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?
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.
I have looked thru several similar threads with errors like this, but have not found a resolution. I have a SQL Task that runs this query:
Code Snippet select NetRevenue = cast(sum(Base_Price + AL + MI + PO) as dec(10,2)) from Lancelot.DataWhse.dbo.GrossMarginDetail where tran_date_key <= ? + ' 23:59:59' and label_group <> 'X' and not (ar_ship_key in ('S999991','S998101''S998102')) and Document <> 'Cust Bal Debit Memo'
There is a parameter mapping of "User::LastSaturday" of type date. I also have a result set with a result set name of "0" with a variable name of "User::GrossMargin," which is defined as a double in the package. The task has a resultset type of Single row, and at the moment the answer that is returned is 66228637.10.
If I change the package variable to a type of string it of course works, but then I cannot do comparisons against it. I have step by step manually copied this from an existing DTSX, so I am baffled why this isn't working, and I'm ready to throw myself under a truck!
I also tried to bring it in as a string, then convert it in a script task, but I cannot figure out how to reference the input and output variables. I can't seem to find any relevant docs on how to do that...
If anyone has any ideas, I and my sanity would greatly appreciate it.
I am building a simple package that looks at the results of a sql query, prior to running the next step.
Basically Outline and settings
SQL task
Result Set: Full result set
SQL Source: Direct Input
SQL Statement: Select Count (*) FROM X
Parameter Mapping
Variable Name: User::C
Direction: Return Value
Data Type: Numeric
Parameter Name: NewParameterName
Result Set = NewResultName: User::C
Precedence Constraint
Evaluation Operation: Expression and Constraint
Value: Success
Expression: @C > 0 ( I originally tried User::C and received an error message)
Execute SQL Server Agent Job
If step one results greater than 1, then execute the SQL agent job (SRS Report) Using this setup I receive an error message stating "
TITLE: Package Validation Error ------------------------------ Package Validation Error ------------------------------ ADDITIONAL INFORMATION: Error at Package: The expression "@C > 0" must evaluate to True or False. Change the expression to evaluate to a Boolean value. Error at Package: There was an error in the precedence constraint between "Execute SQL Task" and "Execute SQL Server Agent Job Task". (Microsoft.DataTransformationServices.VsIntegration)
Any thought or suggestions would be greatly appreciated.
I am building this as an expression, but it is not working. I am trying to return the row count into a variable to use later in an update statement. What am I doing wrong? I am using a single row result set. I have one variable defined in my result set. I am receiving an error stating: Execute SQL Task: There is an invalid number of result bindings returned for the ResultSetType: "ResultSetType_SingleRow". Any help is appreciated!

I have an sproc that gives an xml result set. I want to save this to a file but by using ssis and script task. Now, I do exec usp_myProc in execute sql task and get the result as xml. (I can get it as result set too but niether has worked). Now I pass this variable to my script task User::XRset.
In the script task I create a file and then I want to write xml result of User::XRset to my file. I am at loss.
I cannot find the data type for parameter mapping from Execute SQL Task Editor to make this works.
1. Execute SQL Task 1 - select max(columnA) from tableA. ColumnA is varbinary(8); set result to variable which data type is Object.
2. Execute SQL Task 2 - update tableB set columnB = ? What data type should I use to map the parameter? I tried different data types, none working except GUI but it returned wrong result.
Does SSIS variable support varbinary data type? I know there's a bug issue with bigint data type and there's a work-around. Is it same situation with varbinary?
I set up a connection to mysql using ADO.NET's ODBC Data Provider. And I'm running a simple query to return one table's maximum ID(int32 unsigned). There is no problem to achieve that.
But when I bind the result to a variable and excute task. It gives out error message: "An error occurred while assigning a value to variable "MaxAuditLogID": "Result binding by name "MaxID" is not supported for this connection type. "
I tried to change the type of variable around but with no luck.
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
In the Control flow tab, I have an Execute SQL Task that outputs full Result set into a variable of an object type. Now how can I write the contents of the Full Result Set into a text file using Script Task. I also want to format the following way while I output into a file:
Column Name 1 : Column Value
Column Name 2: Column Value and so on
I tried writing the contents of the Object Variable into a file, but the file had an output of single word: System.__ComObject.
Code for Writing the Full Result Set into a Text File
Dim RSsqloutput as String = Dts.Variables("objVariable").Value.ToString
Dim strVal as String = "File completed on " & Now() & vbCrLf & "------------------------------------------------------" & vbCrLf
I have a stored procedure that is executed via a sql script task that returns a full result set. I map this result set to a variable or object type. Is there a way to use this variable as a data source in a subsequent data flow task?
I'm working on an SSIS package that uses a vb.net script to grab some XML from a webservice (I'd explain why I'm not using a web service task here, but I'd just get angry), and I wish to then assign the XML string to a package variable which then gets sent along to a DataFlow Task that contains an XML Source that points at said variable. when I copy the XML string into the variable value in the script, if do a quickwatch on the variable (as in Dts.Variable("MyXML").value) it looks as though the new value has been copied to the variable, but when I step out of that task and look at the package explorer the variable is its original value.
