• between - Select records with the number of bytes in the binary value between the At least and At most values, inclusive.

If we would like to select records that are NOT variations of the above, for example not between, select on the basis of one of the above and press Ctrl-I or Edit - Select Inverse to invert the selection.   Selecting using between and then pressing Ctrl-I is the equivalent of "not between" the given values.

Unique

Selects records based on how many times their values occur in a table:

• duplicate - for each duplicate value, selects all such records except one,
• non-unique - selects records with values that occur more than once,
• unique - selects records with values that occur only once.
