Hello,I need to find students that have 4 consecutive absences. When astudent is absent 4 times in a row, they can be dropped from the class.My class attendance file contains each attendance by date and whetherthey were present or not. When the student has 4 consecutive value 1(absent) for a given session and a given class the are considered to bedropped.If I needed to know the total number of absences, I know I could groupand summarize, but this one has the consecutive twist.Table:CREATE TABLE "dbo"."clsatt"("FULL_CLASS_ID" CHAR(15) NOT NULL,"STUDENT_ID" CHAR(20) NULL,"SESSION_ID" CHAR(10) NULL,"MEETING" SMALLINT NOT NULL,"PRESENT" CHAR(2) NOT NULL);Present value of 1 is absent, value of 2 is present (3 means holiday)Classes typically meet 12 times.I would want something likeFULL_CLASS_ID, STUDENT_ID, SESSION_ID, 'Dropped'as the output.Notice in the example the first student was absent the last 4 meetingsThe second student 5 absensesand the third student was totally absentIn these three examples, they are flagged as dropped.TIARobInserts:---------------------------------------------------------------------------------insert into clsatt values ('BUS100','1675812194','200203',1,'2')insert into clsatt
