Creating a table object without database support

It is possible to create or open a table without database support by passing a session object when creating the table object. Start your session with the CTSESSION_CTREE mode.

// create the session and table objects

CTSession ASession(CTSESSION_CTREE);

CTTable ATable(ASession);

// logon to session

ASession.Logon(“FAIRCOMS”, “ADMIN”, “ADMIN”);

// without database support, it is necessary to

// specify the path were the table is located

ATable.SetPath(“C:\\MyDocuments”);

// open the table

try

{

   ATable.Open(“MyTable”, CTOPEN_NORMAL);

}

catch (CTException &err)

{

   printf(“Table open failed with error %d\n, err.GetErrorCode());

}

Please note from the code above the need to specify the path where the table is located. If no path is specified, c-treeDB will try to open the table from the current directory. The same principle applies when creating a table without database support:

// create the session and table objects

CTSession ASession(CTSESSION_CTREE);

CTTable ATable(ASession);

// logon to session

ASession.Logon(“FAIRCOMS”, “ADMIN”, “ADMIN”);

// add fields to table

ATable.AddField(“Field1”, CT_INT2, 2);

ATable.AddField(“Field2”, CT_FSTRING, 30);

// without database support, it is necessary to

// specify the path were the table is located

ATable.SetPath(“C:\\MyDocuments”);

// open the table

try

{

   ATable.Create(“MyTable”, CTCREATE_NORMAL);

}

catch (CTException &err)

{

   printf(“Create open failed with error %d\n, err.GetErrorCode());

}
