public class Types
extends Object

The class that defines constants that are used to identify generic SQL types, called JDBC types. The actual type constant values are equivalent to those in XOPEN.

Field Summary

static int ARRAY
          JDBC 2.0 A type representing an SQL ARRAY.

static int BIGINT


static int BINARY


static int BIT


static int BLOB
          JDBC 2.0 A type representing an SQL Binary Large Object.

static int CHAR


static int CLOB
          JDBC 2.0 A type representing an SQL Character Large Object.

static int DATE


static int DECIMAL


static int DISTINCT
          JDBC 2.0 A type based on a built-in type.

static int DOUBLE


static int FLOAT


static int INTEGER


static int JAVA_OBJECT
          JDBC 2.0 A type representing a Java Object.

static int LONGVARBINARY


static int LONGVARCHAR


static int NULL


static int NUMERIC


static int OTHER
          OTHER indicates that the SQL type is database-specific and gets mapped to a Java object that can be accessed via the methods getObject and setObject.

static int REAL


static int REF
          JDBC 2.0 A type representing an SQL REF.

static int SMALLINT


static int STRUCT
          JDBC 2.0 A type consisting of attributes that may be any type.

static int TIME


static int TIMESTAMP


static int TINYINT


static int VARBINARY


static int VARCHAR
