Hi everyone,

Dim rs_cust As Recordset
Dim cn_cust As Connection
Dim rs_acco As Recordset
Dim cn_acco As Connection
Dim rs_tran As Recordset
Dim cn_tran As Connection
Dim db, table, msg, sql, login, pass As String

Private Sub Form_Load()
db = "banking"
login = "system"

Set rs_cust = New Recordset
Set cn_cust = New Connection
cn_cust.Open "Provider=OraOLEDB.Oracle.1;" & "Password=" & pass & ";User ID=" & login & ";Data Source=" & db & ";Persist Security Info=True"
cn_cust.CursorLocation = adUseClient
ss = "select * from customer"
Set rs_cust = New ADODB.Recordset
'rs_cust.Open ss, cn, adOpenDynamic, adLockOptimistic


db = "banking"
login = "system"
pass = "manager"
table = "account"
Set rs_acco = New Recordset
Set cn_acco = New Connection
cn_acco.Open "Provider=OraOLEDB.Oracle.1;" & "Password=" & pass & ";User ID=" & login & ";Data Source=" & db & ";Persist Security Info=True"
cn_acco.CursorLocation = adUseClient
ss = "select * from account"
Set rs_acco = New ADODB.Recordset
'rs_acco.Open ss, cn, adOpenDynamic, adLockOptimistic

db = "banking"
login = "system"
pass = "manager"
table = "transection"
Set rs_tran = New Recordset
Set cn_tran = New Connection
cn_tran.Open "Provider=OraOLEDB.Oracle.1;" & "Password=" & pass & ";User ID=" & login & ";Data Source=" & db & ";Persist Security Info=True"
cn_tran.CursorLocation = adUseClient
ss = "select * from transection"
Set rs_tran = New ADODB.Recordset
