Question

我需要使用源表中的数据加载维度表。我必须将一些列转换为不同的数据类型。我不确定如何正确设置我的代码或处理一些语法错误。

我需要将纬度和经度转换为地理类型。我还需要将时区从文本转换为整数。继承人正在进行的代码。

USE DBM298_DataMart;
GO

CREATE PROC Load_Dim_Aiports
AS
SET IDENTITY_INSERT Dim_Airports ON

BEGIN

INSERT INTO Dim_Airports

(AirportId, AirportName, City, Country, LatLong , Altitude, Timezone)

SELECT AirportId, AirportName,City,Country, Latitude, Longitude, Altitude, Timezone

FROM src_flights;
SET LatLong =  geography::Point(Latitude,Longitude,4326)

DECLARE @NegativeNumeric  INT

DECLARE @NegativeCharString VARCHAR(50)

SELECT @NegativeNumeric = -1 * CAST ( REPLACE(@NegativeCharString ,'-','') AS DECIMAL (10,2)

END

Answer 1

这样的事情怎么样：

USE DBM298_DataMart;
GO

CREATE PROC Load_Dim_Aiports
AS
SET IDENTITY_INSERT Dim_Airports ON

BEGIN

INSERT INTO Dim_Airports

(AirportId, AirportName, City, Country, LatLong , Altitude, Timezone)

SELECT AirportId, AirportName, City, Country, geography::Point(Latitude,Longitude,4326) as LatLong , Altitude, cast(Timezone as int) as Timezone 

FROM src_flights;

END

创建存储过程以将数据加载到维度表（带转换）
