Sybase查询：ASE中LIST（）的替代方法

Question

Could you please help me to find out below query in Sybase.

I want a comma separated Row list. There is one LIST() aggregate function but I can't use that because I am using Adaptive Server Enterprise.

Is there any alternative query exist in Sybase to get LIST() ?

Answer 1

In ASE there are basically two options: (i) use a loop-based algorithm like a cursor (ii) use a little-known feature of the ASE UPDATE statement which can accumulate values over subsequent rows into a variable.

As for the latter, basically the idea is not updating any columns, but scanning through the rows like this:

update Sales
set @cnt = @cnt + 1,
    @sum = @sum + Amount

For full details, see my book www.sypron.nl/ttr.

Answer 2

I have solved that with below technique,

I have created one #temp table and loop through cursor and inserted comma separated value in #temp table.

Now in main select query join with #temp table
