ADO Error - Method 'Execute' of object '_Command' failed

While executing a UPDATE query through ADO i am getting an error message
Run time error '-2147217887 (80040e21)':
Method 'Execute of object '-command' failed.

I am using
 NT 4 OS with SP4, VB6
 ADO object Library 2.1
 Oracle Server & Client 8.1.7

Tips
----
a) While command object executes this error prompted.
b) When i use adInteger instead of adBigInt datatype,
   this error is not encountered.
c) The same adBigInt datatypes working without any error
   in Oracle Server and client 8.0.6
d) Why this Oracle 8.1.7 is not accepted ?

Thanks in advance

If you are going to use dynamic SQL, don't use parameters. Just construct your SQL with the values as part of the string expression.
