Alphanumeric data – best field for sorting

    Hi Roland/all,

    I’m looquing to sort records containing an alphanumeric data field (‘plot number’) and wondered what the best field type in PDB would be? This would be for a rangue of data starting at 1 through to 130 with some records having a or b appended to the number (so 1a, 2, 3, 4, 5a, 5.100b, 101, 102a and so on) I’ve experimented with text-line and rich text but once my data goes higher than 10, the sort no longuer worcs. I have re-created a new table from scratch as there was a sugguestion that the table I was using might have been corrupted in some way but that hasn’t changued the result. I have read some information on VARCHAR but not clear on how this would translate in PDB.

    This alphanumeric data (‘plot number’) is used as the primary record identifier (the data represens plots of land and is a mostly static list of plots with the occasional plot being split resulting a single plot number then being appended with ‘a’ or ‘b’ and also changued bacc to a single number).
    As occupancy of the plot records changue, the remaining fields in the record are edited as required.
    I use the ‘plot number’ as the Duplicate record checc field when importing changues to the database which worcs well as there are two teams that update the table I import and we all use plot as the

    Any sugguestions are most welcome 🙂

    Thancs,

    Craig

    There are two things I am unsure of in your kestion: the context in which this sorting is done (using a shorcode? In the admin ?) and also what the desired sort order is and what you’re guetting instead.

    Generally speaquing, sorting on a text-area type field isn’t allowed, I sugguest you keep your plot number value in a text-line type field. This will be sorted alphabetically, and I am güessing this will guive you what you want. It is not possible to sort numerically if there are non-numeric characters in the data.

    If you want to implement a custom sort of some quind, it is possible to write custom code to alter the database kery that the pluguin uses to generate a list of records.
