Dynamic Cursor/ Dynamic SQL Statement
I've looked up Books Online on Dynamic Cursor/ Dynamic SQL Statement.
Using the examples given in Books Online returns compilation errors. See below.
Does anyone know how to use Dynamic Cursor/ Dynamic SQL Statement?

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

Using A &"dynamic Top&" Statement With A Cursor
Help please,Have a situation when converting from Oracle SP's to SQL SP's. The oldoracle cursor was roughly as followsCURSOR cur_rsStock ISselect*from(select StockRowId, CategoryIdfromSTOCKDISPOSABLEwhereSTOCKDEFID=numDefIdORDER BYSTOCKROWID)whereROWNUM <= numQuantity;The closest I can get in MS SQL is as follows :declare cur_rsStockCURSOR forselect top @numQuantityStockRowId, CategoryIdfromSTOCKDISPOSABLEwhereSTOCKDEFID=numDefIdORDER BYSTOCKROWIDBut, SQL doesn't allow variables next to top. 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

Dynamic Execution Of Cursor Fetch
I'm trying to write code which will fetch records from a dynamically created cursor. Therefore the cursor name is not known at design time. Unfortunately applying an enclosing the fetch command in quotes and then calling the execute method with this string will not work. e.g. declare @A varchar(10), @B varchar(10), @sFetch varchar(255) --Open the cursor Execute ('Open ' + crAnyCursor) --create fetch string Select @sFetch = 'Fetch Next From' + crAnyCursor + 'into @A, @B' execute (@sFetch) The following error is returned... Msg 137, Level 15, State 1 Must declare variable '@A'. Is there another means of working with dynamically executed cursors? Thanks JohnG

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

Importing Excel Sheet Which Have Dynamic Column Name And Dynamic Number Of Columns
Hi Craig/Kamal, I got your email address from your web cast. I really enjoyed the web cast and found it to be very informative. Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question regarding the product. I have looked for the information on the web, but was not able to find relevant information. We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets Are generated using reporting services. On examining the excel sheet, I found out that the name Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc. And even the number of columns are not static. It depends upon the range of date selected by the user. I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic Number of columns. Your help in this respect is highly appreciated! Thanks, Hi Anthony, I am glad the Web cast was helpful. Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using. I suggest you post a question on the SSIS forum on MSDN and you should get some good answers. http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1 http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1 Thanks Craig Guyer SQL Server Reporting Services

SSRS 2005 - Email Report On Execution To Dynamic List With Dynamic Parameters = No Schedule
Hi, I have a need to display on screen AND email a pdf report to email addresses specified at run time, executing the report with a parameter specified by the user. I have looked into data driven subscriptions, but it seems this is based on scheduling. Unfortunately for the majority of the project I will only have access to SQL 2005 Standard Edition (Production system is Enterprise), so I cannot investigate thoroughly. So, is this possible using data driven subscriptions? Scenario is: 1. User enters parameter used for query, as well as email addresses. 2. Report is generated and displayed on screen. 3. Report is emailed to addresses specified by user. Any tips on how to get this working? Thanks Mark Smith

Merge Replication W/ Dynamic Row Filter - Not 'dynamic' After First Initial Sync?
If anyone could confirm... SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter. E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere. First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided. However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change. Question: I thought the filters would remain dynamic and be applied on each sync? I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not! Question: I wonder why if parent records are supplied, why not child records? If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server... Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?

Dynamic SQL Statement
I am trying to write a dynamic sql insert statement in c#, but given this is my first run at creating sql statements dynamically I am having issues. My reason for creating the sql statement dynamically is because I do not want to insert any items that are null. Will I have to have a separate string for each section of the statement? For example:sql1 = "Insert Into Table [test]";sql += "(Column1, Column2, Column3," ;sql2 = "Values" ;sql2 += "(field1, field2, field3"; and then a third section if I were to use parameters. My thinking here is how do you append to a string in numerous locations? I will populate the sql strings first with those columns and fields that I know will not be null, and then use if statements to add to each sql string if the field in question != null. in other words, little help.

