+ BACKGROUND INFO: HOW A SELECT SQL QUERY IS EXECUTED

+The following does not cover all the details, but explains how we determine

- prebuilt->templ_contains_blob = FALSE;
+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;
- field = table->field[i];
+ 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. */

+ 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->col_no = i;
- 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. */
