SqlCommand comm = new SqlCommand(sql, conn);
Now if i want to set the Pos to a variable where i can call at another part of my program, how do i do that?
Hi!
Is it possible to set a query result (scalar) to scalar variable. I would like to set a qery result (SELECT COUNT(*) FROM MyTable) to a scalar variable:
DECLARE @temp int
SET @temp = query result...
Is it possible? I couldn't find the way to do that...
I need to send the result of a procedure to an update statement.Basically updating the column of one table with the result of aquery in a stored procedure. It only returns one value, if it didnt Icould see why it would not work, but it only returns a count.Lets say I have a sproc like so:create proc sp_countclients@datecreated datetimeasset nocount onselect count(clientid) as countfrom clientstablewhere datecreated > @datecreatedThen, I want to update another table with that value:Declare @dc datetimeset @dc = '2003-09-30'update anothertableset ClientCount = (exec sp_countclients @dc) -- this line errorswhere id_ = @@identityOR, I could try this, but still gives me error:declare @c intset @c = exec sp_countclients @dcWhat should I do?Thanks in advance!Greg

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!
I have a question regarding Execute SQL Task as I combined one statement like select count(*) from destination table, and insert into error table (source count, error count, destination count) values (?,?,?).
If I use two Execute SQL Task, it should work. I was wondering that is it possible to combine select and insert into one Execute SQL Task direct input. How to approch this?

View 1 Replies View RelatedHello,
I have a report which displays a customers invoice, in both the companys local currency, and the customers local currency.
The report language is "English (United Kingdom)"
The fields showing customers currency language setting is set to something else, i.e. "France (French)" to display the Euro currency.
The application handles 34 currencies, the query returns the language string, ("France (French)"), to allow the report to bind its language setting to the querys output.
However, it doesn't work, a normal textbox will display the correct country name string, but Reporting Services cannot bind the language setting to a query result. So I also tried setting it as a report parameter, but no joy either (all currencys revert to USD).
I'm using =First(Fields!curFormat.Value, "myDataSet") to bind the 'language' setting, the result of this expression returns "France (French)", which is a valid option for this language setting, as it's in the drop down list.
Rather than create 34 seperate reports for each currency, are there any suggestions on how to bind a fields language setting to a query result?
sry im an idiotbut how do u take like "SELECTbla FROM blar WHERE blam=blfda" and make the thing it "selects" into a variable thnx

hi !
I am trying to set the variables value through Execute SQL task and create directory through the FileSystemTask by setting the user variable as source. The User variable has the Directory path to create the directory, but when i set the source as the user variable it complains that its value is empty.
Execute SQL TAsk happens to work correctly when i check the watch window the user variable is set correctly . but value is not setting in the SSIS/Variable window Value.
What is wrong an what method should i use to set the variables value to create directory.

Hi, folks. As part of a larger bunch of code, I am trying to validate some user form input against a database...I've been picking apart code samples and have the following (currently not yet working) code to show for it. I find tons of complex examples out there RE the data controls, and I have those working. But I can't find any examples of just pulling a single record from a DB, sticking it in a variable, and then checking against that variable to get a boolean response. Anyway, here is the code. I am trying to check that a password field filled by the user matches the value located in the DB. I am not married to this code; if someone suggests a better way to do it rather than using a custom validator control, that's fine too:BEGIN CODE SNIPvoid Page_Load(object sender, EventArgs e)
{
Page.Validate();
SqlDataSource1.SelectCommand = "SELECT Password FROM aspnet_Membership WHERE aspnet_Membership.Email='" + emailID.Text + "'";
}
private void CustomValidator1_ServerValidate(object source, System.Web.UI.WebControls.ServerValidateEventArgs args)
{
//between this and the next comment is where I have to get the DB Password field value for the current record
SqlCommand command = new SqlCommand("SELECT Password FROM aspnet_Membership WHERE aspnet_Membership.Email='" + emailID.Text + "'");
command.CommandType = CommandType.StoredProcedure;
sqlConnection.Open();
reader=command.ExecuteReader();
string currentPasswordDb = reader.IsDBNull(reader.GetString("Password"))? null: reader["Password"].ToString();
args.IsValid = false; // Assume False
{
// Compare db entry against user's entry
if (currentPasswordDb == currentPassword.Text)
{
args.IsValid = true;
}
}
} END CODE SNIP The code above give me the following at runtime:Line 14: SqlCommand command = new SqlCommand("SELECT Password FROM aspnet_Membership WHERE aspnet_Membership.Email='" + emailID.Text + "'");Line 15: command.CommandType = CommandType.StoredProcedure;Line 16: sqlConnection.Open();Line 17: reader=command.ExecuteReader();Line 18: string currentPasswordDb = reader.IsDBNull(reader.GetString("Password"))? null: reader["Password"].ToString();Although I'm sure it won't be the last. I'm a former ASP classic developer, moving to c# and .Net. Any ideas?
Hi,

