Good day everyone,I have few tables where i need to delete above 50 million rows each. Since i dont want to delete them all in one shot and block my table for extended time, i am trying to use limit with delete but its giving me error every time. May i please get some assistance here? ThanksHere is what i am running:delete from mytable where id in (select id from mytable where condition=true limit 1000);where i run this, i get following error:Error: current transaction is aborted, commands ignored until end of transaction block.SQL state: 25P02.I am running it in RDS.TIA, Best,Rohit
As others said, there is no limit with the UPDATE/DELETE statements in PostgreSQL. However, you can get around that using a common table expression (CTE). We have a blog post on doing exactly this up at CrunchyData
