Re: CONCAT() returns not correct character set
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.

I tested CONCAT() with binary strings and I got strange result.
Manual says:

If the arguments include any binary strings, the result is a binary
string.
But the following test says:
bianry + latin1 latin1 (not bianry)
mysql SELECT CHARSET(CONCAT(_binary'Bianry',CONVERT('abc' USING latin1)));

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.
