Question

在编写PL / SQL块时，出现以下错误。请让我知道此错误的原因吗？

DECLARE
    TYPE TABLE_NAME IS VARRAY(17) OF VARCHAR(255);
    TABLENAME TABLE_NAME;
    TOTAL INTEGER;
BEGIN
  TABLENAME := TABLE_NAME ('FA_AS_ASSIGNMENTS','FA_PE_PHONES' );
  TOTAL     := TABLENAME.COUNT;
  FOR i IN 1 .. TOTAL
  LOOP
    INSERT
    INTO CUSTOM_ODILOAD_TABLE_COUNT
      (
        TABLE_NAME,
        ROW_COUNT
      )
      VALUES
      (
        TABLENAME(i),
        (SELECT COUNT(*) FROM TABLENAME(i)
        )
      );

  END LOOP;
END;

错误：

ORA-06550：第19行，第40列：PL / SQL：ORA-00907：缺少右括号
  ORA-06550：第10行，第5列：PL / SQL：忽略了SQL语句06550。00000-
  “第％s行，第％s列：\ n％s”
  *原因：通常是PL / SQL编译错误。
  *操作：匿名阻止已完成

您不能为静态查询使用动态表名（即无法对表名进行参数设置）：

DECLARE
TYPE TABLE_NAME IS VARRAY(17) OF VARCHAR(255);
TABLENAME TABLE_NAME;
TOTAL INTEGER;
cnt INTEGER;
BEGIN
  TABLENAME := TABLE_NAME ('FA_AS_ASSIGNMENTS','FA_PE_PHONES' );
  TOTAL     := TABLENAME.COUNT;
  FOR i IN 1 .. TOTAL
  LOOP
     EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM ' || TABLENAME(i) INTO cnt;

    INSERT INTO CUSTOM_ODILOAD_TABLE_COUNT (TABLE_NAME, ROW_COUNT)
      VALUES ( TABLENAME(i), cnt);
  END LOOP;
END;

接收到错误的右括号缺少执行PL / SQL块的错误
