Please, don't mix up the concepts "query language" and 
"update language" (or "data manipulation language"). SQL 
comprises both (and, in addition, a "schema definition and 
manipulation language"). The query sublanguage of SQL is 
formed by the SELECT statements, only. 

I know, this is in contrast to, for instance, Microsoft 
jargon, where a data manipulation statement, such as an 
INSERT, is called a "query" (which is stupid)!
