Segmenting the data in the table

Hello,

I need to create the segmentation on a table. Below is the original data in the table.

Begmeasure       EndMeasure       DetMethod         Testpressure

0                          7703                   Acceptable          1006

7703                     32149                Acceptable           1007

8323                     32149                Not Verified           1010

8323                     32149                Not Verified           1010

10988                   32149                Acceptable             1010

Forst row should be compared to its next row. If the next row beg and end measures are in between the first row's beg and end measures or overlaps with the first row, and first row method is " acceptable" and the test pressure is smaller, the first row segment stays as the final record. The logic has to loop through every subsequent row untill there is no overlap between the two compared rows.

As shown below, the rows 3 and 4 are elimated/replaced with 2nd row becuase the detmethod is "Not Verified". Only 2 types of methods exists in the table, "Acceptable" and "Not Verified". In this 10988 is less than 32149, So its an overlap. So, we have to segment as 7703 to 10988 and 10988 to 32149. I want the result set to be like this below:

After Segmentation :

BegMeasure                EndMeasure           DetMethod             Testpressure

0                                     7703                     Acceptable               1006

7703                               10988                   Acceptable                1007

10988                             32149                   Acceptable                 1010

Please help me in achieving this. Thanks so much for all the help.

Thank You
