DbType

Each instance of this class or its descendant represent a base data type supported by a DBMS: such as CHAR, DATE etc.

Storage options (such as VARCHAR's length, DECIMAL precision etc.) are not reflected here: they are properties of individual DbColumns.

Properties

• DbTypeArithmetic
  • DbTypeArithmeticFixed
  • DbTypeArithmeticFloat
  • DbTypeArithmeticInt
• DbTypeCharacter
• DbTypeTemporal
  • DbTypeDate
  • DbTypeTimestamp
