Methods
| EscapeLikeArgument(String) |
Provider writers should override this method to return the argument with the wildcards and the escape character escaped. This method is only used if SupportsEscapingLikeArgument returns true. |
| GetDbInformation(String) |
When overridden in a derived class, this method returns provider-specific information. |
| GetEdmType(TypeUsage) |
When overridden in a derived class, this method maps the specified storage type and a set of facets for that type to an EDM type. |
| GetFacetDescriptions(EdmType) |
Returns the FacetDescription objects for a particular type. |
| GetInformation(String) |
Gets the provider-specific information. |
| GetStoreFunctions() |
When overridden in a derived class, returns a collection of EDM functions supported by the provider manifest. |
| GetStoreType(TypeUsage) |
When overridden in a derived class, this method maps the specified EDM type and a set of facets for that type to a storage type. |
| GetStoreTypes() |
When overridden in a derived class, returns the set of primitive types supported by the data source. |
| SupportsEscapingLikeArgument(Char) |
Indicates if the provider supports escaping strings to be used as patterns in a Like expression. |
| SupportsInExpression() |
Returns a boolean that specifies whether the provider can handle expression trees
containing instances of DbInExpression.
The default implementation returns |
| SupportsIntersectAndUnionAllFlattening() |
Returns a boolean that specifies whether the provider can process expression trees not having DbProjectExpression nodes directly under both Left and Right sides of DbUnionAllExpression and DbIntersectExpression |
| SupportsParameterOptimizationInSchemaQueries() |
Indicates if the provider supports the parameter optimization described in EntityFramework6 GitHub issue #195.
