character encoding - Why can't I use a specific collation in MySQL? -


i have table character set latin1 (checked show variables "character_set_database";) , default collation of latin1_swedish_ci (checked show table status;).

i'd run query using collation latin1_general_cs, compiled on system (checked show collation "%_cs";):

select * mytab col rlike '[[:upper:]]' collate 'latin1_general_cs' limit 10;

which gives error:

error 1253 (42000): collation 'latin1_general_cs' not valid character set 'utf8'

even default collation not work:

select * mytab col rlike '[[:upper:]]' collate 'latin1_swedish_ci' limit 10;

error:

error 1253 (42000): collation 'latin1_swedish_ci' not valid character set 'utf8'

whats wrong? because terminal sends data in utf-8? (is "connection in utf-8"?) how can anyway use case sensitive collation? need it, otherwise seems impossible check uppercase letters.

you may find interesting.

differences between utf8 , latin1

i can't i'm expert in area, far can see, utf8 , latin1 encode characters differently. trying collate utf8 using latin1 doesn't make sense.

http://dev.mysql.com/doc/refman/5.0/en/charset-applications.html

whereas:

create database mydb default character set utf8 default collate utf8_general_ci;

is consistent.

update

sorry, re-read question , table using latin1. odd. have tried using utf8 collations?
