问题
I am getting issue while inserting a new record to the table in Oracle database. The error description says-
SQL Error: ORA-01401: inserted value too large for column
How would I come to know that which column is having large value as I am having 60 columns in the table.

SQL Error: ORA-01401: inserted value too large for column
You are trying to insert value larger than the specified size for the column.
How would I come to know that which column is having large value as I am having 60 columns in the table.
The error will certainly have the table and column name with the actual size being inserted and the maximum size allowed.
For example,
SQL> CREATE TABLE t(A VARCHAR2(2));
Table created.
SQL>
SQL> INSERT INTO t VALUES ('123');
INSERT INTO t VALUES ('123')
*
ERROR at line 1:
ORA-12899: value too large for column "LALIT"."T"."A" (actual: 3, maximum: 2)
SQL>
In the above example, the error clearly states "column "LALIT"."T"."A" (actual: 3, maximum: 2)" where LALIT is the SCHEMA, T is the TABLE and A is the COLUMN. The size specified for column A while table creation was 2, however, the actual insert had 3.
UPDATE Regarding confusion between ORA-01401 and ORA-12899.
From Oracle 10g and higher, the ORA-01401 was modified to ORA-12899 which is more explicit and has the details about the SCHEMA, TABLE and the COLUMN which caused the error.
Additional information Just in case if anyone is interested:
There is a counterpart of ORA-01401, i.e. ORA-01438 which is applicable in case of NUMBER. This seems to be unchanged.
For example,
SQL> CREATE TABLE t(A number(2));
Table created.
SQL>
SQL> INSERT INTO t VALUES (123);
INSERT INTO t VALUES (123)
*
ERROR at line 1:
ORA-01438: value larger than specified precision allowed for this column
