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.
Mirko.

Set Value For Variable In A Declared Cursor
Hi, 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. ------------------------------------------------------------------------ DECLARE @str_var VARCHAR(10) DECLARE @field_val VARCHAR(10) DECLARE c1 CURSOR LOCAL FOR SELECT field1 FROM tableA WHERE field1 = @str_var WHILE (Sometime TRUE) BEGIN .... SET @str_var = 'set to some values, eg. ABC123, XYZ123' OPEN c1 FETCH c1 INTO @field_val WHILE (@@fetch_status != -1) BEGIN PRINT @field_val ... FETCH c1 INTO @field_val END CLOSE c1 END DEALLOCATE c1 ---------------------------------------------------------------------- Thanks a lots, Vincent

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

Passing A SSIS Global Variable To A Declared Variable In A Query In SQL Task
I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task: DECLARE @DV INT; SET @DV = (SELECT MAX(DateValue) FROM tblTG); DECLARE @PV INT; SET @PV = @DV - 1; I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this: DECLARE @DV INT; SET @DV = ?; DECLARE @PV INT; SET @PV = @DV - 1; I have almost 50 references to these parameters in the query so a substitution would be helpful.

Stored Procedure Using A Declared Cursor
I need to write a stored procedure using T-SQL to declare a cursor for containing id(staff_no), names and specialism of all doctors that have specialism, The contents of the cursor then are to be displayed using a loop and print statement to give a formatted display of the output of each record within the cursor. The doctors table has the following columns with specialism allowing NULL values doctor ( staff_no CHAR(3), doctor_name CHAR(12), position CHAR(15), specialism CHAR(15), PRIMARY KEY(staff_no) ) Any help would be greatly appreciated.

Error: Table Schema Changed After The Cursor Is Declared
Hi, I have a package which loads data from one sql server table to another. I am loading 15million records in that. Earlier I tested that package with smaller data (less than a million) and it worked fine. So, I put it in production to load that 15 million records. But strangely after loading over 1.5million records, the job aborted with error at destination. The log says 'the table schema has changed after the cursor is declared'. But there is no change made in both destination as well as source. In my package I am using a 'OLEDB Source' to read data from a SQL Server table, using 'Script component' making some changes and loading data to a sql server table using 'OLE DB Destination'. Both source and destination are in same server, but under different schema. Do you have any idea about the problem? Thanks.

I therefore want to pass the variable and the length of the variable into a function to return the correct length.So if location Code = 'AB' this needs to be four characters long so want to pass it into a function and return 'AB 'As I need to do this for 70+ variables is there an easy way to obtain the length of the collation for the variable?regardsTom

Select Declared Variable With Case Statements
I am trying to gather counts for table imports made for files from friday - sunday and create a variable that will be the body of an email. I'd like to use either a case statement or a while statement since the query is the same but the values must be collected for each day (friday, saturday and sunday) and will all be included in the same email. I have declared all variables appropriately but I will leave that section of the code out. Select @ifiledate = iFileDate from tblTelemark where iFileDate = CASE WHEN iFileDate = REPLACE(CONVERT(VARCHAR(10), GETDATE()-3, 101), '/','') THEN Select @countfri1 = Count(*) from tbl1 Select @countfri2 = Count(*) from tbl2 Select @countfri3 = Count(*) from tbl3 Select @countfri4 = Count(*) from tbl4 WHEN iFileDate = REPLACE(CONVERT(VARCHAR(10), GETDATE()-2, 101), '/','') THEN Select @countsat1 = Count(*) from tbl1 Select @countsat2 = Count(*) from tbl2 Select @countsat3 = Count(*) from tbl3 Select @countsat4 = Count(*) from tbl4 WHEN iFileDate = REPLACE(CONVERT(VARCHAR(10), GETDATE()-1, 101), '/','') THEN Select @countsun1 = Count(*) from tbl1 Select @countsun2 = Count(*) from tbl2 Select @countsun3 = Count(*) from tbl3 Select @countsun4 = Count(*) from tbl4 END Is there a way to do what this that works???

