Cursor Vs. Select
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

Basically, I want to do this: SELECT data3, data4 INTO variable1, variable 2 FROM table WHERE data1= textbox1.text, data2 = textbox2.text I am pulling data based on a selection of name (data1) and date (data2).

Using Variables In A SELECT Query
Hi I'm a n00b at ASP.Net and C# but the company I work for requires me to know this and develop their website using these languages. Anyway I've been doing pretty good so far I got the page looking as it should etc and databases all set up, now I've hit my first real problem... I am using Visual Studio 2005 and in the Web Developer section. I want to make a SELECT query using the <asp:LoginName> control as the where clause. e.g. if admin logs in there is a welcome message : Welcome Admin now I want to use the 'Admin' <asp:LoginName> as the SELECT in my query i.e. SELECT * FROM tbla WHERE ([fldCustomerCode] = 'LoginName' ) I was just really wondering if that is in the .aspx file or the aspx.cs code behind file?

Use Variables Or Multiple SELECT's?
Stored procedure retrieves a single row from a single table... Based on the specific values in 4 different columns, different branch actions are taken using 4 nested IF statements. The question is, what is more efficient: storing column values in 4 variables and then evaluting each of them, or executing the same query 4 times? Scenario A: DECLARE @var1 char(20), @var2 char(20), @var3 char(20), @var4 char(20) SELECT @var1 = col1, @var2 = col2, @var3 = col3, @var4 = col4 FROM theTable WHERE rid = 12345 IF @var1 = 1 ... ELSE IF @var2 = 2 ... ELSE IF @var3 = 3 ... etc. --------------- Scenario B: IF (SELECT col1 FROM theTable WHERE rid = 12345) = 1 ... ELSE IF (SELECT col2 FROM theTable WHERE rid = 12345) = 2 ... ELSE IF (SELECT col3 FROM theTable WHERE rid = 12345) = 3 ... etc. -------- Scenario A or B? Please advise... TIA, Alex

Select With Cascading Variables
Is there a way to write an insert where the values you're inserting depend on another value in the row. Here is an example of pseudo-code that hopefully demonstrates what I'm tryihg to do: declare @k1 varchar(100) declare @k2 varchar(100) declare @k3 varchar(100) insert into tbl2 select field1, field2, field3, @k1=(select sm from tbl3 where mm=field1), @k2=(select sm from tbl3 where mm=@k1), @k3=(select sm from tbl3 where mm=@k2) from tbl1 where blah= blahblah and bldfddf = dfaljk My main focus is using the variables @k1 - @k2 in the where part of subsequent subqueries in the select statement. I haven't been able to get this to work, but I thought maybe something like it would work. I'd like to do this in one statement rather than using a cursor or loop. I'm also trying to avoid functions. Any help would be appreciated.

Variable As Column In Cursor Select
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????

How To Specify Which Database To Use For A Select Statement Within A Cursor?
Hi everyone, I have been trying to perform the following task: Using the sys.databases & sys.sysindexes views to display all the columns with a clustered index for all tables and all databases in a given server. So the end result will have 3 columns: Database name Table name Column name from that table with a clustered index I have already created the following script which displays all the databases for a given server: declare @DBname nvarchar(128) declare testCursorForDB cursor for select name from sys.databases with (nolock) where name not in ('master','tempdb','model','msdb') order by name open testCursorForDB fetch next from testCursorForDB into @DBname while @@fetch_status = 0 begin print @DBname fetch next from testCursorForDB into @DBname end close testCursorForDB deallocate testCursorForDB I also have created the following query which will display all the table and column names which have a clustered index for a given database: select object_name(i.id) as TableName, i.name as IndexName from sys.sysindexes as i with (nolock) where i.indid = '1' However, what I need help/advice on is how do I combine these two together into one working script (either using nested cursors or a better way). In other words, how can I specify which database to use (ie. using the "use database_name") so that my query above will be applied to each database found within the cursor.

Incrementally Build Cursor Select Using CASE?
In Access/VB/DAO I can declare a string variable to contain my SELECT statement. If I do this I can build the string incrementally and finally open the cursor using OpenRecordset(strSQL). I'd like to be able to do this in SQL7. Let me illustrate: In Access97: Function Test(ByVal pstrOrder As String) As Boolean Dim strSQL As String strSQL = "SELECT * FROM tblEmployee " Select Case pstrOrder Case "Alpha" strSQL = strSQL & "ORDER BY [LastName], [FirstName]" Case "SSN" strSQL = strSQL & "ORDER BY [SSN]" End Select db.OpenRecordset(strSQL) End Function This is a very simple example....I have a lot of complex SELECT statements and I don't want to retype the same code in the same procedure that does ALMOST the same thing. I'm hoping to use something like the CASE construct: DECLARE csrEmployee CURSOR FOR SELECT * FROM tblEmployee (CASE @pstrOrder WHEN "Alpha" THEN ORDER BY LastName, FirstName WHEN "SSN" THEN ORDER BY SSN END) Can anyone out there help?

