Other syntax segments
These topics describe syntax segments, which are language elements, such as database object names or optimizer directives, that appear as a subdiagram reference in the syntax diagrams of some SQL or SPL statements.
Most segments that can occur in only one statement are described in SQL statements or SPL statements within the description of the statement. For the sake of clarity, ease of use, and comprehensive treatment, however, most segments that can occur in various SQL or SPL statements, and that are not data types nor expressions, are discussed separately here.
The previous chapter described the syntax segments that specify data types and expressions. This chapter describes additional syntax segments that are neither data types, expressions, nor complete SQL statements or SPL statements. These segments are referenced in various syntax diagrams that appear in SQL statements and in other chapters of this document.
