Bulk insert with text qualifier in SQL Server

生来就可爱ヽ(ⅴ<●) 提交于 2019-11-27 05:33:12
I am trying to bulk insert few records in a table test from a CSV file , CREATE TABLE Level2_import (wkt varchar(max), area VARCHAR(40), ) BULK INSERT level2_import FROM 'D:\test.csv' WITH ( FIRSTROW = 2, FIELDTERMINATOR = ',', ROWTERMINATOR = '\n' ) The bulk insert code should rid of the first row and insert the data into the table . it gets rid of first row alright but gets confused in the delimiter section . The first column is wkt and the column value is double quoted and has comma within the value . So I guess I question is if there is a way to tell the BULK INSERT that the double quoted

Does a MySQL multi-row insert grab sequential autoincrement IDs?

会有一股神秘感。 提交于 2019-11-27 04:39:20
问题 I think this is true, but I haven't found anything on the web to confirm it. I can get the first id generated for the autoincrement field using last_insert_id(), but can I assume that the next records will have sequential IDs? Or could another user grab an id so that the resulting IDs are not sequential? Example: insert into mytable (asdf, qwer) values (1,2), (3,4), (5,6), ... , (10000,10001); If mytable has an autoincrement column, and if two users run this statement at the same time, will

Ignore certain columns when using BULK INSERT

问题 I have a comma delimited text file with the structure field1 field2 field3 field4 1 2 3 4 I wrote the following script to bulk insert the text file, but I wanted to leave out column 3 create table test (field1 varchar(50),field2 varchar(50),field4 varchar(50)) go bulk insert test from 'c:\myFilePath' with (fieldterminator=',', rowterminator='\n' ) The insert worked fine, but the results of the insert made field4 look like field3,field4, so the field 3 was actually just concatenated onto

Bulk insert in Java using prepared statements batch update

允我心安 提交于 2019-11-27 03:57:57
问题 I am trying to fill a resultSet in Java with about 50,000 rows of 10 columns and then inserting them into another table using the batchExecute method of PreparedStatement . To make the process faster I did some research and found that while reading data into resultSet the fetchSize plays an important role. Having a very low fetchSize can result into too many trips to the server and a very high fetchSize can block the network resources, so I experimented a little bit and set up an optimum size

Bulk Insert records into Active Record table

末鹿安然 提交于 2019-11-27 01:28:48
I found that my Model.create! statements were taking a very long time to run when I added a large number of records at once. Looked at ActiveRecord-Import but it didn't work with an array of hashes (which is what I have and which I think is pretty common). How can I improve the performance? Use the activerecord-import gem. Let us say you are reading a CSV file and generating a Product catalogue and you want to insert records in batches of 1000: batch,batch_size = [], 1_000 CSV.foreach("/data/new_products.csv", :headers => true) do |row| batch << Product.new(row) if batch.size >= batch_size

Android: Bulk Insert, when InsertHelper is deprecated

无人久伴 提交于 2019-11-27 00:23:32
问题 There is plenty answers and tutorials using InsertHelper to do fast bulk insert in SQLiteDatabase. But InsertHelper is deprecated as of API 17. What is now the fastest method to bulk insert large sets of data in Android SQLite ? So far my greatest concern is that SQLiteStatement is not very comfortable to work with, where InsertHelper had binding columns and binding values, which was kind of trivial. 回答1: SQLiteStatement has also binding methods, it extends SQLiteProgram. Just run it in

How can I get a trigger to fire on each inserted row during an INSERT INTO Table (etc) SELECT * FROM Table2?

问题 I've been trying to avoid using a cursor in this particular case just because I dislike the tradeoffs, and it just so happens a process I'm using makes triggers look like the proper course of action anyway. A stored procedure inserts a record based off of a complicated mix of clauses, using an insert trigger I send an email to the target user telling them to visit a site. This is easy and works fine. However, another procedure is to run nightly and redistribute all unviewed records. The way I
