Sp_depends output in a table

sybase

I need to run sp_depends on multiple stored procedures on Sybase to get dependencies. Since I have a lot of stored procedures, I wanted to know if there is any way to force sp_depends output into a temp table and then select from there all dependent objects. If this is possible, I can just run sp_depends from a stored procedure for multiple stored procedures and get the result set in one go.

I tried below without any luck (using Toad):

Insert #test_tbl
exec sp_depends sp_proc

Above gives error as:

"Incorrect syntax near the keyword 'exec'"

Please advise if there is any other efficient way to do this. My goal is to get all dependencies for analysis.

Update:
I do have a way to generate mass 'sp_depends' in excel. Looking for something to run them in one go and get the whole output of supplied objects.
Also, since this is Sybase utility, unfortunately I don't have a way to edit it

A script like this could help you:

isql -Usa -S${ASE_Servername} <<EOF
$password

set nocount on
go
select 'sp_depends '+name from <dbname>..sysobjects
where type='P' and name in ( <list_of_SPs> )
go

EOF

You should only need to drop and recreate the affected NC index.

Saying that, on a test server, you can see the differences in doing this compared to your strategy of dropping all indexes above.

I reckon dropping/creating the single index would be quicker overall because the data will be shifted around twice otherwise: once char to varchar, another to build the clustered index. Then you have the NC creation overhead.

If you subtract 1 from FieldNum and divide the result by 3 using integral division, you will get the following results for FieldNum values of 1 till 6:

FieldNum | (FieldNum - 1) / 3
---------+-------------------
    1    |         0
    2    |         0
    3    |         0
    4    |         1
    5    |         1
    6    |         1

And if you replace / with % (the modulo operator), the results will be like below:

FieldNum | (FieldNum - 1) % 3
---------+-------------------
    1    |         0
    2    |         1
    3    |         2
    4    |         0
    5    |         1
    6    |         2

Now, in case the idea isn't yet clear, the (FieldNum - 1) / 3 expression can be used as a grouping criterion in addition to EntityID (for some reason called EntityNum in your query). And the results of (FieldNum - 1) % 3 could be used to determine particular rows (would-be columns) within the subgroups defined by (FieldNum - 1) / 3.

Finally, if my attempts at verbal description hasn't really succeeded, here's a query that uses the above two expressions to produce the results you are after:

SELECT
  EntityID,
  MAX(CASE (FieldNum - 1) % 3 WHEN 0 THEN Memotext END) AS Date,
  MAX(CASE (FieldNum - 1) % 3 WHEN 1 THEN Memotext END) AS Name1,
  MAX(CASE (FieldNum - 1) % 3 WHEN 2 THEN Memotext END) AS Name2
FROM EQ
WHERE FieldNum BETWEEN 1 AND 6
GROUP BY
  EntityID,
  (FieldNum - 1) / 3
;

And here you can find a "live" SQL Fiddle demonstration. To be honest, the demo uses SQL Server to run the query, but I would expect Sybase to produce the same results. (I'm assuming that FieldNum is an integer-typed column and that Sybase, like SQL Server, automatically applies integral division when both operands of / are integers.)
