How To Include Variable In CURSOR SQL Filter Clause?
After trying every way I could come up with I can't get a filter clause
to 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 the
syntax ...
@bakfilter is equal to "MISV2_db_%.BAK" before I try to open and fetch
from the second cursor. Here is the cursor declaration:
DECLARE curFiles CURSOR FOR
SELECT FileName, FileDate
FROM DataFile
WHERE (((Active)=1) AND ((FileName) LIKE '@bak_filter'))
ORDER BY FileDate DESC
What do I need to do to get it to use the string contained in
@bak_filter?
Thanks in advance, Jim

Cursor Declared With Variable In Where Clause
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.

Combing In A Cursor, A Select Statement With The WHERE Clause Stored In A Variable
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

The Cursor Does Not Include The Table ... Error?
We use a lot of virtual machines. I have a base VM with SQL 2005 installed. I rename this VM (i have multiple copies running) and run an old application (VB code, iterates through recordsets, etc.). I get: Microsoft][ODBC SQL Server Driver][SQL Server]Could not find server '2K3VM-DG' in sysservers. Execute sp_addlinkedserver to add the server to sysservers. This makes sense, and I can fix it with sp_dropserver / sp_addserver [local]. Good. The next error is puzzling though: [Microsoft][ODBC SQL Server Driver][SQL Server]The cursor does not include the table being modified or the table is not updatable through the cursor. Any suggestions on how to fix this?

Where Clause Filter
I have an sql script that has 2 main blocks of Where filter which I'd call as Filter1 and Filter2 as follows: Select DisplayColumns... From InterestingTables Where (Filter1) --W1 AND --W2 NOT --W3 (Filter2) --W4 Note that Filter1 and Filter2 are composite filters (inner filters nested; it shouldn't matter as long as I have the outer parenthesis as above, right?). Now, say SetF1ExF2 is the result set of the sql script above. Additionally, let's say I obtain the result set SetF1 by having W2 to W4 commented out and SetF1AndF2 comes from commenting out W3. Shouldn't the following hold: SetF1AndF2 = SetF1 - SetF1ExF2 I am having a discrepancy between the values with SetF1AndF2 < SetF1 - SetF1ExF2. TIA.

Filter Criteria - Temp Table Join Or Where Clause?
I have a set of udf's dealing that return a one column table of valuesparsed from a comma delimeted string.For example:CREATE FUNCTION [dbo].[udf_filter_patient](@patient_list varchar(2000))RETURNS @patient TABLE(patient_id int)ASBEGINinsert into @patientselect patient_id from patient-- parse @patient_list stuff excludedRETURNENDI have come up with the following two schemes to use these udfs. Theseexamples are obviously simplified, and I have a handful of stored proceduresthat will use between 10 or more of these filters. If the two areequivalent, I prefer Method 2 because it makes for much neater SQL whenusing many filter criteria.So my question is, will one noticebly outperform the other? Or is there abetter way in which to filter on a list of criteria?Method 1 :CREATE PROC sp__filter_open_bills@patient_list varchar(2000)ASCREATE TABLE #patient(patient_id int)INSERT INTO #patientSELECTpatient_idFROMdbo.udf_filter_patient( @patient_list )SELECT*FROMopen_billsINNER JOIN #patient on #patient.patient_id = open_bills.patient_idGOMethod 2 :CREATE PROC sp__filter_open_bills@patient_list varchar(2000)ASSELECT*FROMopen_billsWHEREopen_bills.patient_id IN ( SELECT patient_id FROMdbo.udf_filter_patient( @patient_list ) )GOThanks for the help!Chris G

