![]() This is a re-submission of a post that got caught in the spam filter. Hopefully it'll get through this time because i'm interested in what exactly is happening. When I launch GVim from the command line it successfully finds my vimrc file in my home folder by using the HOME environment variable. When I launch GVim from the start menu it uses the HOMEDRIVE and HOMEPATH environment variables which are set to incorrect legacy values and so it doesn't find my vimrc file and displays error messages on launch. The simple solution is for me to reset the HOMEDRIVE and HOMEPATH values, but i'm most interested in why vim is displaying different behaviour depending on where it's launched from. I can type gvim at the command prompt and have the program open perfectly normally. However, I receive this error message if I launch GVim by double clicking a file-type which has been associated with it, or if I launch it from the start menu. When I exit GVim in this state then I get this error message: E138: Can't write viminfo file P:\_viminfo! When I click through the message then GVim opens in its most basic form, without reading my vimrc file. I don't have a P drive letter mapped so this may or may not be revealing. Sure enough, vimrc_example.vim does not exist in the folder specified in the error message. What is the purpose of this vimrc_example file? i can see it's read on line 2 of c:\Program Files (x86)\Vim_vimrc: source $VIMRUNTIME/vimrc_example.vim I'm fairly sure that in the past i've been able to open GVim via any method and not receive this message. $VIMRUNTIME seems to be the same whether I launch from the command prompt or through other means. The good news is we can hide it.I also checked my environment variables and the command line GVim is launching the same executable as when I launch from the start menu.Ä®dit: the plot thickens. The bad news is that we canât drop the column. For our purpose, the ârow endâ column in the base table will by definition always contain the timestamp 23:59:59.9999999, so we donât really need or want the column hanging around. If you set the Time Zone in raspi-config the Raspberry Pi will automatically update the time on boot, if connected to the internet. When you create a temporal table, you need to specify both a ârow startâ and ârow endâ column, and those columns will live in both the base table and the history table (if any). ![]() SQL Server does not allow you to update these special columns because theyâre used for system versioning (which we donât technically use here, but still). This may be a problem or a feature depending on your use case. Keep this in mind, as you may encounter rows where the âcreatedâ timestamp (which is a regular column default) is slightly later than the âupdatedâ, because of this phenomena. Here's what I wan to do: cnoreabbrev newfile cd some/directory/ e filename currentdate So basically creating a new file with the current time attached to the name of the file.This is true for both implicit and explicit transactions â especially if the INSERT or UPDATE is a long-running statement, the âUpdatedâ column will reflect the start time of that transaction or long-running statement, not the time the statement ran or completed. The timestamp you see in the âUpdatedâ column will be the start of your transaction. This is a weird one if you havenât seen it before. For our purposes, itâs something to keep in mind if youâre used to working with local time. This obviously makes a lot of sense when you use history tables, since you donât want them to break when your server goes from daylight savings time back to normal time. However, the generated values are in UTC time, not in the serverâs local time zone. ![]() Quirks and features of temporal tables UTC time, not localįor temporal tables, the row start and row end columns must be defined as datetime2 (though you can set any precision you like). As long as we donât add the WITH (SYSTEM_VERSIONING=ON) clause, we just get to use the GENERATED ALWAYS columns to keep track of the update timestamp. Temporal tables are not system versioned until you actually add a history table. âHold you horsesâ, I hear you say, âI donât need to version the data, I just want the timestamps.â PERIOD FOR SYSTEM_TIME (Updated, ValidUntil) ValidUntil datetime2(7) GENERATED ALWAYS AS ROW END NOT NULL,ĬONSTRAINT PK_dbo_SomeTable PRIMARY KEY CLUSTERED (a, b), Updated datetime2(7) GENERATED ALWAYS AS ROW START NOT NULL, Created datetime2(7) DEFAULT (SYSUTCDATETIME()) NOT NULL,
