  • What is Interoperability Testing?

    Interoperability Testing can validate that two products work together and yet neither may be in compliance with the specification. This often happens when sets of two products are tested in a pair-wise manner but the sets are not tested with each other. This situation occurs for various reasons - foremost being the lack of universal test cases and unclear testing procedures. The principal risk in this...

    Advantages of views:

    1. View the data without storing the data into the object.

    2. Restict the view of a table i.e. can hide some of columns in the tables.

    3. Join two or more tables and show it as one object to user.

    4. Restict the access of a table so that nobody can insert the rows into the table.


    1. Can not use DML operations on this.

    2. When table is dropped view becomes inactive.. it depends on the table objects.

    3. It is an object, so it occupies space.

    Pls. add , if I miss any of them.

  • What is difference between Co-related sub query and nested sub query?

    Co-related sub query is one in which inner query is evaluated only once and from that result outer query is evaluated.Nested query is one in which Inner query is evaluated for multiple times for gatting one row of that outer query.ex. Query used with IN() clause is Co-related query. Query used with = operator is Nested query

    • Member Since Sep-2007 | May 3rd, 2008

    1. Function is mainly used in the case where it must return a value. Where as a procedure may or may not return a value or may return more than one value using the OUT parameter.
    2. Function can be called from SQL statements where as procedure can not be called from the sql statements

    3. Functions are normally used for computations where as procedures are normally used for executing business logic.

    4. You can have DML (insert,update, delete) statements in a function. But, you cannot call such a function in a SQL query.

    5. Function returns 1 value only. Procedure can return multiple values (max 1024).

    6.Stored Procedure: supports deferred name resolution. Example while writing a stored procedure that uses table named tabl1 and tabl2 etc..but actually not exists in database is allowed only in during creation but runtime throws error Function wont support deferred name resolution.

    7.Stored procedure returns always integer value by default zero. where as function return type could be scalar or table or table values

    8. Stored procedure is precompiled execution plan where as functions are not.
    9.A procedure may modify an object where a function can only return a value The RETURN statement immediately completes the execution of a subprogram and returns control to the caller.

    Answer posted by Radhika on 2005-05-23 17:50:13: The purpose of testing can be quality assurance, verification and validation, or reliability estimation.
