I want to write a variable say testVar in PostExecute of my script. I also want to read the same variable at the start of my script block.
How to specify this variable in the script transformation editor
ReadOnlyVariables = ????
WriteOnlyVariables = ???
If i just define
WriteOnlyVariables = testVar
will it work . I mean i cannot use testVar in both read & write
Any suggestions...
Thanks
Hi,
I am trying to develop a SSIS package which will read the records from the flat file and insert them into a destination table. I have some validations written in script component. I have declared two Read Write variables with package level scope. when i try to assign a value to the variable in the script component and run the package, the package throws me an error "The collection of variables locked for read and write access is not available outside of PostExecute".
What should be done to over come the problem please help me on this regard
Thanks

Hello all,
I have been struggling trying to read and/or write package level variables from within my custom task. I'd like to be able to get and set values from within the Execute method of my custom task. I have searched this forum and the books online and can't seem to find the answer. I thought maybe I could use an expression on my task (mapping the package variable to a custom task public property) but that doesn't seem to be working for me. I also would have thought I could use the VariableDispenser object from within my task but the collection is empty. I have 3 package level variables configured and can't seem to find a way to access them (with intentions of getting/setting). Could someone point me to a good doc or provide an example that may accomplish this? Thanks!
(I'm using package level variables as a means of passing simple information between tasks that are not using a DB, if there is a better way I'm open to suggestions.)

I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.
From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"
Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)
I "sometimes" get the following error:
OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.
Help would be appreciated!
I have seen other posts on this but, not able to relate the solution to my scenario.
Hi All,
I have seen a few other people have this error.
Package works fine when run from BIDS, DTExec, dtexecui. When I schedule it, It get these random errors. (See below)
The main culprit is a variable called "RecordsetFileDIR" which is set using an expression. (@[User::_ROOT] + "RecordSets\")
A number of other variables use this as part of their expression and as they all fail, pretty much everything dies.
I have installed SP1 (Not Beta) on server. Package uses config files to set the value of _ROOT.
The error does not always seem to be with this particular variable though. Always a variable that uses an expression but errors are random. Also, It will run 3 out of 10 times without a problem. I am the only person on the server at the time.
Any ideas?
Cheers,
Crispin

Database B: 91812 7621589 315822
A query runs on database has a significant larger read and write.. I don;t understand why this is happening? even though these two database have the same structure?? it has the same execution plan as well..
How can i solve this issue?

Hello,
We currently run sql 2005 server and also sql express in our dev environments. We use sql express as an offline store (smart client). We have a similar/exact schema on the sql 2005 server and also the express.
We use the auto attach feature to connect to the express version of the database. Both the developer machines and the one that is running the sql 2005 server have exactly the same hardware configuration. The only difference may be that the server box is not running the VS.Net environment. The disk space etc is pretty much the same. Actually we run another database server(DB2) on the 2005 server machine.
We have observed that sql express is much slower and queries execute much slower aswell. For example, this may not be a totally scientific way of checking but a long running query on the server took only 2 minutes while on express it took longer than 9 minutes. The schema and data etc are the same.
Is there something we need to look into as far as read write speed/performance goes ?
TIA,
Avinash
Hi,

Okay, maybe I'm getting ahead of myself.
Using SQL Server Express, VWD and .net 2.0 I've figured out how to drop a Table Column Constraint or Default Value/Binding and then Create it again using a stored procedure. What I can't figure out is how to retrieve that column's constraint value and write it to, say a label, in an aspx page, simply for reference. Is it possible? In this case the Data Type of the column is money.
I'm using it to perform a calculation to a column with a value that the user inserts into another column. (Column1(user input) minus Column2(with Default Value) = Column3(Difference). I just want to read Column2's Default Value for reference so I know whether to change it or not.
Hi,

How does one go about creating such a setup? How does the database where writes are allowed replicated the data to the read only database server?
Hi,I would like to use database locking mechanism to control access to anexternal resource (like file system).What I need is1. an exclusive (write) lock conflicting with any access to theresource (both for read and write)2. non-exlusive (read) lock conflicting with writes onlyHow this could be done?I'd appreciate any reply.Vadim

Hello Guys,
in SSIS I want to get a set of data and do some modifications on it before I insert it into the destinatipn. So far so good. Some of the modifications will include comparisions between two columns and if certain field is NULL then I want to get the value from the other one I was comparing to. When using conditional splits, I only get the rows to be redirected so that I can do whatever next. However, I want like use the variables as a storage so that I can put the value of one of the two columns in this variable which will be actually loaded into the destination finally. Any help?
Thanks

Hello,
Any help here much appreciated.
I am using sql server 2000 to perform address cleansing. there is a point in my scripting when a table i pass values to becomes read/write.
i suspect this is when i run a cursor through the table.
Is anyone able to confirm for me whether running a cursor changes a table's properties?
Many thanks.
Tim
Ps as the table seems to be read/write it is harder to tell if NULLs are in the table and this is messing with joins I have further down the track.
Hello,I'm relatively new to the database world so please forgive me inadvance for my ignorance. I have recently been tasked at my job withfinding a tool that will perform the following tasks: 1) extractschemas from a db, 2) produce a difference report between schemas fromtwo databases, and 3) synchronize two schemas. The purpose is forproduct upgrades during which an existing database schema will need tobe synchronized with a baseline schema.The tool must support the following database vendors (versions givenin parenthesis): Oracle (8i/9i), Sybase (12.x), Informix (9.x), MSS2000, and IBM DB2 (7/8).I have spent the last several days downloading and researching avariety of tools such as Aqua Data Studio, DbVisualizer, DBExplorer,DBDiff, and AdeptSQL. I thought it would be a good idea to post amessage to a few database newsgroups and ask for any recommendationsdatabase developers may have.So if anyone has any recommendations on such a tool or softwarepackage, I would greatly appreciate any information.Thanks!Chad Smith

Hi,I have a web app, that runs fine, except for one particular section that uses a class called by an event in the code behind. The class resides as a dll in the bin folder.

I created an asymmetric key
