A quick overview of the three core Boolean search operators and Boolean query modifiers: AND, OR, NOT, Asterisk, Parentheses, Quotation Marks. Like XML, XQuery is a case-sensitive language. Keywords in XQuery use lower-case characters and are not reserved—that is, names in XQuery expressions are allowed to be the same as language keywords, except for certain unprefixed function-names listed in A.3 Reserved Function Names.

[Definition: In the data model, a value is always a sequence.]. Creating Microsoft Access Parameter Queries: Most of the queries that you will create in Microsoft Access will have pre entered criteria in the query design grid to select a group of records.
