>Description:
I was trying to find every row in a table which contains the umlaut
ü (ue). MySQL listed every row which contained the umlaut and rows
which contained the letter y, but no umlaut... Client and server
characterset is latin1.
>How-To-Repeat:
CREATE TABLE test ( name VARCHAR(2) );
INSERT INTO test VALUES ( "a" );
INSERT INTO test VALUES ( "b" );
INSERT INTO test VALUES ( "ü" );
INSERT INTO test VALUES ( "y" );
mysql> SELECT * FROM test WHERE name LIKE "%ü%";
+------+
| name |
+------+
| ü |
| y |
+------+
2 rows in set (0.00 sec)
mysql> SELECT * FROM test WHERE name LIKE "%y%";
+------+
| name |
+------+
| ü |
| y |
+------+
2 rows in set (0.00 sec)
mysql> SELECT * FROM test WHERE name REGEXP ".*ü.*";
+------+
| name |
+------+
| ü |
+------+
1 row in set (0.00 sec)
>Fix:
One can workaround this bug by using REGEXP instead of LIKE. But
than you have to rewrite your queries...
