I'm not sure about this one so if someone could help I'd appreciate this.
As shown below I've declared a variable name1 to be used in a while statement substituting for an object name in a select statement (2000 SP3a)
and throwing the shown error. Are variables allowed to be used to substitute for object names or is there another problem? Thanks.
if i have the cursor
cursor:
cursor for
select name
from sysobjects
where type='P' AND category='0'
and wants a variable before sysobjects which equals a table name, so itll be:
cursor for
select name
from @variable..sysobjects
where type='P' AND category='0'
how do i include a variable within a cursor statement
Hello All,Is there a T-SQL equivalent of the PL/SQL cursor rowtype datatype ?Thanks in advance
View 2 Replies View RelatedI am currently using a cursor to scroll through sysobjects to extract table names and then extracting relevant column names from syscolumns.
I then need to run the following script:
declare Detail_Cursor cursor for
select @colname, max(len(@colname)) from @table
The message I receive is "must declare variable @table".
Immediately prior to this script I printed out the result of @table which works fine so the variable obviously is declared and populated.
Can anyone let me know what I'm doing wrong or how I can get the same result.
Thanks
Hi All,
What i am trying to do is concatenate variable "@Where" with CURSOR sql statement,inside a procedure . But, it doesn't seem to get the value for
the @Where. (I tried with DEBUGGING option of Query Analyzer also).
=============================================
SET @Where = ''
if IsNull(@Input1,NULL) <> NULL
Set @Where = @Where + " AND studentid='" + @input1 +"'"
if isnull(@Input2,NULL) <> NULL
Set @Where = @Where + " AND teacherid =' " + @Input2 +"'"
DECLARE curs1 CURSOR SCROLL
FOR SELECT
firstname
FROM
school
WHERE
school ='ABC' + @where
=============================================
Please check my SQL Above and Could somebody tell me how can I attach the VARIABLE with CURSOR sql statement ?
Thanks !
Hi,
I have a problem on setting the value for the variable in a declared cursor. Below is my example, I have declared the cursor c1 once at the top in a stored procedure and open it many times in a loop by setting the variable @str_var to different values. It seems the variable cannot be set after the cursor declared. Please advise how can I solve this issue.
------------------------------------------------------------------------
DECLARE @str_var VARCHAR(10)
DECLARE @field_val VARCHAR(10)
DECLARE c1 CURSOR LOCAL FOR
SELECT field1 FROM tableA WHERE field1 = @str_var
WHILE (Sometime TRUE)
BEGIN
....
SET @str_var = 'set to some values, eg. ABC123, XYZ123'
OPEN c1
FETCH c1 INTO @field_val
WHILE (@@fetch_status != -1)
BEGIN
PRINT @field_val
...
FETCH c1 INTO @field_val
END
CLOSE c1
END
DEALLOCATE c1

