block テーブル

Blocks against user accounts, IP addresses and IP ranges.

フィールド

bl_id

Primary key.

bl_target

The block target. Foreign key to block_target.bt_id.

bl_by_actor

Actor who made the block.

bl_reason_id

Key to comment_id. Text comment made by blocker.

bl_timestamp

Creation (or refresh) date in standard YMDHMS form. IP blocks expire automatically.

bl_anon_only

If set to 1, block applies only to logged-out users and temporary users.

bl_create_account

Block prevents account creation from matching IP addresses

bl_enable_autoblock

Block triggers autoblocks

bl_expiry

Time at which the block will expire. May be "infinity"

bl_deleted

If true, this block causes the username to be hidden, and the expiry must be infinite. This is denormalized into rev_deleted and the other deleted bitfields (T346716).

bl_block_email

Block prevents user from accessing Special:Emailuser

bl_allow_usertalk

Block allows user to edit their own talk page

bl_parent_block_id

ID of the block that caused this block to exist. Autoblocks set this to the original block so that the original block being deleted also deletes the autoblocks.

bl_sitewide

Block user from editing any page on the site (other than their own user talk page).
