表内容统计解决办法

表内容统计
有表A,字段为文本型
字段1   字段2   字段3   字段4
  A           B           C             D
  B           B           C             C  
  C           C           C             C
  E           F           G             H  

要求得出:
字段1   字段2   字段3   字段4       统计
  A           B           C             D           1A1B1C1D  
  B           B           C             C           2B2C
  C           C           C             C           4C
  E           F           G             H           1E1F1G1H
做何做?谢谢!

repl 统计 with f
