没有由SQLite JDBC驱动程序实现

Question

我已成功使用sqlitejdbc-v056.jar.创建了一个到SQLite数据库的ColdFusion数据源.然后我将此查询添加到我的.cfm页面

<cfquery name="qry" datasource="Spiceworks">
SELECT
id AS Ticket_Number,
summary AS Summary,
status AS Status,
created_at AS Created_At,
assigned_to AS Assigned_to

FROM tickets
WHERE status = 'open' AND assigned_to IS NULL
ORDER BY Created_At DESC   
</cfquery>

当我浏览IE和Firefox中的.cfm页面时,出现错误:

没有由SQLite JDBC驱动程序实现

错误发生在C:/Inetpub/wwwroot/intra/SmartTV/UnassignedTickets/Tickets.cfm:第204行

202:
203:
204:
205:SELECT
206:id,

SQL SELECT id,summary,status,created_at,assigned_to FROM tickets WHERE status ='open'AND assigned_to IS NULL ORDER BY created_at DESC DATASOURCE Spiceworks Resources:

Check the ColdFusion documentation to verify that you are using the correct syntax.

更新:

我C:\ColdFusion10\cfusion\lib\和.jar文件下有和C:\ColdFusion10\cfusion\wwwroot\WEB-INF\lib.在ColdFusion数据源中:

• CF数据源名称:Spiceworks
• JDBC URL:jdbc:sqlite:\ spiceworks\C $\Program Files\Spiceworks\db\spiceworks_prod.db
• 驱动程序类:org.sqlite.JDBC
• 驱动程序名称:sqlite-jdbc-3.7.15-M1.jar
• 用户名: <user>
• 密码: <password>

正如评论中所建议的那样,我尝试了更简单的陈述:

• SELECT * FROM tickets
• SELECT id, summary, status, assigned_to FROM tickets

......和不同的驱动程序版本

• sqllite-jdbc4-3.8.2-SNAPSHOT.jar
• sqlite的-JDBC-3.7.15-M1.jar

但仍然有同样的错误.

Answer 1

我认为原来的错误的意思正是它所说的。数据源调用了您正在使用的驱动程序未实现的方法。具体execute(..)方法是org.sqlite.jdbc3.JDBC3Statement. 该驱动程序的源代码表明该方法不执行任何操作。它只是抛出您所看到的错误消息。

不过我认为你的类路径中有另一个版本的 SQLite 驱动程序 jar。您发布的内容sqlitejdbc-v056.jar不会导致该错误，因为它甚至不包含类JDBC3Statement。可能发生的情况是 CF 正在加载另一个版本的驱动程序（位于您的类路径中）。

在我的测试中，sqlitejdbc-v056.jarCF10 工作得很好。在再次添加该 jar 之前，请确保已从 CF 类路径中删除了SQLLite jar 的所有版本，然后重新启动 CF。否则，CF 仍会自动加载它们，并且您将继续收到该错误消息。

为了确保您已删除所有jar，重新启动后，尝试创建主类的实例。如果下面的行抛出“未找到类”错误，则您知道已成功将它们全部删除。完成此操作后，请继续重新安装sqlitejdbc-v056.jar.

<cfset obj = createObject("java", "org.sqlite.JDBC")>
If you see this text, you still have a version of the jar in your class path.

这对我有用：

1. 创建了空数据库C:/temp/sqlite/products.db
2. 下载sqlitejdbc-v056.jar到C:\ColdFusion10\cfusion\wwwroot\WEB-INF\lib
3. 重新启动CF
4. 创建“其他”DSN
5. DSN 设置
   • DS名称：SQLite
   • JDBC URL：jdbc:sqlite:C:/temp/sqlite/products.db
   • 驱动程序类：org.sqlite.JDBC
