Hello,
could someone help me to explain and resolve this error? Or maybe
it is a bug.

I don't know where latin2_general_ci collation comes from.
Well one table or the column has this collation.
Check your structures.
=> `VnitrniCislo` char(15) character set latin2 default NULL,
shouldn it be
=> `VnitrniCislo` char(15) collate latin2_czech_cs default NULL,

I have seen it too and checked both structures in MySQL Table Editor
and both columns had exactly same definitions. And both tables have
same character set and collation

Nah look at your structrue:
CisloProgramu` smallint(6) NOT NULL default '0',
>>> `Embasing` char(7) collate latin2_czech_cs NOT NULL default '',
>>> `VnitrniCislo` char(15) character set latin2 default NULL,
>>> `Stanice` char(3) collate latin2_czech_cs NOT NULL default '',
Here its just character set latin2
>>> CREATE TABLE `test`.`karty_imp_tmp` (
>>> `PracJmeno` char(30) collate latin2_czech_cs NOT NULL default '',
>>> `VnitrniCislo` char(15) collate latin2_czech_cs default NULL,
And here is it collate latin2_czech_cs
That's causing the error.
Barry
You are right. If I create tables where both columns "VnitrniCislo" have
exactly same definitions, it doesn't throw the error.
Bug must be in the MySQL Table Editor which shows in column details
wrong collations
Thanks, Barry.
