For the latest documentation updates see the OpenEdge Product Documentation Overview page on PSDN: http://communities.progress.com/pcom/docs/DOC-16074. The audience of this book is composed of two groups: • Database administrators will use the book to: – Create and maintain databases – Create, modify, and revoke user privileges – Tune database performance – Perform installation and setup of servers and clients • Application developers will use the book to: – Manage database connections and set up data sources – Create database queries – Tune database queries – Develop application business logic Part I, SQL Reference OpenEdge SQL Statements Describes the purpose and syntax of each OpenEdge SQL statement. A sample is provided for each statement. OpenEdge SQL Functions Describes the purpose and syntax of each OpenEdge SQL function. A sample is provided for each function.
OpenEdge SQL Reserved Words Preface Provides a list of words that have special syntactic meaning to OpenEdge SQL and cannot be used as identifiers for constants, variables, cursors, types, tables, records, subprograms or packages. OpenEdge SQL Error Messages Provides a list of error messages generated by the various components of OpenEdge SQL. OpenEdge SQL System Limits Provides a list of the maximum sizes for various attributes of the OpenEdge SQL database environment, and for elements of SQL queries addressed to this environment. OpenEdge SQL System Catalog Tables Provides a set of system tables for storing information about tables, columns, indexes, constraints, and privileges. This chapter describes those system catalog tables. Data Type Compatibility Addresses compatibility issues when using OpenEdge SQL and earlier versions of the database. OpenEdge SQL Language Elements Describes Standard SQL language elements that are common to OpenEdge SQL. OpenEdge SQL Elements and Statements in Backus Naur Form Presents OpenEdge SQL elements and statements in Backus Naur Form. Compliance with Industry Standards Addresses compatibility issues when using OpenEdge SQL and earlier versions of its database. Syntax for ABL Attributes Lists and describes SQL keywords to use with statements that allow you to define ABL attributes for tables and columns. Part II, JDBC Reference Java Class Reference Provides information on OpenEdge SQL Java classes and methods. JDBC Conformance Notes Provides information on mapping between JDBC and other data types and return values for database metadata. Preface–3
