如何避免在 Oracle SQL Developer 中使用 'trinidad & 进行变量替换多巴哥'

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?

解决方案

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';

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?

解决方案

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.
