SQL Server SSIS : List Of All System Variables And Their Scope

Shiva — Mon, 01 Mar 2010 22:18:35 +0000

While writing an Error Handler in my SSIS Package today, I was trying to determine what are all the System Variables available to me, to use in my error handler to generate meaningful error message in the application. A quick search did not yield the desired results, but a comprehensive search did. So here it is, in case you were looking for the same thing

Property Precendence in SSIS Config File for FTP Connection Manager Components

Shiva — Fri, 26 Dec 2008 21:14:48 +0000

If you have one or more FTP Connection Manager components in your SSIS package and are using the DtsConfig XML configuration file to set the values for the FTP Connection Manager at execution time, then it will be useful for you to know the connection string property precedence, i.e. which property is given higher priority when SSIS tries to resolved the FTP Connection using the values in the connection properties like ConnnectionString, ServerName and ServerPort. Because knowing this precendence will save you time you spend troubleshooting “wierd” production errors in cases where both ConnectionString and ServerName, ServerPort values are specified and do not match.

Unlike Database connections strings, where the entire connection information is represented by a single string delimited with a semi-colon, the FTP ConnectionString property in SSIS consists of only the FTP Server Name and the Port Number, ex: ftp.yourftpserver.com:21

So what happens if you specify values for both the ConnectionString, as well as the ServerName and ServerPort properties for your FTP Connection Manager in Config File ?

I have tested the 3 separate scenarios and found that the precendence is as follows.

1. ConnectionString property as well as ServerName and ServerPort are populated

SSIS will use the combination of ServerName and ServerPort values and ignore the ConnectionString property value.

2. ServerName and ServerPort only are populated, ConnectionString property is not populated,

SSIS will use the value in the ConnectionString property.

3. ConnectionString property only is populated, ServerName and ServerPort are not populated

SSIS will use the value in the ConnectionString property.

So in 2 out of the 3 cases, SSIS uses the ServerName and ServerPort property values. In other words, if the ServerName and ServerPort properties are populated, it is given higher precence than the value in the ConnectionString property (even if populated).

Free SSIS Package to Generate Database MetaData Documentation

Shiva — Sun, 21 Dec 2008 22:50:06 +0000

Andy Leonard has written this beautiful SSIS Package that you can use to loop through your SQL Server instances, then loop through each database in a SQL Server instance, and finally generate meta data ( columns names, datatypes) documentation for the database objects like tables and views in each database.

Very simple and neat implementation. Link to download the package is at the bottom of the article. The package is free to download, but forces you to register for free on the download DNN site.
