How to check, that we are using oracle 8i database in jdbc?

Question

在jdbc中，如何检查，我们正在使用oracle 8i数据库？

Answer 1

Connection connection = DriverManager.getConnection(url);
DatabaseMetaData meta = connection.getMetaData();
String product = meta.getDatabaseProductName();
String major = meta.getDatabaseMajorVersion();
String minor = meta.getDatabaseMinorVersion();

Answer 2

您可能必须使用数据库元数据类 。

Answer 3

Run:

select * from v$version

It should produce something like:

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
...

Then it's just a simple matter of parsing that 1st result row.
