请帮我将数据从sql临时表传输到文件 [英] Please help me transfer the data from sql temporary table to a file

问题描述

我在这里粘贴存储过程代码。此存储过程由应用程序（在C＃中）进行处理，以在.CSV中生成报告。存储过程适用于小数据，但如果数据很大（99％的时间），则sp无法发送整个数据，因此我必须以块的形式分解数据并将其提供给.CSV。我尝试了很多东西，比如将数据分成块，然后尝试将其发送到.CSV，但它没有帮助。只有第一批数据才能在.CSV中找到。请帮助我，以便我可以发送数据而不是批量数据。





注意：请专注于评论在下面的SP中：这个选择查询将整个数据发送到报告，我想我们必须在这里更改代码 - 上半部分的代码生成报告并对其进行格式化。



从slno记录订单中选择记录







请在最早的时候帮助我



存储过程：

Hi,

I am pasting a stored procedure code here. this stored procedure is caleed by an application( in C#) to generates a report in .CSV. The stored procedure works fine for small data but if the data is huge ( 99% of the times ) , the sp is not able to send the entire data, hence I have to break the data in chunks and give it to the .CSV. i tried many thing , like dividing the data in chunks and then try sending it to the .CSV, but it did not help. ONLY THE FIRST CHUNK OF DATA WAS FOUND IN THE .CSV. Please help me so that i can send the data in chunks rather than bulk.


NOTE : Please concentrate on the comment in the below SP: This select query sends the entire data to the report, i guess we have to change the code here-- The code in the upper half generates the report and format it.

select record from records order by slno



PLEASE HELP ME AT THE EARLIEST
