Method Detail

getDataType

public DataType getDataType(int jdbcType,
                   String name,
                   int size)

Description copied from interface: Vendor

Returns a DataType corresponding to a JDBC type. This may be an unsupported datatype; in this case, its DataType.isUnsupported() method will return true. null will be returned if the vendor code doesn't handle this datatype at all; that should generally be considered a bug.

Specified by:

getDataType in interface Vendor

Overrides:

getDataType in class SQL92

Parameters:

jdbcType - A java.sql.Types constant

name - The type name, as reported by java.sql metadata methods, normalized to uppercase

size - Character size of the type, or 0 if not applicable

Returns:

A compatible D2RQ DataType instance, or null if the vendor code is broken

initializeConnection

public void initializeConnection(Connection connection)
                          throws SQLException

Description copied from interface: Vendor

Vendor-specific initialization for a database connection.

Specified by:

initializeConnection in interface Vendor

Overrides:

initializeConnection in class SQL92

Throws:

SQLException