Should We See Replication Filter Where Clause Text In Profiler TextData On SQL Server 2005?
We have Merge Replication publications for SQL Server 2005 Compact Edition subscribers. Some articles have filter statements that send rows to multiple subscribers, based on the value of Host_Name() supplied at run-time. Our publications work for most subscribers, but we have at least one subscriber who downloads too many rows from one of the filtered tables. When we run the Select SQL from the article's Filter statement it returns the intended 4 rows for this subscriber. We cut and pasted the filter statement into query analyzer, substituted the subscriber's value for Host_Name(), executed the statement, and got the proper 4 rows for this subscriber in the results. But when this subscriber syncs her Compact Edition database it downloads 10 rows - the proper 4 rows that the filter statement should pass, plus 6 other rows that she should not download. Our hypothesis is that the Filter statement is not properly applied to the article when this subscriber syncs. Other subscribers get the proper rows when they sync, so the publication's filter statement works in some cases, for some values of Host_Name(). We'd like to see the application of the filter statement at run-time (sync-time), but we have not found the text of the filter statement in SQL Profiler output. Should we expect to see the text of the filter statement in SQL Profiler output? Is there a better way to debug this error? FYI, here's the text of the article filter statement: SELECT <published_columns> FROM [dbo].[TBL_USER] WHERE user_sys_id in ( select u.user_sys_id from tbl_user u join tbl_territory t on u.territory_gid = t.territory_gid where t.terr_no_id like ( select case (select t.data_access_qnty from tbl_user u join tbl_territory t on u.territory_gid = t.territory_gid where u.user_sys_id = Host_Name()) when 2 then (select t.terr_no_id from tbl_user u join tbl_territory t on u.territory_gid = t.territory_gid where u.user_sys_id = Host_Name()) when 3 then (select left(t.terr_no_id,5)+'%' from tbl_user u join tbl_territory t on u.territory_gid = t.territory_gid where u.user_sys_id = Host_Name()) end ) ) And here's the statement we ran from Query Analyzer: declare @id varchar(10) select @id = 'aultnc' SELECT * FROM [dbo].[TBL_USER] WHERE user_sys_id in ( select u.user_sys_id from tbl_user u join tbl_territory t on u.territory_gid = t.territory_gid where t.terr_no_id like ( select case (select t.data_access_qnty from tbl_user u join tbl_territory t on u.territory_gid = t.territory_gid where u.user_sys_id = @id) when 2 then (select t.terr_no_id from tbl_user u join tbl_territory t on u.territory_gid = t.territory_gid where u.user_sys_id = @id) when 3 then (select left(t.terr_no_id,5)+'%' from tbl_user u join tbl_territory t on u.territory_gid = t.territory_gid where u.user_sys_id = @id) end ) ) Thanks

How To Iterate Through Table Variable Without Using Cursor

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.

Here is the statement: Create Procedure sp_InfoDump ( @StartDate varchar(12), @EndDate varchar(12), @OrderBy varchar(50) ) As /* Local variables */ DECLARE @MinDate datetime, @MaxDate datetime IF @StartDate = 'ALL DATES' BEGIN SELECT @MinDate = Min(AccessTime) FROM tblAudit END ELSE BEGIN SELECT @MinDate = @StartDate END IF @EndDate = 'ALL DATES' BEGIN SELECT @MaxDate = Max(AccessTime) FROM tblAudit END ELSE BEGIN SELECT @MaxDate = @StartDate END BEGIN SELECT tblReports.ReportName, tblReports.ReportCode, tblAudit.BadAttempts, tblAudit.LogonUser, tblAudit.AccessTime, tblAudit.RemoteHost, tblAudit.RemoteIdent, tblAudit.ExitTime, tblAudit.BrowserType, tblAudit.Access_ID, TotalTime=DateDiff(Minute,tblAudit.AccessTime,tblA udit.ExitTime) FROM tblReports INNER JOIN tblReportsAccess ON tblReports.Report_ID = tblReportsAccess.Report_ID INNER JOIN tblAudit ON tblReportsAccess.Audit_ID = tblAudit.Audit_ID WHERE tblAudit.AccessTime >= @MinDate AND tblAudit.AccessTime <= @MaxDate ORDER BY (SELECT 'ColumnName'=ColumnName FROM tblOrderBy WHERE ColumnName = @OrderBy) END RETURN

Using A @Variable As An IN Clause Expression
Is there a good way to use a @variable in a Stored procedure to represent the expressions for an IN clause I.e. I need to accomplish the following: Create Procedure sp_ABC @Variable VarChar (1024) AS Select * From tblAnyTable Where intTableID IN (@Variable) Is there a valid way to accomplish this? The above code presented here does not work, because the VarChar cannot be translated into int.

CONTAIN Clause Not Taking A Variable?
Hi, I created a full-text catalog on a table and ran a contain clause against it with a declare variable on the search. Example.... DECLARE @chrClause VARCHAR(204) SET @chrClause = ' "XXXX" ' SELECT ID FROM Emp WHERE CONTAINS(Tax_Nam, @chrClause) I'm getting an error that says... Line 8: Incorrect syntax near '@chrContainClause'. Is this a problem i can fix by applying SP3?

