Here condition is true then it return true otherwise return false
ALTER PROCEDURE spAppliedJobOrnot
--Here job is already applied then it return true otherwise return false
#check bit OUTPUT,
#UserId numeric,
#JobId numeric
AS
BEGIN
SET NOCOUNT ON;
if exists (SELECT 1 FROM StudentInbox_Activities WHERE JobId=#JobId and StudentId=#UserId and
JobAppliedDate is not null)
BEGIN
SET #check=1 --The job is applied so check=true
END
ELSE
BEGIN
SET #check=0;
END
END
GO
Here how to get the #check value
When using OUTPUT params, you need to return the value in the calling statement.
Have a lok at this example
SQL Fiddle DEMO
Procedure to do whatever
CREATE PROCEDURE FOO(#BAR INT OUTPUT)
AS
BEGIN
SET #BAR = -1
END;
And then calling statement
DECLARE #TADA INT = 0
EXEC FOO #TADA OUTPUT
SELECT #TADA
Since you have #check as output parameter, you can get this value from your application too.
If it is in C#, you can use something like the following,
SqlCommand cmd = new SqlCommand("SP_NAME");
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("#param1", param1);
cmd.Parameters.AddWithValue("#param2", param2);
cmd.Parameters.Add("#check", SqlDbType.Int);
cmd.Parameters["#check"].Direction = ParameterDirection.Output;
cmd.ExecuteNonQuery()
return Convert.ToInt32(cmd.Parameters["#check"].Value);
Add the following code after your if- end statement, before procedure end statement
select #check
Then run the procedure.

I am trying to concatenate the large number of id'd and to update the status of all id's.
For example:
aclid in (4604019,4604018,4604017,4604016,4604015,4604014,4604013,4604012,4604011,4604010,4604009,4604008,4604007,4604006,4604005,4604004,4604003,4604002,4604001,4604000,4603999,4603998,4603997,4603996,4603995,4603994,4603993,4603992,4603991,4603990,4603989,4603988)`
Please check my stored procedure:
ALTER PROCEDURE [dbo].[VT_ACLReportChangeStatus]
(#ChangeStatus nvarchar(50) = null,
#ACLId nvarchar(max))
AS
/* Exec VT_ACLReportChangeStatus 'Complete','4599473,4599472,4599471,4599469,4599468' */
BEGIN
UPDATE VT_ACLReport
SET Status = #ChangeStatus
WHERE ACLId IN (SELECT * FROM SplitDelimiterString(#ACLId,','))
END
Please check my code behind:
ACLId = ACLId.ToString().Trim(',');
using (SqlConnection con = new SqlConnection(cs))
{
cmd = new SqlCommand("VT_ACLReportChangeStatus", con);
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandTimeout = 3600;
cmd.Parameters.Add(new SqlParameter("#ACLId", SqlDbType.NVarChar,-1));
cmd.Parameters.Add(new SqlParameter("#ChangeStatus", SqlDbType.NVarChar, 50));
cmd.Parameters["#ACLId"].Value = ACLId;
cmd.Parameters["#ChangeStatus"].Value = ddlChangeStatus.SelectedItem.Text.ToString();
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
AclId column data type is bigint identity.
Please can you help me in concatenating large string and to update all rows whose aclid is present.
I would suggest, create one user defined table type in sql and one class in sourecode with your respective data. You can pass object of this class to sql and in your SP you can use join between main table and this table(which is received as input parameter) to update data.
Thanks all of you for your answers.. Actually it was silly mistake,while calling splitting function in Stored procedure. In function it was varchar(8000). :) solved it.
