问题描述
当我尝试在 Oracle SQL Developer 2.1 中执行此语句时，会弹出一个对话框输入替换变量"，要求为 TOBAGO 提供替换值，
update t set country = 'Trinidad and Tobago' where country = 'trinidad &多巴哥';如果不求助于 chr(38) 或 u'trinidad 026 tobago' 两者都掩盖了语句的目的，我该如何避免这种情况?
在查询前调用:
set 定义关闭；或者，hacky:
update t set country = 'Trinidad and Tobago' where country = 'trinidad &'||'多巴哥';<小时>
来自调整 SQL*Plus:><块引用>
SET DEFINE OFF 禁用解析命令以替换替换变量及其值.
When I try to execute this statement in Oracle SQL Developer 2.1 a dialog box "Enter Substitution Variable" pops up asking for a replacement value for TOBAGO,
update t set country = 'Trinidad and Tobago' where country = 'trinidad & tobago';
How can I avoid this without resorting to chr(38) or u'trinidad 026 tobago' which both obscure the purpose of the statement?
Call this before the query:
set define off;
Alternatively, hacky:
update t set country = 'Trinidad and Tobago' where country = 'trinidad &' || ' tobago';
From Tuning SQL*Plus:
SET DEFINE OFF disables the parsing of commands to replace substitution variables with their values.
