我每次尝试在 pl/sql 块中进行选择或任何操作时都使用MariaDB 10.5.6-MariaDBwith ，然后它会显示“函数不存在”。InnoDB 10.5.6我究竟做错了什么？在使用 pl/sql 之前是否需要获取库？这是没有意义的。

这有效（在开始/结束之外），我得到了结果：94

select count(1) from information_schema.all_plugins;

这不起作用

BEGIN
    select count(1) from information_schema.all_plugins;
END;
/

错误：

Error starting at line : 1 in command -
BEGIN
    select count(1) from information_schema.all_plugins;
END;
Error report -
FUNCTION count does not exist

这都不起作用：

BEGIN
    declare rowCount decimal;
    select count(1) into @rowCount from information_schema.all_plugins;
END;
/

错误：

Error starting at line : 1 in command -
BEGIN
    declare rowCount decimal;
    select count(1) into @rowCount from information_schema.all_plugins;
END;
Error report -
FUNCTION count does not exist

这也不起作用

BEGIN
    select 'hello world';
END;
/

错误：

Error starting at line : 1 in command -
BEGIN
    select 'hello world';
END;
Error report -
FUNCTION 'hello does not exist
