在Oracle中调用Java程序,注意:java方法必须是static类型的,如果想在JAVA中使用system.out/err输出log. 需要在oracle 中执行"call dbms_java.set_output(5000);".一、helloWord1 编写JAVA程序,也是在SQL/PLUS中写,并执行. create or replace and compile Java source named hello as public class Hello { static public String Message(String name) { return " Hello, " + name...

这个参数，即可解决标识列的问题！下面是-E 参数的详细介绍，-E Specifies that identity value or values in the imported data file are to be used for the identity column. If -E is not given, the identity values for this column in the data file being imported are ignored, and SQL Server automatically assigns unique values based on the seed and increment values specified during table creation. If th...
