Techniques are provided for selectively or completely redacting the text of database commands submitted to a database system. The database server receives the clear text version of the commands, parses the commands, and generates an execution plan, as normal. However, prior to providing the text of the commands to any location that is externally visible, the database server determines whether the command qualifies as 'sensitive'. If the command qualifies as sensitive, then a redacted version of the command is generated. In the case of selective redaction, portions of the redacted version remain in clear text, while selected portions are replaced with encrypted text. In the case of total redaction, the entire command is replaced with encrypted text.
