Using A &"dynamic Top&" Statement With A Cursor

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

Dynamic SQL In Cursor
I need to pass a list of values into a cursor as such...


DECLARE
@group_SQL varchar(255)

SET @group_SQL = 'SELECT group_id FROM groups where group_id in (' + @group_id + ')'

DECLARE groupContact_import_cursor CURSOR
FOR EXEC(@group_SQL)
OPEN groupContact_import_cursor
FETCH NEXT FROM groupContact_import_cursor INTO @group_id
WHILE (@@FETCH_STATUS = 0)
BEGIN
insert into groupContacts (group_id, contact_id) values (@group_id, @new_cid)
FETCH NEXT FROM groupContact_import_cursor INTO @group_id
END
CLOSE groupContact_import_cursor
DEALLOCATE groupContact_import_cursor

But MS SQL doesn't seem to like the FOR EXEC(@group_SQL). Can someone shed some light?

TIA

Dynamic Cursor
I am trying to use a dynamic cursor in a stored procedure:
The code looks like this :


/************************************************** ***
set @sFormula = 'Monthlyformula'
set @sStartDate = '02/01/2004'
set @sEndDate = '02/01/2004'


exec('DECLARE APPGRIDROWS_METRICS CURSOR FOR select populateid From appgridrows where histdisplaygrid = 3 And '+ @sFormula +' Is Null and exists (SELECT 1 From PAYROLL_DATA_PERIOD as h Where h.id=1 and h.populateid=appgridrows.populateid and h.StartDate between '+ @sStartDate +' and '+ @sEndDate +')' )
/************************************************** ***

And this is what it is interpreting

select populateid From appgridrows where histdisplaygrid = 3 And Monthlyformula Is Null and exists (SELECT 1 From PAYROLL_DATA_PERIOD as h Where h.id=1 and h.populateid=appgridrows.populateid and h.StartDate between 02/01/2004 and 02/01/2004)

My problem is Is there anyway that I can put the quotes before those dates('02/01/2004') so that my cursor has some records returned

Thanks in advance

Declare Cursor With Dynamic SQL?
Hello..

Can you declare a cursor with dynamic SQL?

I have a situation where the SQL for my cursor MUST be assembled in a buffer, but I cannot get the cursor declaration to accept my buffer as the SQL statement.

these attempts did not work:

DECLARE crsCursor CURSOR FOR @vchrSQL
DECLARE crsCursor CURSOR FOR (@vchrSQL)

Does anybody know if you definitely can or definitely cannot use dynamic SQL with cursors?

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

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

Need Help With A SQL Statement - Trying Not To Use A Cursor
I'm just know basic SQL but not enough to write any complex queries.The problem I'm facing right now keeps me thinking to use a Cursor butI've seen a lot of posts on here saying Cursors are bad so I'm hopingthere is a complex query that can give me the data I need.I have about 6 pages in website where I need to display a datagrid ofinformation. There should be 5 columns, Filename, and then 4 CategoryTitles (These category titles are stored in a table calledPageCategory). I have another table, XREF_Doc_Page that stores thePageID, DocID (ID to know what file it is), and PageCategoryID. So Ican query this table with a pageID to see all the results that shouldbe on this page but I don't know how to format it the way I need mydatagrid?In order to have the records from PageCategory be columns, is this acrosstab query or something?My only thoughts right now are to user a cursor to query Pagecategoryand build a temp table somehow with these as the columns?? (Not surehow'd that would work yet).So the datagrid would have the 5 columns like I said and then justlist all files associated with this page and put a checkmark underwhichever category it was assigned to (example below...)Files PageCat1 PageCat2PageCat3 PageCat4abc.pdf Xxyz.pdf Xjkl.pdfx

Using Select Statement Instead Of Cursor
Hi All, Can anyone please help?

TableA has data as below:

ssn sex dob rel_code
111111111 m 19500403 m
111111111 f 19570908 w
111111111 f 19770804 d
111111111 f 19801203 d
111111111 f 19869712 d
111111111 m 19870907 s
111111111 m 19901211 s

I have to convert the rel_code into a specific manner so the data will look as below in TableB:

ssn sex dob rel_code
111111111 m 19500403 01
111111111 f 19570908 02
111111111 f 19770804 20
111111111 f 19801203 21 111111111 f 19869712 22
111111111 m 19870907 30
111111111 m 19901211 31

Member's rel_code = 01
spouse's rel_code = 02
daughter's rel_code starts from 20 with the oldest and increments by 1.
Son's rel_code starts from 30 and increments by 1 from oldest to the youngest.

I know You can write a Sp with cursor and do this, but I would like to know if you can accomplish the same thing by a select or case or something else instead of a cursor.

