Question

I get error:

Conversion failed when converting date and/or time from character string.

I call the stored procedure like this:

var result = (from x in db.spStoredProc(sStart, sEnd) select x).ToList();

where sStart and sEnd are strings with this value:

sStart = "CONVERT(date,GETDATE())"

and

sEnd = "DATEADD(d,1,CONVERT(date,GETDATE()))"

The stored procedure has two parameters of type varchar(max)

In the stored procedure I make left join and I use them like this:

where date_expire >= @sStartSQL AND date_expire < @sEndSQL

Why do I get the error?

Answer 1

You can only pass literals as parameters. So SQL Server literally tries to cast this to date:

sEnd = "DATEADD(d,1,CONVERT(date,GETDATE()))"

Instead, pass:

sEnd = DateTime.Now.AddDays(1).ToString("yyyy-MM-dd HH:mm:ss")

as parameter.
