Hello Alexey, I have a question about REF_SYSTEM_ID. DROP TABLE IF EXISTS t1; CREATE TABLE t1 (a POINT REF_SYSTEM_ID=10); SELECT G_TABLE_NAME,G_GEOMETRY_COLUMN,SRID FROM INFORMATION_SCHEMA.GEOMETRY_COLUMNS WHERE G_TABLE_NAME='t1'; The above script returns: +--------------+-------------------+------+ | G_TABLE_NAME | G_GEOMETRY_COLUMN | SRID | +--------------+-------------------+------+ | t1 | a | 10 | +--------------+-------------------+------+ This looks correct. The REF_SYSTEM_ID (which is 10) is correctly displayed in the SRID column. But now if I do: SHOW CREATE TABLE t1; It prints: +-------+-------------------------------------------------------------------------------------+ | Table | Create Table | +-------+-------------------------------------------------------------------------------------+ | t1 | CREATE TABLE `t1` ( `a` point DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1 | +-------+-------------------------------------------------------------------------------------+ It does not display the REF_SYSTEM_ID part of the column definition. Looks like a bug from a glance. Can you comment please?
