The labeling rules are basically same as for COBOL. These rules apply to labels:

(a) SQL reserved words

• Both uppercase and lowercase letters can be used
• Uppercase and lowercase letters can be mixed

(b) Host names

• Labels that begin with SQL cannot be used
• Blanks can be entered following a colon within a host name
• Host names are not case-sensitive
• Uppercase and lowercase letters can be mixed

Embedded variables, indicator variables, and branching destination labels must be named in accordance with the COBOL labeling rules.

The following labels, which have the external attribute, cannot be used:

• Labels that begin with the uppercase letters SQL
• Labels that begin with the lowercase letter p_
• Labels that begin with the lowercase letters pd

1. Members of an object cannot be used as embedded variables.
2. An object method cannot be specified in the WHENEVER statement.
3. An SQL statement cannot be coded in a class definition.

All other coding rules are the same as for COBOL. For details, see 7.3.1(2) SQL coding rules.
