使用此查询获取Schema, Table, Column,Type, max_length, is_nullable

SELECT QUOTENAME(SCHEMA_NAME(tb.[schema_id])) AS 'Schema'
    ,QUOTENAME(OBJECT_NAME(tb.[OBJECT_ID])) AS 'Table'
    ,C.NAME as 'Column'
    ,T.name AS 'Type'
    ,C.max_length
    ,C.is_nullable
FROM SYS.COLUMNS C INNER JOIN SYS.TABLES tb ON tb.[object_id] = C.[object_id]
    INNER JOIN SYS.TYPES T ON C.system_type_id = T.user_type_id
WHERE tb.[is_ms_shipped] = 0
ORDER BY tb.[Name]

在TSQL/MSSQL中，它看起来像:

SELECT t.name, c.name 
FROM sys.tables t 
JOIN sys.columns c ON t.object_id = c.object_id
JOIN sys.types y ON y.user_type_id = c.user_type_id
WHERE t.name = ''

这同样适用于只选择列名及其各自的字符类型

SELECT COLUMN_NAME ,DATA_TYPE 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE TABLE_NAME = 'Items';   

如果有人觉得这个有用的话。在SQL Server中:

      sp_columns 'yourtablename'

这将给出所有列的详细信息。它提供了column_name、data_type、type_name、precision、length、iss_nullable等。

在vb60中，你可以这样做:

Public Cn As ADODB.Connection
'open connection
Dim Rs As ADODB.Recordset
 Set Rs = Cn.OpenSchema(adSchemaColumns, Array(Empty, Empty, UCase("Table"), UCase("field")))

'和sample (valRs是rs.fields("CHARACTER_MAXIMUM_LENGTH").value的函数):

 RT_Charactar_Maximum_Length = (ValRS(Rs, "CHARACTER_MAXIMUM_LENGTH"))
        rt_Tipo = (ValRS(Rs, "DATA_TYPE"))

使用这个查询

SELECT * FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'TABLE_NAME'
ORDER BY ORDINAL_POSITION