ALTER FUNCTION [dbo].[SplitDelimiterString] (#StringWithDelimiter VARCHAR(max), #Delimiter VARCHAR(max))
RETURNS #ItemTable TABLE (Item VARCHAR(max))
AS
BEGIN
DECLARE #StartingPosition INT;
DECLARE #ItemInString VARCHAR(max);
SELECT #StartingPosition = 1;
--Return if string is null or empty
IF LEN(#StringWithDelimiter) = 0 OR #StringWithDelimiter IS NULL RETURN;
WHILE #StartingPosition > 0
BEGIN
--Get starting index of delimiter .. If string
--doesn't contain any delimiter than it will returl 0
SET #StartingPosition = CHARINDEX(#Delimiter,#StringWithDelimiter);
--Get item from string
IF #StartingPosition > 0
SET #ItemInString = SUBSTRING(#StringWithDelimiter,0,#StartingPosition)
ELSE
SET #ItemInString = #StringWithDelimiter;
--If item isn't empty than add to return table
IF( LEN(#ItemInString) > 0)
INSERT INTO #ItemTable(Item) VALUES (#ItemInString);
--Remove inserted item from string
SET #StringWithDelimiter = SUBSTRING(#StringWithDelimiter,#StartingPosition +
LEN(#Delimiter),LEN(#StringWithDelimiter) - #StartingPosition)
--Break loop if string is empty
IF LEN(#StringWithDelimiter) = 0 BREAK;
END
RETURN
END
I have an SQL Query that looks like this -
CREATE PROCEDURE [dbo].[getMemberFundUnits]
-- Add the parameters for the stored procedure here
#member int,
#fundcode varchar(15),
#closingdate datetime
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 (CASE WHEN SUM(units) IS Null THEN 0 ELSE SUM(units) END) As fundunits
FROM pe_minv
WHERE pmi_member = #member AND pmi_fund = #fundcode AND pmi_invested <= #closingdate
END
When I run the stored procedure like this -
DECLARE #return_value as float /*int*/
EXEC #return_value = [dbo].[getFundUnits]
#member = 9738,
#fundcode = N'58193',
#closingdate = N'07/21/2011'
SELECT 'Return Value' = #return_value
I get two results. The first is the correct one which is -0.0060 and the second #return_value which is 0
This is also the case when I call the stored procedure from my code, I get a 0 back instead of the -0.0060 that I want.
This is how I am calling the stored procedure from my code:
Dim ds As New DataSet()
Dim cmd As New SqlCommand("getMemberFundUnits", conn)
cmd.CommandType = CommandType.StoredProcedure
Dim p_pm_member As New SqlParameter("#member", SqlDbType.Int)
p_pm_member.Value = pm_member
cmd.Parameters.Add(p_pm_member)
Dim p_fund_code As New SqlParameter("#fundcode", SqlDbType.VarChar)
p_fund_code.Value = fund_code
cmd.Parameters.Add(p_fund_code)
Dim p_period_closing_date As New SqlParameter("#closingdate", SqlDbType.DateTime)
p_period_closing_date.Value = period_closing_date
cmd.Parameters.Add(p_period_closing_date)
Dim da As New SqlDataAdapter(cmd)
da.Fill(ds)
Does anyone have any ideas why this might be happening?
Thanks!
DECLARE #return_value as int
Your variable is defined as int. Int can't hold decimal values, so the return value is rounded. Try to declare your var as float.
List of SQL Server data types
The RETURN is always int so it is truncated inside the stored procedure.
As per MSDN
RETURN [ integer_expression ]
You need to use an OUTPUT parameter that is float:
CREATE PROC [dbo].[getFundUnits]
#member...,
#fundcode...',
#closingdate...,
#SummedValue float OUTPUT
AS
...
SELECT #SummedValue = (CASE WHEN SUM(nits) IS Null THEN 0 ELSE SUM(units) END) As fundunits
...
GO
And you call it as
DECLARE #return_value as float
EXEC [dbo].[getFundUnits]
#member = 9738,
#fundcode = N'58193',
#closingdate = N'07/21/2011',
#return_value OUTPUT
SELECT 'Return Value' = #return_value
RETURN is used (if at all) only for execution status usually: meaningful data is via output parameters or a resultset. I no longer use RETURN...
