how to resolve 'Update operation attempted on non-updatable query'?

问题

I am working on a sybase-iq server Sybase IQ/15.4.0.3014

I have a working query to update one field of a table as below

update  table1
set     a.field1= b.some_value
from    table1 a,
        table2 b
where   a.id = b.id

This is working fine when I execute it from a sql session. When it is being called from a high level application, I am getting the below error for the above query

SQL Exception code is 7301
Update operation attempted on non-updatable query

I am not able to find why I am getting this error. Is there any solution to amend the query. Searching on the internet is not helping much.

Have anyone come across such issue?

回答1:

You attempted an insert, update, or delete operation on a query that is implicitly read-only. You're trying to update system table or table which cannot be changed in that manner.

I suggest to double check that table_name is actually a table, but not a view. If it is a view, you may see its definition with sp_helptext command, such as

sp_helptext 'view_name'

or

sp_helptext 'schema_name.view_name'
