PLS-00103:遇到以下其中一项时遇到符号:

Question

似乎没问题但是我得到了例外,请纠正我.

declare
    var_number number;

begin
    var_number := 10;

    if var_number > 100 then
        dbms_output.put_line(var_number||' is greater than 100');
    elseif var_number < 100 then
        dbms_output.put_line(var_number||' is less than 100');
    else
        dbms_output.put_line(var_number||' is equal to 100');
    end if;

end;

例外:

ORA-06550: line 8, column 8:
PLS-00103: Encountered the symbol "VAR_NUMBER" when expecting one of the following:
    := . ( @ % ;
ORA-06550: line 13, column 4:
PLS-00103: Encountered the symbol ";" when expecting one of the following:
    if

Answer 1

Oracle PL/SQL的关键字是"ELSIF"(没有额外的"E"),而不是ELSEIF(是的,令人困惑和愚蠢)

declare
    var_number number;
begin
    var_number := 10;
    if var_number > 100 then
       dbms_output.put_line(var_number||' is greater than 100');
    elsif var_number < 100 then
       dbms_output.put_line(var_number||' is less than 100');
    else
       dbms_output.put_line(var_number||' is equal to 100');
    end if;
end;

Answer 2

IF 语句具有以下形式PL/SQL：

IF THEN
IF THEN ELSE
IF THEN ELSIF

您所使用elseif的 PL/SQL 术语是错误的。需要将其替换为ELSIF.

所以你的代码应该像这样。

    declare
        var_number number;
    begin
        var_number := 10;
        if var_number > 100 then
           dbms_output.put_line(var_number ||' is greater than 100');
--elseif should be replaced with elsif
        elsif var_number < 100 then
           dbms_output.put_line(var_number ||' is less than 100');
        else
           dbms_output.put_line(var_number ||' is equal to 100');
        end if;
    end;
