When encountering the error 22010: Invalid Indicator Parameter Value from a PostgreSQL database, follow these steps:
- Identify the Query Causing the Error: Review the application logs to find the specific query that triggered the error. This is crucial for understanding which part of your code is causing the issue.
- Examine the Query Parameters: Once you've identified the problematic query, closely examine the parameters being passed to it. Look for any values that might not match the expected format or data type expected by the database.
- Check Data Types in Your Schema: Use the
\d table_name
command in the psql
command-line interface to inspect the schema of the table involved in the query. Compare the data types of the columns with the types of the parameters you're passing in your query. Make sure they match. For example: \d your_table_name
- Run a Test Query in
psql
: Attempt to manually execute a simplified version of the problematic query directly in the psql
command-line interface, substituting any variables with hard-coded values. This can help isolate the issue by confirming whether the problem lies with the query logic itself or the way parameters are passed at runtime. - For example, if your original query was something like:
SELECT * FROM your_table WHERE your_column = :parameter;
- Replace
:parameter
with a literal value that you know is valid. - Validate Parameter Formatting: If your query involves date-time or numeric data types, ensure that the parameters passed are correctly formatted according to PostgreSQL's expected formats. For example, dates should typically be in the
YYYY-MM-DD
format. - Adjust the Query or Parameters Based on Findings: Based on your investigations, you may need to adjust the data types of the parameters being passed, correct the format of certain parameter values, or modify the query to ensure compatibility with the expected data types.
- Log Detailed Error Information: If possible, adjust your application's logging level to capture detailed error messages from PostgreSQL. This might provide further insights into why the parameter value is considered invalid.
- Consult PostgreSQL Documentation: If the cause of the error is still unclear, consult the PostgreSQL documentation regarding the specific function or feature you're attempting to use. There might be constraints or requirements for parameter values that are not immediately obvious.
By following these steps, you should be able to identify and correct the cause of the 22010: Invalid Indicator Parameter Value
error.
