<dd>Identifies one or more locator variables that must be declared in accordance
|

|
with the rules for declaring locator variables. The locator variable type

must be a binary large object locator, a character large object locator, or

|
a double-byte character large object locator.

<p>The <span class="italic">variable</span> must currently have a locator assigned to it. That is, a locator

must have been assigned during this unit of work (by a CALL, FETCH, SELECT
|

INTO, assignment statement, SET variable, or VALUES INTO statement) and must

not subsequently have been freed (by a FREE LOCATOR statement); otherwise,

<p>If more than one locator variable is specified
