StrdPrcdr Param Get All Values
Apr 21, 2008
Hello....
I am trying for several weeks to figure out how can I create a stored procedure with parameters that returns all rows from a column (even then Nulls) when the parameter value is not set (or is '%', or anything tha might be. In a few words, in case the user hasn't input any data).
I 've created a WHERE clause that goes like this: WHERE fieldName LIKE @param + N'%' OR IS NULL
Well this query returns all rows in case the user hasn't input data but if the user inputs data it returns the correct rows but it is also returns null fields.
Thanks a lot in advance!
Manolo....

Hey all,
1) I have a report with many parameters that I want users to be able to pick from. Allow them to pick 1, many or all to build their report dynamically. I'm all set on the TSQL side, but on the Reporting Services side I have to allow each parameter to be null with a default of NULL. In by doing this, the report will auto run, which I do not want to happen. The only resolution I've found thus far was by adding a parameter that does nothing, with a NULL default value. Yet It sticks out like a sore thumb on the report and I want to get rid of it. If I check in "Hidden" in the parameter options, my report errors out stating that the parameter requires a value.
2) Is it possible to have a parameter that has available values from a dataset have a NULL checkbox like those of parameters that do not have available values?
3) Is it possible to add back/forward buttons inside of a report instead of just at the report header by default?
Thanks!

How do I display multiple parameter values on report page from a multi-value report parameter. For example, I have a report parameter where users can select multiple attendance codes and I want them displayed at the top of the report after it's run.
Currently, only the first value is showing on the report.
Thanks.

I have one sp which has param name as cordinatorname varchar(max)
In where condition of my sp i passed as
coordinator=(coordinatorname in (select ltrim(rtrim(value)) from dbo.fnSPLIT(@coordinatorname,',')))
But now my promblm is for @coordinatorname i have values as 'coorcinator1', 'coordinato2,inc'
So when my ssrs report taking these values as multiselect, comma seperated coordinator2,inc also has comma already.

I would like to test following DMX, but it seems like we cannot use @param in DMX. If i indeed need what other tricks can avoid this constraint?
Declare @HCVS_MemberId nvarchar(15);
INSERT INTO test
(HCVS_MemberId, HCVS_MeasureDate, SysPressure, DiaPressure, Pluse)
OPENQUERY(Healthcare,
'SELECT TimeIndex, Quantity
FROM v_VitalSignForecast
WHERE HCVS_MemberId=@HCVS_MemberId AND HCVS_MeasureDate>=@From AND HCVS_MeasureDate<=@To')
Thanks,

is there a way in t-sql to pass a db name as a parameter, so that select * from [@passedDB].[dbo].[tableName] would work? Without dynamically building and executing the sql statement?

The following stored procedure sets a value for the @@RowCount global variable.
How do I make use of it in the Data Access Layer?
When I set the SPROC as the source for the object, the value numberRows does not appear to be an option. In the end I just want to set the value of @@RowCount to a Label.Text
What should I do?ALTER PROCEDURE dbo.ap_Select_ModelRequests_RequestDateTime
@selectDate datetime
,@selectCountry Int
AS
SELECT DISTINCT configname FROM ModelRequests JOIN
CC_host.dbo.usr_cmc As t2 ON
t2.user_id = ModelRequests.username JOIN
Countries ON
Countries.Country_Short = t2.country
WHERE RequestDateTime >= @selectDate and RequestDateTime < dateadd(dd,1, @selectDate)
AND configname <> '' AND interfacename LIKE '%DOWNLOAD%' AND result = 0 AND Country_ID = @selectCountry
ORDER BY configname
SELECT @@RowCount As numberRows
GO

