show slave status 有等价的SQL语句吗

是的，可以使用以下SQL语句来获取与show slave status相同的信息：

SELECT 
    Slave_IO_State, 
    Master_Host, 
    Master_User, 
    Master_Port, 
    Connect_Retry, 
    Master_Log_File, 
    Read_Master_Log_Pos, 
    Relay_Log_File, 
    Relay_Log_Pos, 
    Relay_Master_Log_File, 
    Slave_IO_Running, 
    Slave_SQL_Running, 
    Replicate_Do_DB, 
    Replicate_Ignore_DB, 
    Replicate_Do_Table, 
    Replicate_Ignore_Table, 
    Replicate_Wild_Do_Table, 
    Replicate_Wild_Ignore_Table, 
    Last_Errno, 
    Last_Error, 
    Skip_Counter, 
    Exec_Master_Log_Pos, 
    Relay_Log_Space, 
    Until_Condition, 
    Until_Log_File, 
    Until_Log_Pos, 
    Master_SSL_Allowed, 
    Master_SSL_CA_File, 
    Master_SSL_CA_Path, 
    Master_SSL_Cert, 
    Master_SSL_Cipher, 
    Master_SSL_Key, 
    Seconds_Behind_Master, 
    Master_SSL_Verify_Server_Cert 
FROM 
    information_schema.processlist 
WHERE 
    ID = CONNECTION_ID();

请注意，此SQL语句需要在正在运行的MySQL连接中执行，并且只能返回与当前连接的slave相关的信息。如果您想获取其他slave的状态信息，则需要在该slave上执行相同的查询。
