问题 I'm about to have to rewrite some rather old code using SQL Server's BULK INSERT command because the schema has changed, and it occurred to me that maybe I should think about switching to a stored procedure with a TVP instead, but I'm wondering what effect it might have on performance. Some background information that might help explain why I'm asking this question: The data actually comes in via a web service. The web service writes a text file to a shared folder on the database server which

Ques1: Can we create a stored procedure which will accept an array of objects in mysql? Ques2: Is there a way to bulk insert this data into mysql with Node JS? 回答1: You can bulk insert the array of records ,but before that you might need to convert it into array of

问题 I am using Sql Profiler all the time to capture the SQL statements and rerun problematic ones. Very useful. However, some code uses the SqlBulkCopy API and I have no idea how to capture those. I see creation of temp tables, but nothing that populates them. Seems like SqlBulkCopy bypasses Sql Profiler or I do not capture the right events. 回答1: Capturing event info for bulk insert operations ( BCP.EXE , SqlBulkCopy , and I assume BULK INSERT , and OPENROWSET(BULK... ) is possible, but you won't

问题 I have the following python code that copies content of a table on postgres DB1 and INSERTS into a similar table on postgres DB2. I want to speed it up by using BULK INSERTS. How do I achieve this import psycopg2 import sys import os all_data = [] try: connec = psycopg2.connect("host = server1 dbname = DB1 ") connecc = psycopg2.connect("host = server2 dbname = DB2 ") connec.autocommit = True connecc.autocommit = True except: print("I am unable to connect to the database.") cur = connec.cursor

问题 I am writing a small application that does a lot of feed processing. I want to use LINQ EF for this as speed is not an issue, it is a single user app and, in the end, will only be used once a month. My questions revolves around the best way to do bulk inserts using LINQ EF. After parsing the incoming data stream I end up with a List of values. Since the end user may end up trying to import some duplicate data I would like to "clean" the data during insert rather than reading all the records,