I'm working with a dataset something like this:
TypeID Sales($)
------ -------
1 123.45
1 47.98
2 9.21
3 87.23
3 99.88
4 123.43
And a multivalued parameter that lets the user select which TypeIDs specifically he wants to see:
ParamID ParamValue
1 Q1
2 Q2
3 Q3
4 Q4
And in my Report, I have data showing up something like this:
CountofAllSales: 6
SumOfAllSales: 491.18
CountofCustomSales: (count of sales with type specified in parameter)
SumOfCustomSales: (sum of sales with type specified in parameter)
The count and sum of custom sales should show -ONLY- the numbers from the TypeIDs selected in the multi-value parameter. But the CountAll and SumAll show everything, regardless. This is where I run into problems. I can't seem to find an "in" clause in the SSRS expressions. If the TypeID parameter was single value, I could write something like this
Expression for CountOfCustomSales:
=SUM(iif(Fields!TypeID.Value = Parameters!TypeID.Value, 1, 0))
However, since its multi-valued, that won't work. You'd have to write something like:
=SUM(iif(Fields!TypeID.Value = Parameters!TypeID.Value(0), 1, 0)) +
SUM(iif(Fields!TypeID.Value = Parameters!TypeID.Value(1), 1, 0)) +
....
SUM(iif(Fields!TypeID.Value = Parameters!TypeID.Value(length), 1, 0))
And obviously this doesn't work when you don't know exactly how many elements are going to be selected.
What would be ideal would be something like an "in" clause, but I can't find any such functionality or think how to write my own function:
=SUM(iif(Fields!TypeID.Value in
Parameters!TypeID.Values, 1, 0))
Short of modifying the StoredProc itself (and for me, that means red tape. :( :( ) can anyone think of a way to count/sum only the values specified in an MVP??

Hi AllMy query is as follows:SELECT STRINGTEXT, TOKENIDFROM WEBSTRINGSWHERE TOKENID IN (6,20,234,19,32,4,800,177)All I want is my resultset to come back in the order that I have defined inthe IN clause, but unfortunately SQL is trying to be too helpful and sortsthe numbers in the IN clause so that the resultset comes back with a TOKENIDorder of 4,6,19,20,32,177,234,800.I don't want this bloody order I want 6,20,234,19,32,4,800,177!!Sorry for my rant, but its got my hot under the collar.Is there anyway round this?ThanksYobbo

Is there a limit to how many items you can have in a multi value param list. I have 20 items in an activity type param and when I chose "Select All" and run the report, it doesn't return. I opened profiler and picked up the following statement sent to SQL:
exec sp_executesql N'SELECT de.employeenumber as Employee_Id,de.employeelastname + '', '' + de.employeefirstname + '', '' + case when de.employeemiddlename=''N/A'' then '''' else de.employeemiddlename end as Employee_Name,da.activitytype as Activity_Type,da.activitycode as Activity_Code,da.activityname as Activity_Name,dd.fulldate as Completion_Date,das.currentattemptstatus as Current_Attempt,das.successstatus as Success_Status,das.completionstatus as Completion_Status,das.registrationstatus as Registration_Status,fa.score as Score,fa.dimgradeid as GradeId
FROM dimemployee de inner join factattempt fa on (de.dimemployeeid = fa.dimemployeeid) inner join dimattemptstatus das on (fa.dimattemptstatusid = das.dimattemptstatusid) inner join dimactivity da on (fa.dimactivityid = da.dimactivityid) inner join dimdate dd on (fa.attemptenddateid = dd.dimdateid)
WHERE
de.employeenumber = (@EmployeeId) and da.activitytype in (N''CBT'',N''Course'',N''Dart'',N''Discuss'',N''Document'',N''Evaluator'',N''JPM'',N''Lesson Plan'',N''Module'',N''Observation'',N''Procedure'',N''PSG'',N''Qual'',N''Read'',N''Reference'',N''Session'',N''Sign-off'',N''Simulator'',N''Task'',N''Trainer'')
and das.isvalidattempt = ''Yes'' and ((@LastAttempt=1 and das.currentattemptstatus = ''Yes'') or (@LastAttempt=0 and das.currentattemptstatus in (''Yes'',''No''))) and das.lmsmartcompletionstatus in (@CompletionStatus) and (dd.fulldate >= @StartDt or @StartDt is NULL) and (dd.fulldate <= @EndDt or @EndDt is NULL)
ORDER BY de.employeefirstname + '' '' + de.employeelastname,da.activitytype,da.activityname,dd.fulldate',N'@EmployeeId int,@LastAttempt nvarchar(1),@CompletionStatus nvarchar(10),@StartDt nvarchar(4000),@EndDt nvarchar(4000)',@EmployeeId=108001,@LastAttempt=N'1',@CompletionStatus=N'Successful',@StartDt=NULL,@EndDt=NULL
If I take any one of the items in "da.activitytype in" out (for example....N''Trainer'')...the query is fine. But if I run it as is, it never returns. I have also reduced the number of items in the MVP to 19 and "Select All" and it runs fine...it just bombs when I have 20 and Select All. Any ideas?

