Question

我尝试使用SQLite数据库在Pentaho数据集成中创建表输入步骤。连接似乎很好......

Connection to database [Volp_2] is OK.
Hostname       : C:\Users\Aluno\Apps\VOLP\BD\volp.db
Port           : -1
Database name  : *****

...但是通过表输入步骤预览前1000行

我做错了什么？任何人都可以帮助我吗？

Answer 1

这个错误看起来就是原因：

select nome from palavras

因为它抱怨该表不存在......

您确定表格拼写正确还是与数据库名称相关联？如果直接连接sqlite3并运行查询，此查询是否有效？

Answer 2

此内容已在 https://gobansaor.wordpress.com/2006/12/18/sqlite-jdbc-and-kettle-pentaho-data-integration-etl/

以下是删除文章的步骤：

1. Within SPOON, make a new connection using for example a Table Input step.
2. In the General tab, pick “Generic database” from the list of connection types.
3. Pick “Native(JDBC)” from the Method of Access list.
No further information required on this tab, go to the Generic tab.
4. In the URL field, enter “jdbc:sqlite:c:\mydata\mydatabase.db” where c:\mydata\mydatabase.db is the SQLite database you wish to connect to.
5. In the Driver class field, enter “org.sqlite.JDBC”.

以前，包含JDBC类的jar文件必须保存到data-integration \ lib文件夹中。

无法使用Pentaho Data Integration在SQLite数据库中进行选择：java.sql.SQLException：ResultSet已关闭
