    update thread set active=0,option='lock',manager='书生' where threadid='7366'
    这个命令通不过,就是option='lock'的问题。why



    是的。以下这些都是
    action add aggregate all 
    alter after and as 
    asc avg avg_row_length auto_increment 
    between bigint bit binary 
    blob bool both by 
    cascade case char character 
    change check checksum column 
    columns comment constraint create 
    cross current_date current_time current_timestamp 
    data database databases date 
    datetime day day_hour day_minute 
    day_second dayofmonth dayofweek dayofyear 
    dec decimal default delayed 
    delay_key_write delete desc describe 
    distinct distinctrow double drop 
    end else escape escaped 
    enclosed enum explain exists 
    fields file first float 
    float4 float8 flush foreign 
    from for full function 
    global grant grants group 
    having heap high_priority hour 
    hour_minute hour_second hosts identified 
    ignore in index infile 
    inner insert insert_id int 
    integer interval int1 int2 
    int3 int4 int8 into 
    if is isam join 
    key keys kill last_insert_id 
    leading left length like 
    lines limit load local 
    lock logs long longblob 
    longtext low_priority max max_rows 
    match mediumblob mediumtext mediumint 
    middleint min_rows minute minute_second 
    modify month monthname myisam 
    natural numeric no not 
    null on optimize option 
    optionally or order outer 
    outfile pack_keys partial password 
    precision primary procedure process 
    processlist privileges read real 
    references reload regexp rename 
    replace restrict returns revoke 
    rlike row rows second 
    select set show shutdown 
    smallint soname sql_big_tables sql_big_selects 
    sql_low_priority_updates sql_log_off sql_log_update sql_select_limit 
    sql_small_result sql_big_result sql_warnings straight_join 
    starting status string table 
    tables temporary terminated text 
    then time timestamp tinyblob 
    tinytext tinyint trailing to 
    type use using unique 
    unlock unsigned update usage 
    values varchar variables varying 
    varbinary with write when 
    where year year_month zerofill 
    这些虽然是,但仍可作为列/表名
    ACTION 
    BIT 
    DATE 
    ENUM 
    NO 
    TEXT 
    TIME 
    TIMESTAMP



    改成这样试试
    update `thread` set `active`= 0,`option`='lock',`manager`='书生' where `threadid`='7366'



    我把option改成了moption了^_^谢谢