I've got a stored procedure and one of the parameters is a DateTime. But no matter what I do to the string that's passed into the form for that field, it doesn't like the format. Here's my code: SqlConnection conn = new SqlConnection(KPFData.getConnectionString());
SqlCommand cmd = new SqlCommand("KPFSearchName", conn);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter param = cmd.Parameters.Add("@DOB", SqlDbType.SmallDateTime);
param.Direction = dir;
param.Value = txtDOB.Text;
// also have tried this:
param.Value = Convert.ToDateTime(txtDOB.Text);
// and
param.Value = Convert.ToDateTime(txtDOB.Text).ToShortDateString;
No matter what I do I always get a formatting error - either I can't convert the string to a DateTime, or the SqlParameter is in the incorrect format, or something along those lines. I've spent a couple hours on this and hoping someone can point out my obvious mistake here...??Thanks for your help!!eddie

Hello,
I have a table with a foreign key field. I need to retrieve all the records where the foreign key matches any of a set. In plain ol' SQL this is accomplished with the IN(a,b,c) statement but I can't get that to work in a stored procedure.
How would I do this? I can imagine that I could parse the input string and create a temporary table and use that to do a join but that seems rather convoluted.
Any tips highly appreciated! If I'm not being clear I'll gladly post more details.
Thanks,
Noc

Hello everyone,
I am working through a tutorial and have stumbled into something that does not quite make sense to me. I was wondering if someone could help me understand this.
I have created this SP, this all makes sense to me due to the assignment of the artistname column value to the @artistname variable. In other words what is on the right of the equal sign is assigned to what is on the left.
create procedure ShowPopStyle
@style varchar(30),
@artistname varchar(30) output
as
select @artistname = artistname
from artists
where style = @style
go
Now when you execute this SP, what does not makes sense to me is if I need to declare a variable to hold the output, which I presume is null, shouldn't the @returnname be on the left side of the equal sign instead of the right?
declare @returnname varchar(30) -- variable for the output from the procedure
exec showpopstyle 'Pop', @artistname = @returnname output
print @returnname
Thanks
Kevin

I've decalred this stored procedure with a simple where and like statement. The problem is I don't see any result.
Here is my code
create procedure sp_Select_ProfileNames
@NameSearch varchar(50)
as
select ProfileFirstName +' '+ ProfileLastName as ProfileName
from Profiles
where ProfileLastName like '%@NameSearch%';
When i change this line:

where ProfileLastName like '%Bil%';
I see names starting with Bil, but when i enter Bil as param, I don't get anything.
What's wrong here ?

I have a rs report with a parameter(named Site) that is defined as multi-value. What I am trying to do is call the report from an html form with the parameter populated with a comma seperated list of values. The html code is a minimally modified version of the code found in ch. 11 of the hitchhikers guide(code included below after the solid line). If I don't select any items, then execution is fine.

Hello,
I have a VB.NET stored procedure as below:
Code Snippet
Partial Public Class StoredProcedures
Public Shared Sub My_UpdateCountsManaged( ByRef paramInOut As Integer)
'here I perform update statement using "paramInOut" passed form calling code
.......
'then I return value to the calling code
paramInOut = 555
End Sub
End Class
Calling code specifies a parameter like this:
Code Snippet
Dim param as Sqlparameter = New SqlParameter("@paramInOut", SqlDbType.Int)
param.Direction = ParameterDirection.InputOutput
param.Value = 999
cmd.Parameters.Add(param)
When I execute the code, it surely gets back "555" from SP, the problem is that SP never gets "999" from calling code despite ParamDirection is InputOutput. It always receives 0. I am afraid I don't understand something fundamental ?
Any help would be appreciated.
Thanks a lot,Fly.

