テキストファイルをmysqlテーブルにインポートする

Question

MySQLを使用してSQLテーブルにデータをインポートしようとしています。しかし、テキストファイルのデータは別の方法で配置されます。そのような例が1つあります。

#n O. Willum 
#a Res. Center for Microperipherik, Technische Univ. Berlin, Germany 
#pc 1 
#cn 0 
#hi 0 
#pi 0.0000 
#upi 0.0000 
#t new product;product group;active product;long product lifetime;old product;product generation;new technology;environmental benefit;environmental choice;environmental consequence 

#index 2 
#n D. Wei 
#a Dept. of Electr. & Comput. Eng., Drexel Univ., Philadelphia, PA, USA 
#pc 1 
#cn 0 
#hi 0 
#pi 0.0000 
#upi 0.0000 
#t lowpass filter;multidimensional product filter;orthonormal filterbanks;product filter;new approach;novel approach;challenging problem;iterative quadratic programming;negligible reconstruction error;spectral factorization 

このテキストファイルをSQLファイルに変換するにはどうすればよいですか？

Answer 1

少しAWKスクリプトでテストできます。 tablename 2xを変更し、フィールド名を実際のものに置き換えてください。出力をファイルにリダイレクトし、mysqlクライアントで直接実行することができます。

awkスクリプト

bash-3.2$ cat gen.awk 
BEGIN { 
     FS=" " 
     print "-- createt by gen.awk" 
     print "-- written by Bernd Buffen" 
     print "-- buffen@t-online.de" 
     print 
     out="INSERT INTO myTable SET " 
     ok=0; 
} 
{ 
     if($1 != "") { rem="-- " 
     for(i=1;i<=NF;i++) 
     { 
      rem=rem" "$i 
     } 
     } 
     print rem; 



     if($1 == "#n" ) {out=out""sep"fieldname_n='"; ok=1;sep=", "; } 
     if($1 == "#a" ) {out=out""sep"fieldname_a='"; ok=1;sep=", "; } 
     if($1 == "#pc") {out=out""sep"fieldname_pc='"; ok=1;sep=", "; } 
     if($1 == "#cn") {out=out""sep"fieldname_cn='"; ok=1;sep=", "; } 
     if($1 == "#hi") {out=out""sep"fieldname_hi='"; ok=1;sep=", "; } 
     if($1 == "#pi") {out=out""sep"fieldname_pi='"; ok=1;sep=", "; } 
     if($1 == "#upi") {out=out""sep"fieldname_upi='"; ok=1;sep=", "; } 
     if($1 == "#t" ) {out=out""sep"fieldname_t='"; ok=1;sep=", "; } 
     if(ok == 1) 
     { 
      tmp=$2 
      for(i=3;i<=NF;i++) 
      { 
       tmp=tmp" "$i 
      }; 
      out=out""tmp"' "; 
      ok=0; 
     } 

     if($1 == "") 
     { 
      print out";" 
      print; 
      out=""; 
      sep=""; 
      out="INSERT INTO myTable SET "; 
      ok=0; 
     } 
}
