Will using continue cause an infinite loop in a cursor or will the cursor know to go to the next record?

In MSDN file I read about static cursor
STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that
Static Cursor
declare ll cursor global static
           for select name, salary from ag
 open ll
            fetch from ll
Â
             while @@FETCH_STATUS=0
              fetch from ll
               update ag set salary=200 where 1=1
Â
  close ll
deallocate ll
In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says modifications is not allowed in the static cursor.But I am able to update the data using static cursor.
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

How can I cause my insert statement to skip over (without failing) rowswhere there's a primary key constraint violation?I've got a case where daily I insert >500k rows of daily data, wherethe data is date and time stamped. So, for example, I have an insertstatement with constraint: WHERE date >= '5/20/05' AND date <'5/21/05'. That takes care of one day's data (5/20).However, the next day's data (5/21) will still have some time stampsfrom the previous day. Therefore the statement needs to be somethinglike WHERE date >= '5/20/05' AND date <= '5/21/05'. The 5/20 data isalready loaded but I need to take the 5/21 data which just happens tocontain just a few rows of data marked 5/20 and insert it withoutgenerating a primary key error from all the other 5/20 rows that arealready inserted.-Dave

I have transactional Replication from A to B.
My distribution agent failed becos of a primary key violation error in a table.[i have not included the skip error option].
Then the replication stopped.

Imagine this SQL statement:
Code SnippetINSERT INTO B SELECT * FROM A
If one of the insert fails ... don't continue, the statement fail. For example if any field in A violate a constraint in B, the statement fails.
I want that the statement continue if errors occurs, if i lost a number of rows don't matter ... but if i can save or log this row will be great too !!
Is posible? Any way to do it?

We have a package that loads the data from several excel files into database in a forloop.
Everything works files until the package hits the bad file.
My goal is to continue the loop to process the rest of the files by skipping the bad file and error. In each task OnError I am creating custom error message to send an error/ sucess summary email out at end of the process.
How can force the for loop to continue when there is an error?
Is there any way to reset the errors?
Thanks

Do you have to set the Error Output on DF components to "Fail Component" in order to get the errors?
What I would LIKE to do is a combination of "Ignore Failure" and "Fail Component". You see, I am using the Logging feature in my package that creates the sysdtslog90 table in the SQL database. The errors that I am logging make sense and have enough information for my purposes.
The problem is that I would like to continue processing the data and not have it stop when a data error occurs. I REALLY do not want to Redirect Rows unless it is necessary for me to do what I am asking.
Using Ignore Failure on both the source text file and destination SQL table allows the "good" data to be inserted, but I cannot get any info on the columns in error. Conversely, if I choose to Fail component, I get the info on the columns in error, but only the data that was inserted before the error was encountered is inserted into the table.
Suggestions?
With a ForEach container, configured to loop through files in a
directory, if I have a problem with a file.. can I direct the loop to
skip on to the next file?
I'm processing structured files, first record of each is some
header info, body records are in the middle, and then the last record
is a trailer containg a checksum
So, for each file in the directory, I split the records into three raw
files, one for header rec(s) , one for body recs and one for trailer
recs. (based on line numbers and using a conditional split to direct
the records)
Then I start by processing the header recs in a dataflow.. if all goes
well there I move on to the next dataflow to process the body recs from
the DataRecs raw file.. etc...
I would like to do some validation at each processing step.. if a
header rec fails validation say... then I'd like to just stop
processing that file and move onto the next file...
Now, I don't see my validation throwing an exception... so its more
that I'd decide (maybe using an Audit ) that the header doesn't pass
validation.. then I'd like to put a record in an error table (with info
about filename, source etc, not just content of the current data row)
But not sure what approach to take on this...
If there is an appropriate section in BOL please point me at it...
Thanks

Hi guys,
I have some triggers that insert data in a table located in a remote server. If the remote server happens to be down I want to continue with the original transaction anyway. Can I use a BENGIN TRY BEGIN CATCH block to continue with the transaction in the trigger and also insert the data into a temporal local table if the remote insert fails?