I think the problem is that the dataflow XML source has a lock on the variable and so the script task isn't affecting it. Does anyone have any experience with this kind of problem, or know a workaround?
I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:
DECLARE @DV INT; SET @DV = (SELECT MAX(DateValue) FROM tblTG); DECLARE @PV INT; SET @PV = @DV - 1;
I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:
DECLARE @DV INT; SET @DV = ?; DECLARE @PV INT; SET @PV = @DV - 1;
I have almost 50 references to these parameters in the query so a substitution would be helpful.
Hi!Can anybody give me a hint how to put sa resut from EXEC into avariable.EXEC is called:EXEC(@TmpQuery) and it returns a single int value (SELECT COUNT(*)....)Thanks!Mario.
I've got two Sql Tasks on my dtsx. The first one loads a value into "Proyecto" user variable and the second one executes a variable named "SegundoProceso" which contains from the beginning:
"select Fecha from LogsCargaExcel where Proyecto = " + @[User::Proyecto] +"" As SqlSourceType propety I have "Variable" and inside ResultSet or Parameter Mapping nodes there is nothing.
[Execute SQL Task] Error: Executing the query ""select Fecha from LogsCargaExcel where Proyecto = " + @[User::Proyecto] +""" failed with the following error: "Cannot use empty object or column names. Use a single space if necessary.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I have an Execute SQL Task (OLE DB Connnection Manager) with a SQL script in it. In this script I use several SQL variables (@my_variable). I would like to assign an IS variable ([User::My_Variable]) to one of my SQL variables on this script. Example:
DECLARE @my_variable int
, <several_others>
SET @my_variable = ?
<do_some_stuff>
Of course, I also set up the parameter mapping.
However, it seems this is not possible. Assigning a variable using a ? only seems to work in simple T-SQL statements.
I have several reasons for wanting to do this:
- the script uses several variables, several times. Not all SQL variables are assigned via IS variables.
- For reading and mainenance purposes, I prefer to pass the variable only once. Otherwise every time the script changes u need to keep track of all questionmarks and their order.
- Passing the variable once also makes it easier to design the script outside IS using Management Studio.
- This script only does preparation for the actual ETL, so I prefer to keep it in one task instead of taking it apart to several consecutive Execute SQL Tasks.
- I prefer to use the OLE DB connection manager because it's a de facto standard here.
Could anyone help me out with the following questions:
- Is the above possible?
- If so, how?
- If not, why not?
- If not, what would be the best way around this problem?
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.
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 it possible to get the result from an EXEC(@sqlcommand) statement into a variable?
As part of a SQL loop, it is necessary for me to run an EXEC() command to process an SQL statement. I have succesfully implemented this, but have been unable to get the results from the EXEC() statement into a variable to allow this data to be inserted into a table. Is this possible?
For Example (I know this doesn't work, but it is effectively what I am trying to achieve):
select @result = EXEC(@sqlcommand)
I could then use the @result variable in an insert statement to update a table with the results from the EXEC command.
My Problem is :im my transaction i use insert code like the following :
" Insert into TAB1 (F1,F2,F3) select a.F1,b.F2,b.F3 from TAB2 a,TAB3 b where a.KY1= b.KY1 and b.ORDN in (Select ORDN from OTAB where USER_ID = 'MIKE')"
In order to optimise my code , instead of using a subquery in my select (I have different insert in my transaction with the same subquery). I would like to DECLARE a varibale which will contain the select of the Subquery. and then use it im my different insert. some thing like this.
" BEGIN TRANSACTION DECLARE @OrdSelect int Set @OrdSelect = (Select ORDN from OTAB where USER_ID = 'MIKE') Insert into TAB1 (F1,F2,F3) select a.F1,b.F2,b.F3 from TAB2 a,TAB3 b where a.KY1= b.KY1 and b.ORDN in @OrdSelect COMMIT Tran "
I know that the @OrdSelect will receive the last value of the select not an array of values. which will make my transaction incorrect. I dont want to use Cursor to resolve this issue Too.

I have also tried: select MAX(field_ + @stri + _ORDER) INTO @max = FROM display_1a WHERE field_ + @stri + IS NOT NULL -- error: Incorrect syntax near '@max'.
and: select @max = ('SELECT MAX(field_' + @stri + '_ORDER) FROM display_1a WHERE field_' + @stri + ' IS NOT NULL') -- error: Conversion failed when converting the varchar value 'SELECT MAX(field_19_ORDER) FROM display_1a WHERE field_19 IS NOT NULL' to data type int.
I wrote a stored procedure that finds a number. I want to store the number it finds into a variable so i can use it within another procedure. I hope i'm being clear. Any help will be appreciated. Here is an example of how i am finding my number Employee is the name of my table and Number is the name of my column.
