I've been using SLAB for a few years now. I am just starting to implement the SqlDatabase sink. I am interested in extending the database table (defaults to Traces) it writes to. I browsed this site for answers and came across some users comments about passing custom fields. I'm familiar with extending the Payload but am interested in adding specific columns to the Traces table. I'm aware that this affects the stored proc that writes to the table and am glad to see that it is now possible to pass in a name of a stored proc to use. Is this as "simple" as using my custom proc to parse the payload for the fields I'm interested in to insert them into my custom columns? Thanks for any help in advance. I'm glad to see some interest and support in SLAB after MS stopped developing it.
