ColumnModel Class

Definition

Namespace:

System.Data.Entity.Migrations.Model

Assembly:

EntityFramework.dll

Represents information about a column.

Entity Framework Migrations APIs are not designed to accept input provided by untrusted sources (such as the end user of an application). If input is accepted from such sources it should be validated before being passed to these APIs to protect against SQL injection attacks etc.

ColumnModel(PrimitiveTypeKind, TypeUsage)	Initializes a new instance of the ColumnModel class. Entity Framework Migrations APIs are not designed to accept input provided by untrusted sources (such as the end user of an application). If input is accepted from such sources it should be validated before being passed to these APIs to protect against SQL injection attacks etc.

Properties

Annotations	Gets or sets the custom annotations that have changed on the column.
ClrDefaultValue	Gets the default value for the CLR type corresponding to the database type of this column.
ClrType	Gets the CLR type corresponding to the database type of this column.
DefaultValue	Gets or sets a constant value to use as the default value for this property model. Entity Framework Migrations APIs are not designed to accept input provided by untrusted sources (such as the end user of an application). If input is accepted from such sources it should be validated before being passed to these APIs to protect against SQL injection attacks etc. (Inherited from PropertyModel)
DefaultValueSql	Gets or sets a SQL expression used as the default value for this property model. Entity Framework Migrations APIs are not designed to accept input provided by untrusted sources (such as the end user of an application). If input is accepted from such sources it should be validated before being passed to these APIs to protect against SQL injection attacks etc. (Inherited from PropertyModel)
IsFixedLength	Gets or sets a value indicating if this property model is fixed length. Only valid for array data types. (Inherited from PropertyModel)
IsIdentity	Gets or sets a value indicating if values for this column will be generated by the database using the identity pattern.
IsNullable	Gets or sets a value indicating if this column can store null values.
IsTimestamp	Gets or sets a value indicating if this property model should be configured as a timestamp.
IsUnicode	Gets or sets a value indicating if this property model supports Unicode characters. Only valid for textual data types. (Inherited from PropertyModel)
MaxLength	Gets or sets the maximum length for this property model. Only valid for array data types. (Inherited from PropertyModel)
Name	Gets or sets the name of the property model. Entity Framework Migrations APIs are not designed to accept input provided by untrusted sources (such as the end user of an application). If input is accepted from such sources it should be validated before being passed to these APIs to protect against SQL injection attacks etc. (Inherited from PropertyModel)
Precision	Gets or sets the precision for this property model. Only valid for decimal data types. (Inherited from PropertyModel)
Scale	Gets or sets the scale for this property model. Only valid for decimal data types. (Inherited from PropertyModel)
StoreType	Gets or sets a provider specific data type to use for this property model. Entity Framework Migrations APIs are not designed to accept input provided by untrusted sources (such as the end user of an application). If input is accepted from such sources it should be validated before being passed to these APIs to protect against SQL injection attacks etc. (Inherited from PropertyModel)
Type	Gets the data type for this property model. (Inherited from PropertyModel)
TypeUsage	Gets additional details about the data type of this property model. This includes details such as maximum length, nullability etc. (Inherited from PropertyModel)

Methods

IsNarrowerThan(ColumnModel, DbProviderManifest)

Determines if this column is a narrower data type than another column. Used to determine if altering the supplied column definition to this definition will result in data loss.
