public class DBCalcExpr extends DBColumnExpr
There is no need to explicitly create instances of this class.
Instead use DBColumnExpr.plus(Object), DBColumnExpr.minus(Object),
DBColumnExpr.multiplyWith(Object), DBColumnExpr.divideBy(Object)

DBCalcExpr(DBColumnExpr expr,
String op,
Object value)
Constructs a DBCalcExpr object Sets the mathematical operations ("+", "-", "*", "/")
for the specified DBColumnExpr object and value. |
| Modifier and Type | Method and Description |
|---|---|
void |
addReferencedColumns(Set<DBColumn> list)
Internal function to obtain all DBColumnExpr-objects used by this expression.
|
void |
addSQL(DBSQLBuilder sql,
long context)
Creates the SQL-Command adds the mathematical operations for
the specified DBColumnExpr object and value to the.
|
Element |
addXml(Element parent,
long flags)
This function set the specified mathematical operations to the XML tag.
|
boolean |
equals(Object other)
Returns true if other is equal to this expression
|
DBDatabase |
getDatabase()
Returns the current DBDatabase object.
|
DataType |
getDataType()
Returns the data type: DBDataType.DECIMAL.

getName()
Returns the given expression name.
|
DBRowSet |
getRowSet()
Returns the underlying rowset
|
DBColumn |
getUpdateColumn()
Returns the underlying column
|
boolean |
