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 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.
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 want to look at the size of the current database, so I can create a newone if it gets too big (we are working around the 2gb MSDE limit for ourcustomers).I would like to do something like this:DECLARE @size INTEGERexecute BLOB0000.dbo.sp_spaceusedand make @size = the database_size column value that sp_spaceused returns.Any way to do this?Thanks.
I have a table that has a number of columns and rows and I need to run a stored procedure to extract data based on the column name and row name. Can anyone help me?
Consider the below code: I am trying to find a way so that my select statement (which will actually be used to insert records) can randomly place values in the Source and Type columns that it selects from a list which in this case is records in a table variable. I dont really want to perform the insert inside a loop since the production version will work with millions of records. Anyone have any suggestions of how to change the subqueries that constitute these columns so that they are randomized?
SET NOCOUNT ON
Declare @RandomRecordCount as int, @Counter as int Select @RandomRecordCount = 1000
Declare @Type table (Name nvarchar(200) NOT NULL) Declare @Source table (Name nvarchar(200) NOT NULL) Declare @Users table (Name nvarchar(200) NOT NULL) Declare @NumericBase table (Number int not null)
Set @Counter = 0
while @Counter < @RandomRecordCount begin Insert into @NumericBase(Number)Values(@Counter) set @Counter = @Counter + 1 end
Insert into @Type(Name) Select 'Type: Buick' UNION ALL Select 'Type: Cadillac' UNION ALL Select 'Type: Chevrolet' UNION ALL Select 'Type: GMC'
Insert into @Source(Name) Select 'Source: Japan' UNION ALL Select 'Source: China' UNION ALL Select 'Source: Spain' UNION ALL Select 'Source: India' UNION ALL Select 'Source: USA'
Insert into @Users(Name) Select 'keith' UNION ALL Select 'kevin' UNION ALL Select 'chris' UNION ALL Select 'chad' UNION ALL Select 'brian'
select 1 ProviderId, -- static value '' Identifier, '' ClassificationCode, (select TOP 1 Name from @Source order by newid()) Source, (select TOP 1 Name from @Type order by newid()) Type
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.
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 ?
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
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 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,
buddies,situation: a processing must take place on every row of a table, andoutput results to another table, that can't be done via an insertinto..select query (let's assume that it's not possible for now).There're 2 solutions I have in mind:1) open a cursor and cycle through each row (The table can have up to1M rows)2) create a clustered index (i.e on an identity column) then have aloop like:declare @i int, @rows int,@col1 varchar(20), @col2 varchar(20),... @coln varchar(20),@outval1 varchar(20),... -- output valuesselect @i=1, @rows = max(xid) from tblname -- xid is clustered indexedwhile (@i<=@rows)beginselect @col1 = col1, @col2 = col2,...@coln = colnfrom tblnamewhere xid = i-- do the processing on the variables-- then insert results to another tableset @i = @i+1endI'd like to know your ideas of which one would be more efficient. Anyother solutions are much appreciatedthanks,Tamy
In my previous post I asked how to do the bottom question. I got a response to use a cursor, now I made an attempt to use a cursor but I still get the same response. Any help will be greatly appreciated.

Another question for all you SQL experts, I have a lot of them. I am trying to select from a table wher some conditions need to be met based on an employee ID. What I am doing is when the rank is a 1,2, or 3 I pick up the text description of that rank. Can I make it so that I get the ID only once and all the text descriptions are on the same line. Here is the sql script along with my current output and my desired output.

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.
