is_suitable_for_primary_key()

bool is_suitable_for_primary_key	(	KEY_PART_INFO *	key_part,
		Field *	table_field
	)

Check if the given key_part is suitable to be promoted as part of primary key.

Parameters

key_part	- pointer to KEY_PART_INTO which we are checking.
table_field	- Pointer to Field of column used by key_part.

open_table_def()

bool open_table_def	(	THD *	thd,
		TABLE_SHARE *	share,
		const dd::Table &	table_def
	)

Read the table definition from the data-dictionary.

Parameters

thd	Thread handler
share	Fill this with table definition
table_def	A data-dictionary Table-object describing table to be used for opening, instead of reading information from DD.

Note

This function is called when the table definition is not cached in table_def_cache. The data is returned in 'share', which is allocated by alloc_table_share().. The code assumes that share is initialized.

Returns

false OK true Error

open_table_def_suppress_invalid_meta_data()

bool open_table_def_suppress_invalid_meta_data	(	THD *	thd,
		TABLE_SHARE *	share,
		const dd::Table &	table_def
	)

Read the table definition from the data-dictionary.

Parameters

thd	Thread handler
share	Fill this with table definition
table_def	A data-dictionary Table-object describing table to be used for opening.
