如果是单纯的在dos下连接sql70应该没有什么意义!如果在dos下写程序可能用delphi2可以吧!
Microsoft® SQL Server™ version 7.0 does not supply the environment for compiling ESQL/C 16-bit Microsoft MS-DOS® clients (the 16-bit binaries for MS-DOS are not included). However, these clients will run under SQL Server 7.0. To compile an ESQL/C 16-bit MS-DOS client, you need to use the ESQL/C compilation environment in SQL Server 6.0 or 6.5, which includes the 16-bit MS-DOS binaries.