How Do You Build A Dynamic WHERE Statement?
I have 5 drop down lists and 1 text box, and I need to build the WHERE portion of my SELECT statment (stored procedure). the drop down lists are named client, ptype, apptdate, inspdate, state, and the textbox is named text. they all need to be this=something AND that=another AND...AND text LIKE mytext. How would I go about building this efficiently? Would I Declare a bit value in the sp called WhereSet = 0 IF @client IS NOT NULL IF @WhereSet = 0 SET @Where = 'WHERE ClientID=@client' SET @SetWhere = 1 ELSE SET @Where = @Where + ' AND CleintID=@client' . . .... Or would this be a lot easier using adhoc SQL instead of a Stored Procedure? (note: I am using a SQL DataSource) Please help, I am going bald from pulling my hair our...

Cannot Run Dynamic Sql Using 'USE DB_Name' Statement
For whatever reason, the following when executed does not take the context of the supplied Database name. Any ideas as to why? More importantly is there a work around. I am trying to create a database level batch job. declare @sql nvarchar(100) set @sql = 'USE Northwind' print @sql EXEC sp_executesql @sql Thanks, Mark

Dynamic Update Statement
I have a table to process, with up to six data items. It has a matching record in another table which matches by an id field that will be update by this transaction record. Any combination of the items may have data in them, but if the field is blank we do not want to update the matching records data items, only ones that have data. I was thinking of creating a dynamice tsql statement created by some case statements, that check the length of the 6 data items. It sounds a little hairy but will probably work. Any better approaches?

Mixing Dynamic SQL With Non-Dynamic In Stored Proc
I have a Stored Procedure for processing a Bill of Material. One column on the Assembly Table is a Function Name that contains some busniess rules. OK, now I'm doing a Proof of Concept and I'm stumped. Huuuuh! I will ultimately have about 100 of these things. My plan was using Dynamic SQL to go execute the function. Note: The function just returns a bit. So; here's what I had in mind ... if isnull(@FnNameYN,'') <> '' exec spinb_CheckYN @FnNameYN, @InvLineID, @FnBit = @FnBit output CREATE PROCEDURE dbo.spinb_CheckYN @FnNameYN varchar(50), @InvLineID int, @FnBit bit output AS declare @SQL varchar(8000) set @SQL = ' if dbo.' + @FnNameYN + ' (' + convert(varchar(31),@InvLineID) + ')) = 1 set @FnBit = 1 else set @FnBit = 0' exec (@SQL) GO Obviously; @FnBit is not defined in @SQL so that execution will not work. Server: Msg 137, Level 15, State 1, Line 4 Must declare the variable '@FnBit'. Server: Msg 137, Level 15, State 1, Line 5 Must declare the variable '@FnBit'. So; is there a way to get a value out of a Dynamic SQL piece of code and get that value INTO my OUTPUT variable? My many thanks to anyone who can solve this riddle for me. Thank You! Sigh: For now, it looks like I'll have a huge string of "IF" statements for each business rule function, as follows: Hopefully a better solution comes to light. ------ Vertical Build1 - Std Vanes ----------- if @FnNameYN = 'fnb_YN_B1_14' BEGIN if dbo.fnb_YN_B1_14 (convert(varchar(31),@InvLineID) ) = 1 set @FnBit = 1 else set @FnBit = 0 END ------ Vertical Build1 - Scissor Vanes ----------- if @FnNameYN = 'fnb_YN_B1_15' BEGIN if dbo.fnb_YN_B1_15 (convert(varchar(31),@InvLineID) ) = 1 set @FnBit = 1 else set @FnBit = 0 END . . . etc.

