this one helps. The case goes as following: You have a Boolean property called FullScreenEnabled. You enter some method, and the code within this method is executed iff FullScreenEnabled is true. Which of the 2 approaches below do you use in your everyday programming:
code :
private void MyMethod(bool arg){
   if(arg)
       return;
   //do stuff
};

I wish did fix the issue. It is a SQL language construct, which evaluates always to true (because 1 is always equal to 1). It is used mostly when generating dynamic SQL queries for developer`s convenience.

around this issue The default place MySQL will look for a column in a subquery is the table from which you are querying so
code :
SELECT COUNT(1) 
FROM tblScheduled
WHERE tblScheduled.SubscriptionID = SubscriptionID AND tblScheduled.DateScheduled = RealWorldVisitDate
SELECT COUNT(1) 
FROM tblScheduled
WHERE tblScheduled.SubscriptionID = tblScheduled.SubscriptionID AND tblScheduled.DateScheduled = RealWorldVisitDate
SELECT COUNT(1) 
FROM tblScheduled 
WHERE tblScheduled.DateScheduled = RealWorldVisitDate

This might help you These queries are different from each other, they are asking for different things and returning different results.
code :
MATCH (p:Person)-[:WROTE]->(m:Movie)
 WHERE NOT exists( (p)-[:DIRECTED]->() )
 RETURN p.name, m.title
MATCH (p:Person)-[:WROTE]->(m:Movie)
 WHERE NOT exists( (p)-[:DIRECTED]->(m) )
 RETURN p.name, m.title
