问题 Check out this list. I need each one turned into a variable and set equal to 0. Example: ;1-Methyoxy-2-Propanol would be: $OneMethoxyTwoPropanol = 0 ;and 1,2-BUTADIENE would be: $OneTwoButadiene = 0 Assigning them to a variable wouldn't be a problem, but there are 1500 of them. 回答1: If i had to do this work i'll make it this way : I'll change the case of each word : Regex to change to sentence case Make a "SearchAndReplace" : 1 -> One 2 -> Two ... {underscore} -> '' {space} -> '' ... Then in

问题 What would be the fastest way of retrieving data from the Oracle DB via OLEDB? It should be portable (have to work on Postgres and MS SQL), only one column is transfered (ID from some large table). Current performance is 100k rows/sec. Am I expecting too much if I want it to go faster? Clarification: datatable has 23M records Query is: SELECT ID FROM OBJECTS Bottleneck is transfer from oracle to the client software, which is c++/OLEDB 回答1: What the heck, I'll take a chance. Edit: As far as

问题 I have a CSV file in the following format key1,key2,key3,counter1,counter2,counter3,counter4 1,2,1,0,0,0,1 1,2,2,0,1,0,4 The CQL3 table has all value columns of type 'counter'. When I try to use the COPY command to load the CSV I get the usual error which asks for an UPDATE instead of an INSERT. The question is : how can I tell CQL to use an UPDATE ? Is there any other way to do this ? 回答1: using sstables solved this issue. Although a little slower than what i expected , it does the job 回答2:

问题 Not sure if I'm missing anything here. Basically, I am looking for Linq to Nhibernate to do the following SQL statement: update SomeTable set SomeInteger = (SomeInteger + 1) where SomeInteger > @NotSoMagicNumber Is there any way to do that? Thanks! 回答1: Linq (not Linq to NHibernate, Linq in general) does not have a bulk update verb like SQL has. If you need the efficiency of the bulk update statement like yours, I'd just stick to SQL. 回答2: Late answer but it now exists in Nhibernate 5.0. // /

问题 I have written a method for sending emails in bulk but it is very very slow (around 3 mails every 10 seconds). I want to send thousands of mails. Is there any way to do this much more faster? I am using gmail now but only for test, finally I want to send using my own SMTP server. Here is the code: public boolean sendMessages() { try { Session session = Session.getInstance(this._properties, new javax.mail.Authenticator() { @Override protected PasswordAuthentication getPasswordAuthentication()

问题 we're using ZyWall to guard our servers from external intrusions. It generates daily log files with huge sizes, over a GB, sometimes 2 GBs. They ususally contain more than 10 millions of lines. Now my task is to write an application that will import these lines into Oracle database. I'm writing it in C#. What I'm currently doing is: I read the logfiles line by line. I do not load the whole file at once: using(StreamReader reader=new StreamReader("C:\ZyWall.log")) { while ((line=reader

问题 The environment for the given objective is not currenly available, hence, I'm not able to try out things and have to rely on the analysis only ! My objective can be broken into the following distinct steps : Uploading huge files(upto 100GB ) using a dumb 'Upload File' page - there is no escape from this as the users want a (dumb)front-end and are not willing to ftp the file etc. The web application which provides the above front end will be hosted on a low-end machine - 2GB RAM and 40GB HDD

问题 I am looking for a way to pull XML from a SQL database and shred the XML via SSIS in bulk. I currently have a package that can pull XML from the database and pass the XML to a stored procedure, via variable, for shredding but this only works 1 record at a time. When processing 100,000 records, this can become quite time consuming. I would like to shred multiple XML values at once using SSIS. Is this possible with SSIS? Perhaps something in a Data Flow Task where all the XML values are
