The parameterized query … expects the parameter '@units', which was not supplied

Question

I\'m getting this exception:

The parameterized query \'(@Name nvarchar(8),@type nvarchar(8),@units nvarchar(4000),@rang\' expects the parameter \'@uni

Answer 1

This is a method to be reused with multiple parameters:

public void NullorEmptyParameter(QC.SqlCommand command, string at, string value)
{
    if (String.IsNullOrEmpty(value))
    {
        command.Parameters.AddWithValue(at, DBNull.Value);
    }
    else
        command.Parameters.AddWithValue(at, value);
}

And then you can reuse it for as many commands and params:

NullorEmptyParameter(command, "@Idea_ID", Idea_ID);
NullorEmptyParameter(command, "@Opportunities_or_Idea", Opportunities_or_Idea);
