I am reviewing some code we have inherited (riddled with multiple nested cursors) and in the process of re-writing some of the code. I came across this and it has me puzzled.
As I understand it, if you declare a variable and then try to re-declare a variable of the same name an error is generated. If I do this inside a While loop this does not seem to be the case. What ever is assigned is kept and just added to (in the case of a table variable)
I understand things are in scope for the batch currently running but I would expect an error to return (example 1 and 2)

I am using a cursor (i know - but this is actually something that is a procedural loop).
So effectively i have a table of names of stored procedures. I now have a store proc that loops around these procs and runs each one in order.
Now i am thinking i would like to be able to set the table it loops around in a variable at the start - is it possible to do this? So effectively use a tablename in a variable to use in the sql to define a cursor?
i have used @ symbol for declaring local variables in stored procedure.... The symbol @@ is there....where to use and what is the purpose of using that symbol...
Can someone say how to declare a record like variable in MSSQL-2000 Like: mr_rec record of variables a int, b char(20), c datetime? I could not find any examples on BOL. I want to use this in a stored procedure create script.
here is the code segment below; ... DECLARE find_dates CURSOR FOR SELECT @SQL = 'select DISTINC(Dates) from ['+@name+'].dbo.['+@t_name+'] order by [Dates] ASC' EXEC (@SQL)
but it gives error, variable assignment is not allowed in a cursor declaration. I need to use dynamic SQL , the only way to access all the dbs and their tables inside. Please help.
Is there a way to write such a query where we can declare the variable dynamically ? Currently I am using the query as shown below :
declare @pYear_Internal as NVarchar(100) set @pYear_Internal = [D FISCALPERIOD].[FP CODE].[FP CODE] WITH MEMBER MEASURES.[REVENUE] AS [Measures].[TOTAL REVENUE] SET LAST5YEARS AS STRTOMEMBER(@pYear_Internal).Lag(4) : STRTOMEMBER(@pYear_Internal)
[code]....
While executing the above query, getting the error - Query (1, 9) Parser: The syntax for '@pYear_Internal' is incorrect. Â It looks like it doesn't recognize DECLARE keyword as it does with SQL queries. Â I just want a query that runs directly against the server.Â
I've been curious why some variables don't need to be declared with a value type in a stored procedure. Please see the example below in the bolded area. The stored procedure works fine - nothing is wrong with it, but I just wanted an explanation on why and when is a value type not needed for a variable.
CREATE PROCEDURE [DBO].[EmailRpt] ( @TagDest char(2) = NULL, @DateWanted smalldatetime = NULL, @CustName varchar(64) = NULL, @AcctID AcctId = NULL, @ContactPhn phone = NULL, @CustAddr address = NULL, @City city, @CrossSt varchar(50) , @Access varchar(50) = NULL, @Activity tinyint, ) AS DECLARE @String as varchar(2000), @Header as varchar(200), @MailBox as varchar(50), @ActivityName as Name, @Return as int, @UserName as Name
is there any way or a tool to identify if in procedure the Parameter length was declarated less than table Column length ..
I have a table
CREATE TABLE TEST001 (KeyName Varchar(100) ) a procedure CREATE PROCEDURE SpFindNames ( @KeyName VARCHAR(40) ) AS BEGIN SELECT KeyName FROM TEST001 WHERE KeyName = @KeyName END KeyName = @KeyName
Here table Column with 100 char length "KeyName" was compared with SP parameter "@KeyName" with length 40 char ..
IS there any way to find out all such usage on the ALL Procedures in the Database ?
I encountered a werid bug that I can't figure it out in my stored procedure.Here's some sample code the can represent the scenario
Create Proc sp_test @DeptID Int as Begin Declare @i int=0 Declare @Count int=(Select count(*) from Total) while(@i<@Count)
[code]....
In the above code Total is a table that has employee name and its department ID and row_number info.The above code should list all employee info that belongs to one DEpt.but after I placed a try catch block the select statement returns no records.If I removed the try catch block it behaves correct.For example If three records reside in the Total table for a certain DeptID.
I expect the outPut will be Name age salary Mike 35 $60006 Tom 50 $75000 Frank 55 $120000
I am running the following query, which deletes around 800 million rows from the table.
I would like to introduce transactions with in this code and also, if success entire deletion process should be committed and number of rows deleted, table name and success should be inserted to the log table.
