与union选择不同的php问题

Question

我提交了这两个文件：

• sample_annotation.txt
• sample_synteny.txt

我在下一页出现了以下错误：

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

Whole query: select distinct org1,org2 from '.304501820180500000018.'_synteny union select distinct org1,org2 from '.304501820180500000018.'_synteny[]

mGSV/lib/data.php如下所示，导致上述错误：

## Return the JSON object

我创建了一个doker-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

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

我错过了什么？

提前谢谢

Answer 1

尝试在Mysql phpmyadmin中独立运行两个查询

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

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

因为我看到你的查询似乎是正确的，因为union需要相同数量的列和相同的数据类型。

为什么联合查询中的表名都是相同的。
