In SQL , the code TRUNCATE TABLE code statement is a Data Definition Language DDL operation that marks the extents of a table for deallocation empty for reuse . The result of this operation quickly removes all data from a Table database table , typically bypassing a number of integrity enforcing mechanisms. It was officially introduced in the SQL 2008 standard. The code TRUNCATE TABLE mytable code statement is logically though not physically equivalent to the code Delete SQL DELETE FROM mytable code statement without a code Where SQL WHERE code clause . The following characteristics distinguish code TRUNCATE TABLE code from code DELETE code In the Oracle Database , code TRUNCATE code is implicitly preceded and followed by a Commit data management commit operation. This may also be the case in MySQL , depending on the chosen storage engine. Typically, code TRUNCATE TABLE code quickly deletes all records in a table by deallocating the data pages used by the table. This reduces the resource overhead of Transaction log logging the deletions, as well as the number of Lock database locks acquired ...

The SQL XML , or XML Related Specifications , extension to the SQL standard is defined by ISO IEC 9075 14 see SQL . SQL XML specifies SQL based extensions for using XML in conjunction with SQL. The XML data type is introduced, as well as several routines, functions, and XML to SQL data type mappings to support manipulation and storage of XML in a SQL database . The SQL XML specification includes functions to construct XML data. These functions allow the user to construct new XML elements or attributes with values e.g. from relational tables. Other functions such as XMLCONCAT or XMLAGG can be used to combine small XML fragments into larger ones. The list of available construction functions includes XMLELEMENT XMLATTRIBUTES XMLFOREST XMLCONCAT XMLNAMESPACES XMLCOMMENT XMLPI XMLDOCUMENT XMLAGG etc. SQL XML also defines functions which allow the user to embed XQuery expressions in SQL statements. These functions include XMLQUERY XMLTABLE While XMLQUERY returns values of type XML, the function XMLTABLE can take XML data as input and produce a relational table as output. Predicates on XML data, such as search conditions, can be expressed with the XMLEXISTS predicate, typically in the WHERE clause of a SQL statement.
