I am creating a data entry form in Maintain. I have one key field "STUDENT_ID"in SQL database. So it is taking only unique value. For example, if I enter this STUDENT_ID "1111" in my form , it allow me to enter first time . But I want to enter the same field STUDENT_ID value “1111" Many times. I want to make this field "STUDENT_ID" as second key. Is it possible, Can I define a new field in the master file and make it as Primary key field? I appreciate any suggestion regarding this issue.

My Master file Below:
FILENAME=ASSISTLEARNLAB, SUFFIX=SQLMSS , $
SEGMENT=ASSISTLEARNLAB, SEGTYPE=S0, $
FIELDNAME=STUDENT_ID, ALIAS='Student ID', USAGE=A7V, ACTUAL=A7V,

Maintain requires that your key fields are first n fields in your Master. So, you COULD enter a second field and make that and STUDENT_ID the key fields, but you will have to recreate the database. Here I am adding STUDENT_CNT (count) as the second key in the Master. You also have to change the KEYS in the Access file to 2.

FILENAME=ASSISTLEARNLAB, SUFFIX=SQLMSS , $
SEGMENT=ASSISTLEARNLAB, SEGTYPE=S0, $
FIELDNAME=STUDENT_ID, ALIAS='Student ID', USAGE=A7V, ACTUAL=A7V,
TITLE='Student ID', $
FIELDNAME=STUDENT_CNT, ALIAS='Student Count', USAGE=I3, ACTUAL=I3,
TITLE='Student Count', $
FIELDNAME=LAST_NAME, ALIAS='Last Name', USAGE=A50, ACTUAL=A50,
MISSING=ON,
TITLE='Last Name', $
FIELDNAME=FIRST_NAME, ALIAS='First Name', USAGE=A50, ACTUAL=A50,
MISSING=ON,
TITLE='First Name', $
FIELDNAME=DATE, ALIAS=Date, USAGE=YYMD, ACTUAL=DATE,
MISSING=ON, $
FIELDNAME=COURSE, ALIAS=Course, USAGE=A10, ACTUAL=A10,

FIELDNAME=DETAILED_REASON_FOR_VISIT, ALIAS='Detailed Reason for visit', USAGE=A50, ACTUAL=A50,

FIELDNAME=TUTOR, ALIAS=Tutor, USAGE=A50, ACTUAL=A50,

Now you can have multiple student IDs and just increment STUDENT_CNT each time.

Mark is right, make sure the first n fields are your keys, and set the Keys in the ACX to match.

I would suggest using a date time field for the other Key, as you will not have to keep track of any counter to increment.

Thank you both of you, Now I able to add values many times to The Student_ID" Field.
