Using the Script Component as a Conditional Split

This is a quick walk through on how you can use the Script Component to perform Conditional Split like behaviour, splitting your data across multiple outputs. We will use C# code to decide what does flows to which output, rather than the expression syntax of the Conditional Split transformation. Start by setting up the source.… Continue reading Using the Script Component as a Conditional Split

Logging connection strings

If you some of the dynamic features of SSIS such as package configurations or property expressions then sometimes trying to work out were your connections are pointing can be a bit confusing. You will work out in the end but it can be useful to explicitly log this information so that when things go wrong… Continue reading Logging connection strings

Escaping In Expressions

The expressions language is a C style syntax, so you may need to escape certain characters, for example: "C:\FolderPath\" + @VariableName Should be "C:\\FolderPath\\" + @VariableName Another use of the escape sequence allows you to specify character codes, like this \xNNNN, where NNNN is the Unicode character code that you want. For example the following… Continue reading Escaping In Expressions

Data Flow Property Expressions Property expressions within the data flow are not immediately obvious. Whilst most pipeline or data flow components do support them for their properties, the expression is not generally exposed through the component user interface, neither is the Expressions property shown properties grid for the component. Property expressions are only available at… Continue reading Expressions

Generating Surrogate Keys

(By Jamie Thomson) Introduction Surrogate keys are generally considered fundamental building blocks of a data warehouse. They are used as identifiers for dimensional members and enable us to manage slowly changing dimensions. SSIS does not contain a built in component for generating surrogate keys but there is still a mechanism for doing it – the… Continue reading Generating Surrogate Keys
