| I need help to create the right SQL statment for my issue.In the table are two different values separated by counter. FIELDNR- the Cardnr (021)- the percent to Cardnr (022)- PSNR is Personalnr from each Employee- PFLFDNR is a seq. number for the fields 21 and 22 it show how many rows each Fieldnr already hasThe values are identified with the help of the date field PFGLTFROM and PFGLTTO. You must select of both records from a Personalnr always one active date out. Example: FIRMA PSNR FIELDNR PFLFDNR VALUE PFGLTFROM PFGLTTORows for Persnr=64 and Cardnr=21 in different times (but we need only one record which is valid from and to date1 64 021 1 2901009749 20110101 201405311 64 021 2 24 20140601 20321231Rows for Persnr=64 and Cardnr=22 Percent in different times (but we need only one record which is valid from and to date1 64 022 1 1 20110101 201207311 64 022 2 0 20120801 201209071 64 022 3 0.77 20120908 20120930............................1 64 022 9 0 20140714 201408151 64 022 10 1 20140816 20320101Parameter: From and To DateThis should be the OutputThxzero1deI select the 2.row from Field=021 because it has the actual date PFGLTFROM=2014.06.01 PFGLTTO=2032.12.31and the value from Fieldnr=22 is 1 because it has the actual date PFGLTFROM=20140816 PFGLTTO=20320101FIRMA PSNR FELDNR PFLFDNR Value1 Value2 PFGLTFROM PFGLTTO1 64 021 2 24 1 20140601 20321231I hope I could explain my problem :) |