Thanks a lots,

View 1 Replies View RelatedHi,
I need a small help. In my stored procedure, i create a table variable and fill it with records based on my query. The ID field within the table is not continous and can have any value in increasing order .e.g. The ID sequence may be like 20, 33, 34, 59, 78, 79... I want to iterate through each record within the table but without using a Cursor. I want to use a loop for this purpose. There are many articles pointing out how to iterate through records in a table variable but that requires the IDs to be continous which is not possible in my case. Can anyone help me solve this problem...
Any help is appreciated...
When I execute next query on sqlserver 6.5 nested in stored procedure I can see that 'open testCursor' selected rows using new value of @var. When I execute query on sqlserver 7.0 I can see that 'open testCursor' selected rows using value of @var before 'declare ... cursor'. Is there any way to force sqlserver 7.0 to proccess cursor like it did it before.
select @var = oldValue
declare testCursor cursor
for select someColumns
from someTable
where someColumn = @var
select @var = newValue
open testCursor
fetch next from testCursor into @someColumns
Thank's in advance.
Mirko.
I'm trying to build a select statement for a CURSOR where part of the SQL statement is built using a variable.
The following fails to parse:
Declare Cursor1 Cursor
For
'select table_name from ' + @database + '.Information_Schema.Tables Where Table_Type = ''Base Table'' order by Table_Name'
Open cursor1
That doesn't work, I've also tried using an Execute() statement, no luck there either. Any ideas or suggestions are greatly appreciated.
I can't seem to get a cursor to work when I'm passing in a variable for a column name of the select statement. For example:
declare @col varchar(50)
set @col = 'Temperature'
declare notifycurs cursor scroll for
select @col from Table
Obviously this won't work correctly (since the result will simply be 'Temperature' instead of the actual float value for temperature). I tried to use quotes for the entire statement with an EXEC
(ie. exec('select '+@col+' from Table' )
but that gave me an error.
Is there a way to pass in a variable for a column name for a curor select statement????
I'm trying something like:
UPDATE tbl SET @varFieldName = @varValue
The procedure runs, and when I PRINT @varFieldName, it looks fine, but the table isn't getting updated, and no errors, wierd.
I have the CURSOR open for update, but I didn't list the field names, that shouldn't be a problem, as all fields should be updateable then.
To get the field name, I :
SET @varFieldName = 'SomeChars' + LTRIM(STR(asmallint)) + 'SomeMoreChars'
Thanks,

A select statement returns one column with more than one rows.Is there a way to store it in sql Variable without using a Cursor.
Thank you in advance
Hello,
I have searched the net for an answer but could not find one. When I declare a table variable
and then try to insert fetched row into the table variable like:
Code Snippet

declare curs for
select * from sometable
open curs
fetch next from curs into @table
it does not work. any help would be great.

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?
The below cursor is giving an error
DECLARE @Table_Name NVARCHAR(MAX) ,
@Field_Name NVARCHAR(MAX) ,
@Document_Type NVARCHAR(MAX)
DECLARE @SOPCursor AS CURSOR;
SET
@SOPCursor = CURSOR FOR
[Code] ....
The @Table_Name variable is declared, If I replace the delete statement (DELETE FROM @Table_Name ) with (PRINT @table_name) it works and print the table names.
Why does the delete statement give an error ?
After trying every way I could come up with I can't get a filter clauseto work with a passed variable ...I have a cursor that pulls a filter string from a table (works OK),then I want to use that filter in a second cursor, but can't get thesyntax ...@bakfilter is equal to "MISV2_db_%.BAK" before I try to open and fetchfrom the second cursor. Here is the cursor declaration:DECLARE curFiles CURSOR FORSELECT FileName, FileDateFROM DataFileWHERE (((Active)=1) AND ((FileName) LIKE '@bak_filter'))ORDER BY FileDate DESCWhat do I need to do to get it to use the string contained in@bak_filter?Thanks in advance, Jim

