Hi James,

The translaters get better and better (at least for simple sentences). ;)

@1: If you change the date format in STRSQL with F13 option 1 it should be preserved for all sub-sequent calls.

@2: I prefer to include an SET OPTION statement in all my embedded SQL programs (sometimes I need to compile on our customer's machines, and without the SET OPTION statement, I've always remember the settings). But if your company, manager etc. will allow it you can change the defaults of the CRTSQLRPGI system command with the CHGCMDDFT command.

Mit freundlichen Grüßen / Best regards

Betreff: Re: SQL returns "++++++++++" for MIN(DATE)

Birgitta,

Vielen Dank! Ist es nicht toll, dass auch ein Idiot wie ich verwenden kann Google Translate und Ton intelligent? :)

1. I used STRSQL and F13 to change the date format. It now displays the date as it should. Is there a way to change that so I don't have to change it every time I use SQL?

2. I'm using CRTSQLRPGI to compile programs. Is there an easy way to change the default for that command so I don't have to change it each time?

Many thanks!!

For each host variable used within embedded SQL the SQL precompiler
generates an additional variable named SQLXXXXX.
In case of the date variables the precompiler does neither use the
date format specified within the D- specs nor those defined in the
H-specs but use the date format specified within the compile command option DATFMT.
The default for this date format is *JOB which normally means a date
format with a 2 digit year.
The problem occurs as soon as your RPG variable initialized with a
value lower than 01/01/1940 into the additionally defined SQL variable.
To circumvent this problem just specify a DATEFMT with a 4 digit year, i.e.
ISO, EUR, USA, JIS in the compile command.
An even better alternative is to include a SET OPTION statement in
your RPG program where a date format with a 4 digit year is specified.
Attention the SET OPTION statement must physically be the first SQL
statement in your source code.

BTW in STRSQL just change the date format with F13 --> Option 1 to a
date format with a 4 digit year.

An: RPG programming on the IBM i / System i
Betreff: SQL returns "++++++++++" for MIN(DATE)

I have the following code in an RPG ILE program:

/EXEC SQL
+ DECLARE C1 CURSOR FOR
+ SELECT MIN(HIDATE)
+ FROM MHIST
/END-EXEC

FWIW, all my date fields are ISO (YYYY-MM-DD).

The program was blowing up when I tried to move the result to another
date field, saying I had an invalid date. I looked at the dump and
the date field contained "++++++++++".

I did STRSQL, ran the command, and got the same thing. I used Query
and it shows the minimum (oldest) date as "1915-01-05". Ran the SQL
version again but this time didn't ask for MIN. Instead asked to see
the data and sorted by date. All the dates prior to 1940-01-01 are "++++++++++".

I know I can sort the records by date, SETLL, and READ but I figured
this would be faster and more efficient.

Is there a "Yes, I really have data before 1940 that I'd like to see"
switch somewhere in SQL that I need to flip?

TIA.
