    <p>Another approach that works on Sybase ASE 12.5.4. The table must have a clustered index on id, in order for this to work. Assuming that table name is MYTABLE:</p> <pre><code>declare @strNew varchar(10), @strOld varchar(10), @str1 varchar(1000), @str2 varchar(1000) set @str1 = NULL, @str2 = NULL, @strNew = NULL, @strOld = NULL UPDATE MYTABLE SET @strNew = convert(varchar,id) , @str1 = case when @strNew = @strOld then @str1 + convert(varchar,id_type) + "," else @str1 + '$' + @strNew + '$' + convert(varchar,id_type) + "," end , @str2 = case when @strNew = @strOld then @str2 + convert(varchar,id_ref) + "," else @str2 + '$' + @strNew + '$' + convert(varchar,id_ref) + "," end , @strOld = convert(varchar,id) select id, substring(@str1,charindex("$" + convert(varchar,id) + "$",@str1) + len("$" + convert(varchar,id) + "$"), case when charindex(",$",substring(@str1,charindex("$" + convert(varchar,id) + "$",@str1) + len("$" + convert(varchar,id) + "$") + 1,len(@str1))) = 0 then len(@str1) - (charindex("$" + convert(varchar,id) + "$",@str1) + len("$" + convert(varchar,id) + "$")) else charindex(",$",substring(@str1,charindex("$" + convert(varchar,id) + "$",@str1) + len("$" + convert(varchar,id) + "$") + 1,len(@str1))) end ) + ':' + substring(@str2,charindex("$" + convert(varchar,id) + "$",@str2) + len("$" + convert(varchar,id) + "$"), case when charindex(",$",substring(@str2,charindex("$" + convert(varchar,id) + "$",@str2) + len("$" + convert(varchar,id) + "$") + 1,len(@str2))) = 0 then len(@str2) - (charindex("$" + convert(varchar,id) + "$",@str2) + len("$" + convert(varchar,id) + "$")) else charindex(",$",substring(@str2,charindex("$" + convert(varchar,id) + "$",@str2) + len("$" + convert(varchar,id) + "$") + 1,len(@str2))) end ) as concatenation from MYTABLE group by id </code></pre>

    2. CO@dsm Add the following after the update statement to see the strings that it creates: `print "%1!:%2!",@str1,@str2`. The select statement that follows, extracts appropriate substrings of those strings according to the value of `id`. Care must be taken in counting the correct length. The `case` statement is needed because after the last substring there is not a `,$` anymore, which indicates the end of the substring. Hope that helps.

    3. COI have tested this and it works Ok for a small MYTABLE, but an arbitrarily large table breaks it. Results like the following start showing up: 62126 $16,17,6,6,22:$11,5,11,28,1

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
