Supported Data Types

The c-treeACE SQL JDBC Driver supports standard JDBC mapping of JDBC types to corresponding Java types.

In the JDBC methods CallableStatement.get..XXX() and PreparedStatement.set...XXX() methods, XXX is a Java type:

For ...setXXX() methods, the driver converts the Java type to the c-treeACE SQL JDBC type shown in the following table before sending it to the database.
For ...getXXX() methods, the driver converts the c-treeACE SQL JDBC type returned by the database to the Java type shown in “Mapping Between JDBC and Java Data Types” before returning it to the ...getXXX() method.

Mapping Between Java and JDBC Data Types

Java Type	JDBC type	Java Type	JDBC type
String	VARCHAR or LONGVARCHAR	float	REAL
java.math.BigDecimal	NUMERIC	double	DOUBLE
boolean	BIT	byte[]	VARBINARY or LONGVARBINARY
byte	TINYINT	java.sql.Date	DATE
short	SMALLINT	java.sql.Time	TIME
int	INTEGER	java.sql.Timestamp	TIMESTAMP
long	BIGINT
