sql server 2005 - Returning first line from a string -

I have a string in which there are three lines, how can I withdraw the first line from a string in i sqlserver.

Foreign currency:

  Declare as Narrator @ (200) set @ straw = 'this is for testing' + (four) + 'second line '+ Four (10) +' third line 'in some test tables    How can I return the first line from this?   
 
   SELECT SUBSTRING (@ Str, 0, CHARINDEX (char (10), @ str) ) Edit: If you have only text with one line, then you can use a case:    select CHARINDEX (Char (10), @ str) = 0 THEN @Str ELSE SUBSTRING (@ Str, 0, CHARINDEX (four (10), @ str)) END

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!

    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
