Assigning A Select Value To Each Row Of A Dataset
Oct 4, 2007
I have the following problem:
in a data flow, if inserting new records, there are columns that take some default values. These default values are kept in a table in case the user wants to change them some day. Def. values could not be assigned at a table level because there's another dataflow that populates the same table, but the rules for the default values are different.
Since I want to extract these values only if there is at least one new row, I'm not fond of the idea to use Execute SQL Task (to save the default values in a variable) before the actual Data Flow. What are my options in getting these values in a Data Flow right before inserting? Thank you for the help.

Group,Is there a way to assign nullability on a column when using a select into?I've tried some of the usual things like coalsce, isnull, and cast. Sincethe new table gets definition from the source table or can be somewhatadjusted with cast is there a way to cast a not null? In the example belowhow can I select into causing tableone_new..col2 to be not null. Wetypically must use an alter statement after the select into but this seemsinefficient.Thanks,Raycreate table tableone (col1 int not null,col2 int )goinsert tableone values (1, 1)insert tableone values (2, 2)insert tableone values (3, 3)goselectcol1,col2into tableone_newfrom tableonegoexec sp_help tableone_newgodrop table tableonegodrop table tableone_newgo

The problem I'm having is described below all this code.---------------------------------------------------------My content page has a SqlDataSource: <asp:SqlDataSource ID="sqlGetUserInfo" runat="server"
ConnectionString="<%$ ConnectionStrings:RemoteNotes_DataConnectionString %>" SelectCommand="SELECT [UserFirstName], [UserLastName] FROM [Users] WHERE ([UserGUID] = @UserGUID)"
onselecting="sqlGetUserInfo_Selecting"> <SelectParameters> <asp:Parameter Name="UserGUID" Type="String" /> </SelectParameters> </asp:SqlDataSource> -----------------------------------------------------Inside my OnSelecting event, I have: protected void sqlGetUserInfo_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { sqlGetUserInfo.SelectParameters["UserGUID"].DefaultValue = Membership.GetUser().ProviderUserKey.ToString(); } ---------------------------------------------------------------------And, inside my Page_Load, the relevant code is: //String strUserFirstName = ((DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty)).Table.Rows[0]["UserFirstName"].ToString();
DataView dvUserDetails = (DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty);
if ((dvUserDetails != null) && (dvUserDetails.Count > 0)) { DataRow drUserInfo = dvUserDetails.Table.Rows[0]; lblHelloMessage.Text = "Hello, " + drUserInfo["UserFirstName"].ToString() + ((drUserInfo["UserLastName"].ToString() == "") ? "" : " " + drUserInfo["UserLastName"].ToString()); } ---------------------Now, here's the problem. My "if" statement is never executing because "dvUserDetails" is null. However, when I break the execution and put awatch on the actual Select() statement, it shows a DataView with the correct return rows! You can see the commented line where I tried tobypass the DataView thing (just as a test), but I get an object reference is null error.The weird thing is that it was working fine one minute, then started getting "funky" (working, then not, then working, then not), and now it just doesn't work at all. All thiswithout me changing one bit of my code because I was checking out some UI flow and stopping and restarting the application. I've tracked downthe temporary files directory the localhost web server runs from, deleted all those files, and cleaned my solution. I've even triedrebooting, and nothing seems to make it work again.My relevant specs are VS2008 9.0.21022.8 RTM on Vista Enterprise x64.

Hi,
I think I'm just braindead or simply thick...since this shouldn't be that hard, but I'm stumped right now.
So, I'm trying to retrieve from a table, with a sql stored procedure with the sql like
"select height, width, depth from products where id=@idinput"
OK, so this part is easy, but if I wanted to say, return this to my code and assign height to a variable Ht, width to Wd and depth to Dp, how could I do that?
This is what I've got so far...
[code]
cmdSelect = New SqlCommand( "GetProd", connstr )
cmdSelect.CommandType = CommandType.StoredProcedure
dbcon.Open()
dbcon.Close()
[/code]
The main prob is just what to connect this record to in order to access the individual fields.
Thx :)

I have a report that uses different datasets based on the year selected by a user.
I have a year_id parameter that sets a report variable named dataset_chosen. I have varified that these are working correctly together.
I have attempted populating table cell data to display from the chosen dataset. As yet to no avail.
How could I display data from the dataset a user selects via the year_id options?

