CAN/CSA-ISO/IEC 4/9/9075 PDF

1 Scope

This part of International Standard ISO/IEC 9075 specifies the syntax and semantics of a database language for declaring and maintaining persistent database language routines in SQL-server modules.

The database language for externally-invoked procedures andSQL-invoked routine>s includes: - The specification of statements to direct the flow of control. - The assignment of the result of expressions to variables and parameters. - The specification of condition handlers that allow SQL-invoked routines to deal with various conditions that arise during their execution. Preface

Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).

This Standard supersedes CAN/CSA-ISO/IEC 9075-4-04 (adoption of ISO/IEC 9075-4:2003). At the time of publication, ISO/IEC 9075-4:2008 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC.

This part of International Standard ISO/IEC 9075 specifies the syntax and semantics of a database language for declaring and maintaining persistent database language routines in SQL-server modules. The database language for externally-invoked procedures and SQL-invoked routine>s includes:
- The specification of statements to direct the flow of control.
- The assignment of the result of expressions to variables and parameters.
- The specification of condition handlers that allow SQL-invoked routines to deal with various conditions that arise during their execution.
- The specification of statements to signal and resignal conditions.
- The declaration of standing SQL-server cursors.
- The declaration of local variables. It also includes the definition of the Information Schema tables that contain schema information pertaining to SQL-server modules and SQL-invoked routines.
