剛學SAS不久,健保資料庫用SAS跑 我想把兩個檔案串檔 (CDOO和承保檔串連，我用ID當作串連的變數) 但試了很多次，都出現錯誤 ERROR: BY variables are not properly sorted on data set R.R301_ID2003_1. ID=6ee4eaf451d609607087ec76a86d4bec INS_ID_TYPE=2 ID_BIRTHDAY=19880627 ID_SEX=F UNIT_INS_TYPE=52 AREA_NO_I=0101 a1= HOSP_ID= age=. male=. DRUG_NO= FIRST.ID=0 LAST.ID=1 _ERROR_=1 _N_=4 NOTE: The SAS System stopped processing this step because of errors. NOTE: There were 2 observations read from the data set R.R301_ID2003_1. NOTE: There were 4 observations read from the data set R.R301_CDOO2003. WARNING: The data set R.R301_CDOOID2003 may be incomplete. When this step was stopped there were 3 observations and 11 variables. WARNING: Data set R.R301_CDOOID2003 was not replaced because this step was stopped. 想請問該怎麼做? 我真的不知道錯在哪= =... 謝謝 --
