Searching the postgresql doc for UPDATE the examples I find show updating
one or a few rows in a table. I have 457 rows to update in a table.
I could write a .sql script with 457 lines, each updating one row of the
table. My web search for `sql: update table rows from a file of column
values' finds pages for single row updates and updating a table from another
table, but neither is what I want.
I want to change a column value in a table based on the value of a different
column in that same table.
Specifically, in the 'people' table I want to change the column 'active'
from false to true for 457 specific person_id row numbers.
Is there a way to do this without manually writing 457 'update ...' rows in
a .sql file?
TIA,
Rich
