【中文标题】SQLPLUS 正在让我的脚本提示：输入行的值【英文标题】：SQLPLUS is making my script to prompt: Enter value for row 【发布时间】：2018-02-07 21:34:12 【问题描述】：

我正在运行最基本的 oracle sql 脚本并在 sqlplus 中运行它。我不明白为什么我的脚本会停止提示我输入“输入行的值”。 FOR LOOP 不是应该在循环之前打开光标吗？

代码是：

/*
  File: myTest.sql
*/

SET SERVEROUTPUT ON SIZE UNLIMITED
SET LINESIZE 140
SET PAGESIZE 60
SET ECHO OFF
SET TERM ON
SET FEEDBACK OFF
SET SHOW ON
SET VERIFY OFF

SPOOL &1

/* Run Parameters & Variables */
DECLARE
text_line         VARCHAR2(4000);

/* Cursors & Row Types */
CURSOR myCursor IS 
  select spriden_pidm, spriden_id, spriden_first_name, spriden_last_name from spriden where spriden_id = '1234';

myCursorRec       myCursor%ROWTYPE;

/* Main Logic */
BEGIN 
  /* Read through all the entries form our data sources. */
  FOR myCursorRec IN myCursor LOOP
    text_line := text_line + myCursorRec.spriden_last_name; 
  END LOOP;
  DBMS_OUTPUT.PUT_LINE('This is the output: ' || text_line || ', ');

END;
/

SPOOL OFF

/* EXIT is needed for Windows environments. */
EXIT

我用这个命令运行它：

sqlplus dbuser/userpass@dbserver @myTest MYSPOOL

输出如下：

为什么我会收到“输入行的值：”提示？？？

【问题讨论】：

ORA-06502 - 数值或数值错误是针对 text_line := text_line + myCursorRec.spriden_last_name;将 + 替换为 || 【参考方案1】：
