I'm researching the LAST_INSERT_ID command for MYSQL. from what i have seen - I can save it as a 'variable' as @variable = LAST_INSERT_ID(); Question: What is the difference between @THIS_VARIABLE and $that_variable (with a dollar $ sign)?? I cannot find ANY examples/tutorials that say we can save it as a $variable. -- Gordon.
