When encountering the error 22014: Invalid Argument for NTILE Function in Postgres, the user should immediately check the argument passed to the NTILE function in their query. The argument for NTILE must be a positive integer. Here are the steps to investigate and resolve the issue:
Example Query Adjustment:
If the original query was something like:
SELECT NTILE(your_variable_or_expression) OVER (ORDER BY your_column) FROM your_table;
Ensure your_variable_or_expression
evaluates to a positive integer. If you're unsure of what it evaluates to, you can run a test query like:
SELECT your_variable_or_expression FROM your_table LIMIT 1;
Adjust your_variable_or_expression
accordingly based on its output or replace it with a static positive integer for testing purposes:
SELECT NTILE(1) OVER (ORDER BY your_column) FROM your_table;
This will help identify if the issue is with the NTILE argument.
