Find the Table Name

Ever came across a situation where you know a column name but don't remember the table name. This is the third incident that i forgot the table name and so thought of penning it down.

How I Solved It?
I will just share the queries that will help you get this done. I am sure that would be more than enough.

Query 1:
                             SELECT  *
                             FROM    sys.columns
                             WHERE   name LIKE   '%column_name%'

This query will give you list of object_id and names that has the column name in it Using the object id we can find the object.

Query 2:

                             SELECT  *
                             FROM    sys.objects
                             WHERE   object_id IN  (..., ... , obejct ids from query 1..., ...)


This query will give you the object name and type.  The object of type U are user tables. These tables are list of tables that have the column that we we were looking for

JavaScript Interview Questions

This is a compilations of all the interview questions related to Javascript that i have encountered.  Q: Difference between window.onload and onDocumentReady? A: The onload event does not fire until every last piece of the page is loaded, this includes css and images, which means there’s a huge delay before any code is executed. That isnt what we want. We just want to wait until the DOM is loaded and is able to be manipulated. onDocumentReady allows the programmer to do that. Q:  What is the difference between == and === ? A: The == checks for value equality, but === checks for both type and value. Few examples: "1" == 1; // value evaluation only, yields true "1" === 1; // value and type evaluation, yields false "1" == true; // "1" as boolean is true, value evaluation only, yields true "1" === false; // value and type evaluation, yields false Q: What does “1″+2+5 evaluate to? What about 5 + 2 +...

Do's and Don't SQL

Do's: Writing comments whenever something is not very obvious, as it won’t impact the performance.  (--) for single line  (/*…*/) to mark a section Use proper indentation Use Upper Case for all SQL keywords. SELECT, UPDATE, INSERT, WHERE, INNER JOIN, AND, OR, LIKE. Use BEGIN... END block for multiple statements in conditional code  Use Declare and Set in beginning of Stored procedure Create objects in same database where its relevant table exists otherwise it will reduce network performance. Use PRIMARY key in WHERE condition of UPDATE or DELETE statements as this will avoid error possibilities. If User table references Employee table than the column name used in reference should be UserID where User is table name and ID primary column of User table and UserID is reference column of Employee table. Use select column name instead of select * Use CTE (Common Table Expression); its scope is limited to the next statement in SQL query, instead of...
