Я создаю эту процедуру географически.Когда я работаю, он выдает ошибку

call geographical("VESTAS",null,null,null,null,null,null,null,null); ОШИБКА 1064 (42000): у вас ошибка в синтаксисе SQL;проверьте руководство, соответствующее вашей версии сервера MySQL, чтобы найти правильный синтаксис для использования рядом с 'NULL' в строке 1

. Я также написал другую процедуру, в которой нет оператора в кавычках, он дает мне пустой набор.

Answer 1

Нет никаких причин использовать подготовленные операторы в вашей хранимой процедуре.Это затрудняет написание / чтение / сопровождение процедуры и делает ее более подверженной ошибкам.

Использование в процедуре прямого SQL, чтобы вы также избежали проблем при объединении значений NULL.

Answer 2

Вы заключаете ноль в строку, это приведет к нулю.например, есть CONCAT ('' ', appl_name2,' "'), для которого appl_name2 имеет значение null, вместо« null »(строка) это приведет к нулю.

Вы можете попробовать это, чтобы лучше понять:

select concat('first',null,'second');

Я предлагаю вам использовать функцию COALESCE, например:

select concat('first',coalesce(appl_name2,'NULL','notnull'),'second');
