I am referring this document. I require server_id for uuid short function of mysql.
https://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_server_id
How can i print server_id through mysql console? Thanks
You can do it with:
SELECT @@server_id
as @@
points to global-defined variables (not like single @
which is for session-defined variables)
For example,
SELECT CONCAT(@@server_id, UUID());
mysql> SHOW VARIABLES LIKE 'server_id';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| server_id | 1 |
+---------------+-------+
1 row in set (0.01 sec)
