SQLite JDBC 驱动没有实现

Question

我已经使用sqlitejdbc-v056.jar 成功地为 SQLite 数据库创建了 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>

当我在 IE 和 Firefox 中浏览到我的 .cfm 页面时，我收到错误消息：

SQLite JDBC 驱动没有实现

C:/Inetpub/wwwroot/intra/SmartTV/UnassignedTickets/Tickets.cfm 出现错误：第 204 行

202 :
203：
204：
205：选择
206：身份证，

SQL SELECT id、summary、status、created_at、assigned_to FROM 门票 WHERE status = 'open' AND assignment_to IS NULL ORDER BY created_at DESC DATASOURCE Spiceworks 资源：

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

更新：

我的 .jar 文件位于 C:\ColdFusion10\cfusion\lib\ 和 C:\ColdFusion10\cfusion\wwwroot\WEB-INF\lib 下。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
• 驱动类：org.sqlite.JDBC
• 驱动名称：sqlite-jdbc-3.7.15-M1.jar
• 用户名：<user>
• 密码：<password>

按照 cmets 中的建议，我尝试了更简单的语句：

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

...和different driver versions

• sqllite-jdbc4-3.8.2-SNAPSHOT.jar
• sqlite-jdbc-3.7.15-M1.jar

但仍然出现同样的错误。

Answer 1

我认为最初的错误正是它所说的。数据源调用了您正在使用的驱动程序未实现的方法。特别是org.sqlite.jdbc3.JDBC3Statement 的execute(..) 方法。 The source for this driver 表明该方法什么也不做。它只是抛出您看到的错误消息。

但是我认为您的类路径中有另一个版本的 SQLite 驱动程序 jar。您发布的sqlitejdbc-v056.jar 不会导致该错误，因为它甚至不包含JDBC3Statement 类。可能发生的情况是 CF 正在加载另一个其他版本的驱动程序（即在您的类路径中）。

在我的测试中，sqlitejdbc-v056.jar 在 CF10 上运行良好。在再次添加该 jar 之前，请确保您已从 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，您将继续收到该错误消息。

为确保您已删除 所有 个 jar，请在重新启动后尝试创建主类的实例。如果下面的行抛出“找不到类”错误，您就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. 创建空数据库C:/temp/sqlite/products.db
2. 已将sqlitejdbc-v056.jar 下载到C:\ColdFusion10\cfusion\wwwroot\WEB-INF\lib
3. 重启CF
4. 创建了“其他”DSN
5. DSN 设置
   • DS 名称：SQLite
   • JDBC URL：jdbc:sqlite:C:/temp/sqlite/products.db
   • 驱动类：org.sqlite.JDBC
