Losing my margin!?

I am designing a report to output address labels (Avery 5160) and the
spacing of the data in the columns and the rows descrease as the print moves
down the page. By the final row of labels, the name line is in the row
preceeding row. I am using a list object and the margin settings are per
Avery's spec sheet.
Anyone else experience this and have a fix?
Thanks,

with PDF or TIFF. HTML is pretty non-deterministic.

Looping through a recordser in a stored procedure

I have a table [myOrders] with three columns. One of the columns
contains text output data [myText] nvarchar(500), one of them contains
a filename [myFileName] nvarchar(50), one of the columns is a bit to
record if it has been output yet[isOutput] bit default value = 0.

I am creating a SQL Agent job that needs to look at a recordset of
[myOrders] where [isOutput] = 0 and create a seperate text file for
each row using [myFileName] as the filename.

Then I need to mark [isOutput] of each record in [myOrders] as 1.

Ok, so that's the task...

What I'm thinking is I construct a stored procedure that starts with a
select statement:

Create PROCEDURE JustDoIt
AS
set nocount on

SELECT
myText, myFileName
FROM
myOrders
WHERE
(isOutput = 0)

THEN I USE BCP to create the file looping through the recordset above.
THIS IS THE PART I AM CLUELESS ABOUT!

/* NEED TO LOOP HERE */

DECLARE @.ReturnCode int
DECLARE @.ExportCommand varchar(255)
DECLARE @.FileName nvarchar(50)
DECLARE @.FileText nvarchar (500)

SELECT @.FileName = myFileName

/*THIS SYNTAX IS PROBABLY TOTALLY OUTA WHACK:)

SET @.ExportCommand =
'BCP @.FileText queryout "c:\' +
@.FileName +
'" -T -c -S ' + @.@.SERVERNAME
EXEC @.ReturnCode = master..xp_cmdshell @.ExportCommand

/* NEED TO EXIT LOOP HERE */

Then I update all records in [myOrders] to 1

BEGIN TRANSACTION

UPDATE
myOrders
SET isOutput = 1
WHERE
(isOutput = 0)

/* err checking here */

COMMIT TRANSACTION

I'm hoping someone can help me construct this.
Thanks,

I'm glad to see that you are exploring Agent!

Did you ever consider of making it an Active-X job step? You could then
use VBscript for the task, and it may be easier to write files from
VBscript. (Then again, I have never used VB-script myself.) You could
also write a command-line program in whatever language you fancy, and
run the step as as CmdExec.

You could do this in T-SQL, by setting up a cursor, but since you
would have to fork out with xp_cmdshell for BCP for each file, there
may be a performance cost. VBscript (or whatever language) would be
more effective.

The cusror solution is fairly straightforward:

DECLARE your_cur INSENSITIVE CURSOR FOR
> SELECT
> myText, myFileName
, OrderID
> FROM
> myOrders
> WHERE
> (isOutput = 0)

OPEN your_cur

WHILE 1 = 1
BEGIN
FETCH your_cur INTO @.FileText, @.myFileName, @.orderID
IF @.@.fetch_status <> 0
BREAK

> SET @.ExportCommand =
> 'BCP @.FileText queryout "c:\' +
> @.FileName +
> '" -T -c -S ' + @.@.SERVERNAME
> EXEC @.ReturnCode = master..xp_cmdshell @.ExportCommand

IF @.ReturnCode = 0
UPDATE myOrders SET isOutput = 1 WHERE orderID= @.orderID

END

DEALLOCATE your_cur

Now, as it written above, it assumes that @.FileText is a query, but
from your narrative, I believe it is just a file. You could make it
a query by

SELECT @.filetext = 'SELECT ''' + replace(@.filetext, '''', ''') + ''''

Thanks very much for this code. Hopefully I can construct this from
this foundation.
Question though, can I avoid using cursors by taking advantage of BCP
parameters firstrow, lastrow and batchsize parameters so that I output
one row at a time of a variable row recordset? This would be my
first option.
Thanks,
LQ

I want to do this without using a cursor, instead use select top 1 of
the recordset and loop through BCP until there are no more records.

