php 联合选择不同的问题

Question

我提交了这两个文件:

• sample_annotation.txt
• sample_synteny.txt

我在下一页上收到以下错误:

304501820180500000018.304501820180500000018<br><br>select distinct org1,org2 from '.304501820180500000018.'_synteny union select distinct org1,org2 from '.304501820180500000018.'_synteny<br><br>

Invalid query: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''.304501820180500000018.'_synteny union select distinct org1,org2 from '.3045018' at line 1

## Return the JSON object

我创建了一个 docker-compose.yml ，可以通过以下方式运行:

git clone https://github.com/mictadlo/mGSV-docker.git
docker-compose up --build

该服务可以通过localhost访问，PhpMyAdmin可以通过localhost:8183访问

我错过了什么？

提前谢谢

尝试在 Mysql phpmyadmin 中独立运行这两个查询

select distinct org1,org2 from '.304342020180200000016.'_synteny

select distinct org1,org2 from '.304342020180200000016.'_synteny

据我所知，您的查询似乎是正确的，因为联合需要相同的列数和相同的数据类型。

为什么你的联合查询中的表名是相同的。
