Oracle update statement not updating

Several statements can be grouped together to form a single transaction.Data Definition Language (DDL) commands perform an implicit commit, which also confirms all outstanding DML changes in the current session.They are not permanent until they are confirmed using the statement.Once committed, the only way you can revert a change is to issue a new DML statement to alter the data.--DROP TABLE employees PURGE; --DROP TABLE departments PURGE; CREATE TABLE departments ( department_id NUMBER(2) CONSTRAINT departments_pk PRIMARY KEY, department_name VARCHAR2(14), location VARCHAR2(13) ); INSERT INTO departments VALUES (10,'ACCOUNTING','NEW YORK'); INSERT INTO departments VALUES (20,'RESEARCH','DALLAS'); INSERT INTO departments VALUES (30,'SALES','CHICAGO'); INSERT INTO departments VALUES (40,'OPERATIONS','BOSTON'); COMMIT; CREATE TABLE employees ( employee_id NUMBER(4) CONSTRAINT employees_pk PRIMARY KEY, employee_name VARCHAR2(10), job VARCHAR2(9), manager_id NUMBER(4), hiredate DATE, salary NUMBER(7,2), commission NUMBER(7,2), department_id NUMBER(2) CONSTRAINT emp_department_id_fk REFERENCES departments(department_id) ); INSERT INTO employees VALUES (7369,'SMITH','CLERK',7902,to_date('','dd-mm-yyyy'),800, NULL,20); INSERT INTO employees VALUES (7499,'ALLEN','SALESMAN',7698,to_date('20-2-1981','dd-mm-yyyy'),1600,300,30); INSERT INTO employees VALUES (7521,'WARD','SALESMAN',7698,to_date('22-2-1981','dd-mm-yyyy'),1250,500,30); INSERT INTO employees VALUES (7566,'JONES','MANAGER',7839,to_date('2-4-1981','dd-mm-yyyy'),2975, NULL,20); INSERT INTO employees VALUES (7654,'MARTIN','SALESMAN',7698,to_date('28-9-1981','dd-mm-yyyy'),1250,1400,30); INSERT INTO employees VALUES (7698,'BLAKE','MANAGER',7839,to_date('1-5-1981','dd-mm-yyyy'),2850, NULL,30); INSERT INTO employees VALUES (7782,'CLARK','MANAGER',7839,to_date('9-6-1981','dd-mm-yyyy'),2450, NULL,10); INSERT INTO employees VALUES (7788,'SCOTT','ANALYST',7566,to_date('13-JUL-87','dd-mm-rr')-85,3000, NULL,20); INSERT INTO employees VALUES (7839,'KING','PRESIDENT', NULL,to_date('','dd-mm-yyyy'),5000, NULL,10); INSERT INTO employees VALUES (7844,'TURNER','SALESMAN',7698,to_date('8-9-1981','dd-mm-yyyy'),1500,0,30); INSERT INTO employees VALUES (7876,'ADAMS','CLERK',7788,to_date('13-JUL-87', 'dd-mm-rr')-51,1100, NULL,20); INSERT INTO employees VALUES (7900,'JAMES','CLERK',7698,to_date('3-12-1981','dd-mm-yyyy'),950, NULL,30); INSERT INTO employees VALUES (7902,'FORD','ANALYST',7566,to_date('3-12-1981','dd-mm-yyyy'),3000, NULL,20); INSERT INTO employees VALUES (7934,'MILLER','CLERK',7782,to_date('23-1-1982','dd-mm-yyyy'),1300, NULL,10); COMMIT; These tables are a variant of the EMP and DEPT tables from the SCOTT schema.

But when i tried to use an update query (very simple update - a table with 2 columns and 10 rows and even first column being a primary key) the update step runs for long time. in our case we are using user defined functions and stored procedure to update our data(this logic is purly different than your scenario). Earlier I downloaded ojdbc14and orai18and placed inside ..\data-integration\libext\JDBC folder.

I am able to connect with oracle database and able to execute 'SELECT' query thru table input step. Thanks, Thana we are facing similar issue but not with 10 records, problem with lakhs of records in our scenario.
