Error message

The decimal column {} type decimal({},{}) is out of range, which is precision less than 0, it will be converted to decimal({},{})

What it means

Warning from YashanDbTypeConverter.reconvert when a DECIMAL column has precision <= 0, which YashanDB cannot represent. The converter substitutes DEFAULT_PRECISION/DEFAULT_SCALE and logs; no exception is raised.

Solutions

1. Fix the source schema so the decimal has a valid precision (>= 1).
2. Explicitly define the target YashanDB column as DECIMAL(p,s) with correct precision.
3. Verify upstream connector metadata (JDBC driver precision reporting) is correct.

Example fix

// before: decimal(0,0)
// after
SQL: CAST(amount AS DECIMAL(38,10)) AS amount

DecimalType d = (DecimalType) col.getDataType();
if (d.getPrecision() <= 0) {
    col = col.copy().setDataType(new DecimalType(DEFAULT_PRECISION, DEFAULT_SCALE)).build();
}

boolean validPrecision(DecimalType d) { return d.getPrecision() > 0; }

When it happens

Trigger: Sink write to YashanDB where the incoming column is DecimalType with precision 0 or negative (typically from a broken or degenerate schema inference upstream).

Common situations: Schema inferred from bad metadata (some drivers return precision 0); hand-written catalog definitions with decimal(0,s); auto table creation from a corrupted source schema.
