This International Standard defines the data structures and basic operations on SQL-data. It provides functional capabilities for creating, accessing, maintaining, controlling, and protecting SQL-data.
Note: The framework for this International Standard is described by the Reference Model of Data Management (ISO/IEC DIS 10032:1991).
This International Standard specifies the syntax and semantics of a database language
- for specifying and modifying the structure and the integrity constraints of SQL-data,
- for declaring and invoking operations on SQL-data and cursors, and
- for declaring database language procedures and embedding them into a standard programming language.
It also specifies an Information Schema that describes the structure and the integrity constraints of SQL-data.
This International Standard
- provides a vehicle for portability of data definitions and compilation units between SQL-implementations,
- provides a vehicle for interconnection of SQL-implementations,
- specifies syntax for embedding SQL-statements in a compilation unit that otherwise conforms to the standard for a particular programming language. It defines how an equivalent compilation unit may be derived that conforms to the particular programming language standard. In that equivalent compilation unit, each embedded SQL-statement has been replaced by statements that invoke a database language procedure that contains the SQL-statement, and
- specifies syntax for direct invocation of SQL-statements.
This International Standard does not define the method or time of binding between any of:
- database management system components,
- SQL data definition declarations,
- SQL procedures, or
- compilation units, including those containing embedded SQL.
Implementations of this International Standard may exist in environments that also support application programming languages, end-user query languages, report generator systems, data dictionary systems, program library systems, and distributed communication systems, as well as various tools for database design, data administration, and performance optimization.
