Question

我正在尝试重命名列名，以帮助将数据库中的数据映射到另一个数据库以进行数据推送。

我需要做的是将StdType的名称更改为IncomeType，但无论我尝试什么，它都不会更改结果中的列名。

这是我的SQL查询：

SELECT
    'AA' + CAST(ClientID AS VARCHAR) AS AAID, 
    Description, 
    Convert(Money,Amount)/100 AS Amount, 
    Note, 
    StdType FROM [Finstat_Income] AS IncomeType
INNER JOIN #Assessments A
    ON 'AA' + CAST(ClientID AS VARCHAR) = A.AAID

#Assessments是一个临时表，它确实存在并适用于我的其他查询。

Finstat_Income是一个表而不是视图。我也尝试过使用和不使用方括号的查询，但没有区别。

结果输出为：

AAID | Description | Amount | Note | StdType

我想要的输出是：

AAID | Description | Amount | Note | IncomeType

Answer 1

您正在对表进行别名，而不是列。试试这个 -

SELECT
    'AA' + CAST(ClientID AS VARCHAR) AS AAID, 
    Description, 
    Convert(Money,Amount)/100 as Amount, 
    Note, 
    StdType AS IncomeType
FROM [Finstat_Income] 
INNER JOIN #Assessments A
    ON 'AA' + CAST(ClientID AS VARCHAR) = A.AAID

Answer 2

将别名放在列名旁边。

SELECT
'AA' + CAST(ClientID AS VARCHAR) AS AAID, 
Description, 
Convert(Money,Amount)/100 AS Amount, 
Note, 
StdType AS IncomeType
FROM [Finstat_Income] 
INNER JOIN #Assessments A ON 'AA' + CAST(ClientID AS VARCHAR) = A.AAID

Answer 3

也许这个

SELECT
'AA' + CAST(ClientID AS VARCHAR) AS AAID, 
Description, 
Convert(Money,Amount)/100 as Amount, 
Note, 
StdType as [IncomeType] FROM [Finstat_Income] AS IncomeType
INNER JOIN #Assessments A
ON 'AA' + CAST(ClientID AS VARCHAR) = A.AAID

SQL Server列别名无效
