shopware onetonone relationship error :General error: 1215 Cannot add foreign key constraint

Question

我正在尝试使用这两个查询将 2 Table 添加到我的数据库中，但是在添加 OnetoOne 关系时出现此错误，我正在使用 shopware 作为执行此查询的框架。错误说：

SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint"

CREATE TABLE `texdata_productFields` (
`id` BINARY(16) NOT NULL,
`product_id` BINARY(16) NOT NULL,
`product_version_id` BINARY(16) NOT NULL,
`form_number` INT(11) NOT NULL,
`quality_number` INT(11) NOT NULL,
`color_number` INT(11) NOT NULL,
`color_group` INT(11) NULL,

`care_symbols` VARCHAR(255) NULL,
`created_at` DATETIME(3) NOT NULL,

CREATE TABLE `texdata_productFields_translation` (

KEY `fk.texdata_productFields_translation.language_id` (`language_id`),
CONSTRAINT `fk.texdata_productFields_translation.texdata_productFields_id` FOREIGN KEY (`texdata_productFields_id`) REFERENCES `texdata_productFields` (`id`) ON DELETE SET NULL ON UPDATE CASCADE,

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

语言 Table 是默认值 table，这是构建它的查询：

CREATE TABLE `language` (
`id` BINARY(16) NOT NULL,
`parent_id` BINARY(16) NULL,
`locale_id` BINARY(16) NOT NULL,
`translation_code_id` BINARY(16) NULL,
`name` VARCHAR(255) NOT NULL,
`custom_fields` JSON NULL,
`created_at` DATETIME(3) NOT NULL,
`updated_at` DATETIME(3) NULL,
PRIMARY KEY (`id`),
CONSTRAINT `json.language.custom_fields` CHECK (JSON_VALID(`custom_fields`)),
KEY `fk.language.parent_id` (`parent_id`),
KEY `fk.language.locale_id` (`locale_id`),
KEY `fk.language.translation_code_id` (`translation_code_id`),
CONSTRAINT `fk.language.parent_id` FOREIGN KEY (`parent_id`) REFERENCES `language` (`id`) ON DELETE SET NULL ON UPDATE CASCADE,
CONSTRAINT `fk.language.locale_id` FOREIGN KEY (`locale_id`) REFERENCES `locale` (`id`) ON DELETE SET NULL ON UPDATE CASCADE,
CONSTRAINT `fk.language.translation_code_id` FOREIGN KEY (`translation_code_id`) REFERENCES `locale` (`id`) ON DELETE SET NULL ON UPDATE CASCADE
 ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

Answer 1

您可能需要确保已在子 table 到 可为空的列 .

如果你设置

ON DELETE SET NULL

到你的外键然后它不会允许你将字段设置为

NOT NULL
