IsEOF Method

Applies To
ODynaset

Description
This routine returns TRUE if the current record is after the last record in the result set.

Usage
oboolean IsEOF(void) const

Remarks
This method returns TRUE if the current record is after the last record of the dynaset result set. This can happen if the MoveNext method is executed at the time that the last record is current, if the current record is the last record and it is deleted, or if there are no records in the result set.

The name means "End of File" and is a relic from flat-file databases.

Return Value
TRUE if (1) the current record is after the last record (2) the ODynaset is closed or (3) the dynaset has no records; FALSE otherwise.

Example
This example deletes all the managers.

// open a database

ODatabase odb("ExampleDB", "scott/tiger", 0);

// open a dynaset

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

// get an OField object for looking at the job field

OField job = empdyn.GetField("job");

// look through all the employees

while (!empdyn.IsEOF())

{

if (0 == strcmp((const char *) job, "MANAGER"))

{ // we found a manager - delete that employee
