This ‘Follow Up’ table has a number type column called, and I would like this column to record a sequentially incrementing number (like 1, 2, 3 etc.) when a new “Follow up” record of a patient is made, but that also means if a “Follow up” record is made on another patient, that patient’s should start afresh with 1, and then go up as 2, 3 etc. The Serial Number (s/n) is a ten-digit - 4671356. So the ‘Follow Up’ table is a “child” table referenced to the ‘Patient Bank’, which means the ‘Follow Up’ table has a column with a UNIQUEID() expression for each entry, and a column that fetches the relevant from the ‘Patient Bank’ table pertaining to the patient. type FA - 10266 / 10, unit 11, decoder unit, serial nos. The next table called ‘Follow Up’ records follow up details of each patient. Can I ask you for a modification of this that would help me to assign sequential numbers to a set of rows in a table? What I mean by that is, let’s say I have 2 tables on my app, the first is ‘Patient Bank’ that records basic patient details like the name, age, gender etc. Then, each time a serial number is assigned, it will be the lowest unused number in the sequence. Replace the Initial value expression of the original Serial column with: MIN(

To fill-in sequence gaps and reuse deleted serial numbers for new rows:Ĭreate an additional virtual column named (e.g.) Next Serial of type Number and with the App formula expression: ( + 1) If a row with a serial number is deleted, a gap in the numeric sequence will occur. Each new row will get a serial number one greater than the highest serial number already in use. One way to implement serial numbers is with a normal (not virtual) column named (e.g.) Serial of type Number and an Initial value expression of (MAX(MyTable) + 1). For this reason, serial numbers are strongly discouraged! Basic Serial Numbers In general, sequential numeric identifiers (i.e., serial numbers) are risky in AppSheet: if two users happen to add rows at the same time, both rows could be assigned the same serial number, which could lead to confusion (at the least) or data loss (at the worst).
