The SyncSchemaColumn type exposes the following members.

Properties

	Name	Description
	AllowNull	Gets or sets a value that indicates whether null values are allowed in this column.
	AutoIncrement	Gets or sets a value indicating whether the column automatically increments its value when new rows are inserted into the table.
	AutoIncrementSeed	Gets or sets the starting value for a column that has its AutoIncrement property set to true.
	AutoIncrementStep	Gets or sets the increment for a column that has its AutoIncrement property set to true.
	Collation	Gets or sets the collation for the column. Collation is a set of rules that determines how data is compared, ordered, and presented.
	ColumnName	Gets or sets the name of the column.
	DataType	Gets or sets a Type object that represents the type of data stored in the column.
	DefaultValue	Gets or sets the default value for the column when new rows are created.
	MaxLength	Gets or sets the maximum length of a text column.
	NumericPrecision	Gets of sets the numeric precision for the column if the data type is Decimal.

Remarks

The column is the fundamental building block for creating the schema of a table. Build the schema by adding one or more column objects to the column list. Each column has a DataType property that determines the kind of data that the column contains. For example, you can restrict the data type to integers, or strings, or decimals in the form of .NET Framework types. Each column also has a ProviderDataType property that determines the SQL Server data type of the column. A column object always depends on the table that contains this column.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
