in sql server you coud do:

update mytable set state= substring(state,2,29)

change the "29" to whatever the actual length is.

I am sure mysql must have equivalent syntax.

Repeat for each field, it looks like there is only a handful of them.

As an alternative you could filter the original csv document - isn't that easier?

Or even get a proper CSV scanner that deals with the data that was given!

i'm not a MySql expert but this should work: (based on my similar experience in Sql Server)

UPDATE table_name SET col_name = REPLACE(col_name, '"', '')

For more info on the REPLACE and other string parsing functions, see here: http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_replace
