【问题描述】*：达梦执行动态SQL时，传递的参数会被解析为字段，我想要的结果是解析成字符串，以下是执行的SQL
DECLARE
QYK VARCHAR(50);
c1 CURSOR;
BEGIN
OPEN c1 FOR SELECT distinct owner from all_tables where owner like '%QYK_%';
LOOP
FETCH c1 INTO QYK;
EXIT WHEN c1%NOTFOUND;
execute immediate 'select X,Y,'||QYK||'as QYK from TB1';
END LOOP;
CLOSE c1;
END;
执行后会报一个错误，没有XXX这个字段
DECLARE
QYK VARCHAR(50);
c1 CURSOR;
BEGIN
OPEN c1 FOR SELECT distinct owner from all_tables where owner like '%QYK_%';
LOOP
FETCH c1 INTO QYK;
EXIT WHEN c1%NOTFOUND;
execute immediate 'select X,Y,'''||QYK||'''as QYK from TB1';
END LOOP;
CLOSE c1;
END;