Looks something like

SELECT top1 OrderID, myText, myFileName from tblOrders where isOutput
= 0

>>WHatI need here is to figure out how to extract the value of
myFileName and myText and pass it to the BCP Utility<<

Do until there's no more records in select statement above:

SET @.ExportCommand = 'BCP myText queryout "c:\' + myFileName+ '" -T -c
-S ' + @.@.SERVERNAME
EXEC @.ReturnCode = master..xp_cmdshell @.ExportCommand

UPDATE myOrders SET isOutput = 1 WHERE orderID= @.orderID

Loop

Sorry for being so dumb about this. I have never used this sort of
construction before.

to launch the command shell for BCP on every record, the cost of the
cursor is probably insignificant. But if you insist...

Why Laruen does not want to use a cursor I don't know, but since he
has to iterate anyway, cursor is the best solution for iteration anyway.

Say that you instead do:

> SELECT TOP 1 @.OrderID=OrderID,@.MyText=myText,@.MyFileName=myFile Name
> from tblOrders where isOutput = 0

If there is no index on isOutput (and one would not expect that),
and the table is huge, this can be very expensive. I have no benchmarks,
but I would suggest that for an iteration a cursor is the best way to
go, although it depends on the cursor type. FAST_FORWARD may be the
fastest, but I always use INSENSITIVE.

Anyway, Laruen should not do this in T-SQL at all, he should use VBscript
or similar as I suggested in my previous post. It will be easier to
program and execute faster.

Also, it occurred to me that if tblOrders.myText is the text that is
to be written to the file, the QueryOut thing will not work, since the
newlines in myText causes problem. Then again if the query for queryout is

'SELECT myText FROM tblOrders = ' + str(@.orderid)

that will work.

Lookup with multiple hits

In a Lookup component I've defined a SQL query which returns a sorted resultset. For each Lookup component input row I want to have a single output row. Problem is that for each input row there is possibility of multiple matches in SQL query resultset. From all of the possible multiple hits I want only the first one to be returned, and if no match is found then no output row. How to implement this?

Try changing your lookup query to only return the rows you are interesting in.

Code Block

select

colA
,colB

,max or min (colC)

from

tableA

group by

colA

,colB

|||

The lookup component does this by default does it not?

Edit: that is return only the first result that it runs into. Just make sure that you return the correct row first and you should be fine...

Try the following to prove:

select 19000101 as datekey, '01/01/1900' as datename

UNION

select 19000102 as datekey, '01/02/1900' as datename

UNION

select 19000103 as datekey, '01/03/1900' as datename

UNION

select 19000104 as datekey, '01/04/1900' as datename

UNION

select 19000105 as datekey, '01/05/1900' as datename

in an oledb source

and then in the lookup

select 19000101 as datekey, 'myname11' as name

UNION

select 19000102 as datekey, 'myname21' as name

UNION

select 19000103 as datekey, 'myname31' as name

UNION

select 19000104 as datekey, 'myname41' as name

UNION

select 19000101 as datekey, 'myname12' as name

UNION

select 19000102 as datekey, 'myname22' as name

UNION

select 19000102 as datekey, 'myname23' as name

Notice, there is no match for 19000105, it will redirect.

You will return the values

19000101, '01/01/1900', 'myname11'

19000102, '01/02/1900', 'myname21'

19000103, '01/03/1900', 'myname31'

19000104, '01/04/1900', 'myname41'

Eric Wisdahl wrote:

I believe so. The message about duplicate values is just a warning, not an error. I don't think there's a guaranteed order -- it just picks the first one it comes across.|||

Eric Wisdahl wrote:

Yes. Lookup is a synchronous component; hence the number of rows in the output is the same than the number of rows in the input. If your lookup query returns more than one row for an incoming row; then 'the first' one would be used; and you don't have control over which one would be used.|||SQL query returns result set of multiple contact persons for multiple companies. On output I need for each company to filter out just one of the contact persons. Result set is sorted (ORDER BY) so that if many contact persons are found per comapny one contact person that should be chosen as highest in order. On input of the Lookup component I've put OLE_SRC component which fetches all the companies.

