If/else if always goes to else statement


If/else if always goes to else statement

may help you . s > 300,000 is a comma expression, equivalent to (s > 300),000. The value of a comma expression is the value of the last one in the list, here 000. Which evaluates as false when converted to bool.
You can write that as
code :
if( s > 300'000 )
if( s > 300000 )
double const k = 1000;
if( s > 300*k )

should help you out Figured the issue and resolved it. It was because of not all tables were created under the same Engine(new tables were under 'InnoDB' because of mysql 5.5 and old tables were under 'MyISAM' because of mysql 5.0).
Here is the detail explanation - http://generics7.blogspot.com/2012/08/unsafe-statement-written-to-binary-log.html

Does that help There is no way to rewrite the sql to not throw that error message. Any sort of order will throw that message as the slave might have different rows then the master. mixed will solve it, as it will only switch to row based replication when a statement is not safe to replicate with statement.
IIf statement and If statement evaluating differently. IIf statement yields incorrect results. Why?

hope this fix your issue Basically, you aren't using IIf correctly here. It doesn't use short circuit evaluation therefore both expressions are evaluated meaning your code is the equivalent to
code :
permissionFlag = False
permissionFlag = True
permissionFlag = IIf(CInt(drow(1)) = 0, False, True)
permissionFlag = CInt(drow(1)) != 0

To fix the issue you can do Finally, the error show exactly what's wrong here. Statement is unsafe because it invokes a trigger or a stored function that inserts into an AUTO_INCREMENT column The error is not in the table itself, the error is in a trigger or procedure that fires when this table get's updated.
Which one is faster? Two fors inside of an if-else statement or a single for statement with an if-else statement?

Hope that helps I would prefer the second construct as it avoids the repetition of the test.
As claimed by others, the compiler might do the transformation. But you don't know for sure, and the cost of duplicating the loop statement isn't significant.
