遍历多个表，看某列是否存在？

Question

我有一个临时文件 table，其中包含 table 个名称的列表我需要遍历这些 table 以查看此列是否存在。如果不是，则在不存在的地方打印出 table

到目前为止我有

CREATE TABLE #ListOfTables (
   [TableName] varchar(max)
)
INSERT INTO #ListOfTables
   ([TableName])
  (SELECT TableName from dbo.CustomTableAttributes)

-- Statement
DECLARE @stm nvarchar(max)
SET @stm = N''

IF EXISTS(SELECT 1 FROM sys.columns 
          WHERE Name = N'BegDt'
 Errors Here --> AND Object_ID = Object_ID(N''+ ***Select [TableName] FROM #ListOfTables*** +''))

Begin
'Do Work here'
End

Answer 1

这应该 return 在 table 中没有名称为 'ID' 的列的所有 table。只需将 'ID' 更改为您需要的内容即可。

SELECT * 
FROM sys.tables TBL
-- this reverses the logic and returns all tables that do not exist in the below list
WHERE TBL.object_id NOT IN (
    -- this selects all the tables that have that column in the table structure
    SELECT TBL.object_id
    FROM sys.tables TBL
    INNER JOIN sys.columns COL ON TBL.object_id = col.object_id
    WHERE col.name = 'ID'
)

请尝试这样的操作

存在：

SELECT table_name 
    FROM INFORMATION_SCHEMA.COLUMNS 
    WHERE table_name in (SELECT TableName from dbo.CustomTableAttributes)
    AND column_name = 'BegDt'

不存在：

SELECT TableName from dbo.CustomTableAttributes
Except    
SELECT table_name 
    FROM INFORMATION_SCHEMA.COLUMNS 
    WHERE table_name in (SELECT TableName from dbo.CustomTableAttributes)
    AND column_name = 'BegDt'

遍历多个表，看某列是否存在？

Loop through multiple tables to see if a column exists?
