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'
