请问两个数据库怎么连接?？

你可以这么做
transaction mytrans1,mytrans2
mytrans1=create transaction
mytrans2=create transaction
mytrans1.dbms="驱动程序类型"
mytrans1.dbparm="这里填连接sql6.5的字串"
mytrans2.dbms="驱动程序类型"
mytrans1.dbparm="这里填连接sql7.0的字串"
connect using mytrans1;
connect using mytrans2;
剩下的你知道该怎么做了？

eg:
transaction mytrans1,mytrans2
mytrans1=create transaction
mytrans2=create transaction
mytrans1.dbms = "odbc"
mytrans1.autocommit = false
mytrans1.dbparm = "connectstring=''dsn=yourdsnforsql6.5db''"
connect using mytrans1;
if mytrans1.sqlcode = -1 then
messagebox("",yourmessage)
disconnect using mytrans1;
halt
end if

mytrans2.dbms = "odbc"
mytrans2.autocommit = false
mytrans2.dbparm = "connectstring=''dsn=yourdsnforsql7.0db''"
connect using mytrans2;