I have an Execute SQL Task that executes "select count(*) as Row_Count from xyztable" from an Oracle Server. I'm trying to assign the result to a variable. However when I try to execute I get an error:
[Execute SQL Task] Error: An error occurred while assigning a value to variable "RowCount": "Unsupported data type on result set binding Row_Count.".
Which data type should I use for the variable, RowCount? I've tried Int16, Int32, Int64.
Thanks!

Can I do the way below?

I'm using the designer to create/modify strongly typed datasets. I have one select statement that I'm having considerable trouble with. The user selects search parameters from a form. These search parameters are used to filter the data sent to a gridview control. Three of these parameters are almost enough to make me abandon the dataset in this case.The first two are minimum and maximum age. I have a birth date field, but not an age field - ages have a habit of changing without user intervention <grin> and can be calculated. In ASP I'd do something like this:strSQL = "SELECT [DATE OF BIRTH], [FIRST NAME], [LAST NAME], [STATE], [MALE OR FEMALE] FROM members WHERE (DateDiff(yyyy, [DATE OF BIRTH], '" & date & "') >= " & strLowerAge & ") AND (DateDiff(yyyy, [DATE OF BIRTH], '" & date & "') <= " & strUpperAge & ")" I can't figure out how to get datediff working in the designer much less testing against upper and lower age limits.The third parameter is astrological sign. Again, I calculate it based on the birth date. I don't have a field for it. I could, but I would have to modify all the pages that add or edit records to the database to insure all the records that have birth dates also have the right sign. I'm leaning in that direction, but is it possible to accept a sign as a parameter and calculate, based on the birth date, which records qualify? I need to get the age issue fixed. The sign is a nice to have, since I can do it another way if I have to. BTW: I did decide to abandon the dataset in favor of a SqlDataSource control. This allowed me to build my select string in the code behind the way I would have in ASP. This resulted in paging and sorting not working properly. Sorting would be nice, paging is necessary. I'm pretty sure going back to the dataset or using a stored procedure would fix the paging problem, and I've yet to work with stored procedures (it's on my list of things to learn). Any comments or feedback on this would be avidly read and appreciated.Diane

Hello,
I have been reading about how you shouldn't build dynamic SQL statements (see TextBox1.Text in line 3) and should use parameters instead, but I haven't yet found how to create a SELECT statement with a parameter that fills a dataset. If anyone can show me the correct way of doing this I would appreciate it so I can add it to my code snippets for proper coding practices. Thanks in advance for any assistance.
string strConnectionString = ConfigurationManager.ConnectionStrings["sqlConnectionString"].ConnectionString;
SqlConnection myConnection = new SqlConnection(strConnectionString);
-> string sqlSelect = "select * from customers where city = " + "'" + TextBox1.Text + "'";
SqlDataAdapter da = new SqlDataAdapter(sqlSelect, myConnection);
DataSet ds = new DataSet();
myConnection.Open();
da.Fill(ds, "myDataset");
myConnection.Close();

Hi,
OK, trying to return the results from two SQL statements into a DataSet using SqlDataAdapter. The SELECT statements query the same table but are looking for different records based on the date that the records were inserted - the 1st query looks for records fro the current month and the 2nd one looks at the same records but for the previous month. The goal is to be able to do some math within a repeater and get the difference between the two records.
Sounds easy enough and it has worked for me in different variations of the same idea but not this time - here's the code:
Protected Sub buildPartsReport(ByVal varHC) objConn.Open() sSQL = "SELECT ap.id,item_model,item_sn,aircraft_id,item_loc=item_type+ ' on ' +(SELECT tnum FROM T_Aircraft WHERE id=aircraft_id),apt.tot_time As endTimes,apt.tot_cycles as endCycles FROM T_Aircraft_Parts ap, T_Aircraft_Parts_Totals apt WHERE ap.id=apt.part_id AND report_date= '" & rD & "' AND item_type LIKE 'engine%';SELECT ap.id,apt.part_id,apt.tot_time as startTimes,apt.tot_cycles as startCycles FROM T_Aircraft_Parts ap, T_Aircraft_Parts_Totals apt WHERE ap.id=apt.part_id AND report_date= '" & oldRD & "' AND item_type LIKE 'engine%'" Dim objCommand As New SqlDataAdapter(sSQL, objConn) DS = New DataSet() objCommand.Fill(DS) Repeater1.DataSource = DS Repeater1.DataBind() DS.Dispose() objCommand.Dispose() objConn.Close() End Sub
Sorry if it wrapped a bit. The "rD" and "oldRD" are the variables for the date ranges (currently set to static numbers for testing). I'm getting the following error when I run this on an ASP.Net page:
System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'startTimes'.
The code works fine when run via the Query Tool on the SQL server (SQL 2005 Std) though it produces two distinct "tables" which I'm guessing is the problem. I've tried variations on the code including creating a 2nd dataset and then attempting a merge (no joy) and I've tried the ".TableName" route but it complains about trying to add the tablename twice.
Thoughts? I need to get this to work - it is part of a reporting component for an application that I'm developing and I'm stuck. Thanks as always...

