In our next step, we loop through all tables in that database (feel free to limit the results by playing with GetDatabaseSchema) and create a FlatFileFormat for each of them. We will include all columns except those with datatype Binary or Object. As flatfiles don’t really care about actual data formats, we will just define every column as a string with maximum length. We will also add an annotation with the table’s original name, the list of columns as well as a list of primary keys (we’ll need the latter for a later step :)):
Like most Biml-related things, it’s not that many lines of code, so check it out.
