Has anyone seen precedence constraints disappear in a package after closing and opening again? In this case, it's not package-wide. Only constraints inside one Foreach Loop container disappeared. Any idea what causes this to happen?
p.s: Yes, I did Save All. Most of these contraints were saved in the package for more than a week anyway.
Hello,
I've recently begun exploring Integration Services and have a question regarding a Control Flow element.
I'm trying to understand precedence constraints. Specificially, the logical AND and logic OR components. If I have two constaints A and B where A is using a logical AND and B is using a logical OR, how are the constraints evaluated? The Evaluation Operation is set to "Expression and Constraint" for both constraints.
If my understanding is correct, path A would be followed if both A AND B are true. Path B would be followed if A OR B is true. Is this correct?

Hello,
I have a package that executes 2 sql tasks then another SSIS package. My precedence constraints between sql task 1 and sql task 2, and sql task 2 and the SSIS package check that @ErrorValue == 0.
@ErrorValue is set after each sql task (both of which execute stored procs) with the value of the output parameter for the stored proc. I have run both stored procs on the server and both return 0 in the output parameter.
When I run the package the two sql tasks execute as expected (tasks turn green indicating success) but the package stops at that point and the SSIS package task never executes.
If I remove the second sql task and connect the first sql task to the package task with the @ErrorValue == 0 precendence constraint the package task still does not execute (even though the constraint worked to get the sql task 2 to execute).
The package only runs if I remove the expression in the second precedence constraint (between sql task 2 and the package) thus changing it to simply 'on success'.
Please help!
Is it possible to use objects in precedence constraints? For example, I have a collection object that may or may not be populated in a script at some point and want to be able to execute different paths depending upon whether the Count property equals zero or not.
I realize I could very easily just create another int variable and populate it accordingly, but I am just curious about this. I couldn't get it to work, but then I am really just starting out here and just not sure if I am doing it wrong.
Thanks!

I have about 12 sequence containers mapped out to execute separately based on a precedence contraint and an expression. These lie at the same level and order in my sequence. Only one of these will execute based on an expression. After any of these executes, I have a consecutive sequence container that I'm attempting to execute. I've set the precedence contraint from all twelve of the prior sequence containers to this single sequence container that I would like to run after any of the 12. My problem is that the package will only allow one of these twelve sequence containers to become a precedence of this second single sequence container at a time. The package will let me graphically attach the precedence constraint from all 12 to this single sequence container, but when the package runs, it fails to follow through to this single sequence container. I'm trying to figure out why this is the case and how I can get what I would like to work -- work. Thanks.
View 3 Replies View RelatedI have three control flow tasks that are executing in consecutive order. Tasks 1 and 3 will always execute, but sometimes (based on an expression) task 2 will not. I would like to use precedence constraints in such a way that task 3 will execute regardless of whether task 2 executes, but in the event task 2 does execute, task 3 will only execute AFTER task 2 completes. Is there a way to accomplish this without setting the disabled property of task 2 at runtime?

I have created a task that uses a ForEachFile Loop. Within that loop I load 5 files. Once those 5 files have loaded successfully I want to run a stored procedure. I placed this stored procedure into a script task. The script task has 5 precedence constraints,. They are a success on the load of the files. When I run the task, the 5 files load, but the script task will not start. I have gone so far as to check each load individually to see if it would start the script task, which they do. It's only when I add more than 1 precedence constraint that the script task will not run. The precedence constraints are set to AND, so they all are required. They all succeed. What am I doing wrong?
View 3 Replies View RelatedHey everyone,
I have used the set values option of the execute package utility many times to change values on variables in the package with no problem before, however have run into a stumbling block when coupling this with precedence constraints. I have a package that goes down a different path based on a precedence constraint that works perfectly if the default value of a variable is used....however when I pass in a new value via Set Values in the execute package utility the package will error out with this:
The expression "@[User::IVR_FLAG] == 1" must evaluate to True or False. Change the expression to evaluate to a Boolean value.
IVR_FLAG is an int with a default value of 1, and if left that way(or changing it to another value in the package, as long as the default is used) this error will not occur....it will go down the proper path. But when Set Values is used to run the package to change IVR_FLAG, the above error occurs, which doesn't make sense since the above expression should still evaluate to either true or false. Anyone have any thoughts or suggetions?
Thanks,
Adrian
I had a Send email task linked to my Sequence Containers in my package and it was working fine. Everytime the container fails it would send an email to myself.
At some point all Failure constraints stopped working. Failure constraints work if I add brand new tasks, but with the existing tasks, they don't work. The Task which fails, turns red and execution stops. Next failure task is not executed.
I am not sure what triggered it to stop working. I cannot get anything on the log
Any help is appreciated.
This is more a medium level annoyance than a problem. When I save a package, close it and later re-open it, the precendence constraints end up all over the place making my neatly layed out diagram a shambles.
Call me anally retentive if you like (you wont be the first ), but I find this extremely annoying. Does anybody else have this problem? Does anyone have a solution?
I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this?
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Hi,
I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error.
e.g
MOB 401.908.804 - Fails
0401.907.324 - okay
8239 9082 (pager) - fails
Anyone got an idea on how to fix this????

