1. MSSQL
select @@servername as ServerName,@@VERSION as VersionSQL from sys.databases;
select @@servername as ServerName,name,log_reuse_wait_desc, recovery_model_desc,compatibility_level,@@VERSION as VersionSQL from sys.databases
2. MySQL MariaDB
MariaDB [(none)]> select @@hostname as Hostname, @@version as Version;

3. Oracle Database
SELECT host_name , version FROM V$INSTANCE;
select banner from v$version;
4. Postgresql
SELECT version();
select pg_read_file('/etc/hostname') as hostname, version();
SELECT datname FROM pg_database;
5. Check Version/ Test from Linked Server
--from MSSQL
select @@servername as LocalServer, * from openquery(mssql,'select @@servername as LinkedServer');
select @@servername as LocalServer,@@version as VersionSQL, * from openquery(mssql,'select @@servername as LinkedServer,@@version as VersionSQL');
--for MariaDB MySQL
select @@servername as LocalServer, * from openquery(mariadb,'select @@hostname as LinkedServer');
select @@servername as LocalServer,@@version as VersionSQL, * from openquery(mariadb,'select @@hostname as LinkedServer, @@version as Version');
--from Oracle
select @@servername as LocalServer, * from openquery(oracle,'SELECT host_name as LinkedServer FROM V$INSTANCE');
select @@servername as LocalServer,@@version as VersionSQL, * from openquery(oracle,'SELECT host_name as LinkedServer, version FROM V$INSTANCE;');
select @@servername as LocalServer,@@version as VersionSQL, * from openquery(oracle,'select banner from v$version;');
--from postgresql
select @@servername as LocalServer, * from openquery(postgresql,'SELECT datname as DBPostgreSQL FROM pg_database;');
select @@servername as LocalServer,@@version as VersionSQL, * from openquery(postgresql,'SELECT datname as DBPostgreSQL FROM pg_database;');
