In addition to the prefixes in the above list, this document uses the prefix err to represent the namespace URI http: This namespace prefix is not predeclared and its use in this document is not normative. It also uses the namespace URI http: Element nodes have a property called in-scope namespaces.
The in-scope namespaces property of an element node is a set of namespace bindings, each of which associates a namespace prefix with a URI. XQuery does not support the namespace axis and does not represent namespace bindings in the form of nodes.
An application that needs to create a set of namespace nodes to represent these bindings can do so using the following code. The expression context for a given expression consists of all the information that can affect the result of the expression. The module context for a given module consists of all the information that is accessible to top-level expressions in the module.
This information is organized into two categories called the static context and the dynamic context. The static context of an expression is the information that is available during static analysis of the expression, prior to its evaluation.
The individual components of the static context are described below. Rules governing the initialization and alteration of these components can be found in C.
This component must be set by all host languages that include XPath 3. XQuery sets the value of this component to false. This is a mapping from prefix to namespace URI that defines all the namespaces that are known during static processing of a given expression.
Note the difference between in-scope namespaceswhich is a dynamic property of an element node, and statically known namespaceswhich is a static property of an expression. Some namespaces are predefined; additional namespaces can be added to the statically known namespaces by namespace declarationsschema importsor module imports in a Prologby a module declarationand by namespace declaration attributes in direct element constructors.
The namespace URI, if present, is used for any unprefixed QName appearing in a position where an element or type name is expected. The namespace URI, if present, is used for any unprefixed QName appearing in a position where a function name is expected.
This is a generic term for all the element declarations, attribute declarations, and schema type definitions that are in scope during static analysis of an expression. Each schema type definition is identified either by an expanded QName for a named type or by an implementation-dependent type identifier for an anonymous type.
The in-scope schema types include the predefined schema types described in 2. If the Schema Aware Feature is supported, in-scope schema types also include all type definitions found in imported schemas.
Each element declaration is identified either by an expanded QName for a top-level element declaration or by an implementation-dependent element identifier for a local element declaration. If the Schema Aware Feature is supported, in-scope element declarations include all element declarations found in imported schemas.
Substitution groups are defined in [XML Schema 1. Informally, the substitution group headed by a given element called the head element consists of the set of elements that can be substituted for the head element without affecting the outcome of schema validation.How to write contain query for msaccess database My table have column value ' CHOPE PARMA TERA ' my search keyword in PARMA.

2 Basics The basic building block of XQuery is the expression, which is a string of characters; the version of Unicode to be used is alphabetnyc.com language provides several kinds of expressions which may be constructed from keywords, symbols, and operands.
The apostrophe, or single quote, is a special character in SQL that specifies the beginning and end of string data.
This means that to use it as part of your literal string data you need to escape the special character. With a single quote this is typically accomplished by doubling your quote.

How to put this query? I want to export the DATASET as SQL INSERT statement, so I can't use this in SQL-PLUS. sql oracle plsql toad. You can escape the ampersand character by . I keep on forgetting this and coming back to it again! I think the best answer is a combination of the responses provided so far.
Firstly, & is the variable prefix in sqlplus/sqldeveloper, hence the problem - when it appears, it is expected to be part of a variable name.
Having run both queries on a SQL Server instance, I can confirm the first query was fastest in my case. The query with the LIKE keyword showed a clustered index scan. The CONTAINS also had a clustered index scan with additional operators for the full text match and a merge join.