Try declaring the return value as Decimal with precision.
DECLARE #return_value as decimal(18,4)
Also, why are you filling a dataset for only returning one column. Use a sqldatareader and retrieve the values as decimal. Dataset is very resource intensive.
I want to perform a search on a table to see if record exists. I do not want to perform insert or update after. I have done this already but somehow I cannot get this to work. On my asp.net page I cannot seem to get any value returned. The error is "input string not in correct format" I ma sure it is obvious but I cannot seem to see it now!
here is my code:
Dim con As New SqlConnection("connstring")
Dim cmd As New SqlCommand("checkname", con)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add(New SqlParameter("#d", SqlDbType.Int))
cmd.Parameters("#id").Value = TextBox1.Text
Dim para As New SqlParameter
para.Direction = ParameterDirection.ReturnValue
para.ParameterName = "returnvalue"
cmd.Parameters.Add(para)
con.Open()
cmd.ExecuteNonQuery()
Dim exists As Integer
exists = Convert.ToInt32(cmd.Parameters("returnvalue").Value)
If exists = 1 Then
Label1.Text = "You......"
ElseIf exists = 0 Then
Label1.Text = "You....."
End If
con.Close()
stored procedure:
CREATE PROCEDURE checkname
-- Add the parameters for the stored procedure here
#id int
AS
--This means it exists, return it to ASP and tell us
-- SELECT 'already exists'
IF EXISTS(SELECT * FROM attendees WHERE id = #id)
BEGIN
RETURN 1
END
ELSE
BEGIN
RETURN 0
END
You need to ensure that you are passing an integer.
int intValue;
if(!int.TryParse(TextBox1.Text, out intValue))
{
// Update your page to indicate an error
return;
}
cmd.Parameters.Add(New SqlParameter("id", SqlDbType.Int));
cmd.Parameters("id").Value = intValue;
(Technically you don't need the "#" character when
defining the parameters in the .NET
code.)
You have declared your procedure parameter as #d instead of #id. Also a return parameter cannot be an input parameter. The return value should be an exit code. You most likely want to create an output parameter and set that to 1 or zero inside of your stored procedure.
Edit: to clarify, the return value is generally regarded as an indicator of correct execution. Zero usually means success, where any other numeric value is generally regarded as an error code. That is why I recommended adding an output parameter instead of adding a return value parameter.
ExecuteNonQuery returns the number of rows affected. Therefore the return values that you set in your stored procedure are thrown away and will not be returned by the ExecuteNonQuery method.
ExecuteNonQuery is used to Insert / Delete / Update operations. Not for SELECT, you need either ExecuteScalar or ExecuteReader methods. This link will help you to know how to use output parameters : http://aspdotnet-suresh.blogspot.com/2010/10/introduction-here-i-will-explain-how-to.html
I am working on a Tag system for a news page designed in ASP.NET. For the system I require a TagExists method to check for tags within the database. The stored procedure I have written is below.
ALTER PROCEDURE [dbo].[Tags_TagExists](
#Tag varchar(50))
AS
BEGIN
If (EXISTS(SELECT * FROM dbo.Tags WHERE LOWER(#Tag) = LOWER(Tag)))
RETURN 1
ELSE
RETURN 0
END
When I call this method however 0 is always returned. I am using the following code to call the method
Public Shared Function TagExists(ByVal name As String) As Boolean
Dim result As Boolean
Using conn As SqlConnection = New SqlConnection(ConnectionString)
Dim cmd As New SqlCommand("Tags_TagExists", conn)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.AddWithValue("#Tag", name)
conn.Open()
result = Convert.ToBoolean(cmd.ExecuteScalar())
conn.Close()
End Using
Return result
End Function
I have tried switching the procedure to return 0 if the tag exists and 1 if it does not and it still returns 0 despite the exact same testing conditions. I have also returned the actual select query and it has complained of the Tag "news" (my test item) not being an int on execution showing the select itself is definitely properly formed.
