 +For each table in the database the MySQL interpreter may have several
 +table handle instances in use, also in a single SQL query. For each table
 +handle instance there is an InnoDB  'prebuilt' struct which contains most
 +of the InnoDB data associated with this table handle instance.
  
 -	/* Note that in InnoDB, i is the column number. MySQL calls columns
 -	'fields'. */
 -	for (i = 0; i < n_fields; i++) {
 -		const dict_col_t* col = &index->table->cols[i];
 -		templ = prebuilt->mysql_template + n_requested_fields;

 +  A) if the user has not explicitly set any MySQL table level locks:
  
 -		if (UNIV_LIKELY(templ_type == ROW_MYSQL_REC_FIELDS)) {
 -			/* Decide which columns we should fetch
 -			and which we can skip. */
 -			register const ibool	index_contains_field =
 -				dict_index_contains_col_or_prefix(index, i);
 +  1) MySQL calls ::external_lock to set an 'intention' table level lock on
 +the table of the handle instance. There we set
 +prebuilt->sql_stat_start = TRUE. The flag sql_stat_start should be set
 +true if we are taking this table handle instance to use in a new SQL
 +statement issued by the user. We also increment trx->n_mysql_tables_in_use.
  
 -			if (!index_contains_field && prebuilt->read_just_key) {
 -				/* If this is a 'key read', we do not need
 -				columns that are not in the key */
 +  2) If prebuilt->sql_stat_start == TRUE we 'pre-compile' the MySQL search
 +instructions to prebuilt->template of the table handle instance in
 +::index_read. The template is used to save CPU time in large joins.
  
 -				goto skip_field;
 -			}
 +  3) In row_search_for_mysql, if prebuilt->sql_stat_start is true, we
 +allocate a new consistent read view for the trx if it does not yet have one,
 +or in the case of a locking read, set an InnoDB 'intention' table level
 +lock on the table.
  
 -			if (index_contains_field && fetch_all_in_key) {
 -				/* This field is needed in the query */
 +  4) We do the SELECT. MySQL may repeatedly call ::index_read for the
 +same table handle instance, if it is a join.
  
 -				goto include_field;
 -			}
 +  5) When the SELECT ends, MySQL removes its intention table level locks
 +in ::external_lock. When trx->n_mysql_tables_in_use drops to zero,
 + (a) we execute a COMMIT there if the autocommit is on,
 + (b) we also release possible 'SQL statement level resources' InnoDB may
 +have for this SQL statement. The MySQL interpreter does NOT execute
 +autocommit for pure read transactions, though it should. That is why the
 +table handler in that case has to execute the COMMIT in ::external_lock.
  
 -			if (bitmap_is_set(table->read_set, i) ||
 -			    bitmap_is_set(table->write_set, i)) {
 -				/* This field is needed in the query */
 +  B) If the user has explicitly set MySQL table level locks, then MySQL
 +does NOT call ::external_lock at the start of the statement. To determine
 +when we are at the start of a new SQL statement we at the start of
 +::index_read also compare the query id to the latest query id where the
 +table handle instance was used. If it has changed, we know we are at the
 +start of a new SQL statement. Since the query id can theoretically
 +overwrap, we use this test only as a secondary way of determining the
 +start of a new SQL statement. */

 -in ::external_lock. When trx->n_mysql_tables_in_use drops to zero,
 - (a) we execute a COMMIT there if the autocommit is on,
 - (b) we also release possible 'SQL statement level resources' InnoDB may

 +   BACKGROUND INFO: HOW A SELECT SQL QUERY IS EXECUTED
 +   ---------------------------------------------------
 +The following does not cover all the details, but explains how we determine
 +the start of a new SQL statement, and what is associated with it.
 +
 +For each table in the database the MySQL interpreter may have several
 +table handle instances in use, also in a single SQL query. For each table
 +handle instance there is an InnoDB  'prebuilt' struct which contains most
 +of the InnoDB data associated with this table handle instance.
 +
 +  A) if the user has not explicitly set any MySQL table level locks:
 +
 +  1) MySQL calls ::external_lock to set an 'intention' table level lock on
 +the table of the handle instance. There we set
 +prebuilt->sql_stat_start = TRUE. The flag sql_stat_start should be set
 +true if we are taking this table handle instance to use in a new SQL
 +statement issued by the user. We also increment trx->n_mysql_tables_in_use.
 +
 +  2) If prebuilt->sql_stat_start == TRUE we 'pre-compile' the MySQL search
 +instructions to prebuilt->template of the table handle instance in
 +::index_read. The template is used to save CPU time in large joins.
 +
 +  3) In row_search_for_mysql, if prebuilt->sql_stat_start is true, we
 +allocate a new consistent read view for the trx if it does not yet have one,
 +or in the case of a locking read, set an InnoDB 'intention' table level
 +lock on the table.
  
 -	//ut_ad(field == table->field[i]);
 -	ut_ad(clust_index->table == index->table);
 +  4) We do the SELECT. MySQL may repeatedly call ::index_read for the
 +same table handle instance, if it is a join.
  
