Because with that many fields, going from Salesforce to MySQL, I have to trim many of them down from 255 character strings to 20 character VARCHARs in order to stay under the 64k row size limit in MySQL. The source fields are picklists in Salesforce, and they come across as 255 character strings. Also, the default sync schema doesn't seem to get the right length/precision for numerics anyway. Oh, and it tries to create VARCHARs on the MySQL side for BLOB fields >255 chars, which I end up having to manually change to TEXT data types on the MySQL side after the sync. It's a mess. I *wish* I could just hit "sync" columns, but it just doesn't do the job right, and I end up doing a lot of manual clean-up. And, as I mentioned, with several hundred fields, this is a nightmare. I'm getting faster at it by dumping out the XML in the schema editor, then using find & replace, but that's still not ideal. Thoughts? Thanks for your prompt reply!
