Datetime values are not strings, but binary values. Strings can be
implicitly converted to dates, but there is no datetime interpretation
of the string '%MMColParam2%'. I don't know what you intended the
% to mean, but they don't mean anything to SQL Server in this context.
The same goes for
OriginationNumber Like 'MMColParam'
This will give a match if you have an origination number with the exact
of the strnig 'MMColParam'.
Maybe you meant something like:
SELECT OriginationNumber, DestinationNumber, StartTime, State, Duration
FROM dbo.IpPbxCDR
WHERE OriginationNumber Like @MMColParam or
DestinationNumber Like @MMColParam and
StartTime Between @MMColParam2 AND @MMColParam3
Although, you may be thinking of MMcolParam as parameters in your web
page. In such you need to pass them as parameters to SQL.
By the way, what is the intended logic? The above will not consider
StartTime if there is a match in OriginationNumber, only if there is
a match in DestinationNumber.