So, I'm trying to retrieve from a table, with a sql stored procedure with the sql like "select height, width, depth from products where id=@idinput" OK, so this part is easy, but if I wanted to say, return this to my code and assign height to a variable Ht, width to Wd and depth to Dp, how could I do that? This is what I've got so far... [code] cmdSelect = New SqlCommand( "GetProd", connstr ) cmdSelect.CommandType = CommandType.StoredProcedure dbcon.Open() dbcon.Close() [/code] The main prob is just what to connect this record to in order to access the individual fields.

The above date is part of the table for a ProductID . (The field is removed here) In order to calculate the balance amount using moving average, I must calculated the cost_out_amt first on the fly. When user add new sales I also need to determine the cost/unit for a product id using moving average. The problem is I can not just use sum, because i need to determine cost_out_amt for each sales first which will be calculated on the fly. The reason i dont store the cost_out_amt (instead calculate on the fly) because User could Edit the previous sales/purchase txn or Insert new sales for a previous date. Example THe record with ID 9. By Adding this txn with ID 9, would cause all the cost_out_amt will be incorrect (Using moving Average) if i store the cost_amout_out on entrying txn and need to be recalculated. Instead I just want to calculate on the fly and able to determine the cost avr for a specific point of time. Should I just use Cursor and loop all the record and calculate the cost or maybe I can just use on Select Statement?

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

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

Execute DTS 2000 Package Task Editor (Inner Variables Vs Outer Variables)
Hi, I am not comfortable with DTS 2000 but I need to execute a encapsulated DTS 2000 package from a SSIS package. The real problem is when I need to pass SSIS variables to DTS 2000 package. The DTS 2000 package have 3 global variables that I can identify on " Execute DTS 2000 Package Task Editor - Inner Variables ". I believe the SSIS variables must be mapped on " Execute DTS 2000 Package Task Editor - OuterVariables ". How can I associate the SSIS variables(OuterVariables ) to "Inner Variables"? How can I do it? Much Thanks. João

How To Design A Package With Variables So That I Can Run It By Dos Command Assigning Values To Variables?
Hi, I would like to design a SSIS package, which have couple of variables. It loads a xls file specified in a variable [varExcelFileFullPath] . I will run it by commands: exec xp_cmdshell 'dtexec /SQL ....' (pls see an example below). It seems it does not get the values passed in for those variables. I deployed the package to a sql server. are there any grammar errors here? I copied it from dtexecui. It worked inside Dtexecui not in dos command. exec xp_cmdshell 'dtexec /SQL "LoadExcelDB" /SERVER test /USER *** /PASSWORD **** /MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING EW /LOGGER "{6AA833A1-E4B2-4431-831B-DE695049DC61}";"Test.SuperBowl" /Set Package.Variables[User::varExcelFileName].Properties[Value];"TestAdHocLayer" /Set Package.Variables[User::varExcelWorkbookName].Value;"Sheet1$" /Set Package.Variables[User::varExcelFileFullPath].Value;"D: estshareTestAdHocLayer.xls" /Set Package.Variables[User::varDestinationTableName].Value;"FeaturesTmp" /Set Package.Variables[User::varPreSQLAction].Value;"delete from FeaturesTmp" ' thanks, Guangming

Client Side Cursor Vs Sever Side Cursor?
I having a difficult time here trying to figure out what to do here.I need a way to scroll through a recordset and display the resultswith both forward and backward movement on a web page(PHP usingADO/COM)..I know that if I use a client side cursor all the records get shovedto the client everytime that stored procedure is executed..if thisdatabase grows big wont that be an issue?..I know that I can set up a server side cursor that will only send therecord I need to the front end but..Ive been reading around and a lot of people have been saying never touse a server side cursor because of peformance issues.So i guess im weighing network performance needs with the client sidecursor vs server performance with the server side cursor..I am reallyconfused..which one should I use?-Jim

Is This Possible Without A Cursor?
I have something like update table set field = ... where field = ... and for each entry that was effected by this query I want to insert an entry into another table. I have always done this with cursors is there a more effecient way? For some reason cursors run a lot slower on my sql2005 server than the sql2000 server...

Need Help With A Cursor
I hope this is the appropriate forum for this question, if not then I apologize. I've got a SQL Server 2000 stored procedure that returns data to be used in a crystal report in Visual Studio 2005. Most of the stored procedure works well, but there is a point where I need to calculate an average number of days been a group of date pairs. I'm not familiar with cursors, but I think that I will need to use one to achieve the result I am looking for so I came up with the code below which is a snippet from my stored procedure. In this part of the code, the sp looks at the temporary table #lmreport (which holds all of the data that is returned at the end to crystal) and for every row in the table where the terrid is 'T' (the territory is domestic), it selects all of those territories from the territory table and loops through them to determine the date averages (by calling a nested stored procedure, also included below) for each territory and then updates #lmreport with that data. When I try to run the stored procedure, I get "The column prefix '#lmreport' does not match with a table name or alias name used in the query." on the line indicated. Does anyone have any idea what might be wrong or if this will even work the way I need it to? Thank you in advance.
