Question

DBMS输出未显示

DECLARE
COUNT1 NUMBER;


BEGIN
    SELECT COUNT(*)
    INTO COUNT1
    FROM PROCESSPART
    WHERE DIV = '1'
     AND BK = '0G'
     AND BK_YR = '19';
  DBMS_OUTPUT.PUT_LINE('PROCESSPART RECORDS IN GEN5 FOR LOC 1, BK 0G, BK_YR 2019');
  DBMS_OUTPUT.PUT_LINE(COUNT1);

  END;

我已经在SQL Developer中打开了DBMS输出，并且该窗口在那里，已连接到DB。但是，当我运行该块时，成功完成后窗口中什么也没有出现。

在您的语句使用下面的指令之前（如OldProgrammmer所说）并一起运行它们：

SET serveroutput ON

DECLARE
COUNT1 NUMBER;


BEGIN
    SELECT COUNT(*)
    INTO COUNT1
    FROM PROCESSPART
    WHERE DIV = '1'
     AND BK = '0G'
     AND BK_YR = '19';
  DBMS_OUTPUT.PUT_LINE('PROCESSPART RECORDS IN GEN5 FOR LOC 1, BK 0G, BK_YR 2019');
  DBMS_OUTPUT.PUT_LINE(COUNT1);

END;