Using Declared Variable As Passphrase Slows Query
I have two tables - gift_cards and history - each related by a field called "card_number". This field is encrypted in the history table but not in the gift_cards table. Let's say the passphrase is 'mypassphrase'. The following query takes about 1 second to execute with a fairly large amount of data in both tables: SELECT max([history].[date_of_wash]) AS LastUse FROM gift_cards AS gc LEFT JOIN history ON gc.card_number=CAST(DecryptByPassPhrase('mypassphrase', HISTORY.CARD_NUMBER) AS VARCHAR(50)) GROUP BY gc.card_number When I use a declared variable to contain the passphrase, the same query takes over 40 seconds. For example, declare @vchPassphrase as nvarchar(20) select @vchPassphrase = 'mypassphrase' SELECT max([history].[date_of_wash]) AS LastUse FROM gift_cards AS gc LEFT JOIN history ON gc.card_number=CAST(DecryptByPassPhrase(@vchPassphrase, HISTORY.CARD_NUMBER) AS VARCHAR(50)) GROUP BY gc.card_number This query is part of a stored procedure and, for security reasons, I can't embed the passphrase in it. Can anyone explain the discrepancy between execution times and suggest a way to make the second query execute faster? Thanks, SJonesy

Stored Procedure Using A Declared Variable In Insert Query (inline Or Using EXEC)
Hello, I have a stored procedure where I run an insert statement. I want to knwo if it is possible to do it using a variable for the table name (either in-line or with an EXEC statement without building a string first and executing that string. See examples of what I am talking about in both cases below: I want to be able to do this (with or without the EXEC) : ------------------------------------------------------------------------------------ DECLARE @NewTableNameOut as varchar(100) Set @NewTableNameOut = 'TableToInsertInto' EXEC( Insert Into @NewTableNameOut Select * From tableToSelectFrom ) ------------------------------------------------------------------------------------ I can not do the above because it says I need to declare/set the @NewTableNameOut variable (assuming it is only looking at this for the specific insert statement and not at the variable I set earlier in the stored procedure. I can do it like this by creating a string with the variable built into the string and then executing the string but I want to know if I can do it like I have listed above. ------------------------------------------------------------------------------------ DECLARE @NewTableNameOut as varchar(100) Set @NewTableNameOut = 'TableToInsertInto' EXEC( 'Insert Into ' + @NewTableNameOut + ' ' + 'Select * From tableToSelectFrom' ) ------------------------------------------------------------------------------------ It is not an issue for my simple example above but I have some rather large queries that I am building and I want to run as described above without having to build it into a string. Is this possible at all? If you need more info please let me know.

Update Statement Using Declared Variable Produces Unexpected Results On SQL Server 2005
We are getting unexpected results from the following update statement when it is executed on SQL Server 2005. The strange thing is that we get duplicated values for QM_UID (although when run under SQL Server 2000 we don't get duplicated values) Can anyone explain why this happens or suggest another way of populating this column without using a cursor or adding a temporary autoincrement column and copying the values over? declare @NextID int; set @NextID = 1; update tmp set QM_UID=@NextID, @NextID =

CURSOR Select Clause
I need to dynamically construct the field order of a cursor based on fixed labels from another table, but when I put that resulting query I receive the error: Server: Msg 16924, Level 16, State 1, Line 78 Cursorfetch: The number of variables declared in the INTO list must match that of selected columns. I have 6 fields defined in the cursor select, and 6 parameters in the fetch. The results of running the @sql portion returns valid data. Should this be possible to define a parameter containing the select clause of the cursor? select colnum, coldesc, colname into #ae_defs from ae_adefs select @Sql = (select colname from #ae_defs where coldesc = 'PATIENT NAME') + ', ' + (select colname from #ae_defs where coldesc = 'PATIENT NUMBER') + ', ' + (select colname from #ae_defs where coldesc = 'ACCOUNT NUMBER') + ', ' + (select colname from #ae_defs where coldesc = 'VISIT DATE') + ', ' + (select colname from #ae_defs where coldesc = 'VISIT TYPE') + ', DocID from ae_dtl1' DECLARE myCursor CURSOR FOR Select @SQL OPEN myCursor print @@Cursor_rows FETCH NEXT FROM myCursor into @var1, @var2, @var3, @var4, @var5, @DocID

Order By Clause In DECLARE CURSOR Select Statement Won't Compile
The stored procedure, below, results in this error when I try to compile... Msg 156, Level 15, State 1, Procedure InsertImportedReportData, Line 69 Incorrect syntax near the keyword 'ORDER'. However the select statement itself runs perfectly well as a query, no errors. The T-SQL manual says you can't use the keywords COMPUTE, COMPUTE BY, FOR BROWSE, and INTO in a cursor select statement, but nothing about plain old ORDER BYs. What gives with this?

Cursor/variable Help
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.

Using Cursor Variable As A Tablename
I am currently using a cursor to scroll through sysobjects to extract table names and then extracting relevant column names from syscolumns. I then need to run the following script: declare Detail_Cursor cursor for select @colname, max(len(@colname)) from @table The message I receive is "must declare variable @table". Immediately prior to this script I printed out the result of @table which works fine so the variable obviously is declared and populated. Can anyone let me know what I'm doing wrong or how I can get the same result. Thanks

How To Iterate Through Table Variable Without Using Cursor
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...

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.

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 :)

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
