Collection data for multiple clients and you structured the database so that data for each client was in a For repository variable initialization blocks, when you open a repository in online mode, the value shown in the Default initialization string field of the Initialization Block dialog is the current value of that variable as known to the Oracle BI Server. A repository variable has a single value at any point in time. Names for all variables should be unique. For example, using the table values in the previous example, you would type the following SQL statement for the initialization string: 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).

When a user belongs to multiple roles, include the role names in the same column, separated by semicolons (for example, RoleA;RoleB;RoleC). Debugging The values of dynamic repository variables are set by queries defined in the Default initialization string field of the Initialization Block dialog. Create a session variable called MVCOUNTRY____SEBL, making sure to include four underscores between the variable name and the source name. You can also use the row-wise initialization option to initialize a variable with a list of values.
