查看指定表结构

.schema files

将显示表的创建语句和相关的触发器

CREATE TABLE files (
    'id' TEXT NOT NULL,
    'drive_id' TEXT NOT NULL,
    'name' TEXT NOT NULL,

    'size' BIGINT NOT NULL,
    PRIMARY KEY('id', 'drive_id'),
    FOREIGN KEY('drive_id') REFERENCES drives('id') ON DELETE CASCADE,
    -- Deferred constraint so integrity is checked at the end of the transaction.
    FOREIGN KEY('parent', 'drive_id') REFERENCES folders('id', 'drive_id') ON DELETE CASCADE DEFERRABLE INITIALLY DEFERRED
);
CREATE INDEX files_parent ON files ('parent', 'drive_id');
CREATE TRIGGER file_delete

BEGIN
    INSERT INTO file_changelog ('id', 'drive_id', 'deleted', 'name', 'trashed', 'parent', 'md5', 'size')
    VALUES (OLD.id, OLD.drive_id, 1, OLD.name, OLD.trashed, OLD.parent, OLD.md5, OLD.size);

查看数据表的结构

PRAGMA table_info(table_name);  //将table_name替换为实际表的名称

0|id|TEXT|1||1

2|name|TEXT|1||0
3|trashed|BOOLEAN|1||0
4|parent|TEXT|1||0
5|md5|TEXT|1||0
