I get it. It is the string limitation issue. The sql datatype varchar is nonissue since the documentation says the corresponding stata data type for sql data type varchar is string. Just the fact that some sql columns with type varchar are allowed while some are relieved tells me this is a string limitation issue. I could use _compress but there has to be a variable present before I use _compress. The dilemma is before I can use _compress, the column is alredy lost while loading dataset. Is there a cure to this??? 

One potential solution I can think of is using _compress as option while loading a dataset. Unfortunately, options are not allowed. 

Thanks

> Hello all,
> I use odbc driver to import data from mysql into stata. While running in windows, the column doc_type which is of type varchar in mysql changes into str244 in stata. Unfortunately, in linux machine, when I use odbc to import column doc_type which is type varchar, I get error and I quote "note:doc_type is of a type not supported in Stata;skipped"
