Time datatype in Oracle Database

[Osiris Dragon]

Hi Guys,

I have a table where I where I can enter date in HH:MM format.

I have already created the table as:

CREATE TABLE "test"."SLA"
  (
    "SLAID"    NUMBER(10,0) NOT NULL ENABLE,
    "SLALEVEL" VARCHAR2(200 BYTE) NOT NULL ENABLE,
    "WEEKDAY_START_TIME" TIMESTAMP (6),
    "WEEKDAY_END_TIME" TIMESTAMP (6),
    "WEEKEND_START_TIME" TIMESTAMP (6),
    "WEEKEND_END_TIME" TIMESTAMP (6),
  )
 

How can I format the TIMESTAMP datatype so I can enter values like 23:45 or 11:55 etc?

Currently if I try to do so I get the error:

Row 1: ORA-01847: day of month must be between 1 and last day of month
ORA-06512: at line 1


I have tried declaring them as:

"WEEKDAY_START_TIME" TIMESTAMP 'HH24:MM'
 

with no luck. Any help will be appreciated.

Thanks.

What do you mean

What do you mean format?

Timestamp is used for storing date with time.
So you can insert value in the following way

insert into table values(to_timestamp('23:40','HH24:Mi'))

Well I was using Oracle SQL developer to enter values (not using the INSERT query) manually in a data entry table just like in a spreadsheet.

And I get the error why I try to commit the changes:

Row 1: ORA-01847: day of month must be between 1 and last day of month
ORA-06512: at line 1


By formatting I meant tweaking the TIMESTAMP datatype in ALTER TABLE statement in such a way so I can enter the values without the above error.

Something like this (just as example, I know this is wrong)

ALTER TABLE
MODIFY column_1 TIMESTAMP='HH24:MM'
 

Something like that or any other Datatype that can solve this problem.


Many thanks. But I guess INSERT statement is one way around it.

Well I think Oracle has not any datatype for storing only hours and minutes. When you use timestamp date also will be stored.
