I HAVE TWO TABLE

TABLE_ENTITY
ENTITY_CODE     ENTITY_NAME

SR	        SR INFO SOLUTION
DP	        DIGITAL PLANET
TABLE_USER
NAME           ENTITY_CODE

KESHRI	        SR
EHTE	        DP
REZA	        SR DP
Want query like, if TABLE_USER.ENTITY_CODE = TABLE_ENTITY.ENTITY_CODE then show the value into :LIST_ITEM
When i query for KESHRI it's showing SR INFO SOLUTION and for EHTE it's showing DIGITAL PLANET
But when query for REZA it's showing nothing, i want SR INFO SOLUTION & DIGITAL PLANET into :LIST_ITEM

HOW TO DO THIS???

Best Practice is to store single value in each column.
Worst Practice stores more than 1 value in single column.

In other words, TABLE_USER should look like
KESHRI   SR
EHTE     DP
REZA     SR
REZA     DP

Actually TABLE_USER having more than 1000 records and 50 column and TABLE_ENTITY is more than 20 and 10 column
columns having not null values and child records etc...
result, i have to create numbers of row for that

its better if i enter TABLE_USER.ENTITY_CODE like 'DP SR XX YY ZZ ...'

so that's why i need this type of validation...

No, it is not better. If TABLE_USER contains many columns (how are we supposed to know that? We know only what you tell us), then remove ENTITY_CODE from current TABLE_USER table and create a new table, for example TABLE_USER_ENTITY which would look as I described in my previous message.

created 2 views
CREATE OR REPLACE VIEW VIEW_CALL AS
SELECT DISTINCT

       SUBSTR(VIEW_CALL.NO_SPACE,5,2) AS CCC
  FROM VIEW_CALL
and then
DECLARE

				END LOOP;
			END LOOP;
		END LOOP;
	END;
1. how to merge both views into 1
2. how to merge ADD_LIST_ELEMENT into 1 so that i use ORDER BY CLAUSE
3. how to set one default value in list item using WHERE CLAUSE OR OTHER example...

code's are well executing but i don't know it's in proper channel or not

TEST CASE
CREATE TABLE USER_MAST(
USER_CODE VARCHAR(8) NOT NULL,
PASSWORD VARCHAR(20) NOT NULL,
ENTITY VARCHAR(50));

CREATE TABLE ENTITY_MAST(
ENTITY_CODE VARCHAR(2) NOT NULL,
ENTITY_NAME VARCHAR(50));

INSERT INTO USER_MAST VALUES ('MSRDBA','12345','SR DP XP');
INSERT INTO USER_MAST VALUES ('ACC-RN','123','SR');
INSERT INTO USER_MAST VALUES ('DP-KT','XYZ','DP XP');

INSERT INTO ENTITY_MAST VALUES ('SR','SR INFO SOLUTION');
INSERT INTO ENTITY_MAST VALUES ('DP','DIGITAL PLANET');
INSERT INTO ENTITY_MAST VALUES ('XP','XEROX POINT');
SELECT * FROM USER_MAST;
SELECT * FROM ENTITY_MAST;

I don't see the purpose of VIEW_CALL1 as VIEW_CALL seems to be VIEW_CALL with additional columns. If you really must combine them, make a third one and union them together, setting the 3 additional columns to NULL.

And if you insist on two or three views, then having distinct in more than one of them is unnecessary.

You can't work out how to merge 2 views when one of them only queries the other?
Replace the from of VIEW_CALL1 with the whole select of VIEW_CALL - i.e. nest it so you don't have to do the replace 4 times.

As for merging the cursors - OR is a wonderful thing.

And I don't know what you think you're doing with rownum there but what you've got will give rownum of 1 for each query if you use the login MSRDBA.

You should really read what other people tell you. Cookiemonster gave the instructions; how come you didn't follow them?

(SELECT DISTINCT (SUBSTR(X, 3, 2))
       FROM (SELECT DISTINCT (REPLACE(ENTITY, ' ')) AS X
       FROM USER_MAST
       WHERE USER_CODE IN ('MSRDBA'))
       WHERE USER_CODE IN ('MSRDBA')) AS XXX

MERGED VIEW INTO 1

HOW I SELECT DEFAULT/ INITIAL VALUE IN LIST_ITEM
BUT NOT USING ITEM_PROPERTY INITIAL VALUE
BECAUSE INITIAL VALUE IS DIFFERENT FOR EACH USER

You don't need to specify user_code twice, and if that's the view I'm not sure why you're specifying it at all - it won't work for other users.

You probably don't want to set initial value programatically - you'd have to do it in when-new-record-instance and doing so would immediately change the record status to insert - meaning forms thinks there's changes that need saving and will prompt the users if they try to leave the record in any way. If you default it in when-validate-record or pre-insert (so as part of the save process), you'll avoid that problem.

Thank you i solved my problem
SELECT DISTINCT ROWNUM RN_SR, ENTITY_CODE ||' - '|| ENTITY_NAME AS ENTITY_SHOW
FROM ENTITY_MAST, USER_MAST
WHERE USER_CODE = :LOGIN_USER_CODE
AND :LOGIN_PASSWORD = PASSWORD
AND ENTITY_CODE = (SELECT DISTINCT (SUBSTR(SR, 0, 2))
FROM (SELECT DISTINCT (REPLACE(ENTITY, ' ')) AS SR
FROM USER_MAST
WHERE USER_CODE = :LOGIN_USER_CODE));

Pretty sure it can simply be this:
SELECT DISTINCT ROWNUM RN_SR, ENTITY_CODE ||' - '|| ENTITY_NAME AS ENTITY_SHOW
FROM ENTITY_MAST, USER_MAST
WHERE USER_CODE = :LOGIN_USER_CODE
AND :LOGIN_PASSWORD = PASSWORD
AND ENTITY_CODE = SUBSTR(REPLACE(ENTITY, ' '), 0, 2);

The main query is already selecting from user_mast, so having a sub-query to get the same user_mast record is pointless.
The above only does the equivalent of GRP_SR, what about the other 2?

That first distinct is pointless as well, When you select rownum every row ends up being distinct because of it.
