在 SQL*Plus 中截断表
truncate table employee;
从内部使用以下 Java 类
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class t1 {
public static void main(String[] args) {
t1 obj = new t1();
String output = obj.executeCommand();
System.out.println(output);
}
private String executeCommand() {
StringBuffer output = new StringBuffer();
try {
Process p = Runtime.getRuntime().exec(new String[]{"/bin/sh", "-c", "sqlldr scott/tiger control=/home/db1212/x.ctl"});
p.waitFor();
BufferedReader reader
= new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = "";
System.out.println("Return code:"+p.exitValue()+"\n");
while ((line = reader.readLine()) != null) {
output.append(line + "\n");
}
} catch (Exception e) {
e.printStackTrace();
}
return output.toString();
}
}
构建并运行 t1.java
$ javac t1.java
$ java t1
返回
Return code:0

这意味着：
所以在这种情况下
- 成功执行 EX_SUCC = 0
- 一般 SQLLoader 错误，例如“SQLLoader-601：对于 INSERT 选项，表必须为空。表 EMPLOYEE 上的错误”即执行不成功或参数给出 EX_FAIL = 1（Unix，Windows 返回 3 )
- 成功执行/加载，但出现 SQL 错误，例如“ORA-12899: value too large for column "SCOTT"."EMPLOYEE"."DEPT" (actual: 44, maximum: 15)" 返回 EX_WARN = 2
不幸的是文档状态
SQLLoader 返回除零以外的任何退出代码，您应该查阅系统日志文件和 SQLLoader 日志文件以获取更详细的诊断信息。
这意味着没有办法直接将错误作为标准错误、管道等获取，如果 EX_FAIL 或 EX_WARN，您必须验证写入的日志文件。
