I have a list ClaimData in C# and it has three items Date, Type and Description
There can be multiple rows in this as below,
ClaimData
Date Type Description
01/02/2012 "Medical" "Its a medical"
05/02/2013 "Theft" "Its a Theft"
01/02/2014 "Test" "Its a Test"
I want to pass this whole data to a stored procedure in one go to the sql server, so that I can reduce the database hits. I have written stored procedure which can iterate through this list and insert them in a table.
How to achieve by manipulating the list object could be passed to the stored procedure as a parameter?
You will need to do a couple of things to get this going, since your parameter is getting multiple values you need to create a Table Type and make your store procedure accept a parameter of that type.
Since you are passing a TABLE as a parameter you will need to create a TABLE TYPE something as follows
TABLE TYPE
CREATE TYPE dbo.ClaimData AS TABLE
(
[Date] DATE
[Type] VARCHAR(50)
[Description] VARCHAR(100)
)
GO
Stored Procedure to Accept That Type Param
CREATE PROCEDURE mainValues
#TableParam ClaimData READONLY --<-- Accepts a parameter of that type
AS -- Note it is ReadOnly
BEGIN
SET NOCOUNT ON;
--Temp table to store the passed values
-- since the passed parameter is only Read only and you
-- cannot make any changes to the parameter so if you need to
-- manipulate the data inside parameter you will need to get it
-- into a Table vaiable.
-- Declare a Table variable
DECLARE #tmp_values table(
[Date] DATE
[Type] VARCHAR(50)
[Description] VARCHAR(100)
);
--Get values into that Table variable
INSERT INTO #tmp_values ([Date],[Type],[Description])
SELECT [Date],[Type],[Description] FROM #TableParam
-- Do other cool stuff with your passed data
SELECT * FROM #tmp_values --<-- For testing purpose
END
EXECUTE PROC
Declare a variable of that type and populate it with your values.
DECLARE #Table ClaimData( --<-- Declare a variable of your type
[Date] DATE
[Type] VARCHAR(50)
[Description] VARCHAR(100)
);
-- Populate the variable
INSERT INTO #Table ([Date],[Type],[Description])
SELECT [Date],[Type],[Description] FROM Source_Table
EXECUTE mainValues #Table --<-- Stored Procedure Executed
I sent all three column as a string using string builder and delimeter '|'
DateString = '01/02/2012|05/02/2013|01/02/2014'
TypeString = 'Medical|Theft|Test'
DescString = "Its a medical|..."
On database side I used a function to delimit these strings and inserted all these values in a temp table. This solved my problem.

I am trying to use table-valued parameter to pass a column to "IN" clause in SQL Server. To do so I need to declare a type of table.
The SQL expression:
DECLARE TYPE myType AS TABLE( myid varchar(50) NULL);
is giving the error:
'myType' is not a recognized CURSOR option.
Replacing DECLARE to CREATE is working good.
Using "CREATE" is requiring to drop this type in any next SQL calls like:
IF TYPE_ID('myType') IS NOT NULL DROP TYPE myType;
But I would like to use the type "myType" just within this SQL expression only.
How to declare a type as table without creating it permanently and without deleting it in all requests?
DECLARE requires the following sinthax:
DECLARE #LastName NVARCHAR(30), #FirstName NVARCHAR(20), #Country NCHAR(2);
With DECLARE, you can:
To assign a variable name(using #).
To assign a Variable Type
To assign a NULL default Variable value
So "DECLARE TYPE" is not a valid statement.
Have a look to temporary tables in sql.
You can create a temporary table in sql with the following code:
CREATE TABLE #TempTable
(
name VARCHAR(50),
age int,
gender VARCHAR (50)
)
INSERT INTO #TempTable
SELECT name, age, gender
FROM student
WHERE gender = 'Male'
With a temporary table, you can store a subset of data from a standard table for a certain period of time.
Temporary tables are stored inside “tempdb” which is a system database.
I have a stored procedure which contains #Parm parameter with Nvarchar data type which will search data from table XYZ which will store data of multi language data (Nvarchar) like 'బుక్స్ లవర్స్ కి విజ్ఞప్తి' or 'समाचार पत्र' etc.
Whenever I am trying to search using stored procedure by passing search values we not getting values.
The below is code snippet for procedure:
CREATE PROCEDURE [dbo].Searc_String #SearchParam nvarchar(max)
AS
BEGIN
SELECT * FROM Xyz WHERE columnsname LIKE N'%'+#SearchParam+'%'
END
And trying to call like below:
EXEC [dbo].Searc_String #SearchParam = N'బుక్స్ లవర్స్ కి విజ్ఞప్తి'
Is there a way to input multiple values in a single parameter of a scalar-valued function in SQL Server 2008 R2 and have it filter data by that parameter using both values?
For example I would like to do the following
SET #Salesperson='BILL' OR 'MOSES'
SELECT Sum(SalesDollars)
FROM Invoices
WHERE Invoices.Salesperson = #Salesperson
I attempted to use the following as the WHERE clause, but this didnt work either.
