DROP TABLE IF EXISTS `simu_mobile_sms_event`; CREATE TABLE `simu_mobile_sms_event` ( `event_id` int8 NOT NULL, `event_type_id` int4 NOT NULL, `bill_flow_id` int4 NOT NULL, `billing_cycle_id` int4 NOT NULL, `billing_area

你提供的是PostgreSQL语法，如果要将其转换成MySQL语法，可以按照以下方式修改：

将”int8”改为”bigint”，将”int4”改为”int”。
将 “varchar(x)” 中的 “x” 改为对应的字符长度。例如，将 “varchar(9)” 改为 “varchar(9)“。
将 “date” 保持不变。
删除所有的 “`” 符号。

修改后的MySQL语法如下：