Hi
I am ramesh here from go-events.com
I am using sql mail to send out emails to my mailing list
I have difficulty combining a select statement with a where clause stored in a variable inside a cursor
The users select the mail content and frequency of delivery and i deliver the mail
I use lots of queries and a stored procedure to retrieve thier preferences. In the end i use a cursor to send out mails to each of them.
Because my query is dynamic, the where clause of my select statement is stored in a variable. I have the following code
that does not work
For example
DECLARE overdue3 CURSOR
LOCAL FORWARD_ONLY
FOR SELECT DISTINCT Events.E_Name, Events.E_SDate, Events.E_City, Events.E_ID FROM Events, IndustryEvents + @sqlquery2
OPEN overdue3
I get an error message at the '+' sign
which says, cannot use empty object or column names, use a single
space if necessary
How do I combine the select statement with the where clause?
Help me...I need help urgently
Hi all.
I am stuck in a bit of a conundrum for quite a while now, and I hope someone here will help me figure this one out.
So, first things first: let me explain what I need to do. I am
designing a web application that will allow users to consult info
available in a SQL2000 database. The user will enter the search
criterea, and hopefully the web page will show matching results.
The problem is the results shown aren't available per se in the DB, I
need to process the data a bit. I decided to do so on the SQL Server
side, though the use of cursors. So, when a user defines his search
criteria, I run a stored procedure that begins by building a dynamic
sql query and creating a cursor for it. I used a global cursor in order
to do so. It looked something like this:
SET @sqlQuery = ... (build the dinamic sql query)
SET @cursorQuery = 'DECLARE myCursor CURSOR GLOBAL FAST_FORWARD FOR ' + @sqlQuery
EXEC @cursorQuery
OPEN myCursor
FETCH NEXT FROM myCursor INTO ...
CLOSE myCursor
DEALLOCATE myCursor
This works fine, if there's only one instance of the
stored procedure running at a time. Should another user connect to the
site and run a search while someone's at it, it'll fail due to the
atempt to create a cursor with the same name.
My first thought was to make the cursor name unique, which led me to:
...
SET @cursorName = 'myCursor' + @uniqueUserID
SET @cursorQuery = 'DECLARE '+ @cursorName + 'CURSOR FAST_FORWARD FOR ' + @sqlQuery
EXEC @cursorQuery
...
The problem with this is that I can't do a FETCH NEXT FROM @cursorName since
@cursorName is a char variable holding the cursor name, and not a
cursor variable. So to enforce this unique name method the only option
I have is to keep creating dynamic sql queries and exucting them. And
this makes the sp a bitch to develop and maintain, and I'm guessing it
doesn't make it very performant.
So I moved on to my second idea: local cursor variables. The problem with
this is that if I create a local cursor variable by executing a dynamic
query, I can't extract it from the EXEC (or sp_executesql) context, as
it offers no output variable.
I guess my concrete questions are:
Is it possible to execute a dynamic sql query and extract a (cursor) variable from it?Is it possible to populate a local cursor variable with a global cursor, by providing the global cursor's name?Can I create a local cursor variable for a dynamic sql query? How?
Anybody sees another way arround this?Thanks in advance,
Carlos
In MSDN file I read about static cursor
STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that
Static Cursor
declare ll cursor global static
           for select name, salary from ag
 open ll
            fetch from ll
Â
             while @@FETCH_STATUS=0
              fetch from ll
               update ag set salary=200 where 1=1
Â
  close ll
deallocate ll
In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says modifications is not allowed in the static cursor.But I am able to update the data using static cursor.
Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin

View 1 Replies View RelatedI'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.

I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.
Here are the task steps.
[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.
[Execute SQL Task] - Log an entry to a table indicating that the import has started.
[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.
[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.
If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.
If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post.
Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.
CREATE PROCEDURE [dbo].[p_CheckImportFileCreateDate]
/*
The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.
If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.
Otherwise it returns a FALSE value in the IsNewFile column.
Example:
exec p_CheckImportFileCreateDate 'GL Account Import', '2/27/2008 9:24 AM', 0
*/
@ProcessName varchar(50)
, @FileCreateDate datetime
, @IsNewFile bit OUTPUT
AS
SET NOCOUNT ON
--DECLARE @IsNewFile bit
DECLARE @CreateDateInTable datetime
SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName
IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)
BEGIN
-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.
IF (@FileCreateDate > @CreateDateInTable)
BEGIN
-- This is a newer file date. Update the table and set @IsNewFile to TRUE.
UPDATE tbl_ImportFileCreateDate
SET FileCreateDate = @FileCreateDate
WHERE ProcessName = @ProcessName
SET @IsNewFile = 1
END
ELSE
BEGIN
-- The file date is the same or older.
SET @IsNewFile = 0
END
END
ELSE
BEGIN
-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.
INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)
VALUES (@ProcessName, @FileCreateDate)
SET @IsNewFile = 1
END
SELECT @IsNewFile
The relevant Global Variables in the package are defined as follows:
Name : Scope : Date Type : Value
FileCreateDate : (Package Name) : DateType : 1/1/2000
IsNewFile : (Package Name) : Boolean : False
Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.
General
Name = Compare Last File Create Date
Description = Compares the create date of the current file with a value in tbl_ImportFileCreateDate.
TimeOut = 0
CodePage = 1252
ResultSet = None
ConnectionType = OLE DB
Connection = MyServerDataBase
SQLSourceType = Direct input
IsQueryStoredProcedure = False
BypassPrepare = True
I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate.
SQLStatement = exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
SQLStatement = exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
Parameter Mapping
Variable Name = User::FileCreateDate, Direction = Input, DataType = DATE, Parameter Name = 0, Parameter Size = -1
Variable Name = User::IsNewFile, Direction = Output, DataType = BYTE, Parameter Name = 1, Parameter Size = -1
Result Set is empty.
Expressions is empty.
When I run this in debug mode with this SQL statement ...
exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the following error message appears.
SSIS package "MyPackage.dtsx" starting.

