C#

string sql = "select * from   tblVehicle where CAST(floor( CAST( Vehentrytime AS FLOAT ) )AS DATETIME) = '?'";

In the question mark, I need to pass values of DateTime but my DateTime is in string and in short date time format.
In such case how can I pass the parameter of DateTime type?

My string holding the date is in format 11/4/2011 and i need to pass it inside '?' so how to do this?

With regards,

Solution 1

SQL

string sql = "select * from   tblVehicle where CAST(floor( CAST( Vehentrytime AS FLOAT ) )AS DATETIME) = 'yyyy-mm-dd'";

You need to pass date time with 'yyyy-mm-dd' format(of course in string format). This will serve your purpose.

Solution 4

Don't concatenate SQL strings like this, use a parameterized query

This article should explain everything

Just pass it through either as a actual DateTime using a Parametrized query - in which case the problem goes away - or by converting the string into a DateTime first, then convert it back to an SQL compliant datetime string "yyyy-MM-dd hh:mm:ss".

Personally, I would go for the former - it';s a lot easier and more natural.
