Tóm tắt cuộc thi
I need this URGENTLY to help debug and fix a problem I'm having.
I need a simple script which will do the following (pseudo-code):
READ from configuration file, the host, port, user, password of two mysql servers: SERVER1 and SERVER2.
For each DATABASE in SERVER1, repeat:
For each TABLENAME in [url removed, login to view], repeat:
Let T1 represent TABLENAME in [url removed, login to view] and T2 represent TABLENAME in SERVER2.DATABASE.
Get the name of the auto_increment primary key column of T1 (if none defined, skip to next table).
Select the MAX(primary key "PK" value) from T1 and T2
For each ROW in T1 that has a PK value larger than MAX([url removed, login to view]), copy the row from T1 to T2.
Compare the COUNT(*) from T1 and T2, and if they don't match, print a warning.
; end of pseudo-code
