Hello all,
I have to add several records (up to 100) in a single method.
Basically, the user enters some values in a Listbox, with many rows and 10
columns).
When she wants to save, a method loops into all rows and records, and adds
as many records that there are rows in the listbox.
I use this kind of method :
Dim r, c as integer
Dim field, value as string
Dim cursor as Vcursor
' create a non nil cursor with no records in the good table:
Cursor = thedatabase.SQLSelect("SELECT * FROM myTable WHERE myField =
'whatever'", 2, 1, 1)
For r = 0 to ListBox1.listcount - 1
cursor.setblank
for c = 0 to ListBox1.columncount-1
field = ListBox1.heading( c )
value = ListBox1.cell(r, c)
cursor.field(field).setstring value
next
if cursor.update = false then
MsgBox "oops"
end if
Next
But this runs surprisingly slowly. I used to seeing Valentina running much
faster than that.
Thus this kind of method runs fast for updates.
Is there a faster method?
I think that SQLExecutes are too dangerous, because they may update all the
records in the table if the "WHERE" statement is skipped for any reason.
Thanks all
Eric