I have a remote report ...
I need to call one of two stored procedures depending on which parameters were passed to the report. (Both stored procedures return the same fields.)
Does SQL Reporting Services allow you to switch the dataset or stored procedure name dynamically? If so, where do I put the logic? Right now I have it working with one stored procedure.
I'm thinking that I should just make one stored procedure that takes all parameters and calls one of the other two stored procedures. Do I have any options besides this?
Thanks in advance!

If I want to select a value from a certain row in my Dataset.
I have a dataset called labels in my Report. in this data set I have diffrent row and in each row I have a label with an
ID. For example:
ID Â Â Â Â Â Â Â Â Â Â Â Â Text
TEXT0001 Â Â Â Â Â Â Hi
TEXT0002 Â Â Â Â Â Â Good Morning
TEXT0003 Â Â Â Â Â Â Good bye
Is this is the right way to get the second row?

I am working on a company sign out sheet for our Intranet. The application accesses a sql database. I tried using a datareader as well as a dataset to access a small piece of information regarding the group that each employee belongs to in the company. My last attempt was to assign the value to the text property of a text box and evaluate the text from the text box with the Select Case but that did not work either.The application is supposed to generate an email to our receptionist as well as to the group technical assistant responsible for each group according to the value that is passed into the Select Case statement. With the datareader as well as the dataset and even now with creating a text box and accessing the text property, I was able to assign the group value to a variable (I can see the value in the subject of the email), but when the variable is supposed to be evaluated by the select case statement it skips right through all of the cases to case else and uses only the receptionist's address in the email as if it doesn't even see the value of the variable. I have searched for a possible answer to the problem I am but so far have had no luck. Any ideas? I included the part of the code that I am having trouble with: '********************************************************************************************' New DataSet is created to determine the group the employee belongs to so that the appropriate' group technical assistant is emailed when employee signs out'******************************************************************************************** ' declare variablesDim sqlGroup As String ' string variable to store sql statement for datasetDim BLGroup As String ' string variable to store the bl group of the employeeDim emailAddress As String ' string variable to store resulting email address Dim groupDS As DataSet ' dataset variableDim groupAdapter As SqlDataAdapter ' sql data adapter variable' sql statement to access group value from the databasesqlGroup = "SELECT BLGroup FROM BLGroupsView WHERE (RTRIM(fname) + ' ' + LTRIM(lname)='" & employee & "')" ' repopen the connection (leftover from working with the datareader)Connection.Open()' create new SqlDataAdapter applying sql statement and connectiongroupAdapter = New SqlDataAdapter(sqlGroup, Connection)' create new dataset groupDS = New DataSet()' populate the datasetgroupAdapter.Fill(groupDS, "BLGroupsView") ' get the value stored in the BLGroup column (only one row is returned at a time) BLGroup = groupDS!BLGroup' Create GroupTextBox TextBox control.Dim GroupTextBox As New TextBox()' Set options for the UserTextBox TextBox control.GroupTextBox.ID = "GroupTextBox"GroupTextBox.Visible = "False"GroupTextBox.Text = BLGroup' just trying anything with this next line, even when i didn't set this the select case statement did not seem to see the value returned by the variableGroupTextBox.runat = "server" ' use a select case statement to evaluate the value of the group (didn't work when I passed in the BLGroup variable eitherSelect Case GroupTextBox.TextCase "bh"emailAddress = "receptionist@myaddress.com; bhassistant@myaddress.com"Case "env"emailAddress = "receptionist@myaddress.com; envassistant@myaddress.com"Case "sw"emailAddress = "receptionist@myaddress.com; swassistant@myaddress.com"Case "fac"emailAddress = "receptionist@myaddress.com; facassistant@myaddress.com"Case "www"emailAddress = "receptionist@myaddress.com; wwwassistant@myaddress.com"Case ElseemailAddress = "receptionist@myaddress.com"End Select '*************************************************************************************************' set new message objectDim myMessage As System.Web.Mail.MailMessage = New System.Web.Mail.MailMessage()'**********************************************************' set message properties'********************************************************** myMessage.From = "me@myaddress.com"myMessage.To = emailAddressmyMessage.Subject = employee & " Signing Out at " & TimeOut.Text & " " & BLGroupmyMessage.Body = employee & " Signing Out at " & TimeOut.Text & " for " & Destination.Text & " will potentially return at " & EstTimeIn.Text'***********************************************************' set smtp server namesmtpMail.SmtpServer = "mailserver1"' send email using smtpsmtpMail.Send(myMessage) It sends the message and returns the BLGroup value everytime but only sends to the receptionist.

