In My ClientDataset
IBANNO field In some records are like 9000 8851 0001
(There may be empty strings )
Some records are like 900088510001
(No empty strings)

what is the shortest way to locate a database record
no matter user entry SearchText has empty string or not ?
I want to use something like below code
CDS1.Locate('IBANNO', SearchText,[LoPartialKey])

Thank You
