Question

How can I insert into table with different input using / ,with date datatype?

insert into run(id,name,dob)values(&id,'&name',[what should I write here?]);

I'm using oracle 10g.

Since dob is DATE data type, you need to convert the literal to DATE using TO_DATE and the proper format model. The syntax is:

TO_DATE('<date_literal>', '<format_model>')

For example,

SQL> CREATE TABLE t(dob DATE);

Table created.

SQL> INSERT INTO t(dob) VALUES(TO_DATE('17/12/2015', 'DD/MM/YYYY'));

1 row created.

SQL> COMMIT;

Commit complete.

SQL> SELECT * FROM t;

DOB
----------
17/12/2015

A DATE data type contains both date and time elements. If you are not concerned about the time portion, then you could also use the ANSI Date literal which uses a fixed format 'YYYY-MM-DD' and is NLS independent.

For example,

SQL> INSERT INTO t(dob) VALUES(DATE '2015-12-17');

1 row created.

Solution 2

date must be insert with two apostrophes' As example if the date is 2018/10/20. It can insert from these query

Query -

insert into run(id,name,dob)values(&id,'&name','2018-10-20')

Solution 3

let suppose we create a table Transactions using SQl server management studio

txn_id int,

txn_type_id varchar(200),

Account_id int,

Amount int,

tDate date

);

with date datatype we can insert values in simple format: 'yyyy-mm-dd'

INSERT INTO transactions (txn_id,txn_type_id,Account_id,Amount,tDate)
VALUES (978, 'DBT', 103, 100, '2004-01-22');

Moreover we can have differet time formats like

DATE - format YYYY-MM-DD
DATETIME - format: YYYY-MM-DD HH:MI:SS
SMALLDATETIME - format: YYYY-MM-DD HH:MI:SS 

Solution 4

insert into run(id,name,dob)values(&id,'&name',[what should I write here?]);

insert into run(id,name,dob)values(&id,'&name',TO_DATE('&dob','YYYY-MM-DD'));
