tsql - Sybase: 'go' block 中 'IF EXISTS' 附近的语法不正确

Question

这是我的 sql 语句

IF EXISTS (select 1 from sysobjects where name = 'PNL_VALUE_ESTIMATE')
  drop table dbo.PNL_VALUE_ESTIMATE
go

isql 退出此错误消息

Msg 102, Level 15, State 1:
Server 'DB_SERVER', Line 3:
Incorrect syntax near 'go'.

但是 sql 语句对我来说是正确的。怎么了？

Sybase 版本是 15

尝试这个:

IF EXISTS (select 1 from sysobjects where name = 'PNL_VALUE_ESTIMATE')
  drop table dbo.PNL_VALUE_ESTIMATE

go

或这个:

IF EXISTS (select 1 from sysobjects where name = 'PNL_VALUE_ESTIMATE')
BEGIN
  drop table dbo.PNL_VALUE_ESTIMATE
END

go

或这个:

IF EXISTS (select 1 from sysobjects where name = 'PNL_VALUE_ESTIMATE')
BEGIN
  select 1
END

go

有没有用？
