[comp.databases] Sybase internals

eric@picard.sbi.com (Eric Ho) (11/14/90)

Hi,

Just wondering if anyone know any fixes to these Sybase internals problems :-

1). I need to delete a column from a table.  People told me that there is no
    easy way to do it (i.e. you either do bcp's to bulk copy out a table and
    basically recreate the table -- doable but yucky.  Or you somehow mark the
    column using sp_rename but this means that I'll do all the
    allocations/management myself -- not a pleasant thought).

2). I need to pass parameters/variables into the from-clause of a select
    statement within the context of a stored procedure - e.g. a stored
    procedure, P, takes 1 argument, x, and I need to use the value of x in the
    from-caluse of a select statement.  Right now, I've resort to write it in
    C but somehow I thought that Sybase's SQL engine should be able to handle
    this -- afterall, this is not a SQL thing by a Sybase specific on its
    stored-procedures.

Just wondering if anyone has any workarounds/fixes on this ?
