• Want to check fields for data fast.

  - by Tom

  We have a database setup that consists of two parts: a static structure, and dynamic additions. For each database, the dynamic can be different, and sometimes we don't have data for all the dynamic fields. Rigt now, we check for empties by looking at the total count of records in the entire table, but we want to move to a more refined method of checking for empties if possible. Is it possible to quickly check through several hundred fields and see which ones are empty and which ones are populated?

I would like to know because I'd like to manually write SQL statements to accompany models changes in the app so that my db's can be kept up to date.

• Returning Null values with COUNT

  - by Randy B.

  With this query, I get a result that is two short of the table because they are not included in count, and I would like get the NULL values in the result. To do this, I am pretty sure I need to use a subquery of some kind, but I am not sure how, since the attribute in question is an aggregate. SELECT Equipment.SerialNo , Name, COUNT(Assignment.SerialNo) FROM Equipment INNER JOIN Assignment ON Assignment.SerialNo = Equipment.SerialNo GROUP BY Equipment.SerialNo, Name

• how do i do very fast inserts to SQL Server 2008

  - by CharlesO

  I have a project that involves recording data from a device directly into a sql table. I do very little processing in code before writing to sql server (2008 express by the way) typically i use the sqlhelper class's ExecuteNoneQuery method and pass in a stored proc name and list of parameters that the SP expects. This is very convenient, but i need a much faster way of doing this. Thanks.