Hi all,
I have a SP that return a dataset and I was thinking to execute that SP inside of other SP then catch the dataset to put into a variable or put into a temp table. What I know is you can not use recordset on output and input parameter in SP correct me if im wrong. I'm just wondering if I there is a work around in this scenario.
Thanks and have a nice day to all.

I have 4 sets of select queries under 1 stored proc, now on the report calling the stored proc via dataset. when i run the dataset the only first set of the select query related fields appearing under the dataset.
But on the back end sql server, if i execute the same stored proc, i get 4 resultsets in one single executioln.
i am not seeing the remaingin 3 resultsets, on the reports dataset.
Is it possible on the reports or not.
In the asp.net project i was able to use that kind of stored procedures whcih has multiple select statements in 1 procedure., i use to refer 0,1,2,3 tables under a dataset.
Thank you all very much for the information.

I have a stored proc that I'm using to run a report. It works fine, but currently I'm using a parameter that is a single selection from a dropdown. I'd like to use multi select, but have not been able to get it to work.
In the data tab I'm currently using "text" for command type and :
Code Snippet
declare @sql nvarchar(2000)
set @sql = '
EXEC [Monitor] '' + @p_OfferStatus + '''
exec sp_executesql @sql, N'@p_OfferStatus VARCHAR(100)', @p_OfferStatus = @p_OfferStatus
when I run this in the data tab, it works fine, returning data, but when I try to preview it it tells me there are syntax errors. Anyone know the correct way to use multi selects with stored procs?

hi all
Any day, another question. I love you guys.
I want to select a subset of data from a dataset returned by either another subquery or a union.
e.g. this is how i would do it in oracle, but i have no idea how this can be done in mssql or whether it's possible at all.
select * from
(
select col1, col2, col3 from table1
union
select col1, col2, col3 from table 2
)
where col1 = 'blah'
in essence oracle treats the data returned by the subquery as a table that it would select from.
how would i do the same in mssql?
thank you
James :)

Hi there,
I have a MS Access database (mdb) containing the following tables:
Crime
Criminal
CrimeCommitted
Hideout
CriminalType
The Criminal table contains information about each criminal and the CrimeCommitted table contains information about the specific crimes. I've written the following query to return only the latest crime committed by each criminal:
Code Snippet
SELECT Criminal.CriminalID, Criminal.Firstname, Criminal.Lastname, Criminal.Nickname, Criminal.Gender, Criminal.DOB, Criminal.Eyes, Criminal.Complexion, Criminal.Weight, Criminal.Height, Criminal.Build, Criminal.Scars, Criminal.Occupation, Criminal.CrimeOrgID, Criminal.IQ, Criminal.Hideout, Criminal.CriminalType, Max(CrimeComitted.Date) AS Last_Crime_Comitted
FROM Criminal INNER JOIN CrimeComitted ON Criminal.CriminalID=CrimeComitted.CriminalID
GROUP BY Criminal.CriminalID, Criminal.Firstname, Criminal.Lastname, Criminal.Nickname, Criminal.Gender, Criminal.DOB, Criminal.Eyes, Criminal.Complexion, Criminal.Weight, Criminal.Height, Criminal.Build, Criminal.Scars, Criminal.Occupation, Criminal.CrimeOrgID, Criminal.IQ, Criminal.Hideout, Criminal.CriminalType;
This query works fine for obtaining the Criminal table data, but once i've include CrimeCommitted.Country in the SELECT statement, the data returned contained all the crimes committed by each criminal (i just need the latest crime).
The query doesn't work when another table, other than Criminal, is selected. How can i obtain the columns in the CrimeCommitted table in this query?

