Too Many Fields

Hi, I have a class with 71 propertys and fields.

I'm getting this error : "TPerson has too many fields".

Why there is a field quantity limitation? How can I handle It?

Re: Too Many Fields

Please, look at comments in SynCommons

const
  /// maximum number of fields in a database Table
  // - is included in SynCommons so that all DB-related work will be able to
  // share the same low-level types and functions (e.g. TSQLFieldBits,
  // TJSONWriter, TSynTableStatement, TSynTable)
  // - default is 64, but can be set to any value (64, 128, 192 and 256 optimized)
  // - this constant is used internaly to optimize memory usage in the
  // generated asm code, and statically allocate some arrays for better speed
  MAX_SQLFIELDS = 64;

so just set this const to 128 and recompile.

2AB - maybe change to 128 in main trunc - I'm unfortunately have objects with large number of fields to.
