Hi All,

My requirement is to fetch records from table x whose last update time stamp is between yesterday 00.00.00.000000 and yesterday 23.59.59.999999.

for example if suppose i am running the query in batch spufi today say current date is 2015-05-24. then i have to get records from the table which are got updated between '2015-05-24.00.00.00.000000' and '2015-05-24.23.59.59.999999'.

is the above query is possible. I am planing to execute the query in batch and schedule it thru a job which will run daily and generate report.

I have the last update column in the table.

Hi ,

Try this in where clause of your SQL

where DATE( timestamp_col - 1 DAY) = CURRENT DATE - 1 DAY

Hope this helps !!

Regards,
MJ

they are contradictory.

Declare something like this and use it in where condition.

Code:
01 date-range
   05 date-to
        10 current-date PIC X(10).
        10 high-timestmp PIC X(16) VALUE '.23.59.59.999999'.
   05 date-from
        10 current-date PIC X(10).
        10 low-timestmp PIC X(16) VALUE '.00.00.00.000000'.

it looks like you are overshooting ...
wouldn' t it be simpler just to ask for the rows with a last update date of yesterday ???

"- 1 DAY" is a nice option, but once is enough:
Code:
WHERE DATE(timestamp_update) = CURRENT DATE - 1 DAY
