How to Comment Out Lines of Code in a Pass Through Query In MS Access 2016

I'm working with a MS Access database that was developed by someone else.

I've converted this database to work in the Windows 10 environment with MS Access 2016.  Since converting the database to MS Access 2016, the comments that are in the pass through queries are causing issues.

The comments are commented out as follows:

/*  comments  */

Is there a way to comment out lines in a Pass Through Query in MS Access 2016 (the above way doesn't work in this version of Access)?

Thanks,

I wonder if something else is at play. The following works fine for me, using Access 2016 against SQL server 2012
/*This is a comment */
Select top 1 *  from UserRoles.tblUser
/*This is a comment */

Open in new window

Perhaps you haven't updated the connection string? Or installed the right driver?

Anders Ebro,

Yes I've updated the connection string, and if I remove the comments it runs fine.

have you tried the "--" comment prefix?

What is your backend?
could you try the following SQL and see if it runs:
/*This is a comment */
Select @@SPID
/*This is a comment */

Open in new window

Just as a way of testing whether it might be related to your SQL in combination with the comment, rather than something else

Also, it's not SQL Server it's Oracle.

Here's the pass through query:

/* ******************* TODO: CHECK FOR DUPLICATES *********** */

SELECT DISTINCT

   EDMADMIN.CD_WELL.COMPLETION_WELL_ID,
   EDMADMIN.CD_WELL.WELL_ID,
   EDMADMIN.CD_WELL.CONDUCTOR_INSTALL_DATE,
   EDMADMIN.CD_WELL.FIELD_NAME,
   EDMADMIN.CD_DATUM.DATUM_ELEVATION

FROM
   EDMADMIN.CD_WELL,
   EDMADMIN.CD_DATUM

WHERE

   EDMADMIN.CD_WELL.WELL_ID = EDMADMIN.CD_DATUM.WELL_ID(+) AND
   EDMADMIN.CD_WELL.COMPLETION_WELL_ID IN (<WINS_NO>) AND

   UPPER( EDMADMIN.CD_DATUM.IS_DEFAULT) = 'Y' 
  /* UPPER( EDMADMIN.CD_DATUM.DATUM_NAME) = 'RKB' /* removed 4/8/15  */

Open in new window

It looks like you have an unfinished comment in hte last line:
/* UPPER( EDMADMIN.CD_DATUM.DATUM_NAME) = 'RKB' /* removed 4/8/15  */

Open in new window


Try to replace that with
/* UPPER( EDMADMIN.CD_DATUM.DATUM_NAME) = 'RKB'  removed 4/8/15  */

Open in new window

Anders Ebro,

No, what you posted didn't run.  I get the following error (see attached document).

What I posted worked for SQL server. I must admit I have no experience with Oracle. But in SQL Server a unfinished comment is not allowed, so try to fix that (per my previous post) and see if that helps.

Anders Ebro,

I tried your last posting ID: 41987946 and I still get the error that is contained in the document I uploaded in my last posting.

Thoughts??

Thoughts?  Yes ... probably need to post in the Oracle section as well.

>> But in SQL Server a unfinished comment is not allowed,

Also not in Oracle but technically it is finished:  There is only one close.  Oracle should ignore "extra" opens.  It sees a comment start, it continues until it sees a comment end.

Now back to the error:  No idea really.

The error text is real informative:  http://psoug.org/oraerror/ORA-24374.htm

Even though it is an Oracle error message, I'm not sure it is coming from the database.  It might be coming from the Oracle client.

Are you also using upgraded Oracle drivers?  Are those drivers compatible with the version of Oracle database you are connecting to?

slightwv,

I'm not sure about the drivers.  I'll have to reach out to the IT guys.

If you copy the SQL and paste it into whatever substitutes for for the new query window in SSMS in Oracle, does the query work?

Sorry for the delay.

Pat, I don't have access to SSMS in Oracle.
