在MySQL 8 中,可以通过设置系统变量来限制递归次数。这个系统变量为max_sp_recursion_depth,其默认值为 0,表示没有限制。 设置的代码示例 我们可以使用以下 SQL 语句来修改递归次数限制: SETGLOBALmax_sp_recursion_depth=5; 1. 此命令将递归限制设为 5。当递归调用的层次超过 5 时,MySQL 将返回错误。 检查当...
max_sp_recursion_depth=0 今天在mysql 写存储过程递归调用时,发现老是报错(recovery limit 0(as set by the max_sp_recursion_depth));后来百度下发现 max_sp_recursion_depth设置不对; 这个修改涉及到全局和session级修改, 全局修改的话 需要 有super权限: set global max_sp_recursion_depth=2, session级修...
max_sp_recursion_depth(启动:直接设置;作用范围:全局、会话;动态) 它指的是每个存储过程的最大递归深度。默认值为0(不允许递归),最大值为255。 max_tmp_tables(启动:直接设置;作用范围:全局、会话;动态) 此变量未被使用。 max_user_connections(启动:直接设置;作用范围:全局、会话;动态) 它指的是每个账户同...

I can execute the following query from inside the mysql command client client and it works successfully, but when it is called through a JDBC CallableStatement, it fails telling me that the max_sp_recursion_depth is 0. The max_sp_recursion_depth is set to 10 on the server. Is there some...
