Hi,
I have a problem using the odbc datasource reader to execute a sql command on a progress database. My query is something like:-
select max(id), sum(amount) from my_table
OR
select a, b, c, recid(my_table) from my_table
which produces external columns and output columns with no name. The progress sql doesn't support using aliases on column names and setting validateexternalmetadata to false and manually naming the input and output parameters in the 'Advanced Editor' doesn't seem to work either. I either get the error 'The name for output column "" is blank and columns can not be blank' or if I add my own column names in the input and output parameters it fails in the pre-execute phase saying it can't find a column in the datasource with name 'myalias'
I can get around the aggregate functions by transfering all the data and doing the aggregate on the local server but I also need to call functions such as recid() which I can't work around. SQL2000 DTS ignored these things and matched as best it could where SQL 2005 IS seems overly strict.
Has anyone encountered similar problems and does anyone have any ideas? I'm currently at a loss :(
Hi,
I don't know about 'Progress'. But just in a curiosity I am asking this. If you can't have a column alias how will you create a view using the statements that you have mentioned above. If there is any workaround there, u better try the same thing.
|||At a stretch, it should be possible to create a script source which would execute this query and assign the results to columns in the data flow.
another possibility may be to use an Execute SQL task - if you're not returning too many rows.
However, are you sure column aliases are not supported? The Progress online documentation appears to suggest that it may be. there may be a way in progress to make this happen.
