Set-based INSERTS Rather Than A Loop
Jan 20, 2006I have a table with a series of rows for period 1 - these always exist
drop table tblmain
create table tblmain (period int, rfreq int, pfreq int)
insert tblmain (period , rfreq , pfreq )
select 1 , 1 , 1
union all
select 1 , 1 , 3
union all
select 1 , 1 , 6
union all
select 1 , 3 , 3
union all
select 1 , 3 , 6
union all
select 1 , 6 , 6
union all
select 1 , 6 , 12
select * from tblmain
period rfreq pfreq
1 1 1
1 1 3
1 1 6
1 3 3
1 3 6
1 6 6
1 6 12
*/
I need to do a whole lot of inserts with incremented period values up to and including
a number assigned in a different table, FMaxes based on JOINing the two tables on the rfreq column
CREATE TABLE FMaxes (RFreq INT , MaxFINT)
insert FMaxes (RFreq , MaxF)
select 1 , 5
union all
select 3 , 3
union all
select 6 , 2
select * from FMaxes
RFreq MaxF
1 5
3 3
6 2
Ive been scratching my head for hours trying to figure out a set-based approach rather than a loop
solution which I could produce
The desired result would be inserts from period 2 onwards - result set below
select * from tblmain
period rfreq pfreq
1 1 1
1 1 3
1 1 6
1 3 3
1 3 6
1 6 6
1 6 12
2 1 1
2 1 3
2 1 6
2 3 3
2 3 6
2 6 6
2 6 12
-- no period 3 or higher for rfreq value 6 because table FMaxes holds an MaxF value of 2 etc
3 1 1
3 1 3
3 1 6
3 3 3
3 3 6
-- no period 4 or higher for rfreq value 3 because table FMaxes holds an MaxF value of 3 etc
4 1 1
4 1 3
4 1 6
5 1 1
5 1 3
5 1 6
Thanks in advance
Using For Each Loop Container To Pass Parameters To Command Utility
Sep 1, 2006Hello
I want to use a for each loop container to go through all files listed in a particular folder.
Each of those file names must be passed as a parameter to the relog.exe command utility
example:
Folder C: emp
Files in C: emp: log1.csv, log2.blg, log3.txt
The following lines must be executed:
c:
elog.exe c: emplog1.csv -f SQL -o "SQL:PerfCounters!PerfCounters"
c:
elog.exe c: emplog2.blg -f SQL -o "SQL:PerfCounters!PerfCounters"
c:
elog.exe c: emplog3.txt -f SQL -o "SQL:PerfCounters!PerfCounters"
The relog utility converts the performance counter logs to sql format and pumps it in the database (DSN:PerfCounters)
The idea is that someone drops multiple counter logs in c: emp and you start a SSIS package to pump the data from all the files in the database.
I'm not sure where to start. Do I have to put a Script task inside the For Each loop container en start scripting the commands in Visual Basic.Net or is there a more simpler way to achieve this in SSIS?
Many thanks!

FOR EACH Loop To Export Files Based On Header Record
Dec 21, 2006Hey guys,,
Well im new at this SSIS stuff and i have something that i am trying to do, but cannot get it to work.. Ill try to explain, and if anyone can help me or point me in the right direction it would be much appriciated..
I have 2 tables, one header table. and one lines table. This is a one - to -many relationship.. ie 1 header, many lines.. This is a Order Header, and Order Lines table setup.. Order header has Order numbers and and email address field that link to the lines table by order number. I also have a view which links all this info together.
I would like to export a excel file (preferable named from the order number column - but that can come later) for each order number in the header table. The excel file will contain the details from the View that was created. I want this to loop through all the header records in the header table and create a excel file for each one..
Down the track i want to add a send mail task to this and pass the email address to a variable so i can use it in the send mail task.. But ill get the main part working first..
Anyhelp would be more than helpful.. I tried to set this up, but i am stuck on the enumerator part..
thanks again, scotty
Loop Through Flat Files Based On A Date Range
Feb 9, 2007Hello,
I currently have a For Each File container that loops through all files from a specific directory. The files have a naming convention that looks like this;
CDNSC.CDNSC.SC00015.01012007
The last segment of the file name is the date of the data in the file (mmddyyyy). The create date for these files is always a day later than indicated in the file name.
What I would like to do is to have more control over the 'range' of files that are looped through by using the date portion of the file name to define what group of files should be looped through. Ideally, I would like to have a 'StartDate' variable and an 'EndDate' variable that I could define at run time for the package, and the package would loop through all of the files where the date portion of the file name fell between 'StartDate' and 'EndDate'.
Any ideas on this?
Thank you for your help!

