See parent tasks for more context.

In Wikibase client, there are a number of places which build raw SQL expressions rather than use the expression builder. Searching for the terms detailed in the parent task provides the code points seen in the codesearch results. In order top better facilitate separation of concerns in our code, these should be updated to utilize the mediawiki expression builder.

See grandparent task for examples of adoption.

Acceptance Criteria

• No code points in WikibaseClient build raw SQL expressions.
