Description
CTTable::Attach() attaches a c-tree Plus ISAM datno object to a c-treeDB table object. This function is useful if you have opened a data and index file using one of c-tree’s ISAM open functions and need to attach it to a table handle to use some of the advanced c-treeDB features such as alter table or the record handler.
Return
void
Example
CTSession hSession(CTSESSION_CTREE);
CTTable hTable(hSession);
CTRecord hRecord(hTable);
NINT datno, count = 0;
// logon to c-tree
hSession.Logon(SERVER, USER, PASSWD);
// open the file using c-tree ISAM
datno = (NINT)OPNRFILX((COUNT) -1, "test309.dat", (COUNT)0, NULL);)
// attach to table
hTable.Attach(datno);
// read the records
if (hRecord.First())
do
{
count++;
}
while (hRecord.Next());
// cleanup
hTable.Detach();
hSession.Logout();
