Base Query to Reset/Set a Field

I have a table that contains text fields. I can make a query to select the desired records with standard query syntax. I am now looking for a way to set those fields to a specific value.

Example: Change a field called Y5 from a value of ABC to XYZ

I can do this manually (and slowly) using a form entry but would like to find a way to do it via a query.

Any suggestions would be appreciated.

It makes SQL-command

UPDATE "Test" SET Y5='XYZ' WHERE Y5='ABC'

How to: Change a field called Y5 from a value of ABC to XYZ

I guess I need to go through some SQL tutorials and learn the language and syntax. Previously (a long time ago) used Paradox and as I recall these kinds of commands were mostly built in to the query structure with a relatively simple UI.

Thanks so much for the great visual. That really helps!!
