I think these are not the actual queries sent to SQL Server. You can verify
this with a Profiler trace. You will get these errors if you remove the
quotes around the datetime:
SELECT table1.*,table2.field1,table2.field2,table2.field3 FROM
table1,table2 WHERE table1.field1 = table2.field1 AND
table1.field2='103' AND
table2.TStamp > 12/19/2005 12:20:14 PM ORDER BY table2.TStamp
Also, this problem suggests that you are building a string within your
application and then executing it. You might instead consider using a
parameterized query and command parameters. This can improve performance,
security and provide cleaner code. Also, you won't need to worry about
datetime format issues or embedded quotes.

Hope this helps.
