How Can I Avoid the 'Enter Substitution Value' Prompt When Inserting Ampersands (&) in Oracle SQL?

Handling Ampersands (&) in Oracle SQL Queries

Oracle SQL's default behavior can cause unexpected prompts when inserting special characters, especially the ampersand (&). This is due to the DEFINE command, which enables substitution variables. The ampersand is a reserved character for these variables, leading to prompts requesting substitution values. Simple escape methods like backslashes () are ineffective.

The solution is to temporarily disable the DEFINE command. This ensures the ampersand is treated as standard text. Use this command before your SQL statement:

<code class="language-sql">SET DEFINE OFF</code>

With DEFINE OFF, you can directly insert '&' without any escaping or workarounds like CHR(38). This simplifies your queries and prevents interruption.
