HasComputedColumnSql(PrimitiveCollectionBuilder)
Configures the property to map to a computed column when targeting a relational database.
public static Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder HasComputedColumnSql (this Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder primitiveCollectionBuilder);static member HasComputedColumnSql : Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder -> Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder<Extension()>
Public Function HasComputedColumnSql (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 arguments, this method tells EF that a column is computed without needing to specify the actual SQL used to computed it. This can be useful when mapping EF to an existing database.
See Database default values for more information and examples.
Applies to
HasComputedColumnSql(PrimitiveCollectionBuilder, String)
Configures the property to map to a computed column when targeting a relational database.
public static Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder HasComputedColumnSql (this Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder primitiveCollectionBuilder, string? sql);static member HasComputedColumnSql : Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder * string -> Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder<Extension()>
Public Function HasComputedColumnSql (primitiveCollectionBuilder As PrimitiveCollectionBuilder, sql As String) As PrimitiveCollectionBuilderParameters
- primitiveCollectionBuilder
- PrimitiveCollectionBuilder
The builder for the property being configured.
- sql
- String
The SQL expression that computes values for the column.
Returns

Applies to
HasComputedColumnSql(PrimitiveCollectionBuilder, String, Nullable<Boolean>)
Configures the property to map to a computed column when targeting a relational database.
public static Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder HasComputedColumnSql (this Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder primitiveCollectionBuilder, string? sql, bool? stored);static member HasComputedColumnSql : Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder * string * Nullable<bool> -> Microsoft.EntityFrameworkCore.Metadata.Builders.PrimitiveCollectionBuilder<Extension()>
Public Function HasComputedColumnSql (primitiveCollectionBuilder As PrimitiveCollectionBuilder, sql As String, stored As Nullable(Of Boolean)) As PrimitiveCollectionBuilderParameters
- primitiveCollectionBuilder
- PrimitiveCollectionBuilder
The builder for the property being configured.
- sql
- String
The SQL expression that computes values for the column.
If true, the computed value is calculated on row modification and stored in the database like a regular column.
If false, the value is computed when the value is read, and does not occupy any actual storage.
null selects the database provider default.
Returns
The same builder instance so that multiple calls can be chained.
Remarks
