In other words, it returns the result and stop evaluating other conditions as soon as it finds a match. Simple CASE example. Let's take a look at the customers table in the sample database.

I am not sure. that is why i am asking whether we can use CASE statement in the SELECT query to dynamically change the condition in the WHERE clause based on some values fetched from other query.

Now if @usageunitName='kg', i have to select unittypeid,typename from the master_unittype. In this syntax, Db2 compares the expression in the CASE clause with each expression (expression_1, expression_2, ) in the WHEN clause sequentially from top to bottom.. Db2 returns the corresponding result in the THEN clause (result_1, result_2, ) if it finds a match (expression = expression1, expression = expression2).Db2 immediately stops searching once it finds a match It is different from the SQL standard. Nevertheless I think it is = worth the change as the primary use case for the clause will be slight adju= stments to the original schema rather than rewriting the table completely. = /span> Example SQL WHERE clauses: Avoid CASE, use Boolean logic.

Hence, we have completed our first part of SQL Clauses Tutorial. In this, we discussed 3 main types of clause in SQL that is - WITH Clause, SELECT Clause, and FROM Clause. Further, in FROM Clause, we saw from clause hints, nested table reference, texttable and XMLtable. Also, we learned the syntax and syntax rules of SQL Clauses There's a ton of articles out there on how to implement a case statement in a WHERE clause but couldn't find one on how to implement a CASE statement in a WHERE clause that gives you the ability to use a NOT IN or IN filter. I guess the only way to explain this is to use an example, and I am fully aware that the use of this may not be the best practice and is most likely required because. www.msdn.microsoft.co
