This program is still beta. Testers wanted.
|
||||
Known bugs are:
|
||||
|
||||
=over 4
|
||||
|
||||
=item Poor doublequotation.
|
||||
=item * Possible problems with the timestamp data.
|
||||
|
||||
PostgreSQL does not accept incorrect date/time values like B<2002-00-15>,
|
||||
while MySQL does not care about that. Currently my2pg cannot handle this
|
||||
issue. You should care yourself to convert such a data.
|
||||
|
||||
=item * Use -s option if your numeric data are broken during conversion.
|
||||
|
||||
My2pg attempts to convert MySQL timestamps of the form B<yyyymmdd> to
|
||||
B<yyyy-mm-dd> and B<yyyymmddhhmmss> to B<yyyy-mm-dd hh:mm:ss>. It performs
|
||||
some heuristic checks to ensure that the month,day,hour,minutes and seconds have
|
||||
values from the correct range (0..12, 0..31, 0..23, 0..59, 0..59 respectively).
|
||||
It is still possible that your numeric values that satisfy these conditions
|
||||
will get broken.
|
||||
|
||||
=item * Possible problems with enclosing identifiers in double quotes.
|
||||
|
||||
All identifiers such as table and column names should be enclosed in double
|
||||
quotes. Program can't handle upper-case identifiers,
|
||||
like DBA. Lower-case identifiers are OK.