SET #Salesperson='BILL','MOSES'
SELECT Sum(SalesDollars)
FROM Invoices
WHERE Invoices.Salesperson IN (#Salesperson)
Would it be easier if i were dealing with integers as opposed to varchar values?
Any help would be absolutely appreciated!
You need to use table-valued parameters. Look it up on technet or msdn
Best part of it that your table-valued parameters can have multiple columns.
Note however that you have to define TVP parameter as readonly. So if you want to return similar set from your function you will need to create another variable inside your function.
Example:
CREATE TYPE Names AS TABLE
( Name VARCHAR(50));
GO
/* Create a procedure to receive data for the table-valued parameter. */
CREATE PROCEDURE dbo.mySP
#n Names READONLY
AS
SELECT Sum(SalesDollars)
FROM
WHERE Invoices.Salesperson in (select Name from #n)
GO
CREATE FUNCTION dbo.myFun(#n Names READONLY) returns int
AS
SELECT Sum(SalesDollars)
FROM
WHERE Invoices.Salesperson in (select Name from #n)
GO
/* Declare a variable that references the type. */
DECLARE #names AS Names;
/* Add data to the table variable. */
INSERT INTO #names (Name)
VALUES ('BILL'),('MOSES')
-- using stored procedure with TVP
EXEC dbo.mySP #names
-- using function with TVP
select dbo.myFun(#names)
GO
This could be done this way:
SET #Salesperson='BILL,MOSES'
SELECT *
FROM YourTable
WHERE Invoices.Salesperson IN (SELECT * FROM dbo.split(#Salesperson,','))
This is how you split the values.
I would typically do this using a user defined table type: SQL Fiddle Example.
CREATE TYPE <schema>.SalespersonList AS TABLE
(
Name varchar(32)
)
You may have to grant execute permissions on the type:
GRANT EXECUTE ON TYPE::<schema>.SalespersonList TO <user>
Then you can create a function to use it:
CREATE FUNCTION <schema>.fnGetTotalSales
(
#nameList <schema>.SalespersonList READONLY
)
RETURNS INT
AS
BEGIN
DECLARE #ret INT
SELECT #ret = Sum(SalesDollars)
FROM Invoices i
INNER JOIN #nameList nl ON nl.Name = i.Salesperson
RETURN #ret
END
Then you would just insert your list into the type and call the function:
DECLARE #salesPersonList <schema>.SalespersonList
INSERT INTO #salesPersonList (Name)
SELECT 'Bill'
UNION
SELECT 'Moses'
SELECT <schema>.fnGetTotalSales(#salesPersonList)
Is it possible to return or output a #tableVariable in SQL Server?
For example for the following stored procedure, how do I return the #TSV table variable?
ALTER PROCEDURE MyStoredProdecure
#Parameter1 INT,
#Parameter2 INT
AS
BEGIN
DECLARE #TSV TABLE
(
Transition_Set_Variable_ID INT,
Passed BIT
)
INSERT INTO #TSV
{ some data }
END
You cannot do it directly. Table variables are valid for READONLY input.
If you have no other data being returned from the stored procedure, you can select from the #TSV at the end and have the caller capture the output, e.g.
ALTER PROCEDURE MyStoredProdecure
#Parameter1 INT,
#Parameter2 INT
AS
BEGIN
DECLARE #TSV TABLE
(
Transition_Set_Variable_ID INT,
Passed BIT
)
INSERT INTO #TSV
{ some data }
SELECT * FROM #TSV
END
Caller
DECLARE #outerTSV TABLE
(
Transition_Set_Variable_ID INT,
Passed BIT
);
insert into #outerTSV
exec MyStoredProdecure 1, 2;
Alternatively, if the SP is really as simple as you showed, turn it into a table valued function instead.
No, but you can write a table valued function that returns a table.
create function MyTVF
#Parameter1 INT,
#Parameter2 INT
returns #tsv table
(
Transition_Set_Variable_ID INT,
Passed BIT
)
AS
BEGIN
INSERT INTO #TSV
{ some data }
return
END
Table Valued Parameters can only be used for input only, not output.
Depending on what your end goal is, here are some options:
change the sproc to a table-valued function to return a TABLE, that can then be used inline in another statement
simply SELECT the data from the #TSV table var at the end of your sproc
return an XML OUTPUT parameter (get a grubby feeling suggesting this, but just to highlight one way to return multiple rows actually using an OUTPUT parameter)
If you go for a Table Valued Function, ideally create an inline one if it is simple as it looks in your case:
e.g.
CREATE FUNCTION dbo.Func()
RETURNS TABLE
AS
RETURN
(
SELECT Something
FROM Somewhere
WHERE x = 1
)
I'm using SSRS for reporting and executing a stored procedure to generate the data for my reports
DECLARE #return_value int
EXEC #return_value = [dbo].[MYREPORT]
#ComparePeriod = 'Daily',
#OverrideCompareDate = NULL,
#PortfolioId = '5,6',
#OverrideStartDate = NULL,
#NewPositionsOnly = NULL,
#SourceID = 13
SELECT 'Return Value' = #return_value
GO
In the above when I passed #PortfolioId = '5,6' it is giving me wrong inputs
I need all records for portfolio id 5 and 6 also is this correct way to send the multiple values ?
