    Unanswered: Declaring variables for later use


    This works

    isql> declare @i int
    isql> select @i = 1
    isql> go
    (1 row affected)

    But this doesn't

    isql> declare @i int
    isql> go
    isql> select @i = 1
    isql> go
    Msg 137, Level 15, State 1:
    Server 'DSGPCPOET01', Line 1:
    Must declare variable '@i'.

    I have tried it inside a transaction, but same thing.
    Even though the connection is not closed between these statements, Sybase seems to "forget" that I have declared the variable.

    Mostly just curious.... Can anyone explain why this happens.

    A batch is terminated by an end-of-batch signal. With the isql utility, this is the word "go" on a line by itself
    Local variables are declared, named, and typed with the declare keyword and are assigned an initial value with a select statement. They must be declared, assigned a value, and used within the same batch or procedure.
    Now which part of this do you not understand
