Question

I have the following sql query (this is a transpose query to get comma separated table)

    SELECT CAST ((SELECT taxonomy_id + ','
                  FROM content
                  FOR XML PATH('')) AS bigint) AS NewTaxonomytableName

But I am getting Error converting data type varchar to bigint.
The table taxonomy_id is a bigint

Any ideas?

UPDATE:

SELECT CAST ((SELECT CAST(taxonomy_id AS varchar) + ',' AS Expr1 FROM taxonomy_item_tbl FOR XML PATH('')) AS varchar) AS Expr1

Running this gives me one row.

But in fact it is not right for me. It needs to comma separate only the taxonomy_id’s for a specific content_id.

An example:

content_id taxonomy_id
1          15 
1          16 
5          24 
5          19

needs to be:

content_id taxonomy_id
1          15,16
5          24,19

I am really stuck with this for 8 hours. If anyone can help me I will really appreciate it…

Thanks

The problem is that you aren’t converting taxonomy_id to a bigint, you’re converting a comma-seperated list of them to a bigint.

Try this instead:

SELECT CAST ((SELECT CAST(taxonomy_id as varchar) + ','
              FROM content
              FOR XML PATH('')) AS varchar(max)) AS NewTaxonomytableName

EDIT
Ok, since I’m not exactly certain of your table structure, you might need to play around with this to get exactly what you want, but the theory is right.

SELECT DISTINCT c.content_id,
    CAST((SELECT CAST(taxonomy_id as varchar) + ','
          FROM content
          WHERE content_id = c.content_id
          FOR XML PATH('')) AS varchar(max)) AS taxonomy_ids
FROM content c
