Hi Pinal,

Impressive stuff!

I am currently looking for a tool which verifies whether SQL standards are met in the in the SQL script. For example if a input a stored procedure script then i would like see a report on what all predefined coding standards not met in the stored procedure.

Do you know any tools available like that or let me know pointers to build that kind of a tool.

I agree with most of your guidelines. One that I don’t agree with, is using varchar instead of TEXT. TEXT results in a 16-byte only fixed column, while a varchar(max) could result in 8KB being accessed by the HDD and sent to the resultset. It just serves better to have a huge amount of data off-table and only accessed when needed. Even if a SELECT list is provided, excluding the varchar, the hard drive still has to read all of it into the page before producing the selective list, which is a waste.
Ordinarily, I try to assess the maxlength of a varchar and its usability, and if it’s going to be used infrequently and could be very large, it goes into a TEXT column.

One guideline I use that you didn’t mention, is to have keys at the front of the table, followed by fixed-length columns and variable length columns at the end of the table. Your assessment that varchars are faster to process than chars is only valid when the column length is large. Varchars require the application of a base address with an off-set to reach them. If one places fixed-length columns behind varchars, they, too, will be subject to an off-set. Setting relationships against columns behind varchars places a huge overhead burden on the server.

Just some thoughts.

Hi,

Great document!

I noticed you recommend having table names as ‘plural’ but table is an entity and i think an entity should always be in ’singular’. Correct me if i am wrong

Thanks
Ashok
