This driver only supports the original MySQL driver in transactional mode. It
|
|
is deprected in PHP version 5.5 and removed in PHP version 7. It is deprecated
|
|
as of ADOdb version 5.20.0. Use the mysqli driver instead, which supports both
|
|
transactional and non-transactional updates
|
|
|
|
Requires mysql client. Works on Windows and Unix.
