<p>This statement can only be embedded in an application program. It cannot

<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,
|
|
an error is returned.</p>
|
|
<p>If more than one locator variable is specified
|
|
and an error occurs on one of the locators, no locators will be freed.</p>
