// Profile ydf
SQLCA.DBMS = "OLE DB"
SQLCA.LogId = "sa"
SQLCA.AutoCommit = true
SQLCA.DBParm = "PROVIDER='SQLOLEDB',DATASOURCE='１９２.１６８.１.３１',PROVIDERSTRING='database=BYD2016'"
connect using sqlca;

if sqlca.sqlcode<0 then
messagebox("连接失败",sqlca.sqlerrtext,exclamation!)
end if

SQLCA.DBParm = "PROVIDER='SQLOLEDB',DATASOURCE='" + sle_1.text + "',PROVIDERSTRING='database=BYD2016'"
