MYSQL嵌套查询的问题

SELECT customers_id, customers_lastname, customers_firstname, customers_email_address

FROM osc_customers c

where EXISTS (

select 1

FROM osc_money_account

where osc_money_account.customers_id = osc_customers.customers_id

)

ORDER BY c.customers_lastname, c.customers_firstname

LIMIT 30

你2个查询的变量不要一样，不一样就可以了

$q1=msyql_query("")

$q2=msyql_query("")

while($row1=mysql_fetch_array($q1)){

    while($row2=mysql_fetch_array($q2)){

    }

}