If anyone can shed some light on this, Thanks
Michael
It should probably be a function, but here is the stored proc code:
ALTER PROCEDURE [dbo].[Tags_TagExists](
#Tag varchar(50))
AS
BEGIN
If EXISTS(SELECT 1 FROM dbo.Tags WHERE LOWER(#Tag) = LOWER(Tag))
BEGIN
SELECT 1
END
ELSE
BEGIN
SELECT 0
END
END
You're returning from a Stored Procedure, not getting a single scalar value from a SQL statement.
I'm assuming this is a simple example and you have other processing you want to handle inside the Stored Procedure. In that case, using the Stored Procedure and return value is the right way to go. You need to handle the return value from the Stored Procedure in your C# code (Please excuse any syntax errors, my VB.NET is a bit rusty):
Public Shared Function TagExists(ByVal name As String) As Boolean
Dim result As Boolean
Using conn As SqlConnection = New SqlConnection(ConnectionString)
Dim cmd As New SqlCommand("Tags_TagExists", conn)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.AddWithValue("#Tag", name).
Dim retVal As SqlParameter = _
cmd.Parameters.Add("return_value", SqlDbType.Int)
retval.Direction = ParameterDirection.ReturnValue
conn.Open()
cmd.ExecuteNonQuery()
result = System.Convert.ToBoolean(retval.Value)
conn.Close()
End Using
Return result
End Function
If you're strictly interested in the return value and your Stored Procedure isn't performing any other use, then convert it to a simple select statement (or function). Your use of ExecuteScalar would work in that case.
Please try using SELECT 1 and SELECT 0 instead of RETURN statement
Hope that helps,
I am using following storedprocedure
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
Alter PROCEDURE [dbo].[GetUserDetailsByUserID]
(
#UserId varchar(100)
)
AS
BEGIN
IF EXISTS(Select * from Registration where UserId=#UserID)
BEGIN
Select
[Name],
[UserId],
[PermanentAddress],
[TemporaryAddress],
[OfficePhoneNo],
[ResidentialPhoneNo],
[MobileNo],
[Email],
[ContactPerson],
[C_OfficePhoneNo],
[C_ResidentialPhoneNo],
[C_MobileNo],
[C_Email],
[Project],
[TotalAmount]
From
Registration
Where
UserId=#UserId
END
END
I am using following code in vb
Public Function GetUserDetailsByUserID(ByVal strUserId As String) As DataTable
Try
Dim db As Database = DatabaseFactory.CreateDatabase()
Dim DbCommand As DbCommand = _
db.GetStoredProcCommand("GetUserDetailsByUserID")
db.AddInParameter(DbCommand, "#UserId", DbType.String, strUserId)
Return db.ExecuteDataSet(DbCommand).Tables(0)
Catch ex As Exception
Return New DataTable()
End Try
End Function
If details corresponding to userid does not exist in registration table, db.ExecuteDataSet(DbCommand).Tables(0) shows one error as cannot find Table(0). What modification in stoted procedure i hve to make to get rid of this error?
You can simply get rid of the IF EXISTS. When the record doesn't exist, you will get an empty table (which I think is what you want, looking at your sample code)
The procedure will not always return a record set. If there is no record set then Tables will be empty and Tables(0) will fail and return an error. You should just return the selection rather than only selecting if the record exists. Your code can then check for an empty returned record set.
In the VB code, change
Return db.ExecuteDataSet(DbCommand).Tables(0)
to
Dim Ds as DataSet = db.ExecuteDataSet(DbCommand)
If Ds.Tables.Count = 1 Then
Return Ds.Tables(0)
Else
Return New DataTable()
End If
Also, remove the If Exists from the Stored Procedure, since if the row exists, you will force the database to search twice in the table for the record where UserId=#UserID.
