Hsqldb table encoding

问题

How do I set the character encoding for a specific table? E.g:

CREATE TABLE COMMENTS (
    ID INTEGER GENERATED BY DEFAULT AS IDENTITY (START WITH 0, INCREMENT BY 1) NOT NULL,
    TXT LONGVARCHAR,
    PRIMARY KEY (ID)
)

By default it's encoded as ASCII but I'd rather use UTF-8 for this one table.

回答1:

Are you sure that it's encoded as ASCII by default? My reading of it was that it's UTF-8 by default, though I'm open to correction here.

If it's a TEXT table you'll can specify the encoding for the table

SET TABLE mytable SOURCE "myfile;encoding=UTF-8"

回答2:

HSQLDB certainly stores all data in Unicode (with the exception of TEXT tables where you have to specify UTF-8). Therefore you don't need to specify a character encoding for normal tables.

回答3:

The problem is that you must convert all rows before import.
To do this you must export the contents to a file and converter the file into utf-8. Then import it again with utf-8 options.

MyPHPadmin can import it with utf-8 options, (Remember to check for CHARSET=latin1 / latin1 in the file).