If there is a failure, transaction should be rolled back and table name and error message should be inserted to the same log file
Select 1 While @@ROWCOUNT > 0 Begin DELETE Top(100000) FROM [dbo].[Table1] FROM [dbo].[Table2] INNER JOIN [dbo].[Table3] ON [Table2].[PracticeID] = [Table3].[PracticeID] INNER JOIN [dbo].[Table1] ON [Table3].[InputDevicePracticeID] = [Table1].[InputDevicePracticeID] WHERE [Table2].PracticeID =55; End
Need getting the below Cursor query convert to a Recursive CTE or with a while loop as I do not want to use a cursor.

I'm trying to build a simple cursor to understand how they work. From the temp table, I would like to print out the values of the table, when I run my cursor it just keeps running the output of the first row infinitely. I just want it to print out the 7 rows in the table ...
IF OBJECT_ID('TempDB..#tTable','U') IS NOT NULL DROP TABLE #tTable CREATE TABLE #tTable
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?

Simply trying to move a group of files from one folder to another folder and renaming the files with the monthyear in the middle of the filename..
I'm using a FOR Loop container and works find. The added complexity is I'm trying to rename the files the same tine and putting the Month Year into the file name.
I guess the struggle is how to get the file name out so I can manipulate it.
I tried creating variable(V_SOURCE) which stores the file path and create another variable(V_FILENAME) to hold the filename. I believe on the expression page of the FOR LOOP editor if I select the the file name and extension radio button, it should put the file name in the V_FILENAME variable.
In my file task trying to join the two variables together in another variable, keep saying my path is wrong with the file task kicks off.
I'm have created a data flow that uses an OLEDB source with a SQL Query. In the WHERE statement of this query is a condition for the storecode. I want to figure out how to create a loop that will cycle through a list of storecodes using a variable which is passed to the dataflow in turn to the OLEDB source's query and runs through the process for each store.
The reason i'm using a loop is because there are about 15 million records that are merge joined with 15 million others which is causing a huge performance problem. I'm hoping that by looping the process with one store at a time it should be faster. Any ideas would be greatly appreciated.
CREATE TABLE dbo.MyEmployees ( EmployeeID smallint NOT NULL, FirstName nvarchar(30)  NOT NULL, LastName  nvarchar(40) NOT NULL, Title nvarchar(50) NOT NULL, DeptID smallint NOT NULL, ManagerID int NULL,  CONSTRAINT PK_EmployeeID PRIMARY KEY CLUSTERED (EmployeeID ASC) );
-- Populate the table with values.
INSERT INTO dbo.MyEmployees VALUES  (1, N'Ken', N'Sánchez', N'Chief Executive Officer',16,NULL) ,(273, N'Brian', N'Welcker', N'Vice President of Sales',3,1) ,(274, N'Stephen', N'Jiang', N'North American Sales Manager',3,273) ,(275, N'Michael', N'Blythe', N'Sales Representative',3,274)
In 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 need some help regarding a conversion in a Script Task.
I am reading my variable values from a database with a sql task, the table has two columns, variable and variableValue. Looping through the recordset and setting the different variables works well, with two links: http://blogs.conchango.com/jamiethomson/archive/2005/02/09/SSIS_3A00_-Writing-to-a-variable-from-a-script-task.aspx http://sqlblog.com/blogs/andy_leonard/archive/2007/10/14/ssis-design-pattern-read-a-dataset-from-variable-in-a-script-task.aspx
setting the variable value only works well if the package variable is defined as string, because the db field is a varchar, trying to assign an integer for example brings up an error.
Therefor I tried something like CType: Dts.Variables("MyVar").Value = CType(MyRecordsetField,String), where the target datatype should be depending on the variable datatype instead of being assigned as a constant.
I have a quick but imp SSIS question. I have a For Each Loop Container, and inside that I wish to add a Execute SQL Task item, so I can call a sp to do some inserts/updates. The ForEachLoop container is looping thru a ADO Object source variable(which is the user variable defined by me, as a FullResultSet). In my Execute SQL Task, I would like to utilize one of the columns from the result set as an input parameter to my Stored procedure. Can someone please advise on how to do this? Please let me know if you have any more questions. I am waiting for a response... Thanks in advance.
I have a problem using SSIS since I was a beginner, the problem is I have to do some data transform from flat files into database. These flat files come from many branches of my office with the file structure like this D:SSISranch_nmfile_nm.txt, in folder SSIS there are many branch_nm folder and each branch_nm folder contains many flat files.
My idea was grab the branch_nm folder into array variable using Script Task and then loop this array variable using ForEach Loop Container to get the file and using it for Flat File connection, but I don't know the way to do it.
