Hi all,
I have some code that works in Access but now I want to forward the code to our IT department to make a view in our SQL database.
Could anyone please help me convert it so it is correct for Oracle SQL and not Access SQL if that makes sense?
Thanks in advance
Chris
SELECT T1.*, (SELECT TOP 1 T3.[SMN_DATEC]-1 FROM
(SELECT T2.[DET_NUMBERA], T2.[SMN_DATEC] FROM [CHRISCS_EMSAL] AS T2 ORDER BY [DET_NUMBERA],[SMN_DATEC]) AS T3 WHERE T3.[DET_NUMBERA] = T1.[DET_NUMBERA] AND T3.[SMN_DATEC] > T1.[SMN_DATEC] ) AS EndDate, T1.[DET_NUMBERA], T1.[SMN_DATEC]
FROM CHRISCS_EMSAL AS T1
ORDER BY T1.[DET_NUMBERA], T1.[SMN_DATEC];
I have tried to test it in ORACLE SQL Developer but am getting the error:
Error at line 1, column 25:
ORA-00923: FROM keyword not found where expected

It appears you are using two subqueries in the expression, and Access does subqueries somewhat differently than ANSI SQL, which is closer to Oracle. Some versions of Access let you use ANSI SQL, or something close to it, so you might try changing that option in Access and see what it does. Unfortunately I am not conversant with Oracle, so hopefully someone else with that expertise can make further suggestions.

Oracle does not use TOP(n). One alternative is to filter by ROW_NUMBER().

SELECT T1.*,

(SELECT END_DATE

FROM (SELECT T3.SMN_DATEC-1 AS END_DATE,

ROW_NUMBER() OVER(ORDER BY DET_NUMBERA,SMN_DATEC) AS ROWNO

FROM (SELECT T2.DET_NUMBERA,

T2.SMN_DATEC

FROM CHRISCS_EMSAL AS T2

ORDER BY DET_NUMBERA,SMN_DATEC) AS T3

WHERE T3.DET_NUMBERA = T1.DET_NUMBERA

AND T3.SMN_DATEC > T1.SMN_DATEC ) T4

WHERE ROWNO = 1) AS EndDate,

T1.DET_NUMBERA, T1.SMN_DATEC

FROM CHRISCS_EMSAL AS T1

ORDER BY T1.DET_NUMBERA, T1.SMN_DATEC;

This code is untested because I don't have an Oracle server nor DDL and sample data.

Hi Luis,

Many thanks for your reply, I am getting the following error:

Error at line 7, column 38:

ORA-00907: missing right parenthesis

Thanks again.

Thanks again.

Are you using exactly that code by itself? I can't find any missing parenthesis.

Yes your code only :/

when the error appears it points to the letter "A" in the word "AS" in the following line

FROM CHRISCS_EMSAL AS T2

I'm not sure what's the problem. The code should be working and there's no missing parenthesis. That's just another reason why I hate Oracle.

Maybe someone else can help.

By the way, the code works in SQL Server, and should work with most RDBMS as everything is under the SQL standard.

It must be something on my side then, I really appreciate you spending the time writing the code for me.

Thanks again

It's basically on the Oracle side, but I haven't used Oracle recently to be sure what it is. Try an Oracle forum for more help.

I think LEAD has been in Oracle for sometime.

Something like:

SELECT *

,LEAD(SMN_DATEC, 1) OVER (PARTITION BY DET_NUMBERA ORDER BY SMN_DATEC) - 1 AS EndDate

FROM CHRISCS_EMSAL

ORDER BY DET_NUMBERA, SMN_DATEC;
