     Je to standardne aj bez uvodzoviek, definicia SQL-92 hovori:

<update statement: searched> ::=
    UPDATE <table name>
      SET <set clause list>
      [ WHERE <search condition> ]
...
<set clause list> ::=
    <set clause> [ { <comma> <set clause> }... ]

<set clause> ::=
    <object column> <equals operator> <update source>
