Is TSQLQuery.AppleUpdate works with UTF8 string field content?
I fetched a web page and extracted part of its content and appended it
into TSQLQuery record's string field.
The web page content is Chinese in UTF-8 encoding.
I 'writeln' the content before appending it and it appeared normal in
the console.
The database is MYSQL 5.5 on ubuntu Intel 64-bit.
However, when I use MYSQL command to
select * from MYTABLE;
the content appeared as garbage.
I already specified the CHARSET=utf8 in the Create Table SQL.
If I directly issue INSERT statement via MYSQL command prompt, it worked
without garbage.
CREATE TABLE IF NOT EXISTS `PROVIDERS` (
`Key` int(10) unsigned NOT NULL auto_increment,
`CName` varchar(50) default '',
`Name` varchar(50) default '',
`Tel` varchar(50) default '',
`Address` varchar(200) default '',
`WebSite` varchar(80) default '',
`Email` varchar(50) default '',
`ListKey` int(10) signed default 0,
`PageNo` int(10) signed default 0,
PRIMARY KEY (`Key`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
I suspect the problem is in TSQLQuery's generating the Insert statement
which did not take the string as UTF-8.
How do I confirm this suspicion? and how to solve it?
Thanks in advance.
