Returns

DB_SUCCESS or error code.

dict_create()

dberr_t dict_create

(

void

)

Creates and initializes the data dictionary at the server bootstrap.

Returns

DB_SUCCESS or error code.

dict_hdr_flush_row_id()

void dict_hdr_flush_row_id

(

void

)

Writes the current value of the row id counter to the dictionary header file page.

dict_hdr_get()

dict_hdr_t * dict_hdr_get

(

mtr_t *

mtr

)

Gets a pointer to the dictionary header and x-latches its page.

Returns

pointer to the dictionary header, page x-latched in: mtr

pointer to the dictionary header, page x-latched

Parameters

mtr

in: mtr

dict_hdr_get_new_id()

		const dict_table_t *	table,
		bool	disable_redo
	)

Returns a new table, index, or space id.

Parameters

[out]	table_id	Table id (not assigned if null)
[out]	index_id	Index id (not assigned if null)
[out]	space_id	Space id (not assigned if null)
[in]	table	Table
[in]	disable_redo	If true and table object is null then disable-redo

dict_is_old_sys_table()

Returns

the new id

dict_sys_read_row_id()

static row_id_t dict_sys_read_row_id ( const byte *  field )

inlinestatic

Reads a row id from a record or other 6-byte stored form.

Returns

row id in: record field

dict_sys_write_row_id()

static void dict_sys_write_row_id ( byte *  field, row_id_t  row_id  )

inlinestatic

Writes a row id to a record or other 6-byte stored form.

Parameters
