I’ ve got a short question. How could I insert values contain a datetime type?
I’ve tried this one:

>update D:\\transmisja\\skawina4\\W\\wkono.dbf set kod_kontr = '21-0003',

Nzwakontr1 = 'Kmiecik Wieslaw', Nzwakontr2 = '' , Adrknth_m ='RADZISZÓW',

Adrknth_u = 'JANA PAWLA II 1', NrDomu='', Nrlok='', Adrknth_k='32-052',

Nr_vat ='   -', Telkontr ='-  -', Nrkonkontr='200 21 0003', Bank ='',

NrKonta = '', Osw = '', Sz = '', Region = '', Upust = 0.0, TerminP = 0, 

Poziomcen =0, PlatnikVAT =.f., Warunki1 ='175/A/00', Warunki2 ='2000.12.30', 

Obwod = '21', Grupa = 'P1', Us_p ='--', Zus_p = .t., Us_r ='IO', Zus_r = .t., 

Rdziel = '--', Rulica ='JANA PAWLA II 1', Dus_p = CTOT('1993-03-12 00:00:00'), 

Dus_r = CTOT('2009-07-15 00:00:00') where kod_kontr='21-0003'

But this one puts blank value into table:

Dus_r = CTOT(‘2009-07-15 00:00:00’)

My short question: What I’m doing wrong?

This is my connection string:

Provider=vfpoledb.1;Data Source=D:\transmisja\skawina4\W\wkono.dbf;Collating Sequence=machine

And it is ado.net connection using by .net 4.0 windows forms c# application

    Looking at the documentation it looks like the datetime is in TZ format so I think by changing to the following it might just start to work:

    Dus_r = CTOT('2009-07-15T00:00:00')

    NOTE T added between date and time

    or perhaps

    Dus_r = CTOT('2009-07-15T00:00:00Z')

    NOTE T added between date and time, and Z after time
