A reserved keyword is a word that has a special meaning, and is therefore “reserved from use.” Reserved keywords are also known as reserved identifiers.

In this guide, we’ll cover:


Reserved keyword basics

What's a reserved keyword?

A reserved keyword is a word that has a special meaning, and is therefore “reserved from use.” Reserved keywords are also known as reserved identifiers.

In Stitch, there are two types of reserved keywords:

  • Stitch reserved keywords, or words that are reserved to Stitch. For example: The _sdc prefix used in Stitch system tables and columns.
  • Destination reserved keywords, or words that are reserved by a destination.

Why can't I use reserved keywords?

Stitch reserves its own keywords to ensure your data is loaded accurately. Additionally, each destination has its own list of reserved keywords and its own reasons for reserving those words.

Refer to the Keyword reference section for info about the keywords reserved for each destination.

What happens to data that contains reserved keywords?

If a table or column contains a reserved keyword, the destination will reject the data and create a record in the rejected records log.

An error will also surface in the Notifications tab in Stitch.


Reserved keyword reference

In this section are the reserved keywords for each destination supported by Stitch.

Note: Keywords are case-insensitive. This means that ABC, aBc, abc, etc. are all considered the same.
