DDL Keywords and Reserved Words
If the string contains quotation marks, you must enter each quotation mark twice to
distinguish the quotation mark character from the string delimiter. You can use either
single or double quotation marks as string delimiters. Examples of DDL strings follow:
"C00"
"12.650"
"Enter a 2-character state code."
"M<[phone]>"
"Use quotes "" "" before and after the name."
'Use quotes '' '' to delimit a string.'
'alpha-string'
DDL Keywords and Reserved Words
DDL keywords are words with a specific meaning to DDL. DDL reserved words are a
subset of the keywords and must not be used as data names in DDL statements.
DDL Keywords
A keyword has a specific syntactical meaning when placed at a keyword position within
a statement. Keywords must be spelled exactly as shown in this manual.
To distinguish keywords from variable names in this manual, keywords are always
capitalized in the formal syntax descriptions. When you specify keywords in DDL input,
however, you do not need to capitalize them; they are not case sensitive.
DDL keywords cannot be defined as constant names.
These are the DDL keywords:
