hello,

I have a macro which is working fine as test case.But the query returns only one row.
I will change the query to return multiple rows.
I need to change the macro to update data in multiple rows { same column} the output will be same as grid layout in the TOAD.

The macro is as follows , please modify for above.

Private Sub cmdTest_Click()

'Defining variables
Dim cnOra As ADODB.Connection
Dim rsOra As ADODB.Recordset
Dim db_name As String
Dim UserName As String
Dim Password As String

Set cnOra = New ADODB.Connection
Set rsOra = New ADODB.Recordset

db_name = "KRIJGS"
UserName = "bertuser"
Password = "abcxyz123"

'Making an ODBC connection according to ADO
cnOra.Open "DSN=" + db_name + ";UID=" + UserName + ";PWD=" _
& Password + ";"
rsOra.CursorLocation = adUseServer

'Running a query
rsOra.Open "select global_name from global_name", cnOra, adOpenForwardOnly

'Passing on data from the recordset to a variable or cell.
'Notice that the column name or alias is used to address
'data in the recordset.
While Not rsOra.EOF
Worksheets("Sheet1").Range("A1") = rsOra![global_name]
rsOra.MoveNext
Wend

rsOra.Close
rsOra.Open "select sysdate from dual", cnOra, adOpenForwardOnly

While Not rsOra.EOF
Worksheets("Sheet1").Range("A2") = rsOra![sysdate]
rsOra.MoveNext
Wend

'Forgetting to close your connection will sometimes result in
'Dr.Watsons
rsOra.Close
cnOra.Close
Set rsOra = Nothing

End Sub

Replace your While loop with:

Worksheets("Sheet1").Range("A2").CopyFromRecordset rsOra

Open in new window


That will write the full contents of the recordset in one go.

Hi,

Just confirm my understanding.

While Not rsOra.EOF
Worksheets("Sheet1").Range("A2") = rsOra![sysdate]
rsOra.MoveNext
Wend

TO

While Not rsOra.EOF
Worksheets("Sheet1").Range("A2").CopyFromRecordset rsOra
rsOra.MoveNext
Wend

Please confirm.

No, I mean replace:


While Not rsOra.EOF
Worksheets("Sheet1").Range("A2") = rsOra![sysdate]
rsOra.MoveNext
Wend

Open in new window



with:


Worksheets("Sheet1").Range("A2").CopyFromRecordset rsOra

Open in new window

Hello,


It worked just fine.one other doubt ?
My query is big and it is going to next line .

e.g. str = "select somethng from table where condition1
                and condition2 and ....................
                and condition3........."

How do I represent this in the vba ? Is there any option to write a query ?

bond7,

With respect, I answered your original question.

If your SQL statement spans more than one line, then use a line continuator (i.e., the underscore).
