Replicating a View from MSSQL to MYSQL

     So what it took me to figure out MSSQL to MYSQL replication, we’re not going to use it, per se. Our goal was to condense a multidude of tables down to a single view, then replicate that view from our MSSQL server to a single table on the MYSQL side (which you can replicate a view). However the hitch in the giddy-up was the constraints of the view. The highlights were; it must have a non-clustered unique index, a view cannot contain an “outer join” (crap). There is a host of critera to make an index view in the first place so once we were past that we thought it was clear sailing. Wrong.

So here we sit, the minimal number of views that we can break the data down to, with holding to the constraints of the view is about 4-5. It looks like we will have to replicate the views as tables into MYSQL, then have the website condense them down to display on the page.

It’s not bad, just not what we wanted.
