Hello, I got the following problem, that I cannot get worked out. I have a table that has 3 columns A, B and C. C is a boolean Column, that indicates if the record has been logically deleted, It shall not be removed from the database. The table shall be ordered according to A. (Order by A) But if C ist true and to the value B1 in this Record, there exists another Record with B2 and B2 = B1, then B1 should be ordered in the row above B2. B A C 1=true, 0 = false 307 {null} 1 307 {null} 1 307 {null} 1 307 1.7 0 301 1,5 1 301 2 0 304 3 0 305 3 1 305 3 0 Thank you very much for any help.
