PLS-00374

Error: PLS-00374: illegal EXIT statement; it must appear inside the loop labeled 'string'

Causa: An EXIT statement need not specify a label. However, if a label is specified (as in EXIT my_label), the EXIT statement must be inside the loop designated by that label.

Acción: Make sure the label name is spelled correctly; if necessary, move the EXIT statement inside the loop to which the label refers.
