Preface
The author has written this SQL-help in his free time because
a quick and permanently online SQL-tutorial was needed.
This is only a part of the whole SQL-standart, for more information
about its implementations on different database systems please
contact the software manyfacturers.
The "Standard-SQL", first developed by IBM, was improved by software firms that develop
relational database management systems (RDBMS).
But all of this improvements can not be discussed in an brief help file.
The small table after the command/keyword indicates in some cases, in wich
system this command/keyword is implemented.
