sqlserver查询表字段结构脚本

可以使用以下 T-SQL 脚本获取 SQL Server 数据库中表的字段结构：

SELECT 
    c.name AS '列名',
    t.Name AS '数据类型',
    c.max_length AS '最大长度',
    c.is_nullable AS '可空',
    ISNULL(i.is_primary_key, 0) AS '主键'
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('表名')

将 `表名` 替换为你要查询的表名，并执行该脚本即可。
