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]

在我的情况下，我需要获得动态SQL的数据类型(Shudder!)无论如何，这里是一个函数，我创建返回完整的数据类型。例如，它不会返回'decimal'，而是返回decimal (18,4): dbo。GetLiteralDataType

简单地这样做

describe table test.oim_test_2

您将获得所有列及其数据类型的详细信息

我认为在Microsoft SQL Server Management Studio中最简单和最有用的方法是:

EXEC [ServerName].[DatabaseName].dbo.sp_help 'TableName'

对于Apache Derby，如下面的答案所示:

select columndatatype from sys.syscolumns
  where referenceid = (
    select tableid from sys.systables
    where tablename = 'YOUR_TABEL_NAME'
    and columnname= 'YOUR_COLUMN_NAME')

对于IBM DB2:

SELECT TYPENAME FROM SYSCAT.COLUMNS WHERE TABSCHEMA='your_schema_name' AND TABNAME='your_table_name' AND COLNAME='your_column_name'
