mysql多線程的支持問(wèn)題

eveson

創(chuàng)建了100個(gè)線程，100個(gè)數(shù)據(jù)庫(kù)連接，每個(gè)線程有一個(gè)數(shù)據(jù)庫(kù)連接，同時(shí)操作數(shù)據(jù)庫(kù)，這樣就coredump了

1. #0  0x000000000041d5ee in mysql_send_query (mysql=0x41e95c98, query=0x43c98cf0 "select * from T_Test", length=20)

復(fù)制代碼

可以支持了，數(shù)據(jù)庫(kù)連接池搞定。
