Hai sir
I had a table that contain fields
EMPCODE NUMBER
EMPNAME VARCHAR2(25)
BARCODE VARCHAR2(25)
INTIME VARCHAR2(25)
OUTTIME VARCHAR2(25)
INTRTIMEIN VARCHAR2(25)
INTROUTTIME VARCHAR2(25)
PERTIMEIN VARCHAR2(25);
PERTIMEOUT VARCHAR2(25);
ATTEND_DATE DATE ;
Consider that a table with 6 fields ie timein,intrtimein,pertimein,pertimeout,intrtimeout,timeout
I have generating a attendance table and a table contain 6 various times for an employees and we need to arrange it in order
0815,0816,1230,1250,1645,1646
If 0815 is the starting time then timein ie mintime
0816 stored to be in intrtime
then1250 then it stored in pertimein
then 1230 then it stored in pertimeout
then 1645 stored in intrtimeout
then 1646 stored in timeout
I tried with max and min function but its not working properly pls tell me some solutions
Thanks & Regards
