HasDefaultValueSql(PrimitiveCollectionBuilder)
Configures the default value expression for the column that the property maps to when targeting a relational database.
public static Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder HasDefaultValueSql (this Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder primitiveCollectionBuilder);static member HasDefaultValueSql : Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder -> Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder<Extension()>
Public Function HasDefaultValueSql (primitiveCollectionBuilder As PrimitiveCollectionBuilder) As PrimitiveCollectionBuilderParameters
- primitiveCollectionBuilder
- PrimitiveCollectionBuilder
The builder for the property being configured.
Returns
The same builder instance so that multiple calls can be chained.
Remarks
When called with no argument, this method tells EF that a column has a default value constraint of some sort without needing to specify exactly what it is. This can be useful when mapping EF to an existing database.
See Database default values for more information and examples.
