Uses of DBCommandExpr in org.apache.empire.db
 

Subclasses of DBCommandExpr in org.apache.empire.db
 class DBCombinedCmd
          This class is used for building up a partition of a SQL-Command.
 class DBCommand
          This abstract class handles the creation of the SQL-Commands.
 

Fields in org.apache.empire.db declared as DBCommandExpr
protected  DBCommandExpr DBQuery.cmdExpr
           
protected  DBCommandExpr DBCombinedCmd.left
           
protected  DBCommandExpr DBCombinedCmd.right
           
 

Methods in org.apache.empire.db that return DBCommandExpr
 DBCommandExpr DBDatabaseDriver.createCombinedCommand(DBCommandExpr left, String keyWord, DBCommandExpr right)
          This function gives the driver a chance to provide a custom implementation for a combined command such as UNION or INTERSECT
abstract  DBCommandExpr DBView.createCommand()
          Returns the command required to create the view
This is function is only used for the creation of DDL statements
 DBCommandExpr DBQuery.getCommandExpr()
          returns the underlying command expression
 DBCommandExpr DBCommandExpr.intersect(DBCommandExpr other)
          Constructs a new DBCombinedCmd object with this object, the key word= "INTERSECT" and the selected DBCommandExpr.
 DBCommandExpr DBCommandExpr.union(DBCommandExpr other)
          Constructs a new DBCombinedCmd object with this object, the key word= "UNION" and the selected DBCommandExpr.
 

Methods in org.apache.empire.db with parameters of type DBCommandExpr
 DBCommandExpr DBDatabaseDriver.createCombinedCommand(DBCommandExpr left, String keyWord, DBCommandExpr right)
          This function gives the driver a chance to provide a custom implementation for a combined command such as UNION or INTERSECT
 void DBReader.getRecordData(DBCommandExpr cmd, Connection conn)
           Opens the reader by executing the given SQL command and moves to the first row.
If true is returned data of the row can be accessed through the functions on the RecordData interface.
This function is intended for single row queries and provided for convenience.
However it behaves exacly as calling reader.open() and reader.moveNext()
 DBCommandExpr DBCommandExpr.intersect(DBCommandExpr other)
          Constructs a new DBCombinedCmd object with this object, the key word= "INTERSECT" and the selected DBCommandExpr.
 void DBReader.open(DBCommandExpr cmd, boolean scrollable, Connection conn)
          Opens the reader by executing the given SQL command.
After the reader is open, the reader's position is before the first record.
Use moveNext or iterator() to step through the rows.
Data of the current row can be accessed through the functions on the RecordData interface.
 void DBReader.open(DBCommandExpr cmd, Connection conn)
          Opens the reader by executing the given SQL command.
 DBCommandExpr DBCommandExpr.union(DBCommandExpr other)
          Constructs a new DBCombinedCmd object with this object, the key word= "UNION" and the selected DBCommandExpr.
 

Constructors in org.apache.empire.db with parameters of type DBCommandExpr
DBCombinedCmd(DBCommandExpr left, String keyWord, DBCommandExpr right)
          Constructs a new DBFuncExpr object and sets the specified parameters to this object.
DBCommandExpr.DBCmdQuery(DBCommandExpr cmd, DBColumnExpr[] colList)
          Creates a new DBCmdQueryObject
DBQuery(DBCommandExpr cmd)
          Creaes a DBQuery object from a given command object.
DBQuery(DBCommandExpr cmd, DBColumn keyColumn)
          Constructs a new DBQuery object initialize the query object.
DBQuery(DBCommandExpr cmd, DBColumn[] keyColumns)
          Constructor initializes the query object.
