mysqldump of one table?

[anna soobrattee]

hi

i want to dump the contents of one table into a text file ... can you tell me what 
i've done wrong ?

i tried :

mysqldump --opt --tables studenttable > myfile.txt
mysqldump --opt --databases [studenttable] > myfile.txt
mysqldump --opt database [studenttable] > myfile.txt

but all these result in an error ... i can dump the whol database but not the table 
studenttable 

thanks
anna
