Question

我在数据流，SSIS包的控制流程中有以下SQL查询，我想通过切断点限制记录，并且切断点是系统的当前日期/日期。所以，它应该只显示过去的记录，不包括今天的记录。所以，我认为我需要使用特定字段（这是日期字段 - 在查询中称为'FinalCloseDate'并与当前系统日期进行比较，并告诉它仅提取之前发生的记录（可能是＆lt;今天的日期）今天或当前的系统日。

@Bean
@InboundChannelAdapter(value = "dailyFileInputChannel", poller = @Poller(maxMessagesPerPoll = "1", fixedDelay = "${load.manualPollingInterval}"))
public MessageSource<File> messageSource(ApplicationProperties applicationProperties) {
     FileReadingMessageSource source = new FileReadingMessageSource();
     source.setDirectory(applicationProperties.getLoadDirectory());
     CompositeFileListFilter<File> compositeFileListFilter = new CompositeFileListFilter<File>();
     compositeFileListFilter.addFilter(new LastModifiedFileListFilter());
     FileSystemPersistentAcceptOnceFileListFilter persistent = new FileSystemPersistentAcceptOnceFileListFilter(store(), "dailyfilesystem");
     persistent.setFlushOnUpdate(true);
     compositeFileListFilter.addFilter(persistent);
     compositeFileListFilter.addFilter(new SimplePatternFileListFilter(applicationProperties.getFileNamePattern()));
     source.setFilter(compositeFileListFilter);
     return source;
}

@Bean
public PropertiesPersistingMetadataStore store() {
    PropertiesPersistingMetadataStore store = new PropertiesPersistingMetadataStore();
    store.setBaseDirectory(applicationProperties.getProcessedStoreDirectory());
    store.setFileName(applicationProperties.getProcessedStoreFile());
    return store;
}

@Bean
@ServiceActivator(inputChannel = "dailyFileInputChannel")
public MessageHandler handler() {
    // return a handler that processes and moves the file
}

到你的AND dbo.Producthit.FinalCloseDate < CAST(GETDATE() AS DATE)条款。
