Cincom ORDB JDBC extension typesAlthough Cincom ORDB extensions are summarized here, see "4.Cincom ORDB Extensions" on page 28 for additional information.In addition, SQL datatypes also support the summarized JDBC extensions belowand shows their mappings to Cincom ORDB datatypes:♦♦♦The SQL datatype column lists the SQL datatypes that exist in thedatabase.The JDBC extensions for SQL datatypes column lists the types into whichCincom ORDB datatypes should map according to the JDBC 3.0 standard.The Cincom ORDB extensions—Java classes that represent SQL Datatypescolumn lists the ordbjava.jdbc.* Java types that correspond to each SQLdatatype in the database and that let you use the special features of theCincom ORDB database objects.SQL datatypeObject ReferenceJDBC extensionsfor SQL datatypesjava.sql.RefCincom ORDB extensions—Java classesthat represent SQL datatypes♦♦ordbjava.jdbc.ordbGlo if thereference is for an instance of a glo, ora subclass of glo.ordbjava.jdbc.ordbObject if thereference is for an instance that is nota glo.Object Referencejava.sql.Struct♦ordbjava.jdbc.ordbGlo if thereference is for an instance of a glo, ora subclass of glo.♦ordbjava.jdbc.ordbObject if thereference is for an instance that is nota glo.Object Reference (GLO) java.sql.Blob ordbjava.jdbc.ordbGloObject Reference (GLO) java.sql.Clob ordbjava.jdbc.ordbGloCollections (sets, multisets,and sequences)java.sql.Array ordbjava.jdbc.ordbCollectionJDBC Developer's Guide, P25-9504-03 Page 26Chapter: 3.

Error Messages and JDBCTo handle exceptions, the Cincom ORDB JDBC driver throws ajava.sql.SQLException() for both database and JDBC Driver errors. Theexception object contains a text message describing the error.You can display the error messages with these methods:♦♦getMessage() — Returns the error message associated with the objectthat threw the exceptionprintStackTrace() — Prints this object name and its StackTrace to thespecified print streamThe following example uses both the getMessage() method and theprintStackTrace() method to return errors:catch(SQLException e);{System.out.println("exception: " + e.getMessage());e.printStackTrace();}The text of all error messages is internationalized. That is, they areavailable in all of the languages and character sets supported byCincom ORDB. For a list of these error messages, refer to the CincomBIfor SUPRA Messages and Codes, P25-9502.JDBC Developer's Guide, P25-9504-03 Page 27Chapter: 3. Basic FeaturesSection: Error Messages and JDBC
