sql server - JOIN vs Multiple FROM Tables -


Is there a case where the data will not be returned in an inclusion, which will return from multiple tables with the same circumstances? Include INNER with name names as names by

example

  .ID = Numbers .ID  

VS

Select names as table names, tables in the form of numbers, where name. Name = id ID

An INNER JOIN (as your first example) is always the same Data will be returned such that your Cartesian joins with a WHERE filter that uses the same criteria (your second example).

However, note that this is not right for external Johns, where the zero value is filtered in Cartesian, join the WHERE filter as the criteria for joining it.