Peter.

[sql7] DTS and disappearing indexes
I have noticed that if I use the Microsoft ODBC driver for SQL Server when I
transfer data from one database to another my indexes disappear. If I pick
other odbc source and then fill in the data source my indexs do not go away.
Anyone else see this behavior? I don`t think it should be working this way.
Thanks,
Dave
I am experiencing a situation where I issue a lengthy SQL command to MS SQL Server 7.0 through MTS and it "disappears" - no errors or recordsets are returned. The command is "SELECT * FROM CUSTOMERS WHERE LASTNAME LIKE 'SMITH%'". When I issue this command from SQL Query Analyzer it takes 27 seconds to return 87 rows. When I issue this exact same command through MTS it does not return at all.
I've used the SQL Profiler to analyze the requests. It shows the commands from MTS starting but they never stop (or at least the profiler never reports them as stopping). The same commands coming from Query Analyzer are reported as starting and stopping without fail.
Here's a twist: I can issue less demanding commands (ie, one that doesn't take so long to process) through MTS and they come back fine. For example, when a user logs into my application, I use an SQL statement to verify the user name and password and status the user as logged in. This is routed through MTS and it comes back fine in less than a second. Same application, same PC, same MTS and SQL server, same SQL database. The only difference is that the CUSTOMERS table has over 800,000 records and the USERS table has only 5 records.
PLEASE HELP!
HELP!!!
I have three servers replicating. One is a publisher and two subscribers. If I put data in the publisher, some of it will disappear after replicating. When data is entered in one of the subscribers, the same thing happens.
Anyone have any ideas??? I am doing a merge replication and all servers are running SQL Server 2000.
Kameron
Ok, I'm new here and I REALLY need some help here.
In my organisation, we have a Server with MSSQL 7 running with some databases. Some of the databases are published for replication.
Now, since Monday, we've been losing databases that are in use! :confused:
The files are disappearing and being marked as suspect in SQL. The physical file has been deleted from the machine even when SQL is running and on some databases are replicating. In one instance, we were making permission changes on a user and it just said that the file is no longer there. And when we checked, the msdb system database had disappeared as well. So now the server is showing up as having no databases. We were able to recover some of them through backups and a handy recovery tool. But now we are helpless as to WHY this is happening. We suspect Virus but we have Norton CorporateEdition running and Liveupdate updating every day.
I've searched the web for any one that had the same problem, but nothing came up. Only some stuff saying that space was an issue, but not on a drive with 21GB remaining and the biggest database is 3GB...
Any help, insight or resolution will be greatly appreciated.
I am running an Access 2000 MDB against a SQL 7 back end, using ODBC linkedtables over a LAN and a WAN. The system has been operational for years withrelatively few problems.Recently, WAN users have been reporting several hundred records disappearingat a time. The records are all sequential, and they're in a table thatcontains about 60,000 records. This all started last week at about the sametime (not sure if before or after) that the WAN went down for a couple ofhours for an unknown reason. Since then, every once in a while, a WAN userwill report that several hundred records in a block are just "missing."Then, an hour or two later, they reappear.Any ideas as to what's going on or what can be done to rectify this?Thanks!Neil

I've been working on this database for some time now. It's an Access 2003 database with a SQL backend. Everything was going well until one of the users noticed her data was disappearing after she send an email. The database has a memo field that gets pasted in the body of an email when it is created. Sometimes, when the user sends an email and goes back into the record, the memo field is blank. I know the field has data in it at the time of the email because it will give you an error if the field is null and you won't be able to send it. And, it goes into a history table with everything the user does with each record. I've checked this history table and it shows that all records in question, an email was sent. I have no idea why the data would disappear in this field. It does not happen all the time. I've performed the same steps and I can't duplicate the problem. There's no code associated with the memo field that deletes it after sending the email. Can anyone think of anything that would cause this?
The problem i am facing here is disappearing data in sql server 2000. I
not sure what is the problem, but it is getting worse and worse. Anyone
can point me to a right direction whether this is a security
vulnerability which i need to download the patch, or is it my computer
is infected with virus., or is it a bug in sql server?
I remember having read somewhere about this problem also, but not sure
in which website already. Anyone, please help!!! Because we are going
to deploy to production server soon, and this is a problem that need to
be solve ASAP..
Thanks in advance...
I am supporting a system that needs to allow users to have access to Temp DB. I set these users up using the GUI, but whenever the server is restarted, these users are wiped out. Is there anyway to keep these users when the server is rebooted?

