Weird - MySQL's SQL::Sqlexception Is Not Caught by Its Type, But Is Caught as Std::Exception and Cast Back Successfully

How to avoid the divide by zero error in SQL?

In order to avoid a "Division by zero" error we have programmed it like this:

Select Case when divisor=0 then null
Else dividend / divisor
End ,,,

But here is a much nicer way of doing it:

Select dividend / NULLIF(divisor, 0) ...

Now the only problem is to remember the NullIf bit, if I use the "/" key.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax error Hibernate 4

OK I've found solution; we still can use 'order' keyword as column name like this:

@Column(name = "`order`", length = 10, precision =0) 
private int order;

Thanks Ghost and Dave Newton for your care.

PDOException SQLSTATE[HY000] [2002] No such file or directory

The error message indicates that a MySQL connection via socket is tried (which is not supported).

In the context of Laravel (artisan), you probably want to use a different / the correct environment. Eg: php artisan migrate --env=production (or whatever environment). See here.

error, string or binary data would be truncated when trying to insert

From @gmmastros's answer

Whenever you see the message....

string or binary data would be truncated

Think to yourself... The field is NOT big enough to hold my data.

Check the table structure for the customers table. I think you'll find that the length of one or more fields is NOT big enough to hold the data you are trying to insert. For example, if the Phone field is a varchar(8) field, and you try to put 11 characters in to it, you will get this error.

java.lang.IllegalAccessError: tried to access method

You are almost certainly using a different version of the class at runtime to the one you expect. In particular, the runtime class would be different to the one you've compiled against (else this would have caused a compile-time error) - has that method ever been private? Do you have old versions of the classes/jars on your system anywhere?

As the javadocs for IllegalAccessError state,

Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.

I'd definitely look at your classpath and check whether it holds any surprises.
