Hi Simon, Olaf , Garry,
Great news to you all,now i can able to insert 65k docs in second,
only i had done as per Simon and Garry suggestion
1. i freed the array as per suggestion
2. remove 'cmd.Parameters.Add(myparam) as per Garry suggestion.
*here are summary code :inserting 65k in 4-5 sec*
*
*
//Reading text file 1 in
yarray2= filetext.Split(Environment.NewLine)
//Reading text file 1 in
yarray1 = filetext1.Split(Environment.NewLine)
insert:
Dim tx = cons.BeginTransaction()
For y = j To x
Dim strval
strval = Replace(yarray(y) + vbTab + yarray1(y), "'", "''")
strval = Replace(strval, vbTab, "','")
myparam.Value = strval
cmd.CommandText = "INSERT into " & ticket & " VALUES('" & strval
& "')"
//////////' REMOVED cmd.Parameters.Add(myparam)
cmd.ExecuteNonQuery()
Next
tx.Commit()
Array.Clear(yarray, 0, x) ' // FREE ARRAY 1
Array.Clear(yarray1, 0, x) ' // FREE ARRAY 1
tx.Dispose()
j = x + 1
x = x + 10000
If x < Frow1 Then
GoTo insert
Else
tx = cons.BeginTransaction()
Dim m As Integer
m = x - 10000 + 1
For y = m To Frow1
Dim strval
strval = Replace(yarray(y) + vbTab + yarray1(y), "'", "''")
strval = Replace(strval, vbTab, "','")
myparam.Value = strval
cmd.CommandText = "INSERT into " & ticket & " VALUES('" &
strval & "')"
