将ojdbc驱动程序升级到ojdbc7后，camel-sql组件在使用命名参数执行查询时开始创建问题。
提供了在执行期间失败的简单SQL查询。并非所有查询都失败，但只有少数失败。
SELECT some_id FROM app_schema.app_store_table WHERE store_id =：＃storeId and source =：#source;
在数据库端验证用户名可以通过app_schema访问该对象，并尝试创建PUBLIC同义词，但没有运气。
根据我的理解，它在尝试获取SqlProducer.java中的参数计数时失败 - ＆gt; process（） - ＆gt; execute（） - ＆gt; ps.getParameterMetaData（）
jdbcTemplate.execute(statementCreator, new PreparedStatementCallback<Map<?, ?>>() {
public Map<?, ?> doInPreparedStatement(PreparedStatement ps) throws SQLException {
int expected = parametersCount > 0 ? parametersCount : ps.getParameterMetaData().getParameterCount();
进一步调试从ojdbc7驱动程序中发现以下错误。它确认ojdbc7驱动程序无法正确解析查询。在下面的示例中，schema_name和table_name之间的。[DOT]在执行之前被ojdbc驱动程序替换。

使用以下命令
可以轻松复制-- example for .[DOT] getting replaced between schema_name and table_name. Refer Parameter SQL.