A user created stored procedure is dropped from system tables where no known drop procedure command is executed.
From ISQL the procedure runs properly after creation but, at sometime during execution the procudure dropped from the system tables.
Any help would be appreciated.

Hello together,
strange things going on:
1. The table statistic shows for example 67 rows in a table, select count(*) only returns 63 rows.
2. Table statistic shows 50 rows, select count(*) returns 55 rows.
In both cases if you do an insert the newly inserted row sometimes can be retrieved by a select statement sometimes not. Row statistics sometimes is updated correctly, sometimes not.
Integrity check for these databases says everything is fine. DBCC CHECKDB, DBREINDEX, UPDATESTATISTICS, ... does not help or says everything is fine.
Already opened a case at HP's Microsoft support and they involved Microsoft itself but all are a little bit clueless at the moment.
As this is our main DB cluster and several databases are affected we had to stop most of our applications since last Thursday and now we are getting a little bit in trouble so any hint is very welcome.
Thanks in advance
PS: Restore is not an option - as all tools say everything is fine all of our backups from the last months include the error. Don't ask why nobody recognized the lost data earlier, seems they were stored but not required for some time.
I am using a hosted MSSQL 2000 database that powers the backend of mywebsite. Website visitors interact with it via ASP pages I havedeveloped. I also have an internal FileMaker 7 database thatperiodically synchs with it via Filemaker's ODBC functionality.Several times now, I have come in one day to discover that my ASP pagesdon't work. When I look into it, one of my MSSQL tables will be missinga few fields. There is nothing in any of my code that sends an ALTERTABLE command or any other command that affects table structure. Thesedeletions of fields is totally random.The most recent example was with a table called FreeTeacherSubs. I justdiscovered today that three fields went missing:HowDidYouHearAboutYES TEXTFollowUpCallOrEmail TEXTHowMaterialsFit TEXTSuffice to say I am baffled! Has anyone ever experienced fieldsdisappearing from their tables?Kevin

I created a simple stored procedure shown below. It works wonderfully. The only problem is that it likes to disappear on me. I am accessing it through a VB.Net program. The system will work fine throughout the day and suddenly it will be gone. I can exit Sql Server Management Studio and come back in and it will still be there so that is not causing it. The database stays connected all the time.
Any suggestions?

I'm not even sure where to post this, but has anyone had a problem with maintenance plans disappearing?
I mean the SSIS package and the job just disappearing....?
I have four servers. Two dev and two prod. I created a pretty simple maintenance plan to backup databases. There are four tasks in the plan. One for each of four databases. Backing each up to a separate file, all in the same folder.
The plan gets associated with a job that has it run daily, every six hours, with no end date.
The plan runs just fine. Then this morning, on one of the servers, the plan and its job are just gone.
This is the second time this has happened. And it's not the same server that it happened on the first time.
Why would a maintenance plan just disappear?
Anyone?

When I enter data into a SQL database and save it, the data that I have just added disapears, but when I close the applicaiton and re-open it, it's still there - is there any reason for this and any way to get it to stay?
Any ideas?
I have set up 80 connections to the SQL Server - mostly through code. People have been successfully using the database, but then when they come in to use their computer and the database the next day, their connection is completely gone! What is that all about? So far this has happened to 2 or 3 different users. Any idea why?
Thanks.
Hi,
We have a number of databases on our SQL Server 2005. One of them, AddressPoint, keeps disappearing completely every few days. I should qualify that - the database name still exists and is visible in Management Studio, but there is no + icon to expand to see the object types.
I can manually restore the database. But we are unable to identify any process that might be deleting the database.
So where do I even start in trying to track down the process that is deleting it? I have not been able to pinpoint a specific time when the deletion might have occurred, as I am not using the database regularly, and neither are our users, yet. The latest deletion definitely occurred within the last 24 hours, but that's as specific as I can be.
Thanks,
Keith.
I'm trying to modify an existing report. But if I make any change at all to the query (anything at all, like add a space), when I switch to the layout tab, the list of fields in the field list disappears. Un-doing the change does not restore the field list. The query runs fine from the data tab and returns a valid resultset.
Any suggestions?
This is with RS 2000 and Visual Studio 2003. Specifically, I'm trying to modify the Sales Pipeline Detail report from CRM.