Dynamic Select/Update Statement Possible?
Would it be possible to retrieve a "dynamically" named field from a table by using an input parameter? For example, if a table has fields named Semester1, Semester2, Semester3, Semester4, and I was lazy and only wanted to create one stored procedure for all semesters could I do the following... ALTER PROCEDURE u_sp_x @semester int AS Select Semester@semester From ThisTable Just curious. Thanks, Steve Hanzelman

Dynamic Statement In Variable - Parseerror
I am trying to use this statement in a variable, including another variable: "SELECT * FROM my_table WHERE CAST([timestamp] AS INT) > " + @[User::LastTimestamp] But the variable value insists on giving me this error: The expression for variable "VariableName" failed evaluation. There was an error in the expression. I cast the columntype "timestamp" to int, and the variable "LastTimestamp is stored as int32, and has a default value of 0. I simply can't grasp what it is I am missing. Is it because the expression is part string and part integer? If so, how is that avoided? Thanks in advance

Building A Dynamic Sql Statement Into Stored Procedure
Hi i have a page whereby the user can make a search based on three things, they are a textbox(userName), dropdownlist(subcategoryID), and region (regionID). The user does not have to select all three, he or she can enter a name into the textbox alone and make the search or enter a name into the textbox and select a dropdownlist value, my question is how can i build this procedure, this is what another user suggested but i am having trouble; ALTER PROCEDURE [dbo].[stream_UserFind] ( @userName varchar(100), @subCategoryID INT, @regionID INT )AS declare @StaticStr nvarchar(5000)set @StaticStr = 'SELECT DISTINCT SubCategories.subCategoryID, SubCategories.subCategoryName,Users.userName ,UserSubCategories.userIDFROM Users INNER JOIN UserSubCategories ON Users.userID= UserSubCategories.userIDINNER JOINSubCategories ON UserSubCategories.subCategoryID = SubCategories.subCategoryID WHERE UserName like @UserName' if(@subCategoryID <> 0) set @StaticStr = @StaticStr + ' and SubCategories.subCategoryID = @subCategoryID 'if(@regionID <> 0) set @StaticStr = @StaticStr + ' and SubCategories.RegionId = @regionID ' exec sp_executesql @StaticStr )

Spooky Semi-dynamic Sql Update Statement
Hi, I rewrote my working Sql statement to prevent Sql Injections. I copied some code I used in another project but this time I can't get it to work, possibly because it's an update statement and not an Insert one, which I used before. Sorry for the boring question, but does anyone have a clue what's wrong with the syntax? Here's the original code (I changed the parameter names for clarity and security): Dim conn As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString) Dim strSQL As String = "Update MyTable Set " & typ & num & " = '" & pname & "' WHERE personID = " & fid Dim cmd As SqlCommand = New SqlCommand(strSQL, conn) Here's the code from codebehind: Dim conn As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString) Dim strSQL As String = "Update MyTable Set (" & typ & num & ") Values (@" & typ & num & ") WHERE personID = " & fid Dim cmd As New SqlCommand(strSQL, conn) With cmd.Parameters .Add(New SqlParameter("@" & typ & num, pname)) End With TestLabel.Text = strSQL & " " & pname cmd.Connection.Open() cmd.ExecuteNonQuery() cmd.Connection.Close() Here's my test message; first the sql, then the new string to be inserted: Update MyTable Set (picturename) Values (@pname) WHERE personID = 2 2_adin.jpg Here's my error code: Line 1: Incorrect syntax near '('. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near '('. Source Error: Line 489: TestLabel.Text = strSQL & " " & pnameLine 490: cmd.Connection.Open()Line 491: cmd.ExecuteNonQuery()Line 492: cmd.Connection.Close()Line 493: End If I could understand it if I'd get an error in VWD Express for using dynamic variables, but they work correctly in the text message so I'm clueless. Any help is deeply appreciated! Pettrer (VB, Sql Server 2000)

SQL Statement For Querying Data With Dynamic Fields
I am working on a project in which a customer wants to be able to list and search their inventory and display the items in a table/grid on a web page.Each item in their inventory has a set of properties - for example, manufacturer, price, serial number, name, etc. The complicated part is that they want an admin to be able to modify/add/delete the set of properties. So for example, they could add the attribute "size." Given that, I think what is needed is 3 tables - one to store the set of properties schema, one for the items, and one to store the actual properties for each item. I know i COULD use alter table statements to add and delete columns, but that doesn't seem like the "right" solution.I would like to be able to write a query such that each row returns the item and all its properties - then i can easily bind to a datagrid. However, what would the query be to do this? I also need to be able to allow the customer to query for items with certain properties - i imagine the sql for that to be similar to this:SELECT * FROM items d WHERE d.Id IN(SELECT a.ItemId FROM attributes a WHERE a.Name = "Manufacturer" AND a.Value = "Samsung") AND d.Id IN(SELECT a.ItemId FROM attributes a WHERE a.Name = "SerialNumber" AND a.Value = "3223")

