如何使mysqli与SQL语句中的DELIMITER一起使用? [英] How to get mysqli working with DELIMITERs in SQL statements?

问题描述

我正在使用mysqli，现在尝试从SQL代码片段(由MySQL Workbench生成)到数据库中获取视图.

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);

这不起作用.没有错误，该语句似乎只是被忽略了.仅当删除定界符定义(行DELIMITER $$，$$和DELIMITER ;)时，它才有效.

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 ;).

为什么它不起作用?在传递给mysqli函数和方法的SQL语句中如何/应该使用分隔符?

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

Thx

这是帮助我了解这一点的源... http ://zend-framework-community.634137.n4.nabble.com/Problems-changing-the-sql-end-of-statement-delimiter-tp2124060p2124276.html

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不是实际的MySQL语句.

DELIMITER is not an actual MySQL Statement.

我相信这只是某些MySQL客户端已实现的功能，以帮助同时运送一堆sql语句.

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驱动程序未实现此功能.

所以，这应该工作.

$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);

我遇到了相同的问题，使用相同的mysqli驱动程序，multi_query函数(在创建过程时使用定界符)，并从我的SQL中删除了 DELIMITER .

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.
