Thread: SQL statements error in pgsql 16 but not in pgsql 12

SQL statements error in pgsql 16 but not in pgsql 12

Hi,

 

I was trying to upgrade our database from version 12.18 to the latest 16.3

 

After upgrading, the application has reported errors or “junk info” in the sql command line.

 

Example SQL code:

Message: ERROR: 42601: trailing junk after numeric literal at or near "19749O"
SQL: SELECT bb,mass,classifier,lot
FROM lab.pt_f003_view
WHERE (lot = 19749OR lot= 19750)
ORDER BY lot,bb

 

 

The above sql command works in version 12 but does not work in version 16 due to missing space in “WHERE (lot = 19749OR lot= 19750)”

 

Why did this work before and now it does not work?

 

Thanks

 

Frank Komsic

It seems to be a side-effect of supporting non-decimal literals.

This comment in particular refers to a v15 change that is probably related if you want to dive deeper.

Suffice to say, we became more strict here since v12 and you will need to modify the query accordingly.

cross check
WHERE (lot = 19749 OR lot= 19750)

where the OR is tagged to numeric 19749.

Thank you for your reply.

 

I gather I will have to lookover the entire code and set the SQL statements correctly.

 

Thanks

That's not a great choice of word.  In any case, the point here
is that the SQL standard requires some whitespace between a number
and a following word, and starting from PG 15 we're enforcing that
to reduce ambiguity.
