/**export Text(comma separated,or pipe separated, or tab separated) file data to Oracle database
 *@param sourceUrl assign the text file directory location, in fact, you can assign any legal jdbc url not contains the prefix part(jdbc:text:/, or jdbc:csv:/), so, c:/tmp,  c:/tmp/xx.zip, ////192.168.10.2/sharedir, //domain.com:3099/c:/data all can assigned to this parameter,  more about this information, please see the document
 *@param sourceTableName assign the source table name
 *@param targetSchemaName assign the destination schema, it null, export to the current schema
 *@param targetTableName assign the destination table name which you want to exported to it
 *@param sourceConnPar  assign the conntion properties, please split multi properties by ';' ,for example, username=abc;password=abc
 */
 public static void exportTable(String sourceUrl, String sourceTableName, String targetSchemaName, String targetTableName,String sourceConnPar)
 
 
/**export SQL query result to Oracle database
 *@param sourceUrl assign the text file directory location,in fact, you can assign any legal jdbc url not contains the prefix part(jdbc:text:/, or jdbc:csv:/), so, c:/tmp,  c:/tmp/xx.zip, ////192.168.10.2/sharedir, //domain.com:3099/c:/data all can assigned to this parameter,  more about this information, please see the document
 *@param querySQL assign the query SQL
 *@param targetSchemaName assign the destination schema, it null, export to the current schema
 *@param targetTableName assign the destination table name which you want to exported to it
 *@param sourceConnPar  assign the conntion properties, please split multi properties by ';' ,for example, username=abc;password=abc
 */
 public static void exportQuery(String sourceUrl, String query, String targetSchemaName, String targetTableName, String sourceConnPar)
 
 
You should supply a Oracle 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, this code execute two operations.

com.hxtt.data.export.advance.ConnectionGetter.setConnection(yourConnection);
com.hxtt.data.export.advance.Text2Oracle.exportTable("c:/tmp","ATABLE",null,"BTABLE",null);


com.hxtt.data.export.advance.ConnectionGetter.setConnection(yourConnection);
com.hxtt.data.export.advance.Text2Oracle.exportQuery("c:/tmp","select * from atable a, btable b where a.id=b.id",null,"BTABLE",null);
