A real variable with no value specified will be given a value - but usually a very small value that is not precisely zero, and sometimes a value that is not even close to zero. An integer is given the default value 1. This strange behavior is hardly ever a problem, as usually when ...
SERIAL DEFAULT VALUEis a special case. In the definition of an integer column, it is an alias forNOT NULL AUTO_INCREMENT UNIQUE. With one exception, the default value specified in aDEFAULTclause must be a literal constant; it cannot be a function or an expression. This means, for example...

ADEFAULTvalueclause in a data type specification explicitly indicates a default value for a column. Examples: CREATETABLEt1(iINTDEFAULT-1,cVARCHAR(10)DEFAULT'',priceDOUBLE(16,2)DEFAULT0.00); SERIAL DEFAULT VALUEis a special case. In the definition of an integer column, it is an alias forNOT...

The following code example uses both techniques to obtain a default value of 1 if a collection of numeric months is empty. Because the default value for an integer is 0, which does not correspond to any month, the default value must be specified as 1 instead. The first result variable is...
Java provides a richer set of primitive or basic or built-in data types than other languages like C and C++. There are eight built-in types supported by Java to support integer, floating-point, character, and boolean values. All primitive or basic data types hold numeric data that is ...
