public sealed class ArxColumnDefinition

Constructor

• ArxColumnDefinition(string name, Type type, string databaseType, bool isNullable, ArxColumnTraits traits = ArxColumnTraits.None)

  A column definition, as a preload creates it (or by hand, for a table a preload can't read).

  Parameter	Type	Description
  name	string	The column name.
  type	Type	The .NET type ARX reads the column as.
  databaseType	string	The database's type name (for an array, its element type).
  isNullable	bool	Whether the column accepts NULL.
  traits	ArxColumnTraits= ArxColumnTraits.None	What the database type is beyond its .NET type: an enum, a composite, an array, JSON, a default.

Properties

• string Name { get; }

  The column name.

• Type Type { get; }

  The .NET type values of this column read back as (Retrieve's value mapping), and are expected as.

• string DatabaseType { get; }

  The database's type name, as it names it (for example int8 or varchar in PostgreSQL, nvarchar in SQL Server; for an array, its element's).

• bool IsNullable { get; }

  Whether the column accepts NULL.

• ArxColumnTraits Traits { get; }

  What the database type is beyond its .NET type: an enum, a composite, an array, JSON, a column with a default.
