I have just started using LO Base 3.4.4.  I created 2 tables with a
relationship between them.  I then deleted one of the tables and created
another one with a relationship to the first.  When I try to add records to
the table is gives me the following error message: "SQL Status: 23000
Error code: -177

Integrity constraint violation - no parent SYS_FK_110 table:  Patient Old in
statement [INSERT INTO "Pharm Rcpt" (
"pr_Cost","pr_Date","pr_Doctor","pr_Med","pr_Patient","pr_Pharm","pr_Qty")
VALUES ( ?,?,?,?,?,?,?)]"

It looks like the relationship did not get deleted when the table was
deleted.

You never define a relationship in Base. You always do that in a database software even when you are working with the built-in database engine (status bar reads: "embedded HSQLDB"), this "integrated" database behaves exactly like any external database such as MySQL and many others. The self explaining error message comes from that database software and it says that you try to enter a patient-ID that has no counterpart in the patient table's primary key.

Base can help you to avoid all integrity constraint errors by means of subforms and list boxes which are the 2 key elements to edit relational data in Base forms.

[Example] Relations reflected by list boxes in forms:
