Why is Visual Code giving me these errors?

The mismatched database in the editor and the unresolved references need separate checks. A SQL project validates a database model, while a query editor also has its own execution connection; the status bar does not by itself prove the project imported the wrong database. First open SQL Server Object Explorer, select the intended server/database, and create a New Query there. Confirm that editor’s connection before executing anything. Then rebuild the project and capture the first complete SQL71501/SQL71502 message from Error List. Check schema-qualified names and any cross-database references or SQLCMD variables named in that message; changing the execution connection alone will not resolve missing model references. Microsoft Learn’s “Debug stored procedures” walkthrough demonstrates a breakpoint on EXEC, Execute With Debugger and F11 to step inside. Use a test database. Share your Visual Studio/SSDT versions and the exact first error so the applicable correction can be identified.