Output Of Select Stament Into Variable Within Cursor
Within a cursor that I am building I would like to execute a select statement built from a varchar variable as such: SELECT @BuildDBPageUsed = 'SELECT sum(reserved) FROM ' + @DatabaseName + '.dbo.sysindexes WHERE segment <> 2' Next I execute the statement, which is now in the variable @BuildDBPageUsed. Such as: EXEC (@BuildDBPageUsed) The resulting output I need to set to another variable @DBPageUsed which is integer. I have been unsuccessful in finding the correct set of commands to do this. How should I build the command to input the results of the EXEC (@BuildDBPageUsed) into the integer variable @DBPageUsed? *Thanks* for any help in this matter. Brad

Use A Variable Along With The FROM Clause In SELECT Statement
I have a table 'table_list' which contains two columns, table_name and a record_count. This table stores a list of tables and their corresponding record counts. What I am trying to do is, to be able to write a select statement, that can read each table name in the 'table_name' column, execute a select count(*) for the same, and update its record_count with the result of select count(*). This is the code in my procedure.. DECLARE @tab_list CURSOR set @tab_list = CURSOR FOR select * from table_list OPEN @tab_list DECLARE @tab_name varchar(256) DECLARE @rec_cnt int FETCH NEXT FROM @tab_list INTO @tab_name, @rec_cnt select count(*) from @tab_name This select is looping around along with FETCH till all the table names are exhausted and their counts are updated from the cursor back into the table. Problem is that, I am not able to use select count(*) from @tab_name, and its not accepting a variable there. Please help me to construct the select statement that is similiar to x=<table name> select * from x where x is a variable and the table name gets substituted. what is the syntax for it ?

Question About Assigning Cursor Variable Data Types...
Hi, I'm just curious about something...when assigning a datatype to a cursor variable in ORACLE, you can use the keyword TYPE to automatically grap the datatype from the associated column (or use ROWTYPE to create a cursor variable to represent an entire row in a table). It's so much easier and if the datatype of one of the cursor columns is altered, the associated cursor variable assumes the new datatype. Is there a way to do this in SQL Server 7.0 ? many thanks :)

Passing Variable To Where Clause In Sql Query From A Grid
Hi everyone I am new to this site I have a major issue I cant figure out seeing how im fairly new to asp, and vb, but i have 5 years php mysql experience. Im pulling the correct data into a grid. Then i need to make a button or some sort of link that will take the value of one field in the record set and replace it with @transid in the where statement I can enter in the value of transid into form field with that name and it will run the rest of the script correctly, I just cant get past this hurdle. If anyone can help that would be great. I tried to get this to work with java script but then realized thats not possible to transfer varaibles to asp from it. ///javascript function DisplayReciept(transactionnum) { recieptdis = transactionnum; } ////field in grid <asp:BoundField htmlEncode=false DataFormatString="<a href=javascript:DisplayReciept{0}>Display</a>" DataField="transid" HeaderText="Show Reciept" SortExpression="transid" /> //////////////query////////////// <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:dbsgcConnectionString %>" SelectCommand="SELECT [fulldata] FROM [data] WHERE ([transid] = @transid)"> <SelectParameters> <asp:FormParameter FormField="transid" Name="transid" Type="Int32" /> </SelectParameters> </asp:SqlDataSource>

