Question

Formate Date as yyyy/mm/dd in select statement with Firebird 2

Asked by: henryreynolds

Good day,

I need to do a select statement where I can format a Date Field to a string field in the format of yyyy/mm/dd.

I have created a work table where I insert values into, my work table have a Field called ExDate declared as char(10).
I do a insert into this table from a table where I have a Field Called ArrDate declared as Date variable, I need to convert this ArrDate to a string but in the following format yyyy/mm/dd.

The reason why I need the fields as a string is, because this field is updated to null sometimes if it met a certion condition, If I use a Date variable and update it to null then I get a value of 1899/01/01 I dont want that.

I have tried the following but dont know how the get a leading zero in front of the month and day if the day or month is less then ten.

select EXTRACT(YEAR FROM ArrDate)||'/' || EXTRACT(MONTH FROM ArrDate)||'/' || EXTRACT(DAY FROM ArrDate) from Par

Please show how I can format this select statement.

thanx

If a field has null in it I would expect null back, so your easiest thing would be to fix that

the way to deal with your format issue above is to use a stored procedure, something like

create or ALTER PROCEDURE my_proc(DATE_IN TIMESTAMP)
RETURNS (RES_STR CHAR(10))
AS
     declare variable num1 Integer;
     declare variable num2 Integer;
     declare variable num3 Integer;
begin
num1 = EXTRACT(year FROM :DATE_IN);
num2 = EXTRACT(month FROM :DATE_IN);
num3 = EXTRACT(day FROM :DATE_IN);

if (num2 > 9) then
res_str = cast(num1 as char(2)) || '/' || cast(num2 as char(2)) ;
else
res_str = cast(num1 as char(2)) || '/0' || cast(num2 as char(1));

if (num3 > 9) then
res_str = res_str || '/' || cast(num3 as char(2)) ;
else
res_str = res_str || '/0' || cast(num3 as char(1));
suspend;
end
 ^

and call it as select * from my_proc(ArrDate);

Morning NickUpson

Is there now way where I can format the Date variable in a select like with Sql server.

select convert(char(15),getdate(),111) // this will  convert a date variable to char 2007/01/08

Thanx

no, not when you want the leading zeros. firebird & interbase don't have such non-standard sql capabilities. To put the leading zero in place you need 'if'

you can do

select cast(arrdate as char(25)) from Par

but that may not give the correct format either (but does seem to give the leading zero, with enough substring calls it should be possible)

Hi NickUpson

I am very confused, I hope you can answer me on the following.


If for example I have a table Test declared as Follows :

create table Test (ArrDate Date, RValue numeric(9,2))

insert into Test (ArrDate,RValue) VALUES (null,99.99)

if I select now from Test I get the following
null,99.99

Previously I said I got 1899/01/01, I need to know from you if I put a null value any type field , will I always get a null return,
where do you think I got the 1899/01/01 value from.

Will the null make the field as empty like '' ???

Sorry I hope you understand what I am trying to say now, but If the null will return a empty value , then my problem is 100% solved.
The reason why I want sometimes a null is because some of the data I must return must not have a date value in, but other data must have a date value in.
I want in my procedure to update some records and set ArrDate = null when it met a certain condition, and then it must not show anything in delphi if it is a null.

Here is a example of my report in delphi.

Client       Status   Arrivial Date
A             Active   01/01/2007
B             NOT    
C            NOT
D           ACTIVE  01/01/2007
E          ACTIVE    01/01/2007

this is how the data must look, but it seems the null update work now.

thanx
henry

> I need to know from you if I put a null value any type field , will I always get a null return

yes

> where do you think I got the 1899/01/01 value from.

cast(0 as date) might do that

make sure you are VERY clear on empty string is the same as '' is NOT the same as NULL, (although you can choose to display NULL as '' if you wish by using coalesce(fieldname, '')
