operator long

Applies To
OField

Description
This method returns the object's value as a long.

Usage
operator long() const

Remarks
This method hands the value of the object back to the caller as a long. If the object's current value is not a long, the method attempts to convert the value. This can fail, resulting in the return of the value 0.

Return Value
The value of the field as a long; 0 on failure.

Example
Look for the employee with a certain employee ID:

// open the ODatabase

ODatabase odb("ExampleDB", "scott", "tiger")

// open the dynaset

ODynaset odyn(odb, "select * from emp");

// get a field on the id

OField enof = odyn.GetField("empno");

// now look for the id we want

while (!odyn.IsEOF())

{

// we'll examine the value of the id field in this record simply

// by casting the enof OField variable

if ((long) enof == targetid)

break;

}
