mysql - SQL 导入 PostgreSQL 8.4.20 失败并出现语法错误

Question

我使用现有 Mysql 数据库中的数据导出了 SQL 文件。现在我正在尝试将其导入 PostgrSQL 数据库中。

我尝试使用 phpPgAdmin 导入字段。我执行了这个 SQL，因为我已经创建了我的表。

INSERT INTO `categories` (`id`, `name`, `created_at`, `updated_at`, `ancestry`, `ancestry_depth`, `priority`) VALUES
(1, 'Treileri', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(2, 'Kravas automašīnas', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(3, 'Teleskopiskie iekrāvēji', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(4, 'Ekskavatori', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(5, 'Iekrāvēji', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(6, 'Pacēlāji', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(7, 'Elektroiekārtas', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(8, 'Ģeneratori', '2014-09-24 17:45:02', '2014-09-24 17:45:02', '7', 1, NULL),
(9, 'Strāvas kārbas', '2014-09-24 17:45:02', '2014-09-24 17:45:02', '7', 1, NULL),
(10, 'Aprīkojums', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(11, 'Vibro blietes', '2014-09-24 17:45:03', '2014-09-24 17:45:03', '10', 1, NULL),

(13, 'Vinčas', '2014-09-24 17:45:03', '2014-09-24 17:45:03', '10', 1, NULL),
(14, 'Gāzes sildītāji', '2014-09-24 17:45:03', '2014-09-24 17:45:03', '10', 1, NULL),
(15, 'Plātņu satvērēji', '2014-09-24 17:45:03', '2014-09-24 17:45:03', '10', 1, NULL),
(16, 'Celtniecības sastatnes', '2014-09-24 17:45:03', '2014-09-24 17:45:03', NULL, 0, NULL),
(17, 'Citi', '2014-09-24 17:45:03', '2014-09-24 17:45:03', NULL, 0, NULL);

错误:

SQL 错误:

ERROR:  syntax error at or near "INTO"
LINE 1: SELECT COUNT(*) AS total FROM (INSERT INTO `categories` (`id...
                                              ^

我检查了 SQL 有效性 here并且没有发现任何错误。我不明白问题出在哪里？

也许 PostgreSQL 版本有问题？

根据您的建议，我将代码更改为:

INSERT INTO "categories" ("id", "name", "created_at", "updated_at", "ancestry", "ancestry_depth", "priority") VALUES
(1, "Treileri", '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(2, "Kravas automašīnas", '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(3, "Teleskopiskie iekrāvēji", '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),

(7, "Elektroiekārtas", '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(8, "Ģeneratori", '2014-09-24 17:45:02', '2014-09-24 17:45:02', '7', 1, NULL),
(9, "Strāvas kārbas", '2014-09-24 17:45:02', '2014-09-24 17:45:02', '7', 1, NULL),
(10, "Aprīkojums", '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(11, "Vibro blietes", '2014-09-24 17:45:03', '2014-09-24 17:45:03', '10', 1, NULL),

(14, "Gāzes sildītāji", '2014-09-24 17:45:03', '2014-09-24 17:45:03', '10', 1, NULL),
(15, "Plātņu satvērēji", '2014-09-24 17:45:03', '2014-09-24 17:45:03', '10', 1, NULL),
(16, "Celtniecības sastatnes", '2014-09-24 17:45:03', '2014-09-24 17:45:03', NULL, 0, NULL),
(17, "Citi", '2014-09-24 17:45:03', '2014-09-24 17:45:03', NULL, 0, NULL);

还是同样的错误。

谢谢。

字 rune 字需要用单引号括起来，而不是双引号。双引号用于标识符。 "Treileri" 是一个标识符(例如列名)，'Treileri' 是一个字 rune 字。

因此您需要将值的所有双引号替换为单引号:

INSERT INTO "categories" ("id", "name", "created_at", "updated_at", "ancestry", "ancestry_depth", "priority") VALUES
(1, 'Treileri', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
(2, 'Kravas automašīnas', '2014-09-24 17:45:02', '2014-09-24 17:45:02', NULL, 0, NULL),
.....

有关标识符和文字的更多详细信息可以在手册中找到:

如果这是新安装，则不应使用不再维护(=支持)的版本。 8.4确实老了。对于新安装，您应该选择 9.3 或 9.4
