Can you use named parameters with an OdbcCommand?
I have a query like this:
string command = @"SELECT COUNT(*) as cnt,
(
SELECT COUNT(*) FROM attend
WHERE (DATEPART(WEEKDAY,start_date) = 2 OR DATEPART(WEEKDAY,start_date) = 6)
AND empl_no = ? and pay_code = '051'
AND start_date BETWEEN ? AND ?
) as frimon
FROM attend as a
WHERE empl_no = ? and pay_code = '051'";
The only way I can figure out to s开发者_运维问答pecify a Parameter is with a ?
(as opposed to using the @name
method with a SQLCommand). This is forcing me to specify the same parameter multiple times (like for empl_no
). Is there a way to use named parameters with OdbcCommands so I can just specify a named parameter once?
Unfortunately no. One way around this would be to roll your own class where you can define your own parameter collection and use token replacement.
