SSIS Derived Column - Is there a good way to trim 400+ columns? -

-

i have import fixed width flat file , has 486 columns. each 1 needs trimmed before arriving database. know derived column allows me 1 @ time, there way mass rtrim(ltrim( on columns?

two ways (both biml ways assumed you've gathered metadata column names):

1 - script

two ways here also: inputbuffer, or biml row. function inputbuffer provided , i'm sure can create own row.

public class scriptmain : usercomponent {   private pipelinebuffer inputbuffer;   public override void preexecute()   {     base.preexecute();   }   public override void postexecute()   {     base.postexecute();   }    public override void processinput(int inputid, microsoft.sqlserver.dts.pipeline.pipelinebuffer buffer)   {     // need access pipelinebuffer isn't exposed in processinputrow     inputbuffer = buffer;     base.processinput(inputid, buffer);   }    public override void input0_processinputrow(input0buffer row)   {     stripleadingtrailingwhitespacebyinputbuffer(inputbuffer);      // biml     <#       foreach (var column in table.columns)       {         var colname = column.name.tostring().replace("_","");     #>     row.<#= colname #> = stripleadingtrailingwhitespacebystring(row.<#= colname #>);     <#         }       }     #>   }    public void stripleadingtrailingwhitespacebyinputbuffer(microsoft.sqlserver.dts.pipeline.pipelinebuffer inputbuffer)   {       (int = 0; < inputbuffer.columncount; ++i)       {           if (inputbuffer[i] != null)               inputbuffer[i] = inputbuffer[i].tostring().trim();       }   } }

2 - derived column biml

foreach (var column in table.columns) {     var colname = column.name;     #>                                   <derivedcolumns name="(dco) stripwhitespace">         <columns>           <column name="derive_<#= colname #>" datatype="ansistring" length="255">stripwhitespace(<#= colname #>)</column>         </columns>     </derivedcolumns>     <#   } #>

java - Static nested class instance -

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
