSERT INTO FOO VALUES('50')
SELECT SUM(CAST(N AS INT)) FROM FOO

I have a select query that returns a dataset with "n" records in one column. I would like to use this column as the parameter in a stored procedure. Below a reduced example of my case.
The query:
SELECT code FROM rawproducts
The dataset:
CODE
1
2
3
The stored procedure:
ALTER PROCEDURE [dbo].[MyInsertSP]
(#code INT)
AS
BEGIN
INSERT INTO PRODUCTS description, price, stock
SELECT description, price, stock
FROM INVENTORY I
WHERE I.icode = #code
END
I already have the actual query and stored procedure done; I just am not sure how to put them both together.
I would appreciate any assistance here! Thank you!
PS: of course the stored procedure is not as simple as above. I just choose to use a very silly example to keep things small here. :)
Here's two methods for you, one using a loop without a cursor:
DECLARE #code_list TABLE (code INT);
INSERT INTO #code_list SELECT code, ROW_NUMBER() OVER (ORDER BY code) AS row_id FROM rawproducts;
DECLARE #count INT;
SELECT #count = COUNT(*) FROM #code_list;
WHILE #count > 0
BEGIN
DECLARE #code INT;
SELECT #code = code FROM #code_list WHERE row_id = #count;
EXEC MyInsertSP #code;
DELETE FROM #code_list WHERE row_id = #count;
SELECT #count = COUNT(*) FROM #code_list;
END;
This works by putting the codes into a table variable, and assigning a number from 1..n to each row. Then we loop through them, one at a time, deleting them as they are processed, until there is nothing left in the table variable.
But here's what I would consider a better method:
CREATE TYPE dbo.code_list AS TABLE (code INT);
GO
CREATE PROCEDURE MyInsertSP (
#code_list dbo.code_list)
AS
BEGIN
INSERT INTO PRODUCTS (
[description],
price,
stock)
SELECT
i.[description],
i.price,
i.stock
FROM
INVENTORY i
INNER JOIN #code_list cl ON cl.code = i.code;
END;
GO
DECLARE #code_list dbo.code_list;
INSERT INTO #code_list SELECT code FROM rawproducts;
EXEC MyInsertSP #code_list = #code_list;
To get this to work I create a user-defined table type, then use this to pass a list of codes into the stored procedure. It means slightly rewriting your stored procedure, but the actual code to do the work is much smaller.
(how to) Run a stored procedure using select columns as input
parameters?
What you are looking for is APPLY; APPLY is how you use columns as input parameters. The only thing unclear is how/where the input column is populated. Let's start with sample data:
IF OBJECT_ID('dbo.Products', 'U') IS NOT NULL DROP TABLE dbo.Products;
IF OBJECT_ID('dbo.Inventory','U') IS NOT NULL DROP TABLE dbo.Inventory;
IF OBJECT_ID('dbo.Code','U') IS NOT NULL DROP TABLE dbo.Code;
CREATE TABLE dbo.Products
(
[description] VARCHAR(1000) NULL,
price DECIMAL(10,2) NOT NULL,
stock INT NOT NULL
);
CREATE TABLE dbo.Inventory
(
icode INT NOT NULL,
[description] VARCHAR(1000) NULL,
price DECIMAL(10,2) NOT NULL,
stock INT NOT NULL
);
CREATE TABLE dbo.Code(icode INT NOT NULL);
INSERT dbo.Inventory
VALUES (10,'',20.10,3),(11,'',40.10,3),(11,'',25.23,3),(11,'',55.23,3),(12,'',50.23,3),
(15,'',33.10,3),(15,'',19.16,5),(18,'',75.00,3),(21,'',88.00,3),(21,'',100.99,3);
CREATE CLUSTERED INDEX uq_inventory ON dbo.Inventory(icode);
The function:
CREATE FUNCTION dbo.fnInventory(#code INT)
RETURNS TABLE AS RETURN
SELECT i.[description], i.price, i.stock
FROM dbo.Inventory I
WHERE I.icode = #code;
USE:
DECLARE #code TABLE (icode INT);
INSERT #code VALUES (10),(11);
SELECT f.[description], f.price, f.stock
FROM #code AS c
CROSS APPLY dbo.fnInventory(c.icode) AS f;
Results:
description price stock
-------------- -------- -----------
20.10 3
40.10 3
Updated Proc (note my comments):
ALTER PROC dbo.MyInsertSP -- (1) Lose the input param
AS
-- (2) Code that populates the "code" table
INSERT dbo.Code VALUES (10),(11);
-- (3) Use CROSS APPLY to pass the values from dbo.code to your function
INSERT dbo.Products ([description], price, stock)
SELECT f.[description], f.price, f.stock
FROM dbo.code AS c
CROSS APPLY dbo.fnInventory(c.icode) AS f;
This ^^^ is how it's done.
