Hello!

The error message you're receiving, "UsrSalesInfo violates foreign key constraints," indicates that there is a problem with a foreign key constraint in your database. Foreign key constraints are rules that enforce referential integrity between tables.

The code "FKEJfjpa4vcAfSKimC9hWFxF6Gxm8" you mentioned is a reference to the specific foreign key constraint that's causing the error. It's an automatically generated name for the constraint, commonly used by database management systems.

To find out which table is affected by the foreign key constraint violation, you can query the system tables or views provided by your database management system.

An example of a possible script for this task: 

SELECT

    name,

    OBJECT_NAME(parent_object_id) AS referencing_table,

    OBJECT_NAME(referenced_object_id) AS referenced_table

FROM

    sys.foreign_keys

WHERE

    name = 'FKEJfjpa4vcAfSKimC9hWFxF6Gxm8';

 

Hope this helps!
