When encountering the error 2202G: Invalid Tablesample Repeat from a PostgreSQL database, the immediate action you should take is:
TABLESAMPLE clause. This error typically indicates an issue with how the TABLESAMPLE method is used, possibly with the REPEATABLE argument.TABLESAMPLE Syntax: Ensure the syntax of the TABLESAMPLE clause is correct. The syntax should follow the pattern:SELECT * FROM table_name TABLESAMPLE sampling_method (percentage) REPEATABLE (seed)
sampling_method is valid (e.g., BERNOULLI, SYSTEM), the percentage is properly defined, and the seed in the REPEATABLE argument is a positive integer.REPEATABLE argument, ensure the seed value provided is a positive integer. A negative value or a value that is not an integer can cause this error.REPEATABLE: If you're unsure about the REPEATABLE seed value, try running the query without the REPEATABLE argument to check if the error persists. This can help narrow down the issue to the REPEATABLE argument:SELECT * FROM table_name TABLESAMPLE sampling_method (percentage)
TABLESAMPLE and the REPEATABLE keyword for additional insights.Remember, without a database administrator, proceed with caution and ensure you have the proper backups or permissions before making significant changes to the database or its queries.
