Question

    DECLARE DBName VARCHAR(100); ApplicationURL VARCHAR(100);

BEGIN
select NAME into DBName FROM v$database;  

  IF DBName = 'WAMDEV' THEN ApplicationURL := 'http://srpwam10:9080/maximo';
      ELSIF  DBName ='WAMDEVPJ' THEN ApplicationURL := 'http://srpwam10:9080/maximo';
      ELSIF  DBName = 'WAMTST' THEN ApplicationURL := 'http://wamtest/maximo'
      ELSIF  DBName = 'WAMTSTPJ' THEN ApplicationURL := 'http://wamtest/maximo'
      ELSIF  DBName = 'WAMQA' THEN ApplicationURL := 'http://wamqa/maximo'
      ELSIF  DBName = 'WAMQAPJ'  THEN ApplicationURL := 'http://wamqa/maximo'
      ELSE  DBName = 'WAMP' THEN ApplicationURL := 'http://wam/maximo'
    END IF ;
    DBMS_OUTPUT.PUT_LINE(ApplicationURL)
    END

它给了我错误： ORA-06550：第9行，第7栏： PLS-00103：遇到以下任何一种情况时遇到符号“ELSIF”：

＆安培; = - +; ＆LT; /＆gt;在in是mod余数而不是rem ＆LT;＆GT;或！=或〜=＆gt; =＆lt; =＆lt;＆gt;或者喜欢喜欢2 like | likec之间的|| multiset成员submultiset
1. 00000 - “行％s，列％s：\ n％s” *原因：通常是PL / SQL编译错误。

添加了您缺少的半冒号

DECLARE
  DBNAME         VARCHAR(100);
  APPLICATIONURL VARCHAR(100);

BEGIN
  SELECT NAME INTO DBNAME FROM V$DATABASE;

  IF DBNAME = 'WAMDEV' THEN
    APPLICATIONURL := 'http://srpwam10:9080/maximo';
  ELSIF DBNAME = 'WAMDEVPJ' THEN
    APPLICATIONURL := 'http://srpwam10:9080/maximo';
  ELSIF DBNAME = 'WAMTST' THEN
    APPLICATIONURL := 'http://wamtest/maximo';
  ELSIF DBNAME = 'WAMTSTPJ' THEN
    APPLICATIONURL := 'http://wamtest/maximo';
  ELSIF DBNAME = 'WAMQA' THEN
    APPLICATIONURL := 'http://wamqa/maximo';
  ELSIF DBNAME = 'WAMQAPJ' THEN
    APPLICATIONURL := 'http://wamqa/maximo';
  ELSE
    DBNAME := 'WAMP';
    APPLICATIONURL := 'http://wam/maximo';
  END IF;
  DBMS_OUTPUT.PUT_LINE(APPLICATIONURL);
END;

也可以使用CASE声明，在某些人看来，它看起来更干净。

IF ELSIF有什么问题？
