Overview

Implements Int64 value type OID support.

Usage:

Optional: Assign the TIOPFManager's Default OID Generator property like this: GTIOPFManager.DefaultOIDGenerator := TtiOIDGeneratorInt64.Create;
Required: Make sure you have a Next_OID table with an OID field of type Integer. eg: CREATE TABLE NEXT_OID ( OID INTEGER NOT NULL, CONSTRAINT PK_NEXT_OID PRIMARY KEY (OID) );
Required: Make sure you have an initial record inserted into the Next_OID table, and set the starting high value for the generator. eg: INSERT INTO NEXT_OID VALUES (1);

Remark:

You can't set the seed value to 0 (constant values cNullOIDInteger) because that is treated as a NULL value. eg: if MyOID.IsNull() then ...
