问题 I have two tables, one is a table #1 contains user information, email, password, etc.. the other table #2 contains item information when I do a insert into table #2 , and then use the returning statement, to gather what was inserted (returning auto values as well as other information), I also need to return information from table #1 .

问题 See important new discoveries 1 and 2 at end of this explanation. I am running Postgres 9.1.3 and am having a weird left join issue. I have a table named consistent.master with over 2 million rows. It has a column named citation_id , and that column has no nulls. I can verify that with this: SELECT COUNT(*) FROM consistent.master WHERE citation_id IS NULL That returns 0 . Here's where it gets weird: if I LEFT JOIN this table to a temporary table, I get an error that I am trying to insert a

问题 I've tried to insert variables into multiple rows at once in Web SQL database but with all known to me methods I'm getting errors: ("INSERT INTO tab (a,b) VALUES (?,?),(?,?)",[v1,v2,v3,v4]) >> could not prepare statement (1 near ",": syntax error) ("INSERT INTO tab (a,b) VALUES (?,?,?,?)",[v1,v2,v3,v4]) >> could not prepare statement (1 4 values for 2 columns) ("INSERT INTO tab (a,b) VALUES (?,?)",[v1,v2,v3,v4]) >> number of '?' does not match arguments count Which one is correct for Web SQL

问题 In DB2 I can do a command that looks like this to retrieve information from the inserted row: SELECT * FROM NEW TABLE ( INSERT INTO phone_book VALUES ( 'Peter Doe','555-2323' ) ) AS t How do I do that in Postgres? There are way to retrieve a sequence, but I need to retrieve arbitrary columns. My desire to merge a select with the insert is for performance reasons. This way I only need to execute one statement to insert values and select values from the insert. The values that are inserted come

问题 I am trying to write a few thousand records to sqlite DB. However after writing a random number of records - 122 / 45 / 180, it throws following exception: java.sql.SQLException: unable to open database file The random number of records get populated on DB but this error stops further record writing.

问题 Using Dapper I would like to implement a method that takes an IEnumberable of objects of type User . Now, User looks as follows: public class User { public int UserId { get; internal set; } public DateTime DateCreated { get; internal set; } public DateTime DateChanged { get; internal set; } public string Username { get; set; } } The point here is that UserId , DateCreated and DateChanged shall never be set via object, hence the internal keyword. Instead the database will populate these values
