dict_load_sys_table()

void dict_load_sys_table

(

This function is called when the database is booted.

Loads system table index definitions except for the clustered index which is added to the dictionary cache at booting before calling this function.

Parameters

table

in: system table

dict_load_table()

dict_table_t * dict_load_table	(	const char *	name,
		bool	cached,
		dict_err_ignore_t	ignore_err,
		const std::string *	prev_table = nullptr
	)

Loads a table definition and also all its index definitions, and also the cluster definition if the table is a member in a cluster.

Also loads all foreign key constraints where the foreign key is in the table or where a foreign key references columns in this table.

Parameters

[in]	name	Table name in the dbname/tablename format
[in]	cached	true=add to cache, false=do not
[in]	ignore_err	Error to be ignored when loading table and its index definition
[in]	prev_table	previous table name. The current table load is happening because of the load of the previous table name. This parameter is used to check for cyclic calls.

Returns

table, NULL if does not exist; if the table is stored in an .ibd file, but the file does not exist, then we set the ibd_file_missing flag in the table object we return.

dict_load_table_low()

static

Loads a table definition and also all its index definitions.

Loads those foreign key constraints whose referenced table is already in dictionary cache. If a foreign key constraint is not loaded, then the referenced table is pushed into the output stack (fk_tables), if it is not NULL. These tables must be subsequently loaded so that all the foreign key constraints are loaded into memory.

Parameters

[in]	name	Table name in the db/tablename format
[in]	cached	true=add to cache, false=do not
[in]	ignore_err	Error to be ignored when loading table and its index definition
[out]	fk_tables	Related table names that must also be loaded to ensure that all foreign key constraints are loaded.
[in]	prev_table	previous table name. The current table load is happening because of the load of the previous table name. This parameter is used to check for cyclic calls.

Returns

table, NULL if does not exist; if the table is stored in an .ibd file, but the file does not exist, then we set the ibd_file_missing flag true in the table object we return
