  Hi,

  I need help in building following logic:

  Existing dataset:

  A 1 0 0 0 0

  A 0 1 0 0 0

  A 0 0 1 0 1

  A 0 0 0 1 0

  A 0 0 0 0 1

  B 0 1 0 0 0

  B 1 0 0 0 0

  Needed dataset:

  Col1 Col2 Col3 Col4 Col5 Col6

  A 1 1 1 1 1

  looks like a simple grouping problem..is this homework?

  SELECT

  Col1,

  MAX(Col2),

  MAX(Col3),

  MAX(Col4),

  MAX(Col5),

  MAX(Col6)

  GROUP BY Col1