Hello,
In my SSIS package I am trying to import a .csv flat file with about 170,000 rows of data with 75 columns (I know this is rather large). I would like to create a SSIS package that loads ALL of the rows of data into a table. This table has it's fields defined (such as money, float, varchar, datetime, etc). I want the data to load to this table even if there is a conversion error converting any field. When the data is loaded to this table, any fields that couldn't be converted should be set to null. Of the 75 columns of data, there are MANY columns that could be invalid.
For example, if the flat file contains the value "00/00/00" for my "PaidDate" field, I would want all of the other fields to be populated and the value for this particular record's "PaidDate" field to be null.
It would also be nice if I could trap any of the fields that caused a problem and log them along with the row.
I know that SSIS supports the "Redirect Row" method for handling data, but in my case, I don't want to redirect it. I want to continue to load it, just with a null value.
Is there an easy way of doing this (i.e. perhaps by using the Advanced Editor for the Flat File Source and setting something in the Input/Output columns)? I really don't want to create a Derived Column or Data Conversion transformation for every field that needs to be converted (b/c there are 75 columns to maintain this for).
I know if I import this file to an Access 2003 database, it imports the data fine and logs any conversion errors to an "_ConversionErrors" table. I am basically looking for this same behavior in SSIS, without having to maintain 75 columns.
TIA
How can we continue with the rest of the iterations in ForEach Loop after handle an error.
I Have a dataflow task inside a for-each loop and processing a set of flat files in that. When error occurs in the dataflow task, i moved that particular flat file to another location. But, If an error occurs at first falt file, It moves that flat file to the location i specified and not continue with the next file (The Execution finished at that stage itself afetr the first flat file).
I Set the FailParentonFailue of Dataflow task to TRUE (Since its inside the for loop).
Any thing i have to change ? Or Where i miss the thing.
Hi,
How can avoid SQL to rollback the transaction after an insert fails?. I would like to keep the sucessfully inserted rows and continue with next ones after a single one has failed, and then report the ones that failed.

Hi,
On the last Sunday 26/12/04 on 20:00 I got on one of our applications in the customer site this error:
"There is insufficient system memory to run this query."
Details:
Computer: IBM XSERIES_345, dual CPU 2.8 Intel xeo, 1,047,952 KB ram, windows 2000 server sp4.
Disk space: 4395 MB, Virtual memory: initial size 1536 MB, Max size 3072 MB. Registry size: current 14 MB, Max 90 MB.
SQL Server 2000 SP 3, two production databases (1) Data size 100 MB, log size 15 MB (2) Data size 500 MB, log size 125 MB
All the memory options are configured as default i.e. dynamically configure for memory and not changes in any sp_configure options.
SQL server is the only major application running on the machine.
Facts:
On that evening the I've checked the Task Manager and found that SQL Server use 500 MB in Mem Usage and 1200 MB in VM size.
In the query analyzer I execute the select query which results the "…insufficient system memory…" error on both databases and on the one with more data it failed with this error, but on the other database it completed successfully.
I restart SQL Server service to solve it, and as for today 28/12/04 at 08:00 it use 590 MB in Mem Usage and 590 MB in VM size.
I have checked the system with Performance monitor and didn't find any problems I use the Memory: Pages/sec, Memory: Available Bytes, Physical Disk: % Disk Time, Processor: % Processor Time, SQL Server Buffer: Buffer Cache Hit Ratio.
We have 8 user connections for one of the database and 16 for the other one.
Our system runs with this configuration for 2 months, I backup the databases FULL, DIFF and LOG backup.
It's not real time system, and the load on the SQL is medium, but we use bad queries as update for all fields in one query (please don't ask…)
I know that SQL server is greedy with the memory and released memory only if other process needs it.
Any ideas why it happens?
Thanks,
Yaniv

Hi
I have a CSV file which sometimes contains the odd CSV error, for this reason the odd row throws an error.
If I have a clean CSV file my SSIS package works great, but I am having problems getting the package to continue past the rows in the file that throw errors.
How do I :
Get the package to continue on error, I have tried playing with the Propagate Variable with no joy
Add an Error event, which will capture the error and log it to a SQL table or File Destination?
Any help will be great!

I have an SSIS package where I have directed the error output to a Flat File Destination. The issue is that there are some bad entried in a set of log files, where the source file reads on more delimited column than there are actual columns. (As in there are 26 column headers, and one row will have 27 commas, or delimiters.) I am trying to redirect the row output to put the bad rows into a Flat File for debugging purposes. Although, the package is not able to continue past the error. As soon as it hits the bad row, it fails despite the error output.
Any ideas?