May this idea work out for sure ?? How to use array variable, that we previously defined inside Script Task, in ForEach Loop Container ?
In my custom task, I would like to loop over the variables in the variable dispenser, and only modify those that are of a certain type. Is this possible?
I have a Foreeach loop container that is looking for all the files in a specified directory. For each file in the directory I need to open the file, extract the contents, and pass the contents as a variable for a stored procedure call.
I was able to loop thru the files in the directory and see each file and store the name to a variable.
I was able to use an XML task to open one file via a file connection that connects to a specified file and store the contents in a variable and then execute the SQL task using the variable.
What I am unable to figure out is how to put the two processes together and get the XML task to open the file by using the variable that contains the filename. If anyone could help I would really appreciate it.
I have to import a number of excel spreadsheets. I'm using the classic Foreach Loop inside another Foreach loop approach. The outside loop (Foreach File Enumerator) cycles through the Excel files, while the inside loop (Foreach ADO.NET Schema Rowset Enumerator - ExcelSchema - Tables) to cycle through the individual Excel sheets in each file.
Nothing special there; however, for some reason these excel files have some "phantom" tabs that should not be imported. I call them phanton because they show up as an importable tab in a SSSIS import wizard but actually are not listed in the excel file structure (no, they are not hidden tabs, I checked).
My idea is to use a constraint to NOT import those phanton tabs. The name convention should allow me to do that because the normal tabs have the name 'AAAAAAyyyymmdd$' and the phantom tabs show up as 'AAAAAAyyyymmdd$'_xlnm#_FilterDatabase (the line below was captured from the Local Variable window and show one of the phantom tabs name).
I tried using Len (@[User::WorksheetName]) == 17, which corresponds to the length of the normal tabs name ('AAAAAAyyyymmdd$'). However, it does not work. For some reason the portion of the phantom tab name after the ending single quote (_xlnm#_FilterDatabase)Â appears to be ignored.
I tested with a number of different expressions, including reversing the variable, to no avail. It seems that internally just the standard name between quotes is what the constraint sees.
I have a table with Year , Account and Amount as fields. I want to
SELECT Year, Account, sum(Amount) AS Amt
FROM GLTable
WHERE Year <= varYear
varYear being a variable which is each year from a query
SELECT Distinct Year FROM GLTable
My thought was that I would need to pass a variable into a select statement which then would be used as the source in my Data Flow Task.
What I have done is to defined two variables as follows
Name: varYear (this will hold the year)
Scope: Package
Data type: String
Name:vSQL (This will hold a SQL statement using the varYear)
Scope: Package
Data type: String
Value: "SELECT Year, Account, sum(Amount) AS Amount FROM GLTable WHERE Year <=" + @[User::varYear]
I've created a SQL Task as follows
Result set: Full Result Set
Connection Type: OLE DB
SQL Statement: SELECT DISTINCT Year FROM GLTable
Result Name: 0
Variable Name: User::varYear
Next I created a For Each Loop container with the following parameters
Enumerator: Foreach ADO Enumerator
ADO Object source Variable: User::varYear
Enumeration Mode: Rows in First Table
I then created a Data Flow Task in the Foreach Loop Container and as the source used OLE DB Source as follows
Data Access Mode: SQL Command from Variable
Variable Name: User::varYear
However this returns a couple of errors "Statement(s) could not be prepared."
and "Incorrect syntax near '='.".
I'm not sure what is wrong or if this is the right way to accomplish what I am trying to do. I got this from another thread "Passing Variables" started 15 Nov 2005.
I am trying to loop through 4 files in a folder and read the names of those files through the For each loop container task. I have 4 readme files (readme1.txt thru readme4.txt) in a folder called C:SSIS.
I have added a for each Loop container and a script task to my package. In the Variable Mapping page I have named the Variable and configured the index to be 0. The problem is when I execute the package the file name that is read is always readme1.txt. I want all the file names to be read under the folder ( in other words configure the index to be 0 thru 4). How do I configure the index so that it can read all the files?.
The following is the code I have in my script task:
I have a job that runs in sql 2008r2 that declares a value to a variable. This variable is passed to a function. I need to include more values in and am unsure how to do this. @InCo could be 4,5,6,or 7.
It works if I print @s query and run it this way, so the query is correct):
DECLARE @MinBoundary DateTime SELECT @MinBoundary = Convert(DateTime, MIN(PRV.value)) FROM sys.partition_functions AS PF JOIN sys.partition_parameters AS PP ON PF.function_id = PP.function_id
