Filtering a dataset Verry Slow how can I speed it up

Question

When doing a load from datasource to a UDMatrix on a UDF it is VERY slow
line by line updating each cell etc etc with the result from an SQL Query.
but a loadfromdatasource is Very quick is there a way to do a load from datasource with a filter? (i.e no query)
and hence speed up the whole operation.
Or am I using an incorrect method to load a Matrix..
thanks

Hi
try if this home version of like is useful for you
if you want like "XX*"
Set oCondition = oConditions.Add
    oCondition.BracketOpenNum = 2
    oCondition.Alias = "YourField"
    oCondition.Operation = co_graterEQUAL
    oCondition.CondVal = "XX"
    oCondition.BracketCloseNum = 1
    oCondition.Relationship = cr_AND
    Set oCondition = oConditions.Add
    oCondition.BracketOpenNum = 1
    oCondition.Alias = "YourField"
    oCondition.Operation = co_less_than
    oCondition.CondVal = "XZ"
    oCondition.BracketCloseNum = 2
in theory with this you'll get all the values that begins with XX
Hope it helps you
Kind regards
