问题 I've done data imports with SQL Server's BULK INSERT task hundreds of times, but this time I'm receiving an error that's unfamiliar and that I've tried troubleshooting to no avail with Google. The below is the code I use with a comma deliminated file where the new rows are indicated by new line characters: BULK INSERT MyTable FROM 'C:\myflatfile.txt' WITH ( FIELDTERMINATOR = ',' ,ROWTERMINATOR = '/n') GO It consistently works, yet now on a simple file with a date and rate, it's failing with

问题 I'm going through this article on the sqlalchemy bulk insert performance. I tried various approaches specified in the benchmark test - SQLAlchemy ORM bulk_insert_mappings() , SQLAlchemy Core . Unfortunately for inserting 1000 rows all these methods required about 1min to insert them. This is horrendously slow. I tried also the approach specified here - this requires me building a large SQL statement like: INSERT INTO mytable (col1, col2, col3) VALUES (1,2,3), (4,5,6) ..... --- up to 1000 of

问题 I need to update or delete several documents. When I update I do this: I first search for the documents, setting a greater limit for the returned results (let’s say, size: 10000). For each of the returned documents, I modify certain values. I resent to elasticsearch the whole modified list (bulk index). This operation takes place until point 1 no longer returns results. When I delete I do this: I first search for the documents, setting a greater limit for the returned results (let’s say, size

问题 I use BULK INSERT for my text files. Everything works fine but one thing that I discovered, If I give the final line's final column a value, it will import. If the value of that final column in the final line is blank, it discards the line, despite the fact that the destination column allows nulls! Text file uses tab delimiter, here is example of the last row data: Mike Johnson 1/29/1987 M if I have any value in the last column field row will be inserted, example here: Mike Johnson 1/29/1987

问题 I have a table with the following data in one column: abc,2,2,34,5,3,2,34,32,2,3,2,2 def,2,2,34,5,3,2,34,32,2,3,2,2 I want to take this data and insert it into another table, using the commas as delimiters, just like how you can specify the FIELDTERMINATOR in BULK INSERT statements. Is there a way to do this using T-SQL? 回答1: You need to use a Split function to split your string into a table variable, and then insert those values into your table. There are tons of those split functions out

问题 I have an Excel file that originally had about 200 rows, and I was able to convert the excel file to a data table and everything got inserted into the documentdb correctly. The Excel file now has 5000 rows and it is not inserting after 30-40 records insertion and rest of all the rows are not inserted into the documentdb I found some exception as below. Microsoft.Azure.Documents.DocumentClientException: Exception: Microsoft.Azure.Documents.RequestRateTooLargeException, message: {"Errors":[

问题 Is there a limit to the number of documents one can bulk insert with PyMongo? And I don't mean the 16mb limit of document size for MongoDB, but the actual size of the list of documents I wish to insert in bulk through Python. 回答1: There is no limit on the number of documents for bulk insert via pymongo. According to the docs, you can provide an iterable to the collection.insert , and it will insert each document in the iterable, sending only a single command to the server Key point here is

问题 I have a CSV dump from another DB that looks like this (id, name, notes): 1001,John Smith,15 Main Street 1002,Jane Smith,"2010 Rockliffe Dr. Pleasantville, IL USA" 1003,Bill Karr,2820 West Ave. The last field may contain carriage returns and commas, in which case it is surrounded by double quotes. And I need to preserve those returns and commas. I use this code to import CSV into my table: BULK INSERT CSVTest FROM 'c:\csvfile.csv' WITH ( FIELDTERMINATOR = ',', ROWTERMINATOR = '\n' ) SQL