 -	col = dict_table_get_nth_col(index->table, i);
 +  5) When the SELECT ends, MySQL removes its intention table level locks
 +in ::external_lock. When trx->n_mysql_tables_in_use drops to zero,
 + (a) we execute a COMMIT there if the autocommit is on,
 + (b) we also release possible 'SQL statement level resources' InnoDB may
 +have for this SQL statement. The MySQL interpreter does NOT execute
 +autocommit for pure read transactions, though it should. That is why the
 +table handler in that case has to execute the COMMIT in ::external_lock.

 -	templ->clust_rec_field_no = dict_col_get_clust_pos(col, clust_index);
 -	ut_a(templ->clust_rec_field_no != ULINT_UNDEFINED);
 +  B) If the user has explicitly set MySQL table level locks, then MySQL
 +does NOT call ::external_lock at the start of the statement. To determine
 +when we are at the start of a new SQL statement we at the start of
 +::index_read also compare the query id to the latest query id where the
 +table handle instance was used. If it has changed, we know we are at the
 +start of a new SQL statement. Since the query id can theoretically
 +overwrap, we use this test only as a secondary way of determining the
 +start of a new SQL statement. */

 -The following does not cover all the details, but explains how we determine
 -the start of a new SQL statement, and what is associated with it.
 +		long_true_varchar = 0;
  
 -For each table in the database the MySQL interpreter may have several
 -table handle instances in use, also in a single SQL query. For each table
 -handle instance there is an InnoDB  'prebuilt' struct which contains most
 -of the InnoDB data associated with this table handle instance.
 +		if (field->type() == MYSQL_TYPE_VARCHAR) {
 +			col_len -= ((Field_varstring*) field)->length_bytes;
  
 -  A) if the user has not explicitly set any MySQL table level locks:
 +			if (((Field_varstring*) field)->length_bytes == 2) {
 +				long_true_varchar = DATA_LONG_TRUE_VARCHAR;
 +			}
 +		}
  
 -  1) MySQL calls ::external_lock to set an 'intention' table level lock on
 -the table of the handle instance. There we set
 -prebuilt->sql_stat_start = TRUE. The flag sql_stat_start should be set
 -true if we are taking this table handle instance to use in a new SQL
 -statement issued by the user. We also increment trx->n_mysql_tables_in_use.
 +		/* First check whether the column to be added has a
 +		system reserved name. */
 +		if (dict_col_name_is_reserved(field->field_name)){
 +			my_error(ER_WRONG_COLUMN_NAME, MYF(0),
 +				 field->field_name);
 +err_col:
 +			dict_mem_table_free(table);
 +			mem_heap_free(heap);
 +			trx_commit_for_mysql(trx);
  
 -  2) If prebuilt->sql_stat_start == TRUE we 'pre-compile' the MySQL search
 -instructions to prebuilt->template of the table handle instance in
 -::index_read. The template is used to save CPU time in large joins.
 +			err = DB_ERROR;
 +			goto error_ret;
 +		}
  
 -  3) In row_search_for_mysql, if prebuilt->sql_stat_start is true, we
 -allocate a new consistent read view for the trx if it does not yet have one,
 -or in the case of a locking read, set an InnoDB 'intention' table level
 -lock on the table.
 +		dict_mem_table_add_col(table, heap,
 +			field->field_name,
 +			col_type,
 +			dtype_form_prtype(
 +				(ulint) field->type()
 +				| nulls_allowed | unsigned_type
 +				| binary_type | long_true_varchar,
 +				charset_no),
 +			col_len);
 +	}
  
 -  4) We do the SELECT. MySQL may repeatedly call ::index_read for the
 -same table handle instance, if it is a join.
 +	/* Add the FTS doc_id hidden column. */
 +	if (flags2 & DICT_TF2_FTS && !has_doc_id_col) {
 +		fts_add_doc_id_column(table, heap);
 +	}
  
 -  5) When the SELECT ends, MySQL removes its intention table level locks
 -in ::external_lock. When trx->n_mysql_tables_in_use drops to zero,
 - (a) we execute a COMMIT there if the autocommit is on,
 - (b) we also release possible 'SQL statement level resources' InnoDB may
 -have for this SQL statement. The MySQL interpreter does NOT execute
 -autocommit for pure read transactions, though it should. That is why the
 -table handler in that case has to execute the COMMIT in ::external_lock.
 +	err = row_create_table_for_mysql(table, trx, false);
  
 -  B) If the user has explicitly set MySQL table level locks, then MySQL
 -does NOT call ::external_lock at the start of the statement. To determine
 -when we are at the start of a new SQL statement we at the start of
 -::index_read also compare the query id to the latest query id where the
 -table handle instance was used. If it has changed, we know we are at the
 -start of a new SQL statement. Since the query id can theoretically
 -overwrap, we use this test only as a secondary way of determining the
 -start of a new SQL statement. */
