I want to create an insert script which will be used only to insert one record into one table.
It has 5 columns and one of them is of type CLOB.
Whenever I try, it says can not insert string is so long . larger than 4000.
I need an insert statement with clob as one field.
INSERT INTO tbltablename
(id,
NAME,
description,
accountnumber,
fathername)
VALUES (1,
N'Name',
clob'some very long string here, greater than 4000 characters',
23,
'John') ;
This question is related to
oracle
Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.
note I changed the varchar2(32000) to CLOB
set serveroutput ON
CREATE TABLE testclob
(
id NUMBER,
c CLOB,
d VARCHAR2(4000)
);
DECLARE
reallybigtextstring CLOB := '123';
i INT;
BEGIN
WHILE Length(reallybigtextstring) <= 60000 LOOP
reallybigtextstring := reallybigtextstring
|| '000000000000000000000000000000000';
END LOOP;
INSERT INTO testclob
(id,
c,
d)
VALUES (0,
reallybigtextstring,
'done');
dbms_output.Put_line('I have finished inputting your clob: '
|| Length(reallybigtextstring));
END;
/
SELECT *
FROM testclob;
"I have finished inputting your clob: 60030"
