java.sql.SQLSyntaxErrorException: ORA-01722: invalid number

This blog explains the root cause for ORA-01722 and steps need to be taken to resolve this issue.

Reason :  If you are trying to set a bind parameter value i.e String and comparing against  Numeric value you will see this error . For eg : You have empID = :BindEmpID , If you pass the :BindEmpID value as 'XYZ' then it will throw 'Invalid Number' exception because empID in database table is number field.

Most commonly used SQL commands

ALTER TABLE EMPLOYEES ADD AUDIT_ID NUMBER NOT NULL

ALTER TABLE EMPLOYEES DROP COLUMN AUDIT_ID NUMBER NOT NULL


- This query converts the 'String' Date Time object to date object and stores into database, Explains about using to_date() function.

INSERT INTO AUDIT(AUDIT_ID,ENTITY_NAME,AUDIT_KEY,ENTITY_ID,OPERATION,CREATED_BY,CREATION_DATE,LAST_UPDATED_BY,LAST_UPDATE_LOGIN,LAST_UPDATE_DATE) VALUES(23,'HEADERS','AGREEMENT_HEADER_ID','283','INSERT','admin',to_date('20090202121212','yyyyMMddHH24MISS'),'admin','admin',to_date('20090202121212','yyyyMMddHH24MISS'))

// Create DB Sequence

CREATE SEQUENCE  "HR"."EMPLOYEE_ID_SEQ"  MINVALUE 1 MAXVALUE 999999999999999999999999999 INCREMENT BY 1 START WITH 61 CACHE 20 NOORDER  NOCYCLE ;

// Test DB Sequence using SQL Worksheet
select EMPLOYEE_ID_SEQ.nextval from dual

// Get first n Rows from the Database

SELECT * FROM EMPLOYEES WHERE ROWNUM <=5

// Alter the database table column
ALTER TABLE EMPLOYEE MODIFY SALARY NUMBER;

// Left Outer Join

The LEFT JOIN keyword returns all rows from the left table (table1), with the matching rows in the right table (table2). The result is NULL in the right side when there is no match.

SELECT Customers.CustomerName, Orders.OrderID
FROM Customers
LEFT JOIN Orders
ON Customers.CustomerID=Orders.CustomerID
ORDER BY Customers.CustomerName;

SQL Functions to perform IN() clause using ADF Business Components

This blog explains about performing IN() clause with comma separated values in ADF Business components.

Scenario 1 : Get all the employees where employee first name in ('Bob','Rob','Peter','Dan'), Using ADF Business components, pass the comma separated values as a bind parameter and execute the query using the SQL function which I am going to outline in below.

Scenario2 : Same as above, instead of String, 'Number' data type

FM_GN_IN_NUMBER_LIST  - This function accepts comma separated Numbers, delimit the String by ',' and returns array of numbers. So that we can avoid writing query to de


Function 1

// Create num_table type
CREATE TYPE num_table AS TABLE OF NUMBER;

create or replace
FUNCTION     FM_GN_IN_NUMBER_LIST (p_in_list  IN  VARCHAR2)
RETURN num_table
AS
l_tab   num_table := num_table();
l_text  VARCHAR2(32767) := p_in_list || ',';
l_idx   NUMBER;
BEGIN
LOOP
l_idx := INSTR(l_text, ',');
EXIT WHEN NVL(l_idx, 0) = 0;
l_tab.extend;
l_tab(l_tab.last) := to_number(TRIM(SUBSTR(l_text, 1, l_idx - 1)));
l_text := SUBSTR(l_text, l_idx + 1);
END LOOP;

RETURN l_tab;
END;

Function2:

//Create table_of_varchar type as shown below

CREATE TYPE table_of_varchar AS TABLE OF VARCHAR2(2300);

create or replace
FUNCTION     FM_GN_IN_STRING_LIST (p_in_list  IN  VARCHAR2)
RETURN table_of_varchar
AS
l_tab   table_of_varchar := table_of_varchar();
l_text  VARCHAR2(32767) := p_in_list || ',';
l_idx   NUMBER;
BEGIN
LOOP
l_idx := INSTR(l_text, ',');
EXIT WHEN NVL(l_idx, 0) = 0;
l_tab.extend;
l_tab(l_tab.last) := TRIM(SUBSTR(l_text, 1, l_idx - 1));
l_text := SUBSTR(l_text, l_idx + 1);
END LOOP;
RETURN l_tab;
END;

Usage: Below is the example, how to call the function

EmployeeEO.EMP_ID IN (SELECT * FROM TABLE(CAST(fm.fm_gn_in_string_list(:BineEmpID) AS fm.table_of_varchar)))
