Class TableSource

java.lang.Object
com.inet.report.TableSource
All Implemented Interfaces:
NodeParser, com.inet.report.ReferenceHolder, Serializable
public class TableSource extends Object implements Serializable, com.inet.report.ReferenceHolder, NodeParser
A TableSource is the representation of a table, a view, a stored procedure or a SQL command. The table description contains of the table name, the alias and the column description. Every datasource will be represented as a single table in the report design. Thereby it is possible to use all tables, stored procedures and SQL statements in one report together. The result of that are multiple requests to the database. Then results of the requests will be joined together by i-net Clear Reports.

Example code:
 Add a table to the report
 
 DatabaseTables dbTables = engine.getDatabaseTables();
 Datasource ds = dbTables.createDatasource("pdssql.dll","localhost","","Northwind","sa","MyPassword");
 //adding a TableSource to the Datasource
 TableSource tabOrderDetails = ds.createTableSource("Order Details");
 tabOrderDetails.addColumn("OrderId",Field.NUMBER);
 tabOrderDetails.addColumn("ProductId",Field.NUMBER);
 tabOrderDetails.addColumn("UnitPrice",Field.NUMBER);
 tabOrderDetails.addColumn("Quantity",Field.NUMBER);
 tabOrderDetails.addColumn("OrderId",Field.NUMBER);
 tabOrderDetails.addColumn("Discount",Field.NUMBER);
 //to receive the DatabaseField of column "OrderId call:
 tabOrderDetails.getDatabaseField(tabOrderDetails.getColumnName(0));

 

 Add a stored procedure to the report:
 
 TableSource sp_salesByYear = ds.createTableSource("Sales By Year");
 //add the result columns to the stored procedure
 sp_salesByYear.addColumn("ShippedDate", Field.DATETIME);
 sp_salesByYear.addColumn("OrderID", Field.NUMBER);
 sp_salesByYear.addColumn("Subtotal", Field.NUMBER);
 sp_salesByYear.addColumn("Year", Field.STRING);

 //define the input parameter of the stored procedure
 String[] inputParamNames =  new String[]{"Beginning_Date","Ending_Date"};
 int[] inputParamTypes =  new int[]{Field.DATETIME,Field.DATETIME};
 sp_salesByYear.setInputParameter(inputParamNames,inputParamTypes);

 

 Add a SQL command to the report:
 
 TableSource cmdOrderDetails = ds.createTableSource("Order Details");
 //Hint: Datasource.createTableSourceCommand(String, String) adds the columns and DatabaseFields automatically.
 cmdOrderDetails.setSql("select * from \"Order Details\" where OrderId = {?OrderId}");
 //add the required PromptField to the report
 cmdOrderDetails.setInputParameter( new String[]{"OrderId"},  new int[]{Field.NUMBER});
 //add the result columns to the sql command
 cmdOrderDetails.addColumn("OrderId",Field.NUMBER);
 cmdOrderDetails.addColumn("ProductId",Field.NUMBER);
 cmdOrderDetails.addColumn("UnitPrice",Field.NUMBER);
 cmdOrderDetails.addColumn("Quantity",Field.NUMBER);
 cmdOrderDetails.addColumn("OrderId",Field.NUMBER);
 cmdOrderDetails.addColumn("Discount",Field.NUMBER);

 


 If the Datasource of the TableSource can create a database Connection, you can use the refresh() to add a table or a stored procedure.
 
      DatabaseTables dbTables = engine.getDatabaseTables();
      Datasource ds = dbTables.createDatasource("pdssql.dll","localhost","","Northwind","sa","MyPassword");
      //adding a TableSource to the Datasource
      TableSource tabOrderDetails = ds.createTableSource("Order Details");
      tabOrderDetails.refresh();//scans the table and adds all columns to TableSource

    • getType

      public int getType() throws ReportException
      Returns the type of that TableSource. Possible are three types. If there is a SQL Statement, the TableSource is from type TYPE_COMMAND. Otherwise it is from type TYPE_PROCEDURE or TYPE_TABLE_OR_VIEW. To find out, which of both it is, the TableSource have to request the DatabaseMetaData. So it is possible to use on one database a view and on an other database instead of the view a stored procedure, if both have same name.

      public boolean isDOMParser()
      FOR INTERNAL USE ONLY Internal method for reading report XML

      Returns whether this node is to be read via a DOM parser.

      Specified by:
      isDOMParser in interface NodeParser

    • parseDOM

      public void parseDOM(Node node, Map<String,Object> parserMap) throws FatalParserException
      FOR INTERNAL USE ONLY Internal method for reading report XML

      Parses the node.

      Specified by:
      parseDOM in interface NodeParser
      Parameters:
      node - the node
      parserMap - The map of current Parser.
      Throws:
      FatalParserException - if an exception occurs which causes the report to not be able to be read: causes the abortion of the reading of the report.

    • parseElement

      public NodeParser parseElement(com.inet.report.parser.XMLTag group, String tag, Attributes atts, Map<String,Object> parserMap) throws FatalParserException
      FOR INTERNAL USE ONLY Internal method for reading report XML

      Parses an XML node with the given information, and returns either a sub-element which was created as a result, or null if no sub-element was created, i.e. the information was applied to the ReportComponent itself. Note that the parsing is highly tolerant, i.e. exceptions are intercepted and suppressed if at all possible.

      Specified by:
      parseElement in interface NodeParser
      Parameters:
      group - XMLTag of the current node to be parsed, or null if there is no such current group. An XMLTag is a group of nodes bundled together, usually it is a Properties node such as CommonProperties, BorderProperties, etc.
      tag - The XMLTag to be parsed
      atts - The set of attributes in the current XMLTag
      parserMap - The map of current Parser.
      Returns:
      The NodeParser sub-element if one needed to be created, or null if none was created.
      Throws:
      FatalParserException - if an exception occurs which causes the report to not be able to be read: causes the abortion of the reading of the report.

    • parseEndElement

      public void parseEndElement(com.inet.report.parser.XMLTag group, String tag, Map<String,Object> parserMap) throws FatalParserException

      Specified by:
      parseEndElement in interface NodeParser
      Parameters:
      group - XMLTag of the current node to be parsed, or null if there is no such current group.
      tag - The XMLTag to be parsed
      parserMap - The map of current Parser.
      Throws:
      FatalParserException - if an exception occurs which causes the report to not be able to be read: causes the abortion of the reading of the report.

    • parseText

      public void parseText(String text, Map<String,Object> parserMap)
      FOR INTERNAL USE ONLY Internal method for reading report XML

      This method is called if text was encountered in the context of this node. (Examples would be a formula's text or a text element's text)

      Specified by:
      parseText in interface NodeParser
      Parameters:
      text - text encountered and to be stored
      parserMap - The map of current Parser.

    • isUsed

      public boolean isUsed() throws ReportException
      Returns the columns of this report are used in the report or this table is used in a join.
