问题 I am trying to calculate the number of minutes between two datetimes using sql ansi-92 . I'm not able to use timestampdiff() function because I get an error response.

Why isn't SQL ANSI-92 standard better adopted over ANSI-89?

问题 At every company I have worked at, I have found that people are still writing their SQL queries in the ANSI-89 standard: select a.id, b.id, b.address_1 from person a, address b where a.id = b.id rather than the ANSI-92 standard: select a.id, b.id, b.address_1 from person a inner join address b on a.id = b.id For an extremely simple query like this, there\'s not a big difference in readability, but for large queries I find that having my join criteria grouped in with listing out the table
