Hey Semin, thanks for the reply!

I found that some data for some fields contain 'garbage' values - so
the schema (field types / lengths etc) are all skewed by these
entries. This creates problems in MySQL, because some index columns
are turned into BLOB datatypes... I am thinking that running the
script on 10 or so 'good' structures should be enough to 'finalize'
the schema, allowing us to identify bad structures when they fail to
load into the given schema...

BTW, do you run incremental updates of DB-loader?

P.S. I hope you don't mind, I mailed your reply back to the OpenMMS
mailing list.