When I execute my reports only giving #PortfolioId = '5' it is giving me 120 records
and when I execute it by giving #PortfolioId = '6' it is giving me 70 records
So when I will give #PortfolioId = '5,6' it should have to give me only 190 records altogether, but it is giving me more no of records I don't understand where I exactly go wrong .
Could anyone help me?
thanks
all code is too huge to paste , i'm pasting relevant code please suggest clue.
CREATE PROCEDURE [dbo].[GENERATE_REPORT]
(
#ComparePeriod VARCHAR(10),
#OverrideCompareDate DATETIME,
#PortfolioId VARCHAR(50) = '2', --this must be multiple
#OverrideStartDate DATETIME = NULL,
#NewPositionsOnly BIT = 0,
#SourceID INT = NULL
) AS
BEGIN
SELECT
Position.Date,
Position.SecurityId,
Position.Level1Industry,
Position.MoodyFacilityRating,
Position.SPFacilityRating,
Position.CompositeFacilityRating,
Position.SecurityType,
Position.FacilityType,
Position.Position
FROM
Fireball_Reporting.dbo.Reporting_DailyNAV_Pricing POSITION WITH (NOLOCK, READUNCOMMITTED)
LEFT JOIN Fireball.dbo.AdditionalSecurityPrice ClosingPrice WITH (NOLOCK, READUNCOMMITTED) ON
ClosingPrice.SecurityID = Position.PricingSecurityID AND
ClosingPrice.Date = Position.Date AND
ClosingPrice.SecurityPriceSourceID = #SourceID AND
ClosingPrice.PortfolioID IN (
SELECT
PARAM
FROM
Fireball_Reporting.dbo.ParseMultiValuedParameter(#PortfolioId, ',') )
This can not be done easily. There's no way to make an NVARCHAR parameter take "more than one value". What I've done before is - as you do already - make the parameter value like a list with comma-separated values. Then, split this string up into its parts in the stored procedure.
Splitting up can be done using string functions. Add every part to a temporary table. Pseudo-code for this could be:
CREATE TABLE #TempTable (ID INT)
WHILE LEN(#PortfolioID) > 0
BEGIN
IF NOT <#PortfolioID contains Comma>
BEGIN
INSERT INTO #TempTable VALUES CAST(#PortfolioID as INT)
SET #PortfolioID = ''
END ELSE
BEGIN
INSERT INTO #Temptable VALUES CAST(<Part until next comma> AS INT)
SET #PortfolioID = <Everything after the next comma>
END
END
Then, change your condition to
WHERE PortfolioId IN (SELECT ID FROM #TempTable)
EDIT
You may be interested in the documentation for multi value parameters in SSRS, which states:
You can define a multivalue parameter for any report parameter that
you create. However, if you want to pass multiple parameter values
back to a data source by using the query, the following requirements
must be satisfied:
The data source must be SQL Server, Oracle, Analysis Services, SAP BI
NetWeaver, or Hyperion Essbase.
The data source cannot be a stored procedure. Reporting Services does
not support passing a multivalue parameter array to a stored
procedure.
The query must use an IN clause to specify the parameter.
This I found here.
I spent time finding a proper way. This may be useful for others.
Create a UDF and refer in the query -

USE THIS
I have had this exact issue for almost 2 weeks, extremely frustrating but I FINALLY found this site and it was a clear walk-through of what to do.
http://blog.summitcloud.com/2010/01/multivalue-parameters-with-stored-procedures-in-ssrs-sql/
I hope this helps people because it was exactly what I was looking for
Either use a User Defined Table
Or you can use CSV by defining your own CSV function as per This Post.
I'd probably recommend the second method, as your stored proc is already written in the correct format and you'll find it handy later on if you need to do this down the road.
Cheers!
I think, below procedure help you to what you are looking for.
CREATE PROCEDURE [dbo].[FindEmployeeRecord]
#EmployeeID nvarchar(Max)
AS
BEGIN
DECLARE #sqLQuery VARCHAR(MAX)
Declare #AnswersTempTable Table
(
EmpId int,
EmployeeName nvarchar (250),
EmployeeAddress nvarchar (250),
PostalCode nvarchar (50),
TelephoneNo nvarchar (50),
Email nvarchar (250),
status nvarchar (50),
Sex nvarchar (50)
)
Set #sqlQuery =
'select e.EmpId,e.EmployeeName,e.Email,e.Sex,ed.EmployeeAddress,ed.PostalCode,ed.TelephoneNo,ed.status
from Employee e
join EmployeeDetail ed on e.Empid = ed.iEmpID
where Convert(nvarchar(Max),e.EmpId) in ('+#EmployeeId+')
order by EmpId'
Insert into #AnswersTempTable
exec (#sqlQuery)
select * from #AnswersTempTable
END
