#SQL

Hello,

Is it possible see the execution plan of a SQL sentence in IRIS?

Like this:

explain plan for
select  e.ename,r.rname
from    employees  e
join    roles       r on (r.id = e.role_id)
join    departments d on (d.id = e.dept_id)
where   e.staffno <= 10
and     d.dname in ('Department Name 1','Department Name 2');

That returns this:

I need iterate multiple times the same ResultSet. How can I do a rewind on it?

Hi all,

I am using %Library.ResultSet to execute my query which I have something like this.
Query GetABC() As %SqlQuery [SqlProc]{

}

After I execute this query and a resultset it returns from this. Now What I want to know is the SQL statement which will have the values dynamically added into while execution.

I try it with the COLLATE instruction, but doesn't work.

Any ideas ?

Tkanks.

Hello,

When i click on the menu to run the Data import wizard from MP, i receive following CSP error

It is happening for all the namespaces. Looks like some permission issue. Same issue with Data Export wizard. Help to resolve this will be appreciated.

Thanks,

Is it possible to call java programs inside SQL statements, like the new LOAD Data, or is this just internal?

Hi,

Do you know how to export SQL errors to a text file from a terminal session in Caché?

Thanks

Hi, folks!

When you deploy DeepSee solutions you often do not want grant a User %All Role to work with a particular Dashboard.

Consider a Dashboard 'Dash' with a few widgets where listings are being used.

If you manage a Role to get access to the Dash you need to grant access to %DB_DBNAME resource to have a database access, grant access to a Dashboard resource (if any) and ... grant SELECT accesses to all the tables involved in SQL queries being used in all the listings of widgets.

I configured a SQL inbound adapter to monitor my local Cache database.

But I got "ERROR <Ens>ErrOutConnectFailed: ODBC Connect failed for 'SAMPLES' /
'' with error ERROR #6022: Gateway failed: DSN/User Connect."

Same error if the DSN setting is blank or set to my namespace.

Question is whether SQL inbound adapter is for external database server ONLY?

When using INSERT OR UPDATE command,

How does the command know if the row exists?

Hi,

Is it possible to use the value of a column that is populated by its own subquery, in the WHERE clause of the outer-query ?

The following fails (it does not parse syntactically):

SELECT A, B, (SELECT S1 FROM Table2) "C" FROM Table1 WHERE C>10

I guess I could wrap it up as in inner query of it's own - this way (which works) :

Select * from 
(SELECT A, B, (SELECT S1 FROM Table2) "C" FROM Table1)
where C>10

but I was wondering if there was some syntax in the original snippet that I could do instead.

Thanks - Steve
