导入csv文件时，mysql输入中的mysql无效列数 [英] mysql Invalid column count in CSV input while importing csv file

问题描述

我在数据库中有一个名为locations的表，其中包含2列(id会自动递增，location)，并且我有一个csv包含1列，看起来像:

I have a table in the database called locations which contains 2 columns(id which is auto incremented , location) , And I have a csv contains 1 column looks like :

当我尝试将该文件导入到locations表时，出现此错误invalid column count in CSV input on line 1.

When I try to import that file to locations table , I get this error invalid column count in CSV input on line 1.

我也尝试过CSV using LOAD DATA，但是我得到了:MySQL returned an empty result set (i.e. zero rows)

Also I tried CSV using LOAD DATA but I get this : MySQL returned an empty result set (i.e. zero rows)

推荐答案

如果您的计算机支持Java，请使用以下解决方案

If Java is supported in your machine, Use below solution

要做的简单配置是

<?xml version="1.0" encoding="UTF-8"?>
<config>
  <connections>
      <jdbc name="mysql">
          <driver>com.mysql.jdbc.Driver</driver>
          <url>jdbc:mysql://localhost:3306/test1</url>
          <user>root</user>
          <password></password>
      </jdbc>
  </connections>
  <component-flow>
      <execute name="file2table" enabled="true">
          <migrate>
              <source>
                  <file delimiter="," header="false" path="D:/test_source.csv"/>
              </source>
              <destination>
                  <table connection="mysql">locations</table>
              </destination>
              <mapping>
                  <column source="1" destination="location" />
              </mapping>
          </migrate>
      </execute>
  </component-flow>
</config>

如果您有兴趣，可以通过Java代码实现.

If you are interested, Same can be achieved by Java code.

Source source = new File("D:/test_source.csv", ',', false);
        Destination destination = new Table("locations", new JDBCConnection("com.mysql.jdbc.Driver", "jdbc:mysql://localhost:3306/test1", "root", ""));
        List<Mapping> mapping = new ArrayList<>();
        mapping.add(new Mapping("1", "location", null));
        Component component = new MigrateExecutor(source, destination, mapping);
        component.execute();
