Re: Running SQL scripts

I have thoughts about that too.

On that way from RDi to SQL script editor
Strip DECLARE .. prefix and put in comment
Let the developer play with just the SELECT statement
On the way back, prepend from the DECLARE comment

Just thoughts
BTW, would you see what I proposed as a sufficient solution to RFE
http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=11052

Regarding the RFE on visual explain.
http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=11086
When I was discussing this with Mark Anderson he didn't think that
developers had the authority or interest or expertise to use visual explain
to optimize queries beyond noticing the need to index certain tables. But
I see 46 votes on this RFE. Are developers making active use of Visual
Explain?

That's clear Jon, thanks. This thread is morphing into a discussion on
integrating Data Studio with RDi. Imagine you have an existing SQLRPGLE
program with a DECLARE CURSOR as below. You'd like to make some changes
to that SQL statement, what does one do?

Rectangle select, copy, tab to Data Studio, paste. Replace the host
variables with literals, test. Edit, test, repeat. When happy with the
new SQL statement, copy in Data Studio, tab to RDi, select, paste.
Adjust formatting. Save, compile, test. Forgot to replace literals,
wonder why program doesn't work. Replace literals with host variables.
Save, compile, test.

It's better than a sharp stick in the eye, but that's a low bar :-)

There is a small subset of IBM Data Studio which is shipped with RDi.
Now that IBM Data Studio itself is free, you can get the full features
of the product. The SQL running/editing/diagramming is relevant to
IBM i. The query tuning is not since it is geared to LUW DBW (not IBM

i).

I am thinking about developing better integration with RDi eventually,
so I am following this thread with interest.

So if there was an easy way to get embedded SQL into an SQL script
editor in IBM Data Studio would this help write, test queries?

Mad utopian dreamer alert!

Given:
select SYSTEM_COLUMN_NAME, DATA_TYPE, "LENGTH", NUMERIC_SCALE,
COLUMN_TEXT, IS_NULLABLE, "CCSID", SYSTEM_TABLE_NAME,
SYSTEM_TABLE_SCHEMA, COLNO
from SYSCOLUMNS
where SYSTEM_TABLE_NAME = :REF_FILE and
SYSTEM_TABLE_SCHEMA = :REF_LIBR;

I would love to have the test/debug tool/IDE be able to 'declare'
variables :REF_FILE and :REF_LIBR as well as populate them with values

and

then execute this code as-is. Once my SQL is working properly, I could

then

cut / paste it back into my HLL as-is without having to remove literals

and

replace them with host variables.

Similar to the ability SDA has to populate fields for testing (STRSDA

option

3).
