String assignments
There are two types of string assignments.
- Storage assignment is when a value is assigned to a column, a parameter of a function or procedure, or a transition variable.
- Retrieval assignment is when a value is assigned to a variable (but not a parameter or transition variable).1

assigning to an SQL-variable or SQL-parameter and the standards option
is specified, storage assignment rules apply. For information about
the standards option, see Standards compliance.
