我正在对 Oracle 数据库尝试一个简单的 INSERT 语句。其中一个值是 VARCHAR2 字段，并且插入语句包含一个 & 符号。我该怎么做呢？我尝试了以下方法：

  1. 将 & 转义为 \& 并设置转义
  2. 设置扫描关闭（这会导致 ORA-00922 丢失或无效选项错误）
  3. 设置定义关闭（这会导致 ORA-00922 丢失或无效选项错误）

还有其他想法吗？

At the bottom of a SQL window there is a button to disable/enable substitution variables:

How I solved it is escaping the & with another &.

For example:

INSERT INTO Foo (Bar) VALUES ('Up && Away');

Works nicely. Thanks for all the help

需要时间熟悉的 PL/SQL Developer 的特性之一是过多的不同窗口类型。

One of these is the COMMAND window, which is basically a SQL*Plus emulator. We can run SQL*Plus commands as well as SQL, so SET ESCAPE, SET DEFINE and indeed SET SCAN OFF work in that window.

你有没有尝试过这样的事情？

INSERT INTO tablex VALUES ('Sid ' || '&' || ' Nancy');

改进我的第一个答案，您的问题与 PL/SQL Developer 有关。如果您在 PL/SQL Developer 命令窗口中执行您的块，您还可以使用标准的 SET DEFINE OFF，它的工作方式与 SQL*Plus 中的相同。

select FUND_NM
FROM PERFORMANCE
WHERE upper(FUND_DESC) in ('My L&' ||'L FUNDS')

I use chr(38) where I need an ampersand in PL/SQL.

addr:= 'mysite.com/order.aspx?no=5678' || CHR(38) || 'id=947';
--above line gives you 'mysite.com/order.aspx?no=5678&id=947';

This is just a SQL Editor issue. To resolve this just compile the procedure with SET DEFINE OFF; . Execution which is PL (executing in server) will not face this issue.
