Known Causes

3 known causes

⚠️

Percentage Value Out of Range

The specified percentage for the `TABLESAMPLE` clause (e.g., `BERNOULLI(percentage)`) must be a numeric value between 0 and 100, inclusive. Values outside this range will trigger this error.

⚠️

Non-Numeric or Missing Percentage

The `TABLESAMPLE` clause requires a valid numeric percentage argument. Providing a non-numeric value, an incorrectly formatted number, or omitting the percentage entirely will lead to this error.

⚠️

Invalid REPEATABLE Seed

If using the `REPEATABLE` clause with `TABLESAMPLE`, its argument must be a valid integer seed. Supplying a non-integer value or using incorrect syntax for the seed will cause an invalid argument error.
