为了避免某些列的重复行，请使用user_type_id而不是system_type_id。

SELECT 
    c.name 'Column Name',
    t.Name 'Data type',
    c.max_length 'Max Length',
    c.precision ,
    c.scale ,
    c.is_nullable,
    ISNULL(i.is_primary_key, 0) 'Primary Key'
FROM    
    sys.columns c
INNER JOIN 
    sys.types t ON c.user_type_id = t.user_type_id
LEFT OUTER JOIN 
    sys.index_columns ic ON ic.object_id = c.object_id AND ic.column_id = c.column_id
LEFT OUTER JOIN 
    sys.indexes i ON ic.object_id = i.object_id AND ic.index_id = i.index_id
WHERE
    c.object_id = OBJECT_ID('YourTableName')

只需将YourTableName替换为实际的表名-适用于SQL Server 2005及更高版本。

如果您正在使用模式，请将YourTableName替换为YourSchemaName。YourTableName，其中YourSchemaName是实际的模式名，YourTableName是实际的表名。

扩展Alex的答案，您可以这样做以获得PK约束

Select C.COLUMN_NAME, C.DATA_TYPE, C.CHARACTER_MAXIMUM_LENGTH, C.NUMERIC_PRECISION, C.IS_NULLABLE, TC.CONSTRAINT_NAME
From INFORMATION_SCHEMA.COLUMNS As C
    Left Join INFORMATION_SCHEMA.TABLE_CONSTRAINTS As TC
      On TC.TABLE_SCHEMA = C.TABLE_SCHEMA
          And TC.TABLE_NAME = C.TABLE_NAME
          And TC.CONSTRAINT_TYPE = 'PRIMARY KEY'
Where C.TABLE_NAME = 'Table'

我一定是错过了您想要一个标记来确定给定的列是否是PK的一部分，而不是PK约束的名称。你可以用:

Select C.COLUMN_NAME, C.DATA_TYPE, C.CHARACTER_MAXIMUM_LENGTH
    , C.NUMERIC_PRECISION, C.NUMERIC_SCALE
    , C.IS_NULLABLE
    , Case When Z.CONSTRAINT_NAME Is Null Then 0 Else 1 End As IsPartOfPrimaryKey
From INFORMATION_SCHEMA.COLUMNS As C
    Outer Apply (
                Select CCU.CONSTRAINT_NAME
                From INFORMATION_SCHEMA.TABLE_CONSTRAINTS As TC
                    Join INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE As CCU
                        On CCU.CONSTRAINT_NAME = TC.CONSTRAINT_NAME
                Where TC.TABLE_SCHEMA = C.TABLE_SCHEMA
                    And TC.TABLE_NAME = C.TABLE_NAME
                    And TC.CONSTRAINT_TYPE = 'PRIMARY KEY'
                    And CCU.COLUMN_NAME = C.COLUMN_NAME
                ) As Z
Where C.TABLE_NAME = 'Table'

select
      c.name as [column name], 
      t.name as [type name],
      tbl.name as [table name]
from sys.columns c
         inner join sys.types t 
      on c.system_type_id = t.system_type_id 
         inner join sys.tables tbl
      on c.object_id = tbl.object_id
where
      c.object_id = OBJECT_ID('YourTableName1') 
          and 
      t.name like '%YourSearchDataType%'
union
(select
      c.name as [column name], 
      t.name as [type name],
      tbl.name as [table name]
from sys.columns c
         inner join sys.types t 
      on c.system_type_id = t.system_type_id 
         inner join sys.tables tbl
      on c.object_id = tbl.object_id
where
      c.object_id = OBJECT_ID('YourTableName2') 
          and 
      t.name like '%YourSearchDataType%')
union
(select
      c.name as [column name], 
      t.name as [type name],
      tbl.name as [table name]
from sys.columns c
         inner join sys.types t 
      on c.system_type_id = t.system_type_id 
         inner join sys.tables tbl
      on c.object_id = tbl.object_id
where
      c.object_id = OBJECT_ID('YourTableName3') 
          and 
      t.name like '%YourSearchDataType%')
order by tbl.name

根据一个数据库中三个不同表的搜索数据类型，搜索哪个列在哪个表中。这个查询可以扩展到'n'个表。

查询:执行sp_description _first_result_set并选择年收入 [DB_NAME]。[DBO]。(员工)”

注意:在某些ide中选择n之前是工作的，或者在某些ide中没有选择n是工作的

Marc_s的答案很好，但如果主键列出现在其他索引中，这些列会出现不止一次，那么它就有一个缺陷。如。

演示:

create table dbo.DummyTable
(
    id int not null identity(0,1) primary key,
    Msg varchar(80) null
);

create index NC_DummyTable_id ON DummyTable(id);

下面是我用来解决这个问题的存储过程:

create or alter procedure dbo.GetTableColumns
(
    @schemaname nvarchar(128),
    @tablename nvarchar(128)
)
AS
BEGIN
    SET NOCOUNT ON;

    with ctePKCols as
    (
        select 
            i.object_id,
            ic.column_id
        from 
            sys.indexes i
            join sys.index_columns ic ON i.object_id = ic.object_id AND i.index_id = ic.index_id
        where 
            i.is_primary_key = 1
    )
    SELECT
        c.name AS column_name,
        t.name AS typename,
        c.max_length AS MaxLength,
        c.precision,
        c.scale,
        c.is_nullable,
        is_primary_key = CASE WHEN ct.column_id IS NOT NULL THEN 1 ELSE 0 END
    FROM 
        sys.columns c
        JOIN sys.types t ON t.user_type_id = c.user_type_id
        LEFT JOIN ctePKCols ct ON ct.column_id = c.column_id AND ct.object_id = c.object_id
    WHERE 
        c.object_ID = OBJECT_ID(quotename(@schemaname) + '.' + quotename(@tablename))
    
END 
GO

exec dbo.GetTableColumns 'dbo', 'DummyTable'

我有点惊讶居然没人提

sp_help 'mytable'