Using A Stored Procedure Variable To Define A Where Clause
Hi all, I'm trying to build a Where clause in a stored procedure based on the information that is passed into the stored procedure. Because I don't know how many items will be passed into the stored procedure, I'm having to split the string on a specific character and build the Where clause based on how many strings are found. However, when I try to execute the Where clause it throws an error. Code Snippet ALTER PROCEDURE getUsersAddress -- Add the parameters for the stored procedure here @LName varchar(1000) @City varchar(1000), @State varchar(1000), @License varchar(1000) AS declare @Count as int declare @x as int declare @wLName as varchar(2000) declare @wCityas varchar(2000) declare @wStateas varchar(2000) declare @wLicense as varchar(2000) BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; if right(rtrim(@LName),1) <> ';' begin set @LName = @LName + ';' end set @Count = PATINDEX('%;%',@LName) set @wLName = '(tblUsers.LName = ''' while @Count <> 0 begin set @wLName = @wLName + left(@LName, @Count - 1) set @LName = stuff(@LName, 1, @Count, '') set @Count = PATINDEX('%;%',@LName); if @Count <> 0 begin set @wLName = @wLName + ''') OR (tblUsers.LName = ''' end else begin set @wLName = @wLName + ''')' end end print cast(@wLName as varchar(5000)) -- Insert statements for procedure here SELECT tblUsers.FullName, tblUsers.Addy1, tblUsers.Addy2, tblUsers.City, tblState.StateAbbr, tblUsers.Zip, tblUsers.Zip4 FROM tblUsers INNER JOIN tblState ON tblUsers.FK_StateID = tblState.StateID INNER JOIN tblUserDetails ON tblUsers.UserID = tblUserDetails.FK_UserID WHERE (@wLName) OR (tblUsers.City = @City) OR (tblState.StateAbbr = @State) OR (tblUserDetails.CDLType = @License) END So when I print do an exec getUsersAddress 'Johnson;Smith', 'City;Test City', 'TX;OK', 'Class A;Class B' @wLName comes out as (tblUsers.LName = 'Johnson') OR (tblUsers.LName = 'Smith') However, I can't save the procedure as it gives me an error of: An expression of non-boolean type specified in a context where a condition is expected, near 'OR'. When I copy and paste the @wLName value in place of @wLName in the Where clause it works, so how can I get the @wLName variable to work in that Where clause?

Dynamic Query, Local Cursor Variable And Global Cursors
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

And/or Filter Field Not Enabled In The Group Filter Tab
Howdy, I have a table that has a group. In this group, I want to filter by 2 different expressions, concatenated with an OR. BUT I can't change the "And/Or" column value for the first entry because it is grayed out. The column will automatically change to an OR value if both my expression column fields are the same (which I don€™t want) but if I put any other value in to the expression field of the second row, the "And/Or" field of the first row automatically changes to an AND. PLEASE! How do I get the And/Or field "ungrayed" so I can change it to what I want? The 2 filters I and using check the UserID = to the user, and the other is checking a count to get the Top N 1. (So just showing the current user and the top producer)

Automatic Select Filter (something Like &&"global Table Filter&&")
Hello, Here is my problem: I use SQL Server 2005. I have approx. 50 tables in my database and 30 of them have a filed named "CompanyID". Example: create table A (ID int identity, NAME varchar(100), COMPANYID int)create table A (ID int identity, REF_ID int, FIELD1 varchar(100), FIELD2 varchar(100), COMPANYID int) Also there are nearly 200 stored procedures that read data from these tables. Example: create procedure ABCasbegin /* some checks and expressions here ... */ select ... from A inner join B on (A.ID = B.REF_ID) where ... /* ... */end; All my queries in the Stored procedure does not filter the tables by CompanyID, so they process the entire data. However, now we have a requirement to separate the data for each company. That means that we have to put a filter by CompanyID to each of those 20 tables in each query where the tables appear. Firstly, I put the CompanyID in the context so now its value is accessible through the context_info() function. Thus I do not need now to pass it as a parameter to the stored procedures. However, I don't know what is the easiest and fastest way to filter the tables. Example: I modified the above mentioned procedure in the following way: create procedure ABCasbegin /* some checks and expressions here ... */ -- gets the CompanyID from the context: DECLARE @CompanyID int; SELECT @CompanyID = CONVERT(float, CONVERT(varchar(128), context_info())) select ... from A inner join B on (A.ID = B.REF_ID) where ... and A.COMPANYID = @CompanyID and B.COMPANYID = @CompanyID /* ... */end; Now I have the desired filter by CompanyID. However, modifying over 200 stored procedures is rather tedious work and I don't think that this is the best approach. Is there any functionality in SQL Server that can provide the possibility to put an automatic filter to the tables. For example: when I wrote "SELECT * FROM A", the actual statements to be executed would be "SELECT * FROM A WHERE CompanyID = CONVERT(float, CONVERT(varchar(128), context_info()))". I was looking for something like "INSTEAD OF SELECT" triggers but I didn't manage to find any answer. I would very grateful is someone suggests a solution for something like "global table filter" (that will help me make an easy refactoring)? Thanks in advance. Best regards, Beroetz

Dynamic Cursor Versus Forward Only Cursor Gives Poor Performance
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
