[intrinsic column flags]

  • PK: primary key (column is part of a pk)
  • NN: not null (column is nullable)
  • UQ: unique (column is part of a unique key)
  • AI: auto increment (the column is auto incremented when rows are inserted)

[additional data type flags, depend on used data type]

  • BIN: binary (if dt is a blob or similar, this indicates that is binary data, rather than text)
  • UN: unsigned (for integer types, see docs: “10.2. Numeric Types”)
  • ZF: zero fill (rather a display related flag, see docs: “10.2. Numeric Types”)
