Question

我尝试使用ODI和自定义LKM将数据从SQL Server导出到Azure。 LKM中的步骤如下：

在“加载数据”步骤中，我使用SQLServerBulkCopy，但是当KM尝试执行 bulkCopy.setDestinationTableName（destinationTable）;

它收到错误：

ODI-1228：在目标MICROSOFT_SQL_SERVER连接BJE-Azure-TEST上，任务SrcSet0（正在加载）失败。原因：java.sql.SQLException：[FMWGEN] [SQLServer JDBC驱动程序] [SQLServer]'/'附近的语法不正确。在weblogic.jdbc.sqlserverbase.ddb_.b（未知来源）在weblogic.jdbc.sqlserverbase.ddb_.a（未知来源）在weblogic.jdbc.sqlserverbase.ddb9.b（未知来源）在weblogic.jdbc.sqlserverbase.ddb9.a（未知来源）在weblogic.jdbc.sqlserver.tds.ddr.v（未知来源）在weblogic.jdbc.sqlserver.tds.ddr.a（未知来源）在weblogic.jdbc.sqlserver.tds.ddq.a（未知来源）在weblogic.jdbc.sqlserver.tds.ddr.a（未知来源）在weblogic.jdbc.sqlserver.ddj.m（未知来源）在weblogic.jdbc.sqlserverbase.ddel.e（未知来源）在weblogic.jdbc.sqlserverbase.ddel.a（未知来源）在weblogic.jdbc.sqlserverbase.ddde.a（未知来源）在weblogic.jdbc.sqlserverbase.ddel.v（未知来源）在weblogic.jdbc.sqlserverbase.ddel.r（未知来源）在weblogic.jdbc.sqlserverbase.ddde.execute（未知来源）在oracle.odi.runtime.agent.execution.sql.SQLCommand.execute（SQLCommand.java:163）在oracle.odi.runtime.agent.execution.sql.SQLExecutor.execute（SQLExecutor.java:102）在oracle.odi.runtime.agent.execution.sql.SQLExecutor.execute（SQLExecutor.java:1）在oracle.odi.runtime.agent.execution.TaskExecutionHandler.handleTask（TaskExecutionHandler.java:50）在com.sunopsis.dwg.dbobj.SnpSessTaskSql.processTask（SnpSessTaskSql.java:2925）在com.sunopsis.dwg.dbobj.SnpSessTaskSql.treatTask（SnpSessTaskSql.java:2637）在com.sunopsis.dwg.dbobj.SnpSessStep.treatAttachedTasks（SnpSessStep.java:577）在com.sunopsis.dwg.dbobj.SnpSessStep.treatSessStep（SnpSessStep.java:468）在com.sunopsis.dwg.dbobj.SnpSession.treatSession（SnpSession.java:2093）在oracle.odi.runtime.agent.processor.impl.StartSessRequestProcessor $ 2.doAction（StartSessRequestProcessor.java:380）在oracle.odi.core.persistence.dwgobject.DwgObjectTemplate.execute（DwgObjectTemplate.java:216）在oracle.odi.runtime.agent.processor.impl.StartSessRequestProcessor.doProcessStartSessTask（StartSessRequestProcessor.java:312）在oracle.odi.runtime.agent.processor.impl.StartSessRequestProcessor.access $ 0（StartSessRequestProcessor.java:304）在oracle.odi.runtime.agent.processor.impl.StartSessRequestProcessor $ StartSessTask.doExecute（StartSessRequestProcessor.java:874）在oracle.odi.runtime.agent.processor.task.AgentTask.execute（AgentTask.java:133）在oracle.odi.runtime.agent.support.DefaultAgentTaskExecutor $ 2.run（DefaultAgentTaskExecutor.java:84）在java.lang.Thread.run（Thread.java:745）

在“加载数据”步骤中编码：

        try {

                Connection sourceConnection = DriverManager.getConnection(sourceUrl); 
                Statement stmt = sourceConnection.createStatement();        
                Connection destinationConnection = DriverManager.getConnection(destinationUrl);
                Statement destStmt = destinationConnection.createStatement();
                SQLServerBulkCopy bulkCopy = new SQLServerBulkCopy(destinationConnection);
                SourceData = stmt.executeQuery(selectQuery);

                DestinationData = destStmt.executeQuery(selectQuery);
                bulkCopy.setDestinationTableName(destinationTable);

                out.println("--destination table: " +destinationTable);
                out.println("--select query: " +selectQuery);
        }   catch(SQLException se)
        {
                out.println("--Exception Occured while running Flex SQL. :"+se);
        } 
%>

我猜想SQLServerBulkCopy试图将一些内容写到out.println中，然后ODI要执行它。

我也不确定我做得正确。是否存在另一种方法？

使用SQLServerBulkCopy
