Create a table
SYNOPSIS
mysql_create_table_no_lock()
thd Thread object
db Database
table_name Table name
create_info Create information (like MAX_ROWS)
fields List of fields to create
keys List of keys to create
internal_tmp_table Set to 1 if this is an internal temporary table
(From ALTER TABLE)
select_field_count
is_trans identifies the type of engine where the table
was created: either trans or non-trans.
DESCRIPTION
If one creates a temporary table, this is automatically opened
Note that this function assumes that caller already have taken
exclusive metadata lock on table being created or used some other
way to ensure that concurrent operations won't intervene.
mysql_create_table() is a wrapper that can be used for this.
no_log is needed for the case of CREATE ... SELECT,
as the logging will be done later in sql_insert.cc
select_field_count is also used for CREATE ... SELECT,
and must be zero for standard create of table.

FALSE OK
TRUE error
