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.
The following query is failing when trying to apply the MAX(field_x_order) to the variable @max Note the x is represented by the string variable @stri
declare @i int declare @stri varchar(10) declare @max int set @i = 18 set @max = 0 while @i < 49 begin set @i = @i + 1 set @stri = cast(@i as varchar(10)) select @max = MAX(field_ + @stri + _ORDER) FROM table_name WHERE field_ + @stri + IS NOT NULL -- error: Incorrect syntax near the keyword 'IS'. exec ('UPDATE display_1a SET field_' + @stri + '_order = field_' + @stri + '_order ' + @max + 'WHERE field_' + @stri + ' IS NULL') end
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.
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 have a dynamic query which returns me a result and I want to capture that value to make further use of it in the same code. Is that possible?? exec ('select col_nm from table_name'). i want the result of this query to be captured. DP
Is there a way to assign a dynamic query result to a local variable?
declre @sqlString nvarchar(4000), @minEventDate datetime, @databaseName varchar(25) selct @databaseName = 'customer_12345' (actually, a cursor loop will assign the database name dynamically, here just to simplify the situation)
Though the select min(eventDate) from customer_12345.dbo.tblABC returns a date, ex. '02/01/2004 12:35 pm', however, the printed @minEventDate is always with Null value. It mean, the value was never correctly assigned to the local variable.
As an alternate way, I am using temp table to insert it with the query result and then assign to the local variable. Since I have many local variables to try to get the min, max, count for around 10 fields, perfer a way to direct assign to the local variable instead of 10 temp tables.
I am trying to store the column value to a variable from a distributed query.
The query is formed on the fly.
i need to accomplish something like this
declare @id int declare @columnval varchar(50) declare @query varchar(1024) @Query = "select @columnval = Name from server.database.dbo.table where id ="+convert(varchar,@ID) exec (@query) print @Columnname
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.
HI, I ran a select * from customers where state ='va', this is the result...
(29 row(s) affected) The following file has been saved successfully: C:outputcustomers.rpt 10826 bytes
I choose Query select to a file then when I tried to open the customer.rpt from the c drive I got this error message. I am not sure why this happend invalid TLV record
As the topic suggests I need the end results to show a list of shows and their dates ordered by date DESC. Tables I have are structured as follows:
SHOWS showID showTitle
SHOWACCESS showID remoteID
VIDEOS videoDate showID
SQL is as follows:
SELECT shows.showID AS showID, shows.showTitle AS showTitle, (SELECT MAX(videos.videoFilmDate) AS vidDate FROM videos WHERE videos.showID = shows.showID) FROM shows, showAccess WHERE shows.showID = showAccess.showID AND showAccess.remoteID=21 ORDER BY vidDate DESC;
I had it ordering by showTitle and it worked fine, but I need it to order by vidDate. Can anyone shed some light on where I am going wrong?
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 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?
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?
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.
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 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.
Hellois there a variable that is available to me that contains the numberof rows contained in a dataset return from a database call? have a class that runs a stored proc and returns a dataset/resultsetlooking to simply assign an integer this value if it is possible i'm using (learning) vb.net and sql server thanks in advance
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.
