upsert

I'm using the MERGE statement to upsert rows in an sql server 2008 database. However, my sproc is a single-row operation, whereas in fact I'd prefer to batch these. Is this even possible and, if so, how do I do it? Can you use Table-Valued Parameters in your proc? Take a look here http://www.sommarskog.se/arrays-in-sql-2008.html#TVP_in_TSQL to get some ideas Then in the proc you can use MERGE against the TVP i have created a proc called 'upsert' which takes a source table name, target table name, fields to join on, and fields to update (fields are separated by commas) and then does the merge

Using the answer from this question: Need MySQL INSERT - SELECT query for tables with millions of records new_table * date * record_id (pk) * data_field INSERT INTO new_table (date,record_id,data_field) SELECT date, record_id, data_field FROM old_table ON DUPLICATE KEY UPDATE date=old_table.data, data_field=old_table.data_field; I need this to work with a group by and join.. so to edit: INSERT INTO new_table (date,record_id,data_field,value) SELECT date, record_id, data_field, SUM(other_table.value) as value FROM old_table JOIN other_table USING(record_id) GROUP BY record_id ON DUPLICATE KEY

I'm trying to upsert with postgres using values from a select. It looks like: INSERT INTO foo (a, b, c) SELECT a_, b_, c_ -- hairy sql ON CONFLICT (...condition...) DO UPDATE SET "c"=??? On conflict, I want to use one of the values from my select statement, but I can't find the right syntax to alias it. How can I do this with Postgres? Use the excluded keyword: INSERT INTO foo (a, b, c) SELECT a_, b_, c_ -- hairy sql ON CONFLICT (...condition...) DO UPDATE SET c = excluded.c; 来源： https://stackoverflow.com/questions/44466232/postgres-upsert-using-results-from-select

I have a MongoDB document that saves occurrences of some things in a dictionary: { "id" : 1, "occurrences" : { "1" : 1, "2" : 5, "17" : 1, "35" : 4 } } I now want to add or update some entries, for example add a "12:3" to the occurrences, or update the number of occurrences of "17" to 2, so let's say as an example I want to add {"12":3} and {"17":2} to this dictionary. It is driving me crazy because I simply can not get it to work. I could use arrays and all that, but I would really like to have it in this particular design. Any ideas on how to solve this? I tried so many different things with

I have a web application which receives about 50 hits per second, and on each hit I am upsert'ing around 10 records in a central SQL Server database. Roughly once every 3 seconds I am upserting 5000+ rows for a single inbound connection. Currently I have a stored procedure which takes XML as a parameter. I do an INSERT into my main table from my XML where a row field doesn't match, then update the whole table with values from my XML. The operation isn't slow by any means, but I really would like to know the best way to do this. I am running on SQL Server 2005 so I don't have the MERGE