The For Loop will execute a stored procedure that passes a variable each time it loops. I need to set this variable, @FiscalWeek, equal to the variable @Counter. So the first time it loops, the counter will be 1, and the Fiscal Year would be set to 1. The next time it would be two, and so forth. Can I do this in the Expressions section of the For Loop? If so,
what would the property be?
InitExpression @Counter =0
EvalExpression @Counter == @CurFiscalWeek
AssignExpression @Counter = @Counter + 1

I want to be able to have a single select statment:
SELECT TOP 1 Call.JobNum, Call.CallID, Call.Company, Call.LastCallTime
FROM ClientJob INNER JOIN Client ON ClientJob.ClientID = Client.ClientID
INNER JOIN Call INNER JOIN Login ON Call.JobNum = Login.JobNum ON ClientJob.JobNum = Login.JobNum
WHERE (Login.LoginID = 3) AND (Call.Status = 0) AND (DATEDIFF(hh, Call.LastCallTime, getdate()) > 10)
ORDER BY Call.CallID
but with this select statment I also want to set a variable:
declare @variable int
SELECT TOP 1 Call.JobNum, @variable = Call.CallID, Call.Company, Call.LastCallTime
FROM ClientJob INNER JOIN Client ON ClientJob.ClientID = Client.ClientID
INNER JOIN Call INNER JOIN Login ON Call.JobNum = Login.JobNum ON ClientJob.JobNum = Login.JobNum
WHERE (Login.LoginID = 3) AND (Call.Status = 0) AND (DATEDIFF(hh, Call.LastCallTime, getdate()) > 10)
ORDER BY Call.CallID
Now SQL Server does not like this, can not set a variable in a multiple select statment. I NEED to do this all in one step if possible. Any suggestions?

Why does this not work?
declare @ret varchar(50)
DECLARE @X SQL_VARIANT
set @X=10
SET @ret=select SQL_VARIANT_PROPERTY(@X,'BaseType')
Just trying to assign the SQL_VARIANT_PROPERTY return value to @ret and it issues an error: Implicit conversion from data type sql_variant to varchar is not allowed. Use the CONVERT function to run this query.
But I don't want to convert I just want to assign the result to the variable.
what's confusding is that you can do this:
if(select SQL_VARIANT_PROPERTY(@X,'BaseType'))='int'
So I assume I should b able to do the above.

Hi,I am having problems setting the value of a variable in a SQL Stringthat I have to create dynamically in my procedure. The code that Icurrently have is as follows:set @sqlStatement='Set @compare_string=' + '(Select ' +@group_column_list_mod + ' from ' + @Tbl_Name + '_Sorted' + ' whereIdentity_Column=' + ltrim(rtrim(str(@loop_counter))) + ')'exec(@sqlStatement)The error message that I get is as follows:Must declare the variable '@compare_string'.Here @compare_string has already been declared in the procedure and Idon't have a problem using the variable anywhere else but this SQLStatement (when called using the EXEC function).I am not sure why SQL Server can't see the variable declared when usedin a string in conjunction with EXEC. Is this a syntax issue? Any helpon this issue would be greatly appreciated!Thanks in advance.

If this is the syntax to set a property in a package using dtexec:

What is the syntax for setting a global variable in the package?

I'm in the process of creating a series of packages to do the ETL for a datawarehouse. As such, I've got quite a few DataFlow tasks scattered through them.
The problem I'm coming across is where the disk that the temp files (created during the processing) are put on is short of space (when compared to some of the data sets I'm copying around and noting that it's the System disk, not the "Data Drive").
To get around this, I found number of article scattered around that suggested using the BufferTempStoragePath property of the DataFlow tasks to redirect the temp files to somewhere else. This works fine for the tasks that I hard-code the new directory.
Noting the number of these tasks that I want to redirect, and also that the Dev environment will be different to the Production environment (and I have no control over the drive letters, paths, etc, in Prod), it was suggested that a package variable be created, assigned to the property and then said variable could be exposed via the Package Configuration file.
That's great as far as it goes, but I just cannot, for some reason, make it work.
The xml in the config file is:
<Configuration ConfiguredType="Property" Path="Package.Variables[::BufferTempStoragePathValue].Properties[Value]" ValueType="String">
<ConfiguredValue>D:Temp</ConfiguredValue>
</Configuration>
The property in the DataFlow task is then set to: @BufferTempStoragePathValue.
When the package is executed, it logs the error message "The buffer manager cannot create a temporary storage file on any path in the BufferTempStoragePath property. There is an incorrect file name or no permission."
My question for the group is two-fold: 1) what am I doing wrong in the setup of the property/variable, and 2) what are the security permissions that are required for the (new) folder.
It's got to be something obvious, I just can't see what!
Many thanks for your assistance.
Cheers,
Mike
Hi,
im using a Foreach ADO Enumerator in my SSIS Package, which iterate on a DataSet from a SQL Task.
I use the "Variable Mappings" on my Foreach Loop to retrieve the values into User-variables. But what i need is a way to combine a value from the DataSet with a User-variable and assign this new value to a new User-variable.
Anybody tried something like this?

