Oracle SQL: How to Avoid Substitution Variable Prompts for '&' in INSERT Statements?

Oracle SQL: Handling Ampersand (&) Substitution Variables

When constructing SQL INSERT statements in Oracle SQL Developer, you might encounter prompts requesting substitution values. This typically happens when your query includes special characters like the ampersand (&). Simply escaping the ampersand with a backslash (&) doesn't resolve the problem; Oracle still interprets it as a substitution variable.

The most effective solution is to use the SET DEFINE OFF command. This command disables Oracle's automatic substitution variable feature, preventing the ampersand from triggering the substitution prompt. This eliminates the need for escaping or using alternative representations like CHR(38).
