I have little knowledge on oracle. I tried to create a function like below.
CREATE OR REPLACE FUNCTION "BOOK"."CONVERT_TO_WORD" (totpayable IN NUMBER) RETURN VARCHAR
AS
totlength NUMBER;
num VARCHAR2(14);
word VARCHAR2(70);
word1 VARCHAR2(8);
BEGIN
SELECT LENGTH(totpayable) INTO totlength FROM dual;
WHILE totlength>0
LOOP
SELECT SUBSTR(totpayable,totlength,1) INTO num FROM dual;
IF num='-' THEN
word1:='(Excess)';
END IF;
IF num='0' THEN
word1:='Zero';
END IF;
IF num='1' THEN
word1:='One';
END IF;
IF num='2' THEN
word1:='Two';
END IF;
IF num='3' THEN
word1:='Three';
END IF;
IF num='4' THEN
word1:='Four';
END IF;
IF num='5' THEN
word1:='Five';
END IF;
IF num='6' THEN
word1:='Six';
END IF;
IF num='7' THEN
word1:='Seven';
END IF;
IF num='8' THEN
word1:='Eight';
END IF;
IF num='9' THEN
word1:='Nine';
END IF;
word:=word1||' '||word;
totlength:=totlength-1;
END LOOP;
RETURN word;
END ;
when I try to execute it, I am getting errors as below:
ORA-01031: insufficient privileges
01031.00000 - "insufficient privileges"
*Cause: An attempt was made to change the current username or password without the appropriate privilege. This error also occurs if attempting to install a database without the necessary operating system privileges. When Trusted Oracle is configure in DBMS MAC, this error may occur if the user was granted the necessary privilege at a higher label than the current login.
I have given privileges to the user using this command:
grant all privilege to book;
