Go prepare statment超过mysql最大数

mysql_stmt_prepare failed! error(1461)Can't create more than max_prepared_stmt_count statements (current value: 16382)

。

给出的回复如下：

max_prepared_stmt_count参数限制了同一时间在mysqld上所有session中prepared 语句的上限。

它的取值范围为“0 - 1048576”，默认为16382。

mysql对于超出max_prepared_stmt_count的prepare语句就会报1461的错误。

调试语句：

mysql> show global status like '%stmt%';
