dbDelta()

dbDelta(boolean  $errorlevel)

Install tables, stored procedures or whatever in the database.

This method is always called when the version bumps up or for the first initial activation.

Parameters

getMaxIndexLength()

getMaxIndexLength()

Indexes have a maximum size of 767 bytes. Historically, we haven't need to be concerned about that.

As of 4.2, however, we moved to utf8mb4, which uses 4 bytes per character. This means that an index which used to have room for floor(767/3) = 255 characters, now only has room for floor(767/4) = 191 characters.

install()

install(boolean  $errorlevel = false,callable  $installThisCallable = null)

Run an installation or dbDelta within a callable.
