在IMPALA中将科学记数法更改为整数

Question

如何在Impala SQL中将custno：5.0256926E7转换为正常的整数/数字？

这是我迄今为止所尝试过的：

SELECT * FROM z9_strategy.dstool_model_data_m 
WHERE snapshot_date_key = 20170630 
  AND custtype_ind = 1 
  AND retailer_retail = 1 
  AND CAST((custno AS FLOAT) AS int);

我也试过SELECT CAST(CAST(custno AS FLOAT) AS int)

Answer 1

使用CAST：

CAST(custno AS int);