Thanks in advance.

Select Statement In Cursor
Hi...


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.

Please help!!!

Thanks much indeed

Help With Cursor And Fetch Statement
Hello,
 
I am hoping someone can help me with using the cursor and fetch functions. I have not used these features in the past and I am now stuck when trying to use IF statements with the fetch function.

I have a temp table populated with the below headers and their associated data.

The headers are as follows:
ItemRcvdKey, TranID, TranDate, QtyReceived, UnitCost, ItemKey, WhseKey, ItemID, ShortDesc, WhseID, QtyOnHand, StdCost.

The information contained in this temp table lists every single receipt of goods against all of our inventoried items. The QtyOnHand listed on each record is the total QtyOnHand for that item in that warehouse. What I need the fetch to do is grab the receipt of goods records, starting with the most recent TranDate, and pull them into the new temp table until the QtyOnHand is reached. The QtyonHand it should be comparing too is the one listed on the first fetched record. Once the Sum of the QtyRcvd is equal to or is greater than the QtyOnHand for that item I need the fetch to move on to the next item number and perform the same function.
 
One thing I need to be clear on is that if there are 3 Receipt Records(TranID) for Item A in Warehouse A, the total QtyOnHand will be listed 3 times. I need to make sure that the Fetch is comparing all the records for Item A in Warehouse A to one instance of the QtyOnHand.

The other aspect is that there will be receipt of goods for the same item in multiple warehouses. So I also need the Fetch to be sure that when it is grabbing records and putting them in the temp table, it makes sure it is matching the ItemID and the WhseID with the record it started with.

The current script I have written is below. If you can offer any help I would greatly appreciate it.

 



Code SnippetDeclare @ItemID VarChar(30),
        @QtyOnHand Decimal (16,8),
        @WhseID VarChar (6),
        @SumRcvd Int,
        @TranID VarChar(30),

        @UnitCost Decimal (16,8),

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.

Any help is greatly appreciated

Thanks!

24000 Invalid Cursor State. Prepared Statement
I have written a routine to search a unique record using prepared statement. Its my first sql coding with c++.

I am not using / importing any dlls.

I connect+allocs handels , then use SQLPrepare(StmtHandle, SQLStmt,SQL_NTS); to generate a guery.

I have written bind parameters and sqlexecute +sqlFetch in a loop and loop gets executed till ESC key is pressed.

First time when I bind paramaters using SQLBindParameter it works perfect.

When loop gets executed secondtime onwards, it gives an error.
SQLState: 24000 [ODBC Client Interface]Invalid cursor state.

If I open connection, handles, and prepared starement in same loop, THEN it gives correct record without 24000 error.

I want the advantage of prepared staement. So I do not want to close and open connection and prepare statement every time.

Have I missed any step?
Where & when I should code the cursor type? Any specific libraries I need to link?

Thanks

Moving Average Using Select Statement Or Cursor Based?
ID DATE(dd/mm/yy) TYPE               QTYIN  COST_IN_AMT        COST_OUT_AMT(MOVING AVERAGE)   
1          01/01/2007  PURCHASE            10                1000
2          01/01/2007  PURCHAES              5                1100
3          01/01/2007  SALES                    -5                                     *TobeCalculated

7         01/01/2007   Purchase                20                12000
 
I have a table when user add new sales or puchase will be added to this table ITEM_TXNS. 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
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

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?

Thanks in advance

Stored Procedure With CURSOR OUTPUT Parameter, Using JDBC And A Callable Statement
My server is MS Sql Server 2005.  I'm using com.microsoft.sqlserver.jdbc.SQLServerDriver as the driver class.  I've established a connection to the database.

I'm trying to invoke a stored procedure using JDBC and a callable statement.  The stored procedure has a parameter @CurOut CURSOR VARYING OUTPUT.  How do I setup the callable statement so the output parameter is accepted by the driver?

I'm not really trying to pass a cursor up to the database Server but I'm wanting a cursor back from the stored procedure that is other than the result set or other value the stored procedure returns.

First problem: What java.sql.Types (or SQL Server specific) value do I specify for the out parameter I'm registering on the CallableStatement?

Second problem: What do I set the value of the parameter to?

The code looks like:

CallableStatement cstmt = myConnection.prepareCall(sQuery);

cstmt.registerOutParameter(1, Types.OTHER); // What is the right type?

cstmt.setNull(1, Types.OTHER); // What is the right type?

if (cstmt.execute()) {

 ResultSet rs = cstmt.getResultSet();

}

Execution results in a NullPointerException from the driver.

What am I doing wrong?

Thanks for your assistance.

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...

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?

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.

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
