A package is an object that contains control structures (called sections) used to execute SQL statements. Packages are produced during program preparation. The sections created for static SQL can be thought of as the bound or operational form of SQL statements. The sections created for dynamic SQL can be thought of as placeholder control structures which are used at execution time. All sections in a package are derived from the SQL statements embedded in a single source file. See the Embedded SQL Programming Guide for more information on packages.