An Access OnFormat Procedure Would Be Replaced In SQL Reporting Services By What?
Mar 27, 2007In the field, the operators are presented with 5 categories, each category having between 3 and 5 possible selections, for example:
Weather - clear(1), cloudy(2), rain(4) or snow(8).
If the operator selected cloudy and rain, the value of Weather would be 6.
I want to print a report in the office that will list the categories and the available selections for each, putting an "X" next to those selections that were checked by the operators.
In Access, it was easy - I plugged a decode procedure into the OnFormat event...
cnum = obj![WEATHR]
If cnum - 8 >= 0 Then
obj![SNOW] = "X"
cnum = cnum - 8
End If
If cnum - 4 >= 0 Then
obj![RAIN] = "X"
cnum = cnum - 4
End If
If cnum - 2 >= 0 Then
obj![CLOUDY] = "X"
cnum = cnum - 2
End If
If cnum - 1 >= 0 Then
obj![CLEAR] = "X"
End If
Making the change to SQL Reporting Services, I'm clueless...as you can tell, I'm not even sure how to ask the question.
Any help would be greatly appreciated.
SQL Select Command With Where Clause Variable Based On ASP.NET TextBox

May 14, 2007I have a dataflow task. On which I have OLEDB as my source. I connect to my database and execute a stored proc. the stored proc results in a result set with only one row and two columns. First Column is an integer and the second row is a varchar(max) with xml script in it. Not that it should matter because it is in varchar(max).
Anyway, it give me an error

Can I not have a stroed proc that returns a result set as my data source?

SQL Cache Dependency Invalidation - Can It Work On The Procedure Based Command?
Dec 19, 2005I was wondering if SQL Cache Dependency would be in fact invalidated if:
1. it was created based on a procedure type command.
2. if the select statement retrieves the data from multiple database tables
Any help would be more appreciated. I am stuck with the fact that none of the data bases on sql dependency is invalidated. I spent literally hours to understand what i am doing incorrectly.
Thanks

View 1 Replies View RelatedQuestions About Memory Based Bulk Copy Operation(InsertRow Count,array Insert Directly,set Memory Based Bulk Copy Option)
Feb 15, 2007Hi~, I have 3 questions about memory based bulk copy.
1. What is the limitation count of IRowsetFastLoad::InsertRow() method before IRowsetFastLoad::Commit(true)?
For example, how much insert row at below sample?(the max value of nCount)
for(i=0 ; i<nCount ; i++)
{
pIFastLoad->InsertRow(hAccessor, (void*)(&BulkData));
}
2. In above code sample, isn't there method of inserting prepared array at once directly(BulkData array, not for loop)
3. In OLE DB memory based bulk copy, what is the equivalent of below's T-SQL bulk copy option ?
BULK INSERT database_name.schema_name.table_name FROM 'data_file' WITH (ROWS_PER_BATCH = rows_per_batch, TABLOCK);
-------------------------------------------------------
My solution is like this. Is it correct?
// CoCreateInstance(...);
// Data source
// Create session
m_TableID.uName.pwszName = m_wszTableName;
m_TableID.eKind = DBKIND_NAME;
DBPROP rgProps[1];
DBPROPSET PropSet[1];
rgProps[0].dwOptions = DBPROPOPTIONS_REQUIRED;
rgProps[0].colid = DB_NULLID;
rgProps[0].vValue.vt = VT_BSTR;
rgProps[0].dwPropertyID = SSPROP_FASTLOADOPTIONS;
rgProps[0].vValue.bstrVal = L"ROWS_PER_BATCH = 10000,TABLOCK";
PropSet[0].rgProperties = rgProps;
PropSet[0].cProperties = 1;
PropSet[0].guidPropertySet = DBPROPSET_SQLSERVERROWSET;
if(m_pIOpenRowset)
{
if(FAILED(m_pIOpenRowset->OpenRowset(NULL,&m_TableID,NULL,IID_IRowsetFastLoad,1,PropSet,(LPUNKNOWN*)&m_pIRowsetFastLoad)))
{
return FALSE;
}

