如何执行PL/SQL表语句

亲爱的朋友们，我把这些语句存储在一个表中，我需要执行它们来接收结果。如何执行PL/SQL表语句

DECODE (to_char((SELECT s1.streettypename FROM autodesk.smstreets s0, autodesk.smstreettypes s1 where s0.streettypeid = s1.streettypeid(+) AND s0.streetantiq=0 AND s0.streetid=COD_VIA)) ||''|| to_char((SELECT s0.streetname FROM autodesk.smstreets s0, autodesk.smstreettypes s1 where s0.streettypeid = s1.streettypeid(+) AND s0.streetantiq=0 AND s0.streetid=COD_VIA)) ||''|| to_char(NRO_VIA) ||''|| to_char(NRO_PUERTA),'', 'No Disponible', to_char((SELECT s1.streettypename FROM autodesk.smstreets s0, autodesk.smstreettypes s1 where s0.streettypeid = s1.streettypeid(+) AND s0.streetantiq=0 AND s0.streetid=COD_VIA)) ||' '|| to_char((SELECT s0.streetname FROM autodesk.smstreets s0, autodesk.smstreettypes s1 where s0.streettypeid = s1.streettypeid(+) AND s0.streetantiq=0 AND s0.streetid=COD_VIA)) ||' '|| to_char(NRO_VIA) ||' '|| to_char(NRO_PUERTA))',DECODE (to_char((SELECT s1.streettypename FROM autodesk.smstreets s0, autodesk.smstreettypes s1 where s0.streettypeid = s1.streettypeid(+) AND s0.streetantiq=0 AND s0.streetid=COD_VIA)) ||''|| to_char((SELECT s0.streetname FROM autodesk.smstreets s0, autodesk.smstreettypes s1 where s0.streettypeid = s1.streettypeid(+) AND s0.streetantiq=0 AND s0.streetid=COD_VIA)) ||''|| to_char(NRO_VIA) ||''|| to_char(NRO_PUERTA),'', 'No Disponible', to_char((SELECT s1.streettypename FROM autodesk.smstreets s0, autodesk.smstreettypes s1 where s0.streettypeid = s1.streettypeid(+) AND s0.streetantiq=0 AND s0.streetid=COD_VIA)) ||' '|| to_char((SELECT s0.streetname FROM autodesk.smstreets s0, autodesk.smstreettypes s1 where s0.streettypeid = s1.streettypeid(+) AND s0.streetantiq=0 AND s0.streetid=COD_VIA)) ||' '|| to_char(NRO_VIA) ||' '|| to_char(NRO_PUERTA)) FROM cliente WHERE NRO_CLIENTE='104631'

欢迎来到Stack Overflow，@miMescua。要获得最佳答案，您将有助于编辑您的问题以提供更多信息。具体而言，您希望得到的结果，输入数据的样本，以及您当前的尝试未正确执行的方式。请查看：https：//stackoverflow.com/help/how-to-ask – Degan

如果，因为它的出现，这些都是（在开始减关键字select，并在许多语法错误）返回1行2列的所有SELECT语句，那么你可以这样做：

declare 
    l_sql long; 
    l_col1 long; 
    l_col2 long; 
begin 
    for r_sql in (select statement from my_table) loop 
    dbms_output.put_line('Statement: '||r_sql.statement); 
    l_sql := 'select '||r_sql.statement; 
    begin 
     execute immediate l_sql into l_col1, l_col2; 
     dbms_output.put_line('returned: '||l_col1||','||l_col2); 
    exception 
     when no_data_found then 
     -- take appropriate action 
     when too_many_rows then ... 
     -- take appropriate action 
    end; 
    end loop; 
end;

但是，只有当数据中的语法错误得到修复时，它才会起作用 - 例如

to_char(NRO_CLIENTE)',to_char(NRO_CLIENTE) FROM cliente WHERE NRO_CLIENTE='104631'

...有to_char(NRO_CLIENTE)后一个假“，这将导致语句失败运行时。
