The block table stores details about block actions of accounts and IP addresses. The block table and block_target replaced the former ip_blocks table.
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).
