Something is wrong using ASP with utf-8/unicode and mysql IF statement. If the results of IF is a date or datetime the output in ASP page is garbled.

How to repeat:
IF(1>2, dayname(now()), dayname(now())) as datum produces wierd text when using response.write(datum) in ASP page.

Result set is binary:

mysql> select dayname(now());
Field   1:  `dayname(now())`
Catalog:    `def`
Database:   ``
Table:      ``
Org_table:  ``
Type:       VAR_STRING
Collation:  binary (63)
Length:     9
Max_length: 6
Decimals:   0
Flags:      BINARY

| dayname(now()) |
| Friday         |
1 row in set (0.00 sec)

My data uses utf-8 and collation Slovenian. It doesn't work from ASP page.

Jerry, the problem is not your data, but the result of the dayname() function.

Jerry, what Jess wants to say is that "binary" is used everywhere in MySQL and it's hard for connector to tell whether to treat "binary" as true binary data or should it be UTF8, for example, like in ad-hoc queries. This is a known problem, please search BugsDB. For now, you can either parse out starting "0x" (as your result is returned in form of "0xcorectresult" or use CAST AS CHAR.

Closing as "Won't fix" as proper patch should be in server.
