Why are mutable structs considered dangerous?
Mutable structs are dangerous because structs are copied by value. A developer might think they are modifying the original value, but they may actually be modifying a copy. This can happen when structs are stored in...
Classes, structs, records

Why can MERGE be risky with duplicate source rows?
If multiple source rows match the same target row, a MERGE that updates or deletes the target can become ambiguous because the same target row would be affected more than once. SQL Server can fail the statement in that...
MERGE and upsert patterns, including concurrency cautions
#0221 / INTERMEDIATE / AZURE
How does the OIDC token exchange flow work?
The pipeline requests an OIDC token from its CI/CD provider. The Azure login step or service connection sends that token to Microsoft Entra ID. Microsoft Entra ID validates the token issuer, subject, and audience...
