◆ fill_partitioning_from_dd()

static bool fill_partitioning_from_dd	(	THD *	thd,

		const dd::Table *	tab_obj
	)

static

Fill TABLE_SHARE with partitioning details from dd::Partition.

Set up as much as possible to ease creating new TABLE instances by copying from the TABLE_SHARE.

Also to prevent future memory duplication partition definitions (names etc) are stored on the TABLE_SHARE and can be referenced from each TABLE instance.

Note that [sub]part_expr still needs to be parsed from [sub]part_func_string for each TABLE instance to use the correct mem_root etc. To be as compatible with the .frm way to open a table as possible we currently generate the full partitioning clause which will be parsed for each new TABLE instance. TODO-PARTITION:

Create a way to handle Item expressions to be shared/copied from the TABLE_SHARE.
On the open of the first TABLE instance, copy the field images to the TABLE_SHARE::partition_info for each partition value.

Parameters

thd	Thread context.
share	Share to be updated with partitioning details.
tab_obj	dd::Table object to get partition info from.

Returns: false if success, else true.

◆ is_spatial_index_usable()

static bool is_spatial_index_usable ( const dd::Index & index )

static

Check if this is a spatial index that can be used.

That is, if there is a spatial index on a geometry column without the SRID specified, we will hide the index so that the optimizer won't consider the index during optimization/execution.

Parameters

index The index to verify

Return values

true	if the index is an usable spatial index, or if it isn't a spatial index.
false	if the index is a spatial index on a geometry column without an SRID specified.

◆ is_suitable_for_primary_key()

bool is_suitable_for_primary_key	(	KEY_PART_INFO *	key_part,

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.

Returns: true - Is suitable for primary key. false - if not.

	)

static

◆ 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.

Note: This function is called from InnoDB, and will suppress errors due to: Invalid collations. Missing FTS parser.

Returns: false OK true Error

◆ prepare_share()

static bool prepare_share	(	THD *	thd,
		TABLE_SHARE *	share,
		const dd::Table *	table_def
	)

static

Finalize preparation of TABLE_SHARE from dd::Table object by filling in remaining info about columns and keys.

This code similar to code in open_binary_frm(). Can be re-written independent to other efforts later.

◆ set_field_list()

static bool set_field_list	(	MEM_ROOT *	mem_root,
		dd::String_type &	str,
		List< char > *	field_list
	)

static

Set field_list.

To append each field to the field_list it will parse the submitted partition_expression string.

Must be in sync with get_field_list_str!

Parameters

[in]	mem_root	Where to allocate the memory for the list entries.
[in]	str	String object containing the column names.
[in,out]	field_list	List to add field names to.

Returns: false on success, else true.

◆ setup_partition_from_dd()

static bool setup_partition_from_dd	(	THD *	thd,
		MEM_ROOT *	mem_root,
		partition_info *	part_info,