Column Based On Other Column (short Name Based On Name), When To Do The Transformation?
Oct 18, 2007Hi!
I am designing a dimension table which will include a short name column based on the (full) name column. For example say Product dimension where I will have ProductName and ProductShortName. ProductShortName will be the first 6 characters of ProductName. I could populate ProductShortName using:
Substring in the select when I select from the original system, e.g. SUBSTR(PRODUCT_NAME, 1, 6) AS ProductShortName
Create a derived column in the SSIS flow which does the same thing
Create the ProductShortName column as a computed column which uses substring on ProductName
Create a trigger that populates ProductShortName based on ProductName when a row is inserted or updated
Create a named calculation in the table in the Analysis Services project's data source view
Create a named query in the Analysis Services project's data source view
I usually use 1, and 5 or 6 would only be used if I only will create reports against the cubes. 3 seems easiest to maintain, so I am thinking about using that one, but maybe it is slow for the data flow as I imagine it must be something like using 4, or when is the column "created" at runtime, i.e. when the table is queried?
Which approach(es) do or would you use? Pros and cons?
Thanks!
How Do You LOOP In T-SQL?
Aug 20, 2007I used to loop through recordsets with ease in old classic .asp pages.
Please Help me understand how Professionals now loop through and update tables using JUST SQL Query Analyzer using my pseudo-code provided below.
I would love to learn how to do it to better develop my skills.
SELECT * FROM zz_2007_Booth_Visitors
WHERE COALESCE ([Product Interest - Other Actuator],
[Product Interest - Chillers],
[Product Interest - Other Chiller],
[Product Interest - Electronic Products],
[Product Interest - Other network interfaces],
[Product Interest - Fittings],
[Product Interest - High Vacuum],
[Product Interest - Other high vacuum actuators],
[Product Interest - Pick& Place and Transfer],
[Product Interest - Teflon Products],
[Product Interest - Training],
[Product Interest - Valves& Manifolds],
[Product Interest - Actuators]) Is Not Null
Order BY [Contact Name]
IF [Product Interest - Actuators] IS NOT NULL THEN
UPDATE Booth_Visitors_Data Set Act_Phuematic = 1 Where [Contact Name] = [Contact Name]
IF [Product Interest - Other Actuator] IS NOT NULL THEN
UPDATE Booth_Visitors_Data Set Act_Electric = 1 Where [Contact Name] = [Contact Name]
IF [Product Interest - Other Chillers] IS NOT NULL THEN
UPDATE Booth_Visitors_Data Set Chiller = 1 Where [Contact Name] = [Contact Name]

While Loop
Mar 3, 2008Hello everyone,I've got this While loop here which is giving me a problem:WHILE (SELECT ProductId FROM _ShoppingCart WHERE CartId = @CartId) IS NOT NULLBEGIN DECLARE @ProdId int, @ProdSize varchar, @ProdQuan int SELECT @ProdId = ProductId, @ProdSize = ProductSize, @ProdQuan = Quantity FROM _ShoppingCart WHERE CartId = @CartId If @ProdSize = 'XL' BEGIN UPDATE _ProductBatches SET XL = '0' WHERE ProductId = @ProdId END DELETE FROM _ShoppingCart WHERE ProductId = @ProdId AND CartId = @CartIdEND The problem is that the IF statement isn't being executed. And I know for a fact that 'XL' is ProductSize in my _ShoppingCart database. Whats even stranger is that my delete statement is being executed. So @ProdId is Being set correctly, but when it gets to the IF @ProdSize = 'XL' it doesn't get executed for some reason. If @ProdId is being recognized correctly in my DELETE statement, why is my @ProdSize not being reconized correctly in my IF statement. I checked my _ShoppingCart database, and my ProductSize is definitely 'XL'. Can any one see what could be going on here. Thank you, Alec

Mar 4, 2008Hello everyone...... I'm trying to do the following but am having issues:WHILE (SELECT ProductId FROM _ShoppingCart WHERE CartId = @CartId) IS NOT NULLBEGIN execute code with item......... erase itemEND In the while loop I want to execute code from each item in my _ShoppingCart and then erase them until there are no more items. However the above code gives me the error: "Subquery returned more than 1 value. This is not permitted........" It works fine when there is only one item. Does any one know what format to use when dealing with more that one entry? Thank you, Alec

Sep 21, 2000hi,
I am trying to find a way of using a loop that won't be an endless loop because I have to insert parts of a string until the string reaches the end. I am unable to make the loop get to a point where the statement is false.
Is there anyway I can find out the length of the string so that I can tell the statement to loop while the statement is true?
