Using Session Variable in the Column Level Security

Question

My Question -
1. I created an initialization block with initialization string by calling a new session variable CTP_ID_LIST in the sql command, given appropriate database connections and when I exit out of Block, and chosen Row-wise initialization. I do not see a new session variable created under variables list. Why does this happen? Please help me on this.

Hi,
This happens when you select Row-wise Initialization.
The row-wise initialization feature allows you to create session variables dynamically and set their values when a session begins. The names and values of the session variables reside in an external database that you access through a connection pool. The variables receive their values from the initialization string that you type in the Initialization Block dialog box.
You can also use the row-wise initialization feature to initialize a variable with a list of values. You can then use the SQL IN operator to test for values in a specified list.
Example: Using the table values in the previous example, you would type the following SQL statement for the initialization string:
select 'LIST_OF_USERS', USERID
from RW_SESSION_VARS
where NAME='STATUS' and VALUE='FULL-TIME'
This SQL statement populates the variable LIST_OF_USERS with a list, separated by colons, of the values JOHN and JANE; for example, JOHN:JANE. You can then use this variable in a filter, as shown in the following WHERE clause:
where TABLE.USER_NAME = valueof(NQ_SESSION.LIST_OF_USERS)
The variable LIST_OF_USERS contains a list of values, that is, one or more values. This logical WHERE clause expands into a physical IN clause, as shown in the following statement:
where TABLE.USER_NAME in ('JOHN', 'JANE')