When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.
When I run this in debug mode with this SQL statement ...
exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the tbl_ImportFileCreateDate table gets updated. So I know that data piece is working, but then it fails with the following message.

The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?
The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.
Thanks for your help.
I am in the middle of taking course 2073B €“ Programming a Microsoft SQL Server 2000 Database. I noticed that in Module9: Implementing User-Defined Functions exercise 2, page 25; step 2 is not returning the correct answer.
Select employeeid,name,title,mgremployeeid from dbo.fn_findreports(2)
It returns manager id for both 2 and 5 and I think it should just return the results only for manager id 2. The query results for step 1 is correct but not for step 2.
Somewhere in the code I think it should compare the inemployeeid with the previous inemployeeid, and then add a counter. If the two inemployeeid are not the same then reset the counter. Then maybe add an if statement or a case statement. Can you help with the logic? Thanks!
Here is the code of the function in the book:
/*
** fn_FindReports.sql
**
** This multi-statement table-valued user-defined
** function takes an EmplyeeID number as its parameter
** and provides information about all employees who
** report to that person.
*/
USE ClassNorthwind
GO
/*
** As a multi-statement table-valued user-defined
** function it starts with the function name,
** input parameter definition and defines the output
** table.
*/
CREATE FUNCTION fn_FindReports (@InEmployeeID char(5))
RETURNS @reports TABLE
(EmployeeID char(5) PRIMARY KEY,
Name nvarchar(40) NOT NULL,
Title nvarchar(30),
MgrEmployeeID int,
processed tinyint default 0)
-- Returns a result set that lists all the employees who
-- report to a given employee directly or indirectly
AS
BEGIN
DECLARE @RowsAdded int
-- Initialize @reports with direct reports of the given employee
INSERT @reports
SELECT EmployeeID, Name = FirstName + ' ' + LastName, Title, ReportsTo, 0
FROM EMPLOYEES
WHERE ReportsTo = @InEmployeeID
SET @RowsAdded = @@rowcount
-- While new employees were added in the previous iteration
WHILE @RowsAdded > 0
BEGIN
-- Mark all employee records whose direct reports are going to be
-- found in this iteration
UPDATE @reports
SET processed = 1
WHERE processed = 0
-- Insert employees who report to employees marked 1
INSERT @reports
SELECT e.EmployeeID, Name = FirstName + ' ' + LastName , e.Title, e.ReportsTo, 0
FROM employees e, @reports r
WHERE e.ReportsTo = r.EmployeeID
AND r.processed = 1
SET @RowsAdded = @@rowcount
-- Mark all employee records whose direct reports have been
-- found in this iteration
UPDATE @reports
SET processed = 2
WHERE processed = 1
END
RETURN -- Provides the value of @reports as the result
END
GO
