The ALTER TABLE syntax is explained thoroughly on section 7.8 on the manual
pages.
ALTER [IGNORE] TABLE tbl_name alter_spec [, alter_spec ...]
alter_specification:
ADD [COLUMN] create_definition [FIRST | AFTER column_name ]
or ADD [COLUMN] (create_definition, create_definition,...)
or ADD INDEX [index_name] (index_col_name,...)
or ADD PRIMARY KEY (index_col_name,...)
or ADD UNIQUE [index_name] (index_col_name,...)
or ADD FULLTEXT [index_name] (index_col_name,...)
or ADD [CONSTRAINT symbol] FOREIGN KEY index_name (index_col_name,...)
[reference_definition]
or ALTER [COLUMN] col_name {SET DEFAULT literal | DROP DEFAULT}
or CHANGE [COLUMN] old_col_name create_definition
or MODIFY [COLUMN] create_definition
or DROP [COLUMN] col_name
or DROP PRIMARY KEY
or DROP INDEX index_name
or RENAME [TO] new_tbl_name
or ORDER BY col
or table_options

Subject: Dropping a field from a table
Hi !
I'm new to the list, new to MYSQL in general, although not to SQL, and i was
wondering if it is possible to drop a field from a table in MYSQL and what
is the correct sintax to drop it.
I have been searching in the Dubois's MySQL book but it didn't told any
about, or at least i didn't found it.
Thanks in advance
