Description:
Using Ubuntu AMD 64-bit Karmic Koala 9.10 with MWB 5.2.28 Ubuntu/Debian 64-bit for 9.10
Server is mysqld 5.1.37-1 Ubuntu 5.4

Using the Alter Table feature in SQL Development.

1. Works OK to change a column name.
2. Fails on new index creation:  ndx_long_desc (index name), long_desc (field name)  
3. In the bottom display window: No changes to object were detected. SQL: (no SQL shows)

No matter how the index is named and columns selected, no ALTER SQL is generated.

Thanks,

Ken Wagner

How to repeat:
Create a table then use ALTER TABLE to create a new index.

Suggested fix:
Fix coding.
