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. |
