我刚刚做了marc_s“presentation ready”:

SELECT 
    c.name 'Column Name',
    t.name 'Data type',
    IIF(t.name = 'nvarchar', c.max_length / 2, c.max_length) 'Max Length',
    c.precision 'Precision',
    c.scale 'Scale',
    IIF(c.is_nullable = 0, 'No', 'Yes') 'Nullable',
    IIF(ISNULL(i.is_primary_key, 0) = 0, 'No', 'Yes') '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')

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

我有点惊讶居然没人提

sp_help 'mytable'

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。

存储过程sp_columns返回详细的表信息。

exec sp_columns MyTable
