Time stamp and Date comparision

Hi ,

In my table I have timestamp field (ABCD) . I will get date(Char 10) as input ( its a Pl/1 program).

Now i have to compare this input date with timestamp field
i.e. first 10 chars of Timestamp with the input date.
For instance , Timestamp - 2008-01-16--08.39.21.480239
and Input date - 2008-01-16 . so first 10 of timestamp(2008-01-16) is to be compared with input date and if it is equal i have to fetch the records.

I tried for the above in the following manner

1) I used substr(ABCD,1,10) = :input
but i got message as ABCD is not a char field

2) I used Date fucntion which gives date in format 16 Janauary 2008.
But while converting input as wk_input = date(input).
I am getting error as 'Excess arguments for DATE built-in ignored'

Pls let me know how can I get first 10 of timestamp to compare with Input field .

Thanks in advance,
Rasha

timestamp is a type date/time field. substring works with characters.

so,

cast abcd to a character string and then use the substr.

Hi,

You can use CHAR(DATE(TIMESTAMP)) OR
as you used above substr(char(ABCD),1,10) = :input

I think this should work

Thanks,

When you ask for the CHAR version of a date or timestamp you should specify the format. CHAR(DATE, ISO) will give it in YYYY-MM-DD format, the default could be different depending on what is specified when DB2 is installed.

Which one is worked
out of given 3 CHAR(DATE(TIMESTAMP)) or substr(char(ABCD),1,10) = :input or CHAR(DATE, ISO)

Also casting is possible in COBOl.
