Variable In CURSOR Sql Statement (was Please Help Me)
Dec 24, 2004
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 ?
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?
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.
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.

Hi, 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
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????
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.
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 @table table (col1 nvarchar(50), col2 nvarchar(50)) declare curs for select * from sometable open curs fetch next from curs into @table
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?
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.
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
I failed to find record when using variable in cursor in WHERE clause:
ID is uniqueidentifier field in the table DECLARE @EncounterID uniqueidentifier ........ WHERE ID = @EncounterID -> this does not work, though @EncounterID is set properly and can see its value in debugger
WHERE ID = 'E3AE2C5B-06F2-4A3C-A3A4-7D6CC43DE012' -> this works fine and record found
Tried to CAST(@EncounterID as char(40)) but still no luck.
I would greatly appreciate any advise hot to make it working.
I'm just know basic SQL but not enough to write any complex queries.The problem I'm facing right now keeps me thinking to use a Cursor butI've seen a lot of posts on here saying Cursors are bad so I'm hopingthere is a complex query that can give me the data I need.I have about 6 pages in website where I need to display a datagrid ofinformation. There should be 5 columns, Filename, and then 4 CategoryTitles (These category titles are stored in a table calledPageCategory). I have another table, XREF_Doc_Page that stores thePageID, DocID (ID to know what file it is), and PageCategoryID. So Ican query this table with a pageID to see all the results that shouldbe on this page but I don't know how to format it the way I need mydatagrid?In order to have the records from PageCategory be columns, is this acrosstab query or something?My only thoughts right now are to user a cursor to query Pagecategoryand build a temp table somehow with these as the columns?? (Not surehow'd that would work yet).So the datagrid would have the 5 columns like I said and then justlist all files associated with this page and put a checkmark underwhichever category it was assigned to (example below...)Files PageCat1 PageCat2PageCat3 PageCat4abc.pdf Xxyz.pdf Xjkl.pdfx
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,
I have a stored procedure that rertrieves data from an sql database and sends out a mail to each receipient who meets the criteria
I am using SQL mail.
I dynamically generate the where clause for my sql query based on criteria taken from other stored procedures and store it in a varchar variable called @sqlquery
When i have the following code to run my cursor
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.
What should i do. i have tested the variable @sqlquery and it is definately not blank. There is no bracket error or anything.

I know You can write a Sp with cursor and do this, but I would like to know if you can accomplish the same thing by a select or case or something else instead of a cursor.
I would like to get the results of a cursor into update statement but it fills only the last record of the cursor
this is the cursor:
Code: DECLARE @avg varchar(50) DECLARE @cur_avg CURSOR SET @cur_avg = CURSOR FOR select cast(avg(cast(reply as decimal(12,2))) as decimal(12,2)) from tbl_app_monitoring group by test_name, application_id
this is the update statement:
Code: OPEN @cur_avg FETCH @cur_avg INTO @avg WHILE (@@FETCH_STATUS = 0) BEGIN UPDATE tbl_app_monitoring_archive SET average = @avg FETCH @cur_avg INTO @avg END
is it also possible to do this without the cursor ?
I have a cursor that goes through a table with the names of all the database in my server. So for each fetch, the cursor gets the name of a database and assign it to a variable, @databaseName, and try to do some queries from that database by using the command "USE @databaseName". But "USE" doesn't take the variable @databaseName; it is expecting a database name (i.e. USE master).
Here is my code:
Declare @databaseName varchar(50) Declare c_getDatabaseName CURSOR for SELECT name from tblDatabases OPEN c_getDatabaseName FETCH NEXT from c_getDatabaseName into @databaseName While @@FETCH_STATUS = 0
Help please,Have a situation when converting from Oracle SP's to SQL SP's.

I know I can assign the wholeselect statement to a string and use exec to exec the string to get arecordset but how can I point a cursor to receive its output?i.e.set @strSQl = select top ' + @numQuantity + ' StockRowId, CategoryId.......exec @strSQLbut how do I dodeclare cur_rsStockset cur_rsStock = ( exec @strSQL)Flapper

I am hoping someone can help me with using the cursor and fetch functions. I have not used these features in the past and I am now stuck when trying to use IF statements with the fetch function.
I have a temp table populated with the below headers and their associated data.
The headers are as follows: ItemRcvdKey, TranID, TranDate, QtyReceived, UnitCost, ItemKey, WhseKey, ItemID, ShortDesc, WhseID, QtyOnHand, StdCost.
The information contained in this temp table lists every single receipt of goods against all of our inventoried items. The QtyOnHand listed on each record is the total QtyOnHand for that item in that warehouse. What I need the fetch to do is grab the receipt of goods records, starting with the most recent TranDate, and pull them into the new temp table until the QtyOnHand is reached. The QtyonHand it should be comparing too is the one listed on the first fetched record. Once the Sum of the QtyRcvd is equal to or is greater than the QtyOnHand for that item I need the fetch to move on to the next item number and perform the same function.
One thing I need to be clear on is that if there are 3 Receipt Records(TranID) for Item A in Warehouse A, the total QtyOnHand will be listed 3 times. I need to make sure that the Fetch is comparing all the records for Item A in Warehouse A to one instance of the QtyOnHand.
The other aspect is that there will be receipt of goods for the same item in multiple warehouses. So I also need the Fetch to be sure that when it is grabbing records and putting them in the temp table, it makes sure it is matching the ItemID and the WhseID with the record it started with.
The current script I have written is below. If you can offer any help I would greatly appreciate it.
