運行示例SQL時出現問題

Question

錯誤：

ORA-06550: line1, column 22: PLS-00103 Encountered the symbol "end-of-file" when expecting one of the following: * & = - + .......

PL / SQL塊：

DECLARE v_c number :=0;
   BEGIN
      SELECT COUNT(*) into v_c from all_sequences where sequence_name='TEST_SEQ' and   sequence_owner='test';
      IF v_c = 1 THEN
         execute immediate 'DROP SEQUENCE test.TEST_SEQ';
      END IF;
   END;
/

Answer 1

我從您的帖子中復制了代碼，並在SQLDeveloper和SQLPlus中運行了它們，都沒有問題：

已連接到：Oracle Database 11g版本11.2.0.3.0-生產

prompt> DECLARE v_c number :=0;                        
  2     BEGIN
  3        SELECT COUNT(*) into v_c from all_sequences where sequence_name='TEST_SEQ' and sequence_owner='test';
  4        IF v_c = 1 THEN
  5           execute immediate 'DROP SEQUENCE test.TEST_SEQ';
  6        END IF;
  7     END;
  8  /

PL/SQL procedure successfully completed.

您正在使用什么工具？ 我最好的建議是在SQLPlus中嘗試一下，如果仍然有錯誤，請向我們顯示會話的全文。

Answer 2

您只執行第一行，而不執行整個PL / SQL塊。

DECLARE v_c number :=0
/

導致：

DECLARE v_c number :=0
                 *
ERROR at line 1:
ORA-06550: line 1, column 22:
PLS-00103: Encountered the symbol "end-of-file" when expecting one of the
following:
* & = - + ; < / > at in is mod remainder not rem

就像其他人建議的那樣，請在SQLPlus中嘗試此操作。