Reading about SQL Injection attacks I came across this example:
SSN="172-32-9999';DROP DATABASE pubs --"
SqlQuery = "SELECT au_lname, au_fname FROM authors WHERE au_id = '" + SSN + "'"
One remedy given was a parameterized query as follows:
Dim cmd As new SqlCommand("SELECT au_lname, au_fname FROM authors WHERE au_id = @au_id")
Dim param = new SqlParameter("au_id", SqlDbType.VarChar)
param.Value = SSN
cmd.Parameters.Add(param)
Why does this parameter which is defined as a varchar solve the problem? It's defined as a varchar, basically a string. Why is the result different in the solution? How is the query string in the second sample different from the one in the first? A simple question I know, but I've been wondering.
Thanks

Hi,
My package takes 1 global variable and I have set up jobs to run this SSIS with different variable values.
I select the package using the UI provided via the job set up screen. The job step type is Operating system (CmdExec).
When package are run by job, it seems that the job can not find the package. But, how can it not find the package when the package was selected from a list that the UI displayed? The error is below.
"Executed as user: <<LOGGEDIN USER(with admin right)>>. The process could not be created for step 1 of job 0xFECED6C09CC650489084E91C2FCF52FB (reason: The system cannot find the file specified). The step failed."

I want to pass a single char to a query and use that to set two flags.
(
@ID int,
@AssessedID int,
@CompetencyID int,
@Status char,
@Creator int
)
AS
UPDATE P4_Assessment
SET P4_Cancelled_f = (@Status = ('C')),
P4_Competent_f = (@Status = ('P')),
P4_Date = getdate(),
P4_Creator = @Creator
WHERE P4_ID = @ID
I want to set the P4_Cancelled_f to true (if @Status = 'C') or false if it doesn't.
This sort of syntax is fine in C#, but fails in a query. I also tried using IN (@Status IN ('C'))
Is this sort of logic possible in TSQL or should I use two parameters and set them in my code as 1 or 0?
TIA

Hi,
I'm exporting some data from a table to fixed-width file using SSIS.
The query inside the package is:
SELECT col1, col3, col6 FROM Table1
WHERE code = 5 AND status = 'S'
The 'code' value will be passed from the front-end.
How can I make the query dynamically take the 'code' value and export to a file?
If a user selects 'code' as 7 , then the query should change to
SELECT col1, col3, col6 FROM Table1
WHERE code = 7 AND status = 'S'
and with this it has to export to a file.
Is this possible? If so, any suggestions on how to do it? !!!
Thanks,
Siva.

Please help me on this one.
I need to return a value to VB.
I've tried returning a numeric value NUMERIC(25,20) via an output parameter but this didn't work. I'm know at a point in wich I created a bigint and multiplied the value so that the decimals are gone. However it only returns NULL?!?!?!?!!?!?
Here's part of my stored proc
CREATE PROCEDURE dbo.uspCalcWeightedAverage @StartDate2 varchar(10), @EndDate2 varchar(10), @InMarket nvarchar(50), @InProductType int, @InWeekDay int, @WeightedAverage bigint OUTPUTAS......SELECT @WeightedAverage = cast(10000000000 * (SUM(HHF.FACTOR) / COUNT(PDF.FLAG)) as bigint)FROM TBL_PRODUCTDEFS PDF INNER JOIN #DATESBETWEENINTERVAL DBI ON DATEPART(HH, [DBI].[DATE]) = [PDF].[HOUR] INNER JOIN tbl_historichourlyfactors HHF ON DATEPART(D,DBI.DATE) = HHF.DayID AND [PDF].[HOUR] = [HHF].[HOUR] AND DATEPART(M,DBI.DATE) = [HHF].[Month]WHERE PDF.MARKETID = @InMarketID AND PDF.PRODUCTTYPEID = @InProductTypeID AND [PDF].[WD-WE] = @InWeekDay AND HHF.MARKETID = @InMarketID AND PDF.FLAG = 1GROUP BY FLAG
When I retrieve the output param it returns a NULL value. the properties in VB say that the parameter has the following props:
attribute 64 (Long)
NumericScale 0 (Byte)
Precision 19 (Byte)
Size 0 (ADO_LNGPTR)
Type adBigInt
Value Null
I try to return it with the following code (got the code from a friend)

The proc below does two queries that are functionally identical. The only difference is that one LIKE 'foo%', and the other uses LIKE @searchText, where @searchText = 'foo%'.
But the first does an index seek, and the second does an index scan -- and it makes a big difference in performance. (Timing stats are below.)
How can I make the second query seek instead of scanning?
CREATE PROCEDURE test_like
@searchText nvarchar(64)
AS
-- Straight literal string search
SELECT companyId
FROM companies
WHERE searchbrand LIKE 'foo%'
-- With param
SELECT companyId
FROM companies
WHERE searchbrand LIKE @searchText
OPTION(OPTIMIZE FOR(@searchText = 'foo%'))
GO
EXEC test_like 'foo%'
-- Query 1:
SQL Server Execution Times:
CPU time = 0 ms, elapsed time = 1 ms.
-- Query 2:
SQL Server Execution Times:
CPU time = 47 ms, elapsed time = 40 ms.

