+   The user must have <code class="literal">EXECUTE</code> privilege on the procedure in

+   To call a function (not a procedure), use <code class="command">SELECT</code> instead.
+  </p><p>
+   If <code class="command">CALL</code> is executed in a transaction block, then the
+   called procedure cannot execute transaction control statements.
+   Transaction control statements are only allowed if <code class="command">CALL</code>
+   is executed in its own transaction.
