class DataType

[source: scala/dbc/DataType.scala]

abstract class DataType
extends AnyRef
An ISO-9075:2003 (SQL) data type. Mappings between SQL types and database specific types should be provided by the database driver.
Direct Known Subclasses:
Boolean, Numeric, String, Unknown

Type Summary
abstract type NativeType
The native Scala type in which values of this SQL type will be encoded.
Method Summary
abstract def isEquivalent (datatype : DataType) : Boolean
Tests whether this datatype is equivalent to another. Usually, two types are defined as equivalent if they are equal. Two types can be equivalent without being equal if values of those types will be encoded in the same native Scala type.
abstract def isSubtypeOf (datatype : DataType) : Boolean
Tests whether this datatype is equivalent or a subtype of another datatype. Type A is said to be subtype of type B if any value of type A can be represented as a value of type B.
abstract def nativeTypeId : Int
The native Scala type in which values of this SQL type will be encoded. This must point to the same type as NativeType.
def nullable : Option[Boolean]
Whether the value can take the null value, None when this property is unknown.
def sqlString : String
The SQL name of the type
