overwrite

I need to write a row to the database regardless of whether it already exists or not. Before using NHibernate this was done with a stored procedure. The procedure would attempt an update and if no rows were modified it would fallback to an insert. This worked well because the application doesn't care if the record exists. With NHibernate, the solutions I have found require loading the entity and modifying it, or deleting the entity so the new one can be inserted. The application does have to care if the record already exists. Is there a way around that? Does the Id Matter? Assigned Id The

Let's say I want to replace the version number in a bunch of files, many of which live in subdirectories. I will pipe the files through gulp-replace to run the regex-replace function; but I will ultimately want to overwrite all the original files . The task might look something like this: gulp.src([ './bower.json', './package.json', './docs/content/data.yml', /* ...and so on... */ ]) .pipe(replace(/* ...replacement... */)) .pipe(gulp.dest(/* I DONT KNOW */); So how can I end it so that each src file just overwrites itself, at its original location? Is there something I can pass to gulp.dest()

The following command copies and moves a file but I also need it to overwrite the file it's replacing. xcopy /s c:\mmyinbox\test.doc C:\myoutbox Add /Y to the command line Benoit You can use : copy /b/v/y See SS64 on COPY . christopher.wr.schill Add /y to the command line of xcopy : Example: xcopy /y c:\mmyinbox\test.doc C:\myoutbox you need to simply add /Y xcopy /s c:\mmyinbox\test.doc C:\myoutbox /Y and if you're using path with spaces, try this xcopy /s "c:\mmyinbox\test.doc" "C:\myoutbox" /Y If the copy command is run from within a batch job you do not need to use the /Y switch: it will

I have a directory, 'Dst Directory', which has files and folders in it and I have 'src Directory' which also has files and folders in it. What I want to do is move the contents of 'src Directory' to 'Dst Directory' and overwrite anyfiles that exist with the same name. So for example 'Src Directory\file.txt' needs to be moved to 'Dst Directory\' and overwrite the existing file.txt. The same applies for some folders, moving a folder and merging the contents with the same folder in 'dst directory' I'm currently using shutil.move to move the contents of src to dst but it won't do it if the files

I have two classes, Field and Background . They look a little bit like this: class Field( object ): def __init__( self, a, b ): self.a = a self.b = b self.field = self.buildField() def buildField( self ): field = [0,0,0] return field class Background( Field ): def __init__( self, a, b, c ): super(Background, self).__init__( a, b ) self.field = self.buildField( c ) def buildField( self, c ): field = [c] return field a, b, c = 0, 1, 2 background = Background( a, b, c ) This error is pointing to Field's buildField() : "TypeError: buildField() takes exactly 2 arguments (1 given)." I expected

I am writing a program in Java where the output is written to a .txt file. Each time I run the program the file is overwritten. I do not want to use the append switch and add data to the file. I would like to have it so a new file, with the same name, is created each time I run the program. For example, if overflow.txt is the file name, and I run the program three times, the files overflow(1).txt , overflow(2).txt , and overflow(3).txt should be made. How can this be achieved? Check if the file exists, if so rename it. Using File.exists and FileUtils.moveFile You would need to do this
