prepareOn(); // When activated will use prepare statements for all shortcut SQL Methods calls.
prepareOff(); // When off shortcut SQL Methods calls will use vendors escape routine instead. This is the default behavior.

// The variadic ...$whereConditions, and ...$conditions parameters,
//  represent the following global functions.
// They are comparison expressions returning an array with the given arguments,
//  the last arguments of _AND, _OR, _NOT, _andNOT will combine expressions
eq('column', $value, _AND), // combine next expression
neq('column', $value, _OR), // will combine next expression again
ne('column', $value), // the default is _AND so will combine next expression

lte('column', $value)

// The above should be used within the where( ...$whereConditions) clause
// $value will protected by either using escape or prepare statement

// wrap the following around a group of the above comparison
// expressions within the where( ...$whereConditions) clause