I want to modify that variable in such a way that if no value is set for that variable then use system date else use date in varaiable.

ok now i have this problem. I need to make a query that return one single data. I need to store this data in a variable. Something like that:
DECLARE @A VARCHAR(50)
@A=SELECT mycolumn FROM mytable WHERE mycolumn = 'Something'
There is a form to do it?
Thanks Friends
i need to know how many rows are in a certain table and store this value in a variable in order to process this variable later in the package. of course i can build a data flow task within a row count component but as far as i understand it's necessary to read all data from a data source in order to use the row count component. now the question is if it's possible to use a sql task in the control flow and put a select count(*) statement within the task and then write the result of this select statement into a variable. shouldn't that be much more faster than using a whole dataflow for this problem?
View 1 Replies View RelatedIn a stored procedure that I'm fixing, there is a problem with assigning variable values inside a loop. The proc is using dynamic SQL and if statements to build all these statements, but I'm having to add a new variable value to it that is throwing it out of whack.
This is the current structure:
SET @MktNbr = 10
WHILE @MktNbr < 90
BEGIN
DECLARE@sqlstmt varchar(1000)
SET @Market = '0' + CONVERT(char(2),@MktNbr)
SET @sqlstmt = 'SELECT (columns)
INTO dbo.table' + @Market + '
FROM #table
WHERE marketcode = ''' + @Market + '''
IF @MktNbr = 50
BEGIN
SET @MktNbr = 51
END
ELSE
IF @MktNbr = 51
BEGIN
SET @MktNbr = 52
END
ELSE
IF @MktNbr = 52
BEGIN
SET @MktNbr = 55
END
ELSE
IF @MktNbr = 55
BEGIN
SET @MktNbr = 60
END
ELSE
BEGIN
SET @MktNbr = @MktNbr + 10
END
EXEC (@sqlstmt)
END
I'm probably having a blonde moment, but I'm trying to replace the if statements with this:
SET @MktNbr =
CASE
WHEN @MktNbr = 10 THEN 20
WHEN @MktNbr = 20 THEN 30
WHEN @MktNbr = 30 THEN 40
WHEN @MktNbr = 40 THEN 50
WHEN @MktNbr = 50 THEN 51
WHEN @MktNbr = 51 THEN 52
WHEN @MktNbr = 52 THEN 55
WHEN @MktNbr = 55 THEN 60
WHEN @MktNbr = 60 THEN 70
WHEN @MktNbr = 70 THEN 80
WHEN @MktNbr = 80 THEN 81
ELSE @MktNbr END
Clearly it's wrong because the proc bombs every time with a duplicate table error.
It has been suggested to me that I should hold these market values in an external table. This sounds reasonable but I'm ashamed to admit that I don't know how I'd implement that. Can someone maybe give me a nudge in the right direction?
I would like to set up a subscription that has two date parameters, I would like the end_date to be today and the start_date to be (today - 1 Month). The interface does not seem to support expressions?
I saw some documentation that said to use defaults in the report but that does not help because I may want multiple subscriptions with different params like 1 person may want (today - 2 months) as the start date ...
Any help would be appreciated
Hello There:
I am running a data flow within a ForEach loop wherein I am computing a value called QuotaGap. When it is 0 I do not want any further execution of the loop. I am using a Conditional Transform within this dataflow that writes a record to a table only when the QuotaGap is NOT 0. However, I am unable to terminate the execution of the loop as I am still within the dataflow.
Now, the computation of the gap requires a value from another variable called NetPurchases. I tried using an ExecuteSQL task in the control flow but could not figure out how to pass the value of the variable NetPurchases into the select statement to compute the gap. For example, the select statement would read:
select (QuotaUpperLimit - ?) As QuotaGap from <<tablename>>
I tried setting the parameter as an input as well as an output and it did not work.
Then I tried passing the entire SQL as a string within a variable. This does not work either because in order to compute the math QuotaUpperLimit - NetPurchases, both variables need to be integers but then you cannot concatenate integres together, which is what we need to do to create the SQL.
The other reason I am going through these hoops I guess is that I have not figured out a way to set the value of a variable within a data flow. I compute the value for QuotaGap within the dataflow in a ForEach loop but I have no way to pass this result to a variable called QuotaGap without using an ExecuteSQL task or another ForEach Loop.
I have spent hours on this simple issue and so have given up and looking to the good friends in this forum for help.
If what I have stated is not clear please let me know and I will try to clarify things a bit.
Thanks!

Hello,
I am interested in what the simplest was to get a query result that will only ever have one result (ie One column, one row) into a variable. An ugly way is to use a cursor that simply fetches the first row but that seems to be a horrible way to do it and it has sometimes major drawbacks sometimes (mainly if I have to dynamically choose the table). Surely there is a better way?
What do you think? A simple example would be nice.
Cheers

Hi this is probably a very stupid question, but I still need to know.
How do I set the result of a 'SELECT' statement to a variable? I know I can use CURSOR, but I am certain the SELECT statement will return either 1 record or NULL. Can I use something else apart from CURSOR?
Is this possible as given below
declare @Qry as varchar(8000)
declare @Cnt as int
begin
set @Qry = 'select @Cnt=count(*) from ' + @TableName
exec @Qry
select @Cnt
end
But its not working....
can any one help me out in this.....
