在SQLPlus上执行脚本时，它会打印数字序列而不是输出 [英] When executing a script on SQLPlus, it prints a sequence of numbers instead of output

问题描述

我试图在SQL PLus上执行脚本，这很简单.

I'm trying to execute a script on SQL PLus, it's simple.

SET serveroutput ON;
DECLARE
    mode NUMBER(1) := 1;

IF (mode = 1) THEN

    prompt 'HERE'

END IF;

prompt 'fim'

成功连接后，我使用sqlplus user/pw@db和@myscript.sql从SQLPlus调用脚本.但是输出对我来说很奇怪:

I call the script from SQLPlus using sqlplus user/pw@db and @myscript.sql after a successful connection. But the output is strange for me:

Conectado a:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options

SQL> @myscript.sql
 9
 10
 11

并且它将继续无限期地打印此序列. 我在做什么错了?

And it continues to print this sequence indefinitely. What am I doing wrong?

推荐答案

从您已编辑的问题开始……您必须在新行上用/终止PL/SQL块，以使其结束并运行，否则SQL * Plus将继续提示输入更多行代码(这是您看到的数字). 文档显示了如何运行PL/SQL块.而且prompt是SQL * Plus命令，因此您不能在PL/SQL块内使用它.您也没有正确的块语法:

From your edited question... you have to terminate the PL/SQL block with a / on a new line to make it end and run, otherwise SQL*Plus will keep prompting for more lines of code (which is the numbers you're seeing). The documentation shows how to run PL/SQL blocks. And prompt is a SQL*Plus command so you can't use it inside a PL/SQL block. You also don't have your block syntax right:

SET serveroutput ON;
DECLARE
    mode NUMBER(1) := 1;
BEGIN
    IF mode = 1 THEN
        DBMS_OUTPUT.PUT_LINE('HERE');    
    END IF;
END;
/

prompt fim
