What happens when there's insufficient memory to throw an OutOfMemoryError?
...n OutOfMemoryError.
So, it does a computation in advance before doing allocation of the object.
What happens is that the JVM tries to allocate memory for an object in the memory called Permanent Generation region (or PermSpace). If allocation fails (even after the JVM invokes the Garbage Col...
Catching java.lang.OutOfMemoryError?
... to do so).
In general, the OutOfMemoryError occurs due to a block memory allocation that cannot be satisfied with the remaining resources of the heap.
When the Error is thrown the heap contains the same amount of allocated objects as before the unsuccessful allocation and now is the time to drop ...

... data, and then use our own database tool which allows keyword parsing and token based replacement in scripts. It also ensures scripts are only applied once.
Why?
We need to support installations on SQL Server 2000, 2005 and 2008, and there are changes to data types between versions, e.g. 2005+ ...

How can I reliably determine the type of a variable that is declared using var at design time?

Whenever the parser meets this token (which could be anywhere) it knows that this is the signal to send back all the information it has back to the editor. It does this using a longjmp be...
