com.hxtt.data.export.advance.DBF2DB2.exportTable("c:/tmp","ATABLE",null,"BTABLE",null);


You just supply a DB2 database connection , and then call the method. We will release this connection after complete a export operation for we want to avoid holding a reference to the connection . So, if you want continue execute other export operation, you should recall the setConnection method, for example, the code follows export two table to the target.

com.hxtt.data.export.advance.ConnectionGetter.setConnection(yourConnection);
com.hxtt.data.export.advance.DBF2DB2.exportQuery("c:/tmp","select * from atable a, btable b where a.id=b.id",null,"BTABLE",null);
