Posted on 2006-06-29

Last Modified: 2008-03-10
I created a table with 150 columns using interface in ASA9. Now my DBA wants the SQL of CREATE TABLE.
I dont have time to code and give him the SQL as every column name is lengthy too.
Also I may add, 40 more columns in future.
Is there anyway, I can generate SQL for my existing table ? Kindly help...
Thanks

Sybase Central (shipped with ASA) can do this for you. Right click on the table and you should see something about "Generate DDL".

Sorry, I don't have a copy of ASA to check exactly where it's Sybase Central puts its commands. (Sybase has an unfortunate habit of not standardising the various Sybase Central versions for their different products...) If you have Sybase Central for ASA, it's there somewhere...

That won't give you the SQL but it's a good start. 8-)

here is the procedure, that i use to generate table ddl - it works in ASE, may be it will need some adjustmensts for ASA:

create procedure sp_ddl_get_default
(
    @obj_id int,
    @default varchar(255) output
)
as
  if isnull(@obj_id,0)=0
    select @default=""
  else if not exists  ( select 1 from dbo.sysobjects
                          where id=@obj_id
                            and type="D"
                            and name like "%"+convert(varchar(20),@obj_id) )
    select @default=""
  else
    select @default=text
      from dbo.syscomments
        where id=@obj_id
          and colid=1
go

create procedure sp_ddl_user_table_columns
(
    @table_id int
)
as
  declare @col_name varchar(30),
    @type_id int,
    @type_name varchar(30),
    @status tinyint,
    @length int,
    @cdefault int,
    @prec tinyint,
    @scale tinyint,
    @i tinyint,
    @c tinyint,
    @nulltype varchar(20),
    @colname varchar(30),
    @typename varchar(30),
    @default varchar(255),
    @text varchar(255)

  select @c=count(1),
      @i=1
    from dbo.syscolumns
      where id=@table_id
  declare cr cursor for
    select c.name,c.usertype,t.name,c.status,c.length,c.prec,c.scale,c.cdefault
      from dbo.syscolumns c, dbo.systypes t
        where c.id=@table_id
          and c.usertype=t.usertype
        order by c.colid
    for read only

  open cr
  fetch cr into @col_name,@type_id,@type_name,@status,@length,@prec,@scale,@cdefault
  while @@sqlstatus=0
  begin
    select @nulltype=case
        when @status & 128 = 128 then "identity not null"
        when @status & 8 = 8 then "null"
        else "not null"
      end,
      @type_name=case
        when @type_id>=100 then @type_name
        when @prec is not null then @type_name+"("+convert(varchar(3),@prec)+","+convert(varchar(3),@scale)+")"
        when @type_name in ("binary","char","varbinary","varchar") then @type_name+"("+convert(varchar(3),@length)+")"
        else @type_name
      end,
      @text="  %1! %2! %3! %4!"+case when @i=@c then "" else "," end,
      @i=@i+1
    select @colname=@col_name,
      @typename=@type_name
    exec sp_ddl_get_default @cdefault, @default output
    print @text,@colname,@typename,@default,@nulltype
    fetch cr into @col_name,@type_id,@type_name,@status,@length,@prec,@scale,@cdefault
  end

  close cr
  deallocate cursor cr


go
