How are JDBC types mapped to DataSet Column types

阅读更多
The JDBC to DataSet type mapping is pretty much the same as the JDBC to Java type mapping:
JDBC Types DataSet Types
java.sql.Types.LONGVARCHAR

java.sql.Types.CHAR

java.sql.Types.VARCHAR

Oracle ROWID is a String:

Variant.STRING
java.sql.Types.NUMERIC

java.sql.Types.DECIMAL

Variant.BIGDECIMAL
java.sql.Types.BIT Variant.BOOLEAN
java.sql.Types.TINYINT Variant.BYTE
java.sql.Types.SMALLINT Variant.SHORT
java.sql.Types.INTEGER Variant.INT
java.sql.Types.BIGINT Variant.LONG
java.sql.Types.REAL Variant.FLOAT
java.sql.Types.FLOAT

java.sql.Types.DOUBLE

Variant.DOUBLE
java.sql.Types.VARBINARY

java.sql.Types.LONGVARBINARY

java.sql.Types.BINARY

Variant.INPUTSTREAM
java.sql.Types.DATE Variant.DATE
java.sql.Types.TIME Variant.TIME
java.sql.Types.TIMESTAMP Variant.TIMESTAMP
java.sql.Types.OTHER Variant.OBJECT
