How to Get an RDBMS Server Version with SQL

Do you need to know what RDBMS Server version you’re on, and you only have SQL at your disposal? No problem. Most RDBMS provide you with that information in some form of meta data table.

Here’s how:

-- CockroachDB
select version();

-- Db2
select service_level from table (sysproc.env_get_inst_info()) t

-- Derby
select getdatabaseproductversion() from (values (1)) t (a);

-- Exasol
select param_value 
from exa_metadata 
where param_name = 'databaseProductVersion';

-- Firebird
select rdb$get_context('SYSTEM', 'ENGINE_VERSION')
from rdb$database;

-- H2
select h2version(); 

select * from m_database;

select character_value
from information_schema.sql_implementation_info
where implementation_info_name = 'DBMS VERSION'

-- Informix
select dbinfo('version', 'full') from systables where tabid = 1;

-- MariaDB
select version();

-- MemSQL (SingleStore)
select version();

-- MySQL
select version();

-- Oracle
select * from v$version;

-- PostgreSQL
select version();

-- Snowflake
select current_version();

-- SQL Server
select @@version;

-- SQLite
select sqlite_version();

-- Teradata
select infodata from dbc.dbcinfov where infokey = 'VERSION'