I've only been doing sql 2005 for a couple of months with minimal training so there's a lot I don't know.
What I'm trying to do is load a nested table (industry & customer totals) based on a value from the table it's nested in.
This is the relationship of the data.
I have at the highest group, an industry code, then a customer, then the part and then the fiscal year.
What I'm trying to accomplish is to get a group total (footer) for the (1) industry code and (2) the customer code. This footer would contain the fiscal years (ascending) and their monthly totals. I would like to take the industry code from table one and pass it to the select statement in the dataset that feeds the nested table. I've read this is not possible to load a dataset field into a parm but I've seen where some people know how to work around this. If you reply, please explain in simple terms. Thanks!

I have a report with multiple datasets, the first of which pulls in data based on user entered parameters (sales date range and property use codes). Dataset1 pulls property id's and other sales data from a table (2014_COST) based on the user's parameters. I have set up another table (AUDITS) that I would like to use in dataset6. This table has 3 columns (Property ID's, Sales Price and Sales Date). I would like for dataset6 to pull the Property ID's that are NOT contained in the results from dataset1. In other words, I'd like the results of dataset6 to show me the property id's that are contained in the AUDITS table but which are not being pulled into dataset1. Both tables are in the same database.

I have a small number of rows in a dataset, Table 1. There is a CLOB on a large dataset, Table 2. They join on a PK. I would like to retrieve this CLOB and add it to the data flow for Table1. In short I want to emulate the following:
Table 1:Â Small table without CLOB, 10 rows.Â
Table 2: Large table with CLOB, 10,000,000 rows
select CLOB
from table2
where pk = (select pk from table1)
I want this to return the CLOBs for the small number of rows in Table 1. The PK is indexed obviously so it should be a fast look up.
Table 1 and Table 2 live on different Oracle databases. How do I perform this operation efficiently in SSIS? It seems the Lookup and Merge Join wont do this.

Hi there !
Thanks for taking the time to read this thread.
I don't know whether anyone has this problem, but I am definitely not using the right keywords to search for a thread.
My situation is this...
I have a dataset that has values to fill cells to multiple tables in a report.
However, I only want to select specific data from the dataset to fill textboxes and others.
I cannot change the stored procedure, but the sample of the data is shown below:-
Row Stat Val
0 dtRpt1 02/01/2005
1 Value1 1
2 Value2 2000
3 dtMailSent 02/28/2005
4 Value3 0
5 Value4 5
6 Value5 658
I know it looks weird, but the row really represents which "row" or textbox is it to fill with the Val. The Stat Column is just a way to make sure that I am filling the right values.
so my new report would have multiple tables to denote different categories.
In my first table, I tried putting the cells as follows:-
(expressions are highlighted in italics and bold)
TextBox1 =IIF(Fields!Row.Value =0, Fields!Val.Value,"")
Table1
Column1
DetailRow1 =IIF(Fields!Row.Value =1, Fields!Val.Value,"")
DetailRow2 =IIF(Fields!Row.Value =2, Fields!Val.Value,"")
Table2
Column1
DetailRow1 =IIF(Fields!Row.Value =3, Fields!Val.Value,"")
DetailRow2 =IIF(Fields!Row.Value =4, Fields!Val.Value,"")
DetailRow3 =IIF(Fields!Row.Value =5, Fields!Val.Value,"")
DetailRow4 =IIF(Fields!Row.Value =6, Fields!Val.Value,"")
I only expect this report to print out one page holding the previous values.
However, it ended up printing like this
----------------------------------------------------------
Table1
Column1
DetailRow1 1
DetailRow2
Column1
DetailRow1
DetailRow2 2000
Table2
Column1
DetailRow1 02/28/2005
DetailRow2
DetailRow3
DetailRow4
Table2
Column1
DetailRow1
DetailRow2 0
DetailRow3
DetailRow4
Table2
Column1
DetailRow1
DetailRow2
DetailRow3 5
DetailRow4
Table2
Column1
DetailRow1
DetailRow2
DetailRow3
DetailRow4 658
------------------------------------------------------
I tried putting it into the headerrows instead of DetailRows, and it ended up printing the last value.
Is there anyway to do this ? print all the values out in one table ? I tried using textboxes, but I think I got my expression wrong.
Is this the correct expression ?
=IIF((Fields!Row.Value,"Dataset") =1, (Fields!Val.value, "Dataset"), "")
and it give me an error
The value expression for the textbox €˜textbox5€™ contains an error: [BC30455] Argument not specified for parameter 'FalsePart' of 'Public Function IIf(Expression As Boolean, TruePart As Object, FalsePart As Object) As Object'.
Appreciate any advice or suggestion for this scenario !
Thanks!

