org.apache.empire.db.expr.column.DBCalcExpr
This class is used for performing calculations in SQL
It handles the mathematical operations ("+", "-", "*", "/") for the current column.
There is no need to explicitly create instances of this class.
Instead use {@link DBColumnExpr#plus(Object) }, {@link DBColumnExpr#minus(Object) }, {@link DBColumnExpr#multiplyWith(Object) }, {@link DBColumnExpr#divideBy(Object) }
