Abinitio Interview Question # 1 - Write Multiple Files in Abinitio

Image
 Question :  I get records of various region in huge volume ,  we want to write the records in region specific files.   How to achieve that? View the explanation in the below video: Answer: -WMF WMF: filename::get_filename(in)= begin let string("") l_filename=string_substring(in.data.region); filename::string_concat($AI_SERIAL,"/",l_filename.dat); end; out::reformat(in)= begin out::in.data; end; OUTPUT DML-: DML record string(int) filename; string(integer(4)) file_contents; end; RMF: filename::get_filename(in)= begin filename::string_concat($AI_SERIAL,"/",in.filename); end; out::reformat(read,filename,in)= begin out.file_contents::read; out.filename::filename; end; Please view my youtube channel  DataPundit

  Metaprogramming in Abinitio 1. How to create output DML dynamically based in INPUT DML 2. How to create intermediate transform( XFR) dynamically based on INPUT DML      Please See my you tube video for explanation : PART 1 PART 2 For Example, let us say, we have an Input DML as below-: cat input.dml record string(",") name; decimal(",") age; decimal(",") salary; string(",") aadharid; date("yyyy-mm-dd")(",") joiningdate; string(",") mobileno=NULL; string(",") dlno=NULL; string(",") passportnumber=NULL; end; (1.1) prepare a new DML based on input DML i.e. add fields, remove fields, modify type Graph based parameters: ===================================================================== input_dml=$DIR/input.dml  [interpretation = constant] input_dml_info =$[read_type(input_dml)]   [interpretation = pdl] /* Define functions in AB_DML_DEFS */ AB_DML_DEFS= $[ out:: dynamic_dml_gen(input_dml_info)= beg...

Next In Sequence in ABinitio | How next_in_sequence() works in MFS

Image
https://youtu.be/JdDDpjZcv-4 next_in_sequence() working in Abinitio: Definition -      within a single process(component) , this gives successive number.   next_in_sequence()>1 i.e. all records whose occurance is 2 and more in the file.      for example dataset below:    employeeName ram shyam ravi hanuman shekhar seeta geeta shayama vidushi vishakha If we process by condition next_in_sequence()>1 then the output will be [first record will be removed] shyam ravi hanuman shekhar seeta geeta shayama vidushi vishakha 2. next_in_sequence() with reformat  - rely -  FieldA 1a 2a 3a 4a 5a 6a 7a Example 1 (serial processing)--> Reformat   count=2      select:   next_in_sequence()<900      Transofom1:   out:reformat(in)=   begin   out.*::in.*;   out.Seq-No::next_in_sequence();   end;      Transform2:   out:reformat(in)=   begin   out.*:...