I want to create a procedure in which I insert data into several tables. I need to get the inserted ID's so I create temp table in which I catch them. The problem is that I receive an error "Invalid column name 'app_guid'" and "Invalid column name 'app_nazwa_pliku'" but I create temp tables with such columns. Do you happen to know what's wrong with my code?

SQL Server compiles the procedure at creation and when it is first executed, verifying the entire procedure based on the context at that time.
For example, try the following query:
CREATE PROCEDURE P
AS
IF OBJECT_ID('tempdb..#T') IS NOT NULL DROP TABLE #T
SELECT 1 Y INTO #T
SELECT Y FROM #T
GO
CREATE TABLE #T (X INT)
GO
EXEC P
You will get an error ("Invalid column name 'Y'."), because when the procedure is compiled the table #T has only the column X.
To avoid this problem, you should make sure that the table #T either does not exist or has the right columns, before the procedure is executed.
One way would be to have another stored procedure (a wrapper):
CREATE PROCEDURE P1
AS
SELECT 1 Y INTO #T
SELECT Y FROM #T
GO
CREATE PROCEDURE P2
AS
IF OBJECT_ID('tempdb..#T') IS NOT NULL DROP TABLE #T
EXEC P1
GO
CREATE TABLE #T (X INT)
GO
EXEC P2
GO
DROP PROCEDURE P1, P2
--DROP TABLE #T
Another way would be to use dynamic SQL, because that code is compiled separately, as if it would be another stored procedure.
A better way would be to make sure that temp tables are uniquely named in each stored procedure, unless sharing data between them is desired. For the later case, you can read http://www.sommarskog.se/share_data.html#temptables for more insights.
This error is also encountered when a stored procedure creates a #temp table and then fires a trigger which creates a #temp table with the same name. The SP #temp table is referenced by the trigger when the column names are explicit, (like SELECT id FROM #temp;), but the local trigger #temp table is referenced when SELECT * FROM #temp; is used.
Microsoft, if you are listening, could you kindly attend to it and retrofit existing supported versions with a maintenance update?
The end result of what I am after is a query that calls a function and that function returns a set of records that are in their own separate fields. I can do this but the results of the function are all in one field.
ie: http://i.stack.imgur.com/ETLCL.png and the results I am after are: http://i.stack.imgur.com/wqRQ9.png
Here's the code to create the table
CREATE TABLE tbl_1_hm
(
tbl_1_hm_id bigserial NOT NULL,
tbl_1_hm_f1 VARCHAR (250),
tbl_1_hm_f2 INTEGER,
CONSTRAINT tbl_1_hm PRIMARY KEY (tbl_1_hm_id)
)
-- do that for a few times to get some data
INSERT INTO tbl_1_hm (tbl_1_hm_f1, tbl_1_hm_f2)
VALUES ('hello', 1);
CREATE OR REPLACE FUNCTION proc_1_hm(id BIGINT)
RETURNS TABLE(tbl_1_hm_f1 VARCHAR (250), tbl_1_hm_f2 int AS $$
SELECT tbl_1_hm_f1, tbl_1_hm_f2
FROM tbl_1_hm
WHERE tbl_1_hm_id = id
$$ LANGUAGE SQL;
--And here is the current query I am running for my results:
SELECT t1.tbl_1_hm_id, proc_1_hm(t1.tbl_1_hm_id) AS t3
FROM tbl_1_hm AS t1
Thanks for having a read. Please if you want to haggle about the semantics of what I am doing by hitting the same table twice or my naming convention --> this is a simplified test.
When a function returns a set of records, you should treat it as a table source:
SELECT t1.tbl_1_hm_id, t3.*
FROM tbl_1_hm AS t1, proc_1_hm(t1.tbl_1_hm_id) AS t3;
Note that functions are implicitly using a LATERAL join (scroll down to sub-sections 4 and 5) so you can use fields from tables listed previously without having to specify an explicit JOIN condition.
I want to use a variable inside IN clause, similar to this:

How can I use variable in IN clause using the first approach?
You will have to insert the values into a temp table.
Something like
DECLARE #TempTable TABLE(
assessmentId VARCHAR(50)
)
INSERT INTO #TempTable
VALUES
('02ea2b81-07f0-4660-bca1-81563f65bf65'),
('07728975-cb1d-484c-8894-14f5b793cbef'),
('1071ee4f-a214-443f-8694-0b3e9d2dc77e'),
('120d2881-b04f-4707-a925-e4d941f03201'),
('23af54a7-6666-4747-a74a-c2101cda59b0'),
('260d2ce5-f4f0-4a0b-aa0b-3e1d2b5fcfeb'),
('2710a913-13e7-4300-91f1-2646e2f8449e'),
('2cebc482-4917-4aa3-973b-2481619a78e7')
SELECT *
FROM table
where AssessmentId IN (SELECT assessmentId FROM #TempTable)
Since you want to specify multiple values, use a data type that supports multiple values (as opposed to a scalar variable). Here we're using a table variable:
Declare #tt table (value nvarchar(50) not null)
insert into #tt (value) values
('02ea2b81-07f0-4660-bca1-81563f65bf65'),('07728975-cb1d-484c-8894-14f5b793cbef'),('1071ee4f-a214-443f-8694-0b3e9d2dc77e'),
('120d2881-b04f-4707-a925-e4d941f03201'),('23af54a7-6666-4747-a74a-c2101cda59b0'),('260d2ce5-f4f0-4a0b-aa0b-3e1d2b5fcfeb'),
...
