♦writeSQL() method. You must implement writeSQL() as follows:public void writeSQL(SQLOutput stream) throws SQLException- writeSQL() must take as input an SQLOutput stream.- When your Java application calls writeSQL(), the JDBC driver creates anSQLOutput stream object and populates it with data from your customJava class. When the driver calls writeSQL(), it passes in this streamparameter.- For each Java datatype that maps to an attribute of the Cincom ORDBclass, writeSQL() must call the appropriate writeXXX() method of theSQLOutput stream that is passed in.- For example, if you are writing to objects that have a CHAR attributefollowed by an INTEGER attribute, then you must have a writeString()call and a writeInt() call in your writeSQL() method. These methodsmust be called according to the order that attributes appear in theschema definition of the Cincom ORDB class.- writeSQL() must then write the data converted by the writeXXX()methods to the SQLOutput stream so it can be written to the databaseonce you execute the prepared statement.JDBC Developer's Guide, P25-9504-03 Page 60Chapter: 4.

Working with Cincom ORDB collectionsThe Cincom ORDB JDBC Driver exposes database collections as instances of theclass ordbjava.jdbc.ordbCollection. The ordbCollection class implements thejava.sql.Array interface, and provides additional methods to make it easier towork with Cincom ORDB collections.The following sections discuss how to:♦ Retrieve a collection and its elements♦♦♦♦Work with heterogeneous collectionsHomogeneous collections and Java primitive arraysCreate and modify collectionsCollections and custom mapping♦ Freeing Cincom ORDB workspace storage used by ordbCollectionsThe Cincom ORDB JDBC Driver exposes database collections as instances of theclass ordbjava.jdbc.ordbCollection. The ordbCollection class implements thejava.sql.Array interface, and provides additional methods to make it easier towork with Cincom ORDB collections.JDBC Developer's Guide, P25-9504-03 Page 61Chapter: 4.
