So I'm getting errors when there's a call to COALESCE with only a single
parameter. (Why would we write code like that? - because nobody thought
to spot it as a special case in our query generation code, perhaps.)
So what does the Firebird book say? - well, my copy appears to say
COALESCE (valu
Hey everyone,
one short question, why is the Result of
coalesce(:variableVarchar(10),'NULL') not ,NULL' but rather 'NULL '
with blanks from varchar(10) length?
Thank you.
Best regards.

What tool/application are you using to evaluate the result?
As Dmitry and Mark have already pointed out, the result should be a VarChar(10
Okay,
Thanks @ll! It was in fact a char instead a varchar item.

I've got a query like:
SELECT ... FROM TBL WHERE COALESCE( FIELD1, FIELD2 ) = 12345
where FIELD2 is the primary key and FIELD1 also has an index (in fact
it's a foreign key back to FIELD2). This results in a table scan.
However expanding the COALESCE by hand:
SELECT ... FROM TBL WHERE ( FIELD1
Hi all
I have the following in my SELECT statement
COALESCE(CAST(tPB.dBillDt AS TIMESTAMP), '') AS tDocDt
The COALESCE() converts the CAST()ed TIMESTAMP to ANSI standard 2014-05-03
00:00:00.
CAST(COALESCE(tPB.dBillDt, '') AS TIMESTAMP) AS tDocDt
The CAST() converts the COALESC
Hello,
in the further version of firebird I can execute the following and get the
real value of m (exists in tlager_sum)

from tteile a left join tlager_sum b on (a.teilenr = b.teilenr)

Hi Bhavbhuti,
I do not know the exact solution, but I'd say:

converts timestamp inside servers environment to a string - the
returning client receives a string and does not know about it's datatype
- yet does not a apply specific translati
By the way, Bhavbhuti,
CAST(COALESCE(tPB.dBillDt, '') AS TIMESTAMP) AS tDocDt
will fail if tPB.dBillDt is null since '' cannot be converted to a timestamp
(it is neither a timestamp nor null).

Svein, Bhavbhuti has a background as a Visual FoxPro developer and in that
language exist empty dates.
Probably is the reason why he had casted an empty string as a timestamp.
The same thing had happened to me when I was learning SQL.
Greetings.
Walter.

Hell Mark,
I would get all material, where the minimum inventory amount iss maller the the

Tlager_sum contains the inventory amount, tteile.minb the theoretical minimum
amount it should be.
