Re: CONCAT() returns not correct character set
Hi,
Is there any difference between _binary'Binary' and CONVERT('Binary' USING
binary)
mysql SELECT CHARSET(CONCAT(_binary'Bianry',CONVERT('abc' USING latin1)));
+--+
| CHARSET(CONCAT(_binary'Bianry',CONVERT('abc' USING latin1))) |
+--+
| latin1 |
+--+
1 row in set (0.00 sec)
mysql SELECT CHARSET(CONCAT(CONVERT('Bianry' USING binary),CONVERT('abc' USING
latin1)));
+-+
| CHARSET(CONCAT(CONVERT('Bianry' USING binary),CONVERT('abc' USING latin1))) |
+-+
| binary |
+-+
1 row in set (0.00 sec)
In Japan, we have to use many kinds of character set.
eucjpms,ujis for unix
cp932,sjis for Windows
utf8 for Java, MySQL meta data
So, it's a very complicated world.
Hi there,
I tried a few other queries:
first, confirm that what you think is a binary is indeed a binary:
mysql SELECT CHARSET(_binary'Binary');
+--+
| CHARSET(_binary'Binary') |
+--+
| binary |
+--+
1 row in set (0.00 sec)
check the regular text (for completeness' sake)
mysql select charset ('binary');
++
| charset ('binary') |
++
| latin1 |
++
1 row in set (0.00 sec)
OK, so concatenating the 2 should result in a binary according to the manual:
mysql SELECT CHARSET(CONCAT(_binary'Bianry',CONVERT('abc' USING latin1)));
+--+
| CHARSET(CONCAT(_binary'Bianry',CONVERT('abc' USING latin1))) |
+--+
| latin1 |
+--+
1 row in set (0.00 sec)
Hrm, I got the same result you did.
However,
mysql SELECT CHARSET(CONCAT(_binary'Binary','foo'));
+--+
| CHARSET(CONCAT((_binary'Binary'),'foo')) |
+--+
| binary |
+--+
1 row in set (0.00 sec)
works just fine. Why are you converting the text to latin1? It's
already there. That conversion seems to be messing things up.
Perhaps someone can explain why the conversion messes things up --
seems like a bug to me.

default characterset of function string parameter
Dear MySQL fans,
I am checking MySQL 5.0 to use multibyte strings, Japanese.
When I use char type parameter without CHARACTER SET clause,
parameter's character set is not the database character set but
latin1.
17.2.1. CREATE PROCEDURE says:
For character data types, if there is a CHARACTER SET clause
in the declaration, the specified character set and its default
collation are used. If there is no such clause, the database
character set and collation are used. (These are given by the
values of the character_set_database and collation_database
system variables.)
Following is my test:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
mysql SET @@character_set_database=eucjpms;

Re: How to define utf8 function
Hi, Hello. This should be fixed in 5.0.18. See: http://bugs.mysql.com/bug.php?id=13909 17.2.1. CREATE PROCEDURE and CREATE FUNCTION http://dev.mysql.com/doc/refman/5.0/en/create-procedure.html says ... - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - As of MySQL 5.0.18, the server uses the data type of a routine parameter or function return value as follows. These rules also apply to local routine variables created with the DECLARE statement (Section 17.2.9.1, “DECLARE Local Variables”). * Assignments are checked for data type mismatches and overflow. Conversion and overflow problems result in warnings, or errors in strict mode. * For character data types, if there is a CHARACTER SET clause in the declaration, the specified character set and its default collation are used. If there is no such clause, the database character set and collation are used. (These are given by the values of the character_set_database and collation_database system variables.) * Only scalar values can be assigned to parameters or variables. For example, a statement such as SET x = (SELECT 1, 2) is invalid. Before MySQL 5.0.18, parameters, return values, and local variables are treated as items in expressions, and are subject to automatic (silent) conversion and truncation. Stored functions ignore the sql_mode setting. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - I thought that this explanation means function controls CHARACTER SET clause properly from 5.0.18.

Re: MySQL and Unicode
Hi, I have a question. I have read that since MySQL 4.1, VARCHAR type can hold unicode characters. But, it seems that the API of the C library use to send queries to the server still use 'const char*' for the type of the query. So, praticaly, if I have a unicode string stored in C, how can I use it with the C API? Thanks. I use unicode(UTF-8) strings as following. mysql_query( mysql, SELECT inlude Japanese characters(KANJI) ); I think that this might answer your question.

Displaying string including Kanji characters
When I use multi-byte code (especially UTF-8) with data including Kanji (Japanese kanji character) and execute SELECT from mysql client command, the vertical lines(|) of output table aren't aligned as straight lines and the output doesn't look like a table. When I use SJIS code, the problem of sheared line doesn't occur. This is because the display width and the byte number of data always match. To display multi-byte code, not only the count of character and byte, but the display width is also very important. The width of Kanji in EUC-JP, SJIS, and UTF-8 is double the width of alphanumeric characters. As far as I could see, the result of functions involving display, such as LPAD and RPAD, doesn't seem to take the display width of Kanji into account.