Any help is appreciated.

Hi,
I have two datasets in my report, D1 and D2.
D1 is a list of classes with classid and title
D2 is a list of data. each row in D2 has a classid. D2 may or may not have all the classids in D1. all classids in D2 must be in D1.
I want to show fields in D2 and group the data with classids in D1 and show every group as a seperate table. If no data in D2 is available for a classid, It shows a empty table.
Is there any way to do this in RS2005?

Col1...Col2
1.....A
2....B
Table B
Col3...Col4
1.....X
2....Y
TableC
Col1...Col3....Col5...Coln
1........1...........H....Y.
A&B serve as the parent table for C. A&B are the dimension tables and C is the fact table. How do I assign the PK and FK in EM?
Thanks

Consider the following:
Sub regUser(s as Object, e as EventArgs)
If IsValid Then
Dim stuTable as String
Dim connStr as String
stuTable = "mytable"
connStr = "myConnectionInfo"
'check to see that student num is in the db
Dim connect as SqlConnection
Dim strSelect as String
Dim cmdSelect as SqlCommand
Dim strDbResult as SqlDataReader
connect = New SqlConnection(connStr)
strSelect = "SELECT stu_num, stu_fname, stu_lname FROM " + stuTable + " WHERE stu_num=@stuNum"
cmdSelect = New SqlCommand(strSelect,connect)
cmdSelect.Parameters.Add("@stuNum", txtStdNum.text)
connect.Open()
strDbResult = cmdSelect.ExecuteReader()
Dim stuFName as String
Dim stuLName as String
Dim stuEmail as String
Dim strRandom as String
Dim strPassword as String
Dim i as Integer
Dim charIndex as String
Dim stuMailMessage as MailMessage
Dim strHTMLBody as String
'declare stuFname, stuLname, stuEmail
stuFName = strDbResult("stu_fname")
stuLName = strDbResult("stu_lname")
stuEmail = txtStdEmail.text
'more code follows ....
In my DB I have a table with the columns stu_num, stu_fname and stu_lname. Each of these columns contains rows with data. However, the proceeding code gives me this error: Invalid attempt to read when no data is present (line 58 --> stuFName = strDbResult("stu_fname") ).
What am I doing wrong here? How do I assign the stu_fname in the DB to the page level variable stuFName?
As a little aside how do I say "If no record was found matching stuNum Then" ... ??
Sorry, I'm a .NET beginner ...

Hi ,
I have a typical scenario here where I am trying to assign a variable a value using another variable, for that I am using two execute SQL task , the fisrt one assigns the first variable a value and then the second one uses the first variable to evaluate and then assigns a value to another variable. The first execute sql task works fine , however the second one fails with the following error
"failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_I4)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. "
Here is the query I am using to assign the value in my second execute sql task
select (CASE
WHEN Sum(col1) <> 0 AND ? = 'M' THEN 'M'
WHEN Sum(col2) <> 0 AND ? >= 'T' THEN 'T'
WHEN Sum(col3) <> 0 AND ? >= 'R' THEN 'R'
ELSE 'S'
END) as Current
FROM dbo.TABLE1
I am passing the variable by mapping the parameters and then assigning the value using a single row result set.
Can someone please tell me where am I going wrong?
Thanks
