Namespace LinqToDB.Internal.DataProvider
Classes
- DmlServiceBase
Base class for provider-specific IDmlService implementations. Only providers whose DROP TABLE cannot express "if exists" at the SQL level register one — for every other provider the service is absent and suppression is not attempted.
- NoopQueryParametersNormalizer
No-op query parameter normalization policy. Could be used for providers with positional nameless parameters or providers without database support.
- UniqueParametersNormalizer
Parameter name rules, implemented by this policy:
- duplicate name check is case-insensitive
- max name length: 50 characters
- allowed characters: ASCII digits, ASCII letters, _ (underscore).
- allowed first character: ASCII letter.
- default name if name missing/invalid: "p"
- duplicates resolved by adding "_counter" suffix
Structs
Interfaces
- IDmlService
Provider-specific DML mechanics that can't be expressed through SQL generation alone. Resolved from the data context's service provider by query runners that execute DML.
- IDynamicProviderAdapter
Contains base information about ADO.NET provider. Could be extended by specific implementation to expose additional provider-specific services.
- IQueryParametersNormalizer
Interface, implemented by query parameter name normalization policy for specific provider/database.