I couldn't use just GROUP BY because I need columns in resultset which aren't used in aggregate function nor should be be group on.
|||

I would not feel comfortable relying in SSIS picking the 1st from the list. If the query in the lookup component is against SQL Server, Oracle or other RDBS where the rank function I would use a query like:

http://rafael-salas.blogspot.com/2007/04/remove-duplicates-using-t-sql-rank.html

Notice that you could mimic the result set even without the rank() function; but the query could get little complex|||Great, thank you all, especially to Rafael.

In an OLE_SRC I manually entered SQL command. I had to do it manually because it seems that Query Builder doesn't (yet) support OVER construct - when I click Build Query on OLE_SRC component it says "The OVER SQL construct or statement is not supported.".
|||

Is your source sql server 2005?

If not, you'll have to use another technique to get the row number

Code Block

select

colA

,(

select count(*)

from tableA b

where b.colA <= a.colA

) as RowNum

from tableA a

|||Yes, the source is SQL Server 2005. OLE DB Source component has Query Builder GUI which doesn't support OVER construct. I entered query manually and it works.

looking for nested XML document as output on a recursive query from sql table

Is it possible to finally have a nested XML document on a recursive query? Let's say that we have a classic parent-child relationship inside a table that is self-refernced. An example of this situation can be found in the Employees table of Northwind DB or in the shining new AdventureWorks DB, HumanResources.Employee table.
In both cases we have somthing like that:

EmployeeID ManagerID Title Firstname LastName

Where ManagerID refers to an existing EmployeeID. I'd like to create and organizational tree.

Using a query like that:

WITH DirectReports (ManagerID, EmployeeID, Title, DeptID, Level, Path)
AS
(
SELECT
ManagerID, EmployeeID, Title, DepartmentID, 0 AS Level, CAST(EmployeeID AS VARCHAR(MAX)) AS Path
FROM
HumanResources.Employee
WHERE
ManagerID IS NULL

UNION ALL

SELECT
e.ManagerID, e.EmployeeID, e.Title, e.DepartmentID, Level + 1, Path + '/'+ CAST(e.EmployeeID AS VARCHAR(MAX))
FROM
HumanResources.Employee AS e
JOIN
DirectReports AS d
ON
e.ManagerID = d.EmployeeID
)
SELECT *
FROM DirectReports
ORDER BY Path

The query is a sample one present in the BOL and modified a little. I also remeber the I've see something similar to a document present at the MSDN site.

Now i'd like to have this result in XML, with the correct nesting:

but without the need to use SQLXML (as I did to obtain the result above).
I've made some attempts, but seems impossible! :-(

Using FOR XML clause will produce a similar xml document but with no nesting, will I was expecting it since a simple FOR XML on a simple JOIN does create them.

It works using UDF but UDF has limit like maximum of 32 recursively nested function invocations. So it will not work for unlimited depth.

Feedback appreciated :-)

vshah:

I am really just starting to learn XML and so I am not sure that I understand your question correctly. Here is some code that seems to produce the output you have requested. Would you please give this a look and tell me if this is headed in the right direction?

Kent,

Isn't there a way to simplify that solution?

The actual code lenght?

looking for nested XML document as output on a recursive query from sql table

EmployeeID ManagerID Title Firstname LastName

Where ManagerID refers to an existing EmployeeID. I'd like to create and organizational tree.

Using a query like that:

UNION ALL

The query is a sample one present in the BOL and modified a little. I also remeber the I've see something similar to a document present at the MSDN site.

Now i'd like to have this result in XML, with the correct nesting:

but without the need to use SQLXML (as I did to obtain the result above).
I've made some attempts, but seems impossible! :-(

Using FOR XML clause will produce a similar xml document but with no nesting, will I was expecting it since a simple FOR XML on a simple JOIN does create them.

It works using UDF but UDF has limit like maximum of 32 recursively nested function invocations. So it will not work for unlimited depth.

Feedback appreciated :-)
