You can use Temporary table. You could create a temporary table with one column containing the condition values and then use it to update your main table. This approach can be more flexible and cleaner than writing a script with multiple update statements.
-- Create a temporary table with one column containing the condition values CREATE TEMPORARY TABLE temp_conditions (condition_value TEXT);
-- Insert the condition values into the temporary table INSERT INTO temp_conditions (condition_value) VALUES ('value1'), ('value2'), ('value3'), -- Add more values as needed... ('value295');
-- Update the boolean column based on the condition values UPDATE your_table SET boolean_column = true WHERE condition_column IN (SELECT condition_value FROM temp_conditions);
-- Clean up: drop the temporary table DROP TABLE IF EXISTS temp_conditions;
I have a table with 3492 rows. I want to update a boolean column from 'false' to 'true' for 295 rows based on the value of another column.
Is there a way to access a file with those condition values? If not, should I create a temporary table with one column containing those values, or do I write a psql script with 295 lines, one for each row to be updated?