I'm developing a web app using VS2005. I have a webpage with panel containing a gridview populated by a SQLdatasource. The SQLdatasource in turn is populated by a stored procedure that can take up to 5 parameters. The user types in up to 5 separate words (searchterms) in a text box which are then parsed and passed to the stored proc in the datasource which performs a fulltext search. The gridview then becomes visible. My problem is that unless the user types in 5 searchterms (no less), the gridview returns zero rows. 5 searchterms returns the proper results. Somehow, I need to be able to pass in null or empty values for unneeded parameters.
I've tested the stored procedure in Query Analyzer and from within the SQLdatasource configuration (using Test Query) using 0 up to 5 parameters and it works fine, so that's not my problem. Here's the code that runs after the user types in their search term(s) and presses a button:Public Sub FTSearch_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Handles btnFullText.Command
Dim x As Integer
pnlFullText.Visible = Falsefiltertext = Replace(txtSearchTxt.Text, "'", "''")
If Not filtertext Is Nothing Then
filtertext = filtertext.Trim
Else
Return
End IfDim arrayString() As String = filtertext.Split(" ")
Dim length As Integer = arrayString.LengthFor x = 0 To (length - 1)
If Not arrayString(x) Is Nothing ThenSelect Case x
Case 0 : lblFTParm1.Text = arrayString(0)Case 1 : lblFTParm2.Text = arrayString(1)
Case 2 : lblFTParm3.Text = arrayString(2)Case 3 : lblFTParm4.Text = arrayString(3)
Case 4 : lblFTParm5.Text = arrayString(4)

I have a stored proc that I'd like to return an output param from. I'm using a SQLDataSource and invoking the Update method which calls the sproc.The proc looks like this currently:
ALTER proc [dbo].[k_sp_Load_IMIS_to_POP_x]@vcOutputMsg varchar(255) OUTPUT
AS
SET NOCOUNT ON ;
select @vcOutputMsg = 'asdf'
The code behind looks like this:protected void SqlDataSource1_Updated(object sender, SqlDataSourceStatusEventArgs e)
{
//handle error on return
string returnmessage = (string)e.Command.Parameters["@vcOutputMsg"].Value;
}
On the page source side, the params are defined declaratively:
<UpdateParameters>
<asp:Parameter Direction="ReturnValue" Name="RETURN_VALUE" Type="Int32" />
<asp:Parameter Direction="InputOutput" Name="vcOutputMsg" Type="String" />
</UpdateParameters>
When I run it, the code behind throws the following exception - "Unable to cast object of type 'System.DBNull' to type 'System.String'"
PLEASE HELP! What am I doing wrong? Is there a better way to get output from a stored proc?

hello,
i have a table in witch i store the favorites pictures for each user, like so:
FavID PictureID UserId (uniqueidentifer)
users can add a picture at favorites by clicking a button from the picture table ("Add to favorites")
i need a stored procedure witch uses two input params (userId and PictureID), witch should return 1 if the relations between the PictureID and UserId already exists in the table(avoid having same relation again) or 0 if not (and i'll use that result to make the button enabled or disabled)
how can i do that?
if you didn't understood, please tell me
thanks

I have a stored proc that will insert a new row into a table
with the values of the parameters you pass in. I need it to
return the value of the ID that's generated by an Identity
column once the row has been written and that value has
been generated. If I just do a SELECT Max(), I could
accidentally grab a row written by someone else, right?
My current sp looks like this:
CREATE PROCEDURE sp_SaveNewLabel
-- @LabelID int output
@LabelType int
, @Logo int
, @Field01 char(30)
AS
INSERT INTO tbLabel
(LabelType
, Logo
, Field01)
VALUES
(@LabelType
, @Logo
, @PrintCC
, @Field01)
How do I grab the new LabelID (the column is int, Identity) and return
it from the stored proc. Any help would be greatly appreciated...
Zack
