I have a table called Counties which partially contains a lot bad
data.&nbsp; By" bad data", I mean some records are missing; some exist and
shouldn't; and some records have fields with erroneous information.&nbsp;
However, the majority of the data in the table is accurate.&nbsp; I have
built/loaded a new table called newCounties with the same structure as
Counties, but contains no bad data.&nbsp; My was&nbsp; to completely replace the
contents of Counties with the contents of newCounties.&nbsp; The problem is:
several other tables have Foreign Key constraints placed on Counties.&nbsp;
Therefore, Pg will not let me 'DELETE FROM Counties;", nor will it let
me "DROP TABLE Counties;"&nbsp; <br>
<br>
I'm perplexed.&nbsp; Can someone suggest how I can best get data from
Counties to look just like newCounties?<br>