Select * from table where assessmentId IN(select value from #tt)
The name of a temporary table such as #t1 can be determined using
select #TableName = [Name]
from tempdb.sys.tables
where [Object_ID] = object_id('tempDB.dbo.#t1')
How can I find the name of a table valued variable, i.e. one declared by
declare #t2 as table (a int)
the purpose is to be able to get meta-information about the table, using something like
select #Headers = dbo.Concatenate('[' + c.[Name] + ']')
from sys.all_columns c
inner join sys.tables t
on c.object_id = t.object_id
where t.name = #TableName
although for temp tables you have to look in tempdb.sys.tables instead of sys.tables. where do you look for table valued variables?
I realize now that I can't do what I wanted to do, which is write a generic function for formatting table valued variables into html tables. For starters, in sql server 2005 you can't pass table valued parameters:
http://www.sqlteam.com/article/sql-server-2008-table-valued-parameters
moreover, in sql server 2008, the parameters have to be strongly typed, so you will always know the number and type of columns.
Table variable metadata is viewable in tempdb.sys.tables too. This is easily verifiable from the below
declare #t2 as table ( [38F055D8-25D9-4AA6-9571-F436FE] int)
SELECT t.name, t.object_id
FROM tempdb.sys.tables t

But you will notice the object name is auto generated and bears no relation to the variable name.
If you do not have a guaranteed unique column name that you can use to filter on as above and the table variable has at least one row in it you can (from SQL Server 2008 onwards) use %%physloc%% and DBCC PAGE to determine this information. Example below.
DECLARE #t2 AS TABLE ( a INT)
INSERT INTO #t2
VALUES (1)
DECLARE #DynSQL NVARCHAR(100)
SELECT TOP (1) #DynSQL = 'DBCC PAGE(2,' + CAST(file_id AS VARCHAR) + ',' +
CAST( page_id AS VARCHAR) +
',1) WITH TABLERESULTS'
FROM #t2
CROSS APPLY sys.fn_PhysLocCracker( %% physloc %% )
DECLARE #DBCCPage TABLE (
[ParentObject] [VARCHAR](100) NULL,
[Object] [VARCHAR](100) NULL,
[Field] [VARCHAR](100) NULL,
[VALUE] [VARCHAR](100) NULL )
INSERT INTO #DBCCPage
EXEC (#DynSQL)
SELECT VALUE AS object_id,
OBJECT_NAME(VALUE, 2) AS object_name
FROM #DBCCPage
WHERE Field = 'Metadata: ObjectId'
From Books Online:
A table variable behaves like a local variable. It has a well-defined scope, which is the function, stored procedure, or batch in which it is declared.
Given this, there should be no need to look up this value at run-time because you have to know it at design-time.
I don't believe you can, as table variables are created in memory not in tempdb.
On the topic of passing arbitrary lists/arrays into a SQL Server 2005 function or sproc, the least hokey way I know is to use an XML variable. If desired, that XML variable can be a strongly typed XML type that is associated w/ an XML Schema.
Given a list passed into a procedure/function as XML, you can extract that list into a table variable or temp table via "shredding".
"To shred" XML means to transform in the opposite direction--from XML to rowset(s). (The FOR XML clause causes a rowset to XML transformation.)
In the user-defined table function
CREATE FUNCTION [dbo].[udtShredXmlInputBondIdList]
(
-- Add the parameters for the function here
#xmlInputBondIdList xml
)
RETURNS
#tblResults TABLE
(
-- Add the column definitions for the TABLE variable here
BondId int
)
AS
BEGIN
-- Should add a schema validation for #xmlInputIssuerIdList here
--Place validation here
-- Fill the table variable with the rows for your result set
INSERT #tblResults
SELECT
nref.value('.', 'int') as BondId
FROM
#xmlInputBondIdList.nodes('//BondID') as R(nref)
RETURN
END
if the #xmlInputBondIdList is an XML fragment of the expected structure like that immediately below and is invoked as follows
DECLARE #xmlInputBondIdList xml
SET #xmlInputBondIdList =
'<XmlInputBondIdList>
<BondID>8681</BondID>
<BondID>8680</BondID>
<BondID>8684</BondID>
</XmlInputBondIdList>
'
SELECT *
FROM [CorporateBond].[dbo].[udtShredXmlInputBondIdList]
(#xmlInputBondIdList)
the result will be the rowset
BondId
8681
8680
8684
