    We plan to use datatables in our customizations. We did, however, not find documentation specifying how long a datatable column for string values can be - 4000 characters, 65536 characters,...

    How big is this size limit for a string column in a datatable?

    Regards, Wolfgang

    If the column is a key it's limited to 256 characters, otherwise I am not sure there is an explicit limit on the size, I have had test data over 100,000 characters, the field is basically a blob, but it's not intended to hold novels since these are meant to be internal lookups.

    The limit for non-key strings is 262144 characters (ie, 256 * 1024). For the key string value, the max is 256
