問題描述

我正在使用 mysqli，現在嘗試從 SQL 代碼片段(由 MySQL Workbench 生成)獲取視圖到數據庫中.

I'm using mysqli and trying now to get a view from an SQL code snippet (generated by MySQL Workbench) into a database.

$query = <<<QUERY
DROP VIEW IF EXISTS `myview` ;
SHOW WARNINGS;
DROP TABLE IF EXISTS `myview`;
SHOW WARNINGS;
DELIMITER $$
CREATE OR REPLACE VIEW `myview` AS

...view definition...

$$
DELIMITER ;

;
SHOW WARNINGS;

SET SQL_MODE=@OLD_SQL_MODE;
SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS;
SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS;
QUERY;

$result = mysqli_multi_query($dbConnection, $query);

這行不通.沒有錯誤，該語句似乎只是被忽略了.它僅適用于，如果我刪除分隔符定義(行 DELIMITER $$、$$ 和 DELIMITER ;).

This doen't work. No errors, the statement seems just to be ignored. It only works, if I remove the delimiter definitions (lines DELIMITER $$, $$, and DELIMITER ;).

為什么它不起作用?在傳遞給 mysqli 函數和方法的 SQL 語句中使用分隔符可以/應該做什么?

Why is it not working? What can/should I do to use delimiters in SQL statements passed to mysqli functions and methods?

謝謝

This is the source that helped me understand this... http://zend-framework-community.634137.n4.nabble.com/Problems-changing-the-sql-end-of-statement-delimiter-tp2124060p2124276.html

DELIMITER 不是真正的 MySQL 語句.

DELIMITER is not an actual MySQL Statement.

我相信這只是一些 MySQL 客戶端實現的東西，以幫助同時傳送一堆 sql 語句.

I believe it is just something that some MySQL clients have implemented to help shipping a bunch of sql statements at the same time.

mysqli 驅動程序沒有實現這個功能.

所以，這應該可行.

$query = <<<QUERY
DROP VIEW IF EXISTS `myview` ;
SHOW WARNINGS;
DROP TABLE IF EXISTS `myview`;
SHOW WARNINGS;

CREATE OR REPLACE VIEW `myview` AS

...view definition...

;
SHOW WARNINGS;

SET SQL_MODE=@OLD_SQL_MODE;
SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS;
SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS;
QUERY;

$result = mysqli_multi_query($dbConnection, $query);

我遇到了同樣的問題，使用相同的 mysqli 驅動程序，使用 multi_query 函數(在創建過程時使用分隔符)并從我的 SQL 中刪除 DELIMITER 工作.

I ran into the same problem, with the same mysqli driver, with multi_query function (using delimiters while creating procedures) and removing the DELIMITER from my SQL worked.
