Logging Table Columns Guidelines

image\Guide.gif Guidelines for logging table columns include:

A table can have, at most, 250 columns. The number of columns you can actually have in a group table depends on the type of data you are storing.

A record being added to the database can have at most 2 KB of data.

With overhead, 2 KB amounts to approximately 222 8-byte floating-point numbers. (Points with Engineering Units conversion are stored in floating point format.)

If you are storing a number of floating-point numbers or long text strings in a group record, it is recommended that you verify that the 2-KB limit is not being exceeded.
