What I was trying to do is develop a java application using the ODBC and then
move it to postgres & a linux database when I had everything working.
Unfortunately, I have discovered that there are many differences in the
"standard SQL" that each driver uses.

I could not find any ODBC drivers that us local data that allow the "||"
concatenation symbol.  Most of them use the "+" symbol.  I have found the same
problem with "Memo" vs "text" fields as well.  The ODBC driver for dbase (the
one which seems to work best in my case) also uses the # symbol for dates
while postgres likes the ' symbol.

I guess I have to live with this and write separate query statements for each
implementation.
