SYNOPSIS
sp_use_new_db()
thd thread handle
new_db new database name (a string and its length)
old_db [IN] str points to a buffer where to store the old
database, length contains the size of the buffer
[OUT] if old db was not NULL, its name is copied
to the buffer pointed at by str and length is updated
accordingly. Otherwise str[0] is set to '\0' and length
is set to 0. The out parameter should be used only if
the database name has been changed (see dbchangedp).
dbchangedp [OUT] is set to TRUE if the current database is changed,
FALSE otherwise. A database is not changed if the old
name is the same as the new one, both names are empty,
or an error has occurred.
RETURN VALUE
0 success
1 access denied or out of memory (the error message is
set in THD)
@param[in] thd thread handle

copied to the buffer pointed at by str

Otherwise str[0] is set to '\0' and

should be used only if the database name
has been changed (see dbchangedp).
@param[in] force_switch Flag to mysql_change_db(). For more information,
see mysql_change_db() comment.
@param[out] dbchangedp is set to TRUE if the current database is
changed, FALSE otherwise. The current
database is not changed if the old name
is equal to the new one, both names are
empty, or an error has occurred.
