Function Documentation

check_engine_condition()

static bool check_engine_condition ( partition_element *  p_elem, bool  table_engine_set, handlerton **  engine_type, bool *  first  )

static

check_partition_dirs()

bool check_partition_dirs

(

partition_info *

part_info

)

fill_partition_tablespace_names()

bool fill_partition_tablespace_names	(	partition_info *	part_info,
		Tablespace_hash_set *	tablespace_set
	)

Fill the Tablespace_hash_set with the tablespace names used by the partitions on the table.

Parameters

part_info	- Partition info that could be using tablespaces.
tablespace_set	- (OUT) Tablespace_hash_set where tablespace names are collected.

Returns

true - On failure.

false - On success.

has_external_data_or_index_dir()

bool has_external_data_or_index_dir

(

partition_info &

pi

)

Predicate which returns true if any partition or subpartition uses an external data directory or external index directory.

Parameters

pi	partitioning information

Return values

true	if any partition or subpartition has an external data directory or external index directory.
false	otherwise

has_same_column_order()

static bool has_same_column_order ( List< Create_field > *  create_list, Field **  field_array  )

static

partition_info_compare_column_values()

static int partition_info_compare_column_values ( const part_column_list_val *  first, const part_column_list_val *  second  )

static

strcmp_null()

static bool strcmp_null ( const char *  a, const char *  b  )

static

helper function to compare strings that can also be a NULL pointer.

Parameters

a	char pointer (can be NULL).
b	char pointer (can be NULL).

Returns

false if equal

Return values

true	strings differs
false	strings is equal

validate_partition_tablespace_name_lengths()

bool validate_partition_tablespace_name_lengths

(

partition_info *

part_info

)

Check if all tablespace names specified for partitions have a valid length.

Parameters

part_info

Partition info that could be using tablespaces.

Returns

true One of the tablespace names specified has invalid length and an error is reported.

false All the tablespace names specified for partitions have a valid length.

validate_partition_tablespace_names()

bool validate_partition_tablespace_names	(	partition_info *	part_info,
		const handlerton *	default_engine
	)

Check if all tablespace names specified for partitions are valid.

Do the validation by invoking the SE specific validation function.

Parameters

part_info	Partition info that could be using tablespaces.
default_engine	Table level engine.

Returns

true One of the tablespace names specified is invalid and an error is reported.

false All the tablespace names specified for partitions are valid.

warn_if_dir_in_part_elem()

static void warn_if_dir_in_part_elem ( THD *  thd, partition_element *  part_elem  )

static

Check if we allow DATA/INDEX DIRECTORY, if not warn and set them to NULL.

Parameters

thd	THD also containing sql_mode (looks from MODE_NO_DIR_IN_CREATE).
part_elem	partition_element to check.