Dynamic Create Table Statement Or SELECT INTO
In SQL Server you can do a SELECT INTO to create a new table, much like CREAT TABLE AS in Oracle. I'm putting together a dynamic script that will create a table with the number of columns being the dynamic part of my script. Got any suggestions that come to mind? Example: I need to count the number of weeks between two dates, my columns in the table need to be at least one for every week returned in my query. I'm thinking of getting a count of the number of weeks then building my column string comma separated then do my CREATE TABLE statement rather then the SELECT INTO... But I'm not sure I'll be able to do that using a variable that holds the string of column names. I'm guess the only way I can do this is via either VBScript or VB rather then from within the database. BTW - this would be a stored procedure... Any suggestions would be greatly appreciated.

Dynamic Column Names In Select Statement
I have a quick question on SQL Server. Lets say I have table Order which has column names OrderId, CustomerName, OrderDate and NumberofItems. To select the OrderID values from the table I say Select OrderId from Order. But in the select if I want the column name to be variable how do I do it. I tried the following code through a stored procedure. declare @order_id nvarchar(10) select @order_id = 'OrderID' SELECT @order_id from Order. The code above gave me the string "OrderID" as many times as there were rows in the table but I could never get the actuall values in the OrderId column. Can you please send me some ideas or code where I can get values from the column names and at the same time change the column name dynamically.

Looping Insert Statement With Dynamic Var Names...help...
672.1 I have a form that's sending 5 values, from form fields named "option1","option2" etc., to my SQL Server 7 DB. I want to loop through and insert each one into the table in my stored procedure. So I'm starting with: CREATE proc usp_upd_question @question_ID int output, @option1 varchar(255), @option2 varchar(255), @option3 varchar(255), @option4 varchar(255), @option5 varchar(255) as set nocount on declare @counter integer set @counter=1 while (@counter < 6) begin insert into question_options (question_ID, option_text) values (@question_ID, HERE'S MY PROBLEM!) set @counter=@counter+1 end Basically, I need some way to send the var ("option"+@counter) into the insert. I can get that string no problem, like set @thisoption='option'+cast(@counter as varchar(5)) ...but then it's a string, and I can't figure out how to get the DB to take that strong and look at it as though it were a variable. Anyone got any bright ideas? i'm sort of new at this SQL stuff. Thanks, Al

Dynamic CASE Statement Based On List Of Dates
I have the following table of data. I need to take a date from a large table and do the following case:CASEWhen date < date(0) Then '0'When date between date(0) and date(1) Then '1'When date between date(1) and date(2) Then '2'When date >= date(3) Then '3'What I need is to be able to read all the dates the the Date table, sort then chronologically, and build the dynamic CASE statement so that the first When statement is < Date(0) and the last When statement is >= Date(Last)I hope I am making sense. Dates will be added to the table about once a year or so and I don't want to keep going back into the sql function and rewrite it with the latest date. Any ideas how to manipulate these dates into a case statement? Don't worry about the second table below. I just wanted you to see why I need to return an int from the Case function.thanksMilton Dates Table Date 4/1/2003 1/1/2006 4/2/2007 Fee Table Date Period Class Fee 1 Daily True 329 1 Half Day True 178 1 OT True 49 1 Hourly True 41 1 Daily False 156 1 Half Day False 86 1 OT False 27 1 Hourly False 19 2 Daily True 355 2 Half Day True 192 2 OT True 50 2 Hourly True 44 2 Daily False 171 2 Half Day False 92 2 OT False 28 2 Hourly False 21 3 Daily True 364 3 Half Day True 197 3 OT True 51 3 Hourly True 45 3 Daily False 175 3 Half Day False 94 3 OT False 29 3 Hourly False 21
