To make the code easier to read it is important that the correct compliment of spacing is used.Do not crowd code or remove natural language spaces.Spaces should be used to line up the code so that the root keywords all end on the same character boundary.This forms a river down the middle making it easy for the readers eye to scan over the code and separate the keywords from the implementation detail. Keeping all the keywords aligned to the righthand side and the values left aligned creates a uniform gap down the middle of query.It is certainly more succinct where Celko’s book contains anecdotes and reasoning behind each rule as thoughtful prose.

Create a table in Oracle, by any name, but should match columns specified in fixed length file.Sometimes it will make sense to have the closing parenthesis on a new line at the same character position as its opening partner—this is especially true where you have nested subqueries.When declaring schema information it is also important to maintain human readable code.It makes it much easier to scan the query definition over quickly too.Subqueries should also be aligned to the right side of the river and then laid out using the same style as any other query.
