Syntax error in MySQL dump file

[Veerasamy Kaunder]

Hi,
I faced an issue in mysql dump restoration. Upon debugging found that the backup file had syntactical error in one of the insert lines.
example: There is a datetime value partially written ('2)and again correctly specified as given in below insert statement.

Insert into Tab1 Values (xx,xx,'2, '2013-05-20 00:00:00',....)

Because of this syntax error, the backup file failed to restore.
can anybody share the knowledge how that is possible when mysqldump command is used for backup.

Regards,
Veera
