update records in the Ms Access

hi to all,
i have created one table in Ms Access is


string query="create table testtable1(Name Text(50),age Number,email Text(50),phoneno Text(50),sysdate DateTime)";
clsGlobalFields.oledbcon = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ txtdbsName.Text +";persist security Info=false");
clsGlobalFields.oledbcon.Open();
clsGlobalFields.oledbcmd = new OleDbCommand(query, clsGlobalFields.oledbcon);
clsGlobalFields.oledbcmd.ExecuteNonQuery();
clsGlobalFields.oledbcon.Close();


when i am inserting the value in that table,it fine. But when i am updating the value in that table it given the error"Type mismatch".


Actually i have used two update queries

one update query work fine. the query is

string query="update testtable1 set Name = 'mary' , age = 20, email = 'kfolklklklklkll', phoneno = 3455566567, sysdate = '3/21/2007 12:00:00 AM' where Name = 'nithi' AND age = 20 AND email = 'kfolklklklklkll' AND phoneno = 234455666";
clsGlobalFields.oledbcon = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + txtdbsName.Text + ";persist security Info=false");
clsGlobalFields.oledbcon.Open();
clsGlobalFields.oledbcmd = new OleDbCommand(query, clsGlobalFields.oledbcon);
clsGlobalFields.oledbcmd.ExecuteNonQuery();
clsGlobalFields.oledbcon.Close();

this query is working fine.


But when i am include the sysdate in the where condition it will given the error "Type mismatch". the query is


string query="update testtable1 set Name = 'mary' , age = 20, email = 'kfolklklklklkll', phoneno = 3455566567, sysdate = '3/21/2007 12:00:00 AM' where Name = 'nithi' AND age = 20 AND email = 'kfolklklklklkll' AND phoneno = 234455666" AND sysdate = '3/21/2007 12:00:00 AM';
clsGlobalFields.oledbcon = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + txtdbsName.Text + ";persist security Info=false");
clsGlobalFields.oledbcon.Open();
clsGlobalFields.oledbcmd = new OleDbCommand(query, clsGlobalFields.oledbcon);
clsGlobalFields.oledbcmd.ExecuteNonQuery();
clsGlobalFields.oledbcon.Close();

Enclose your date/time literals in # symbols. Single quotes are for text. Presumably the system is implicitly converting the text to a date/time when you're setting a field but it's refusing to compare text to existing date/time values.

Thank u very much for ur kind reply.

Now, my query is working . thank u . thank u very much

with thanks and regards
