The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Unless I misunderstood the "requirements" you could do something like this, using STRSQL or Run SQL Scripts or equivalent:
Suppose you have this table:
CREATE TABLE ORDERS
(ORDERNO INTEGER NOT NULL
GENERATED ALWAYS AS IDENTITY
(START WITH 500
INCREMENT BY 1
CYCLE),
SHIPPED_TO VARCHAR (36) ,
ORDER_DATE DATE)
Then do an INSERT like this:
INSERT INTO ORDERS (SHIPPED_TO, ORDER_DATE)
VALUES('My Sample Company', '2019-05-24' )
Next, run this query to see what was just inserted (to determine the "next number" value just used):
SELECT * FROM ORDERS WHERE ORDER_DATE = '2019-05-24'
Now, suppose you see this result:
ORDERNO SHIPPED_TO ORDER_DATE
536 My Sample Company 05/24/19
Now, you know that the "next number" should be > 536 ...
Run this query to determine if there are any "pending conflicts" ...
SELECT * FROM ORDERS WHERE ORDERNO > 536
Examine the results; that should indicate whether there is any potential trouble lurking ...
(Ideally, no rows should be returned.)
Preferably, do this during "off-peak hours" when no one else is updating that table actively.
It might also be nice to also "clean up" after, by deleting the "dummy" row inserted:
DELETE FROM ORDERS WHERE ORDERNO = 536
No need for embedded SQL, unless you want to develop a tool to automate this process.
Does that help?
