How to get SELECT COERCIBILITY(xxx)=1?
Hi there.
In
http://dev.mysql.com/doc/refman/5.6/en/charset-collation-expressions.html
It says:
「The concatenation of two strings with different collations has a coercibility of 1.」
What is 「The concatenation of two strings」? CONCAT?
But I can't get '1' from any result of COERCIBILITY(CONCAT(xx,xx)).
How can I get SELECT COERCIBILITY(xxx)=1?
Any help is appreciated.
