MySQL Count values in a column, Update and replace value which has a limit amount -

-

i have problem mysql update statement. have more 100.000 entries in table. approaches not successful. (see below)

first, want count number of values (thats easy):

select values1 ,count(values1) table group value1 having count(value1) <= 1000;

second, want replace values of column values1 appears <= 1000 times.

so tried these statement:

update table t set t.value1 = "limitamount"  exists (select value1  (select * table) f group f.value1 having count(f.value1) <= 1000);

when tried sql statement, received:

error code 1205. lock wait timeout exceeded. try restarting transaction.

try this

update    table t  set    t.value1 = "limitamount"     exists (select value1 (select * table) f f.value1 = t.value1 group f.value1 having count(f.value1) <= 1000);

notice where f.value1 = t.value1 condition in subquery
