Row | Violation |
---|---|
1 | Unmatched statement result.addAll(Arrays.asList(getColumnNullableAlterSQL(column,false,qualifier,prefs))); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
2 | Unmatched statement columnNotNullAlters.add(DialectUtils.getColumnNullableAlterSQL(column,false,this,alterClause,specifyColumnType,qualifier,prefs)); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
