Does anyone know anything about this?
There is no EXTRA coluumn.
You're misinterpreting the output from SHOW COLUMNS. That statement
provides information about the columns in a table, but the column names
of the SHOW COLUMNS output do not all corrspond to attributes that
you can set directly when you create the table.
Those you can specify directly:
FIELD (column name)
TYPE (the column type; INT, CHAR, etc.)
NULL (by specifying NULL or NOT NULL)
DEFAULT
KEY (by specifying indexes for the the table)
Those you cannot specify directly:
EXTRA (currently used in SHOW COLUMNS only to indicate whether or not
the column has the AUTO_INCREMENT attribute)
PRIVILEGES (you must set these with a GRANT statement)
Thankful for any help
