如何使用SQL Server中的命令行自动生成脚本？

Question

在SQL Server Management Studio中，有一个“生成并发布脚本向导”上下文菜单选项，可以自动为表数据生成插入语句脚本。

在我的情况下，我只能访问使用命令行的数据库查询。含义我无法访问“生成和发布脚本向导”。

使用纯SQL或T-SQL命令行可以实现类似的功能吗？

这是一个基本的SQL构建基于系统视图插入：

DECLARE @sqlinsert AS VARCHAR(MAX) = '' 
DECLARE @tbl AS VARCHAR(128)='dbo.mytable' 

SET @sqlinsert = 'DECLARE 
' 

SELECT @sqlinsert = @sqlinsert + ' 
@ins_' + c.name + ' ' + t.name 
+ IIF(t.max_length>=8000,'('+ CONVERT(VARCHAR(16),c.max_length) +')','')+ ','--c.column_id, c.name,c.system_type_id,t.name,c.max_length,t.max_length,c.* 
FROM sys.tables a 
JOIN sys.schemas b ON a.schema_id = b.schema_id 
JOIN sys.columns c ON c.object_id = a.object_id 
JOIN sys.types t ON t.system_type_id = c.system_type_id AND t.system_type_id <> 231 
WHERE b.name+'.'+a.name = @tbl 
AND is_rowguidcol = 0 AND is_identity = 0 AND is_computed = 0 
ORDER BY c.column_id 

SET @sqlinsert = SUBSTRING(@sqlinsert,1,LEN(@sqlinsert)-1) 

SET @sqlinsert = @sqlinsert + ' 
Insert Into ' + @tbl + ' (' 

SELECT @sqlinsert = @sqlinsert + ' 
[' + c.name + '],'--c.column_id, c.name,c.system_type_id,t.name,c.max_length,t.max_length,c.* 
FROM sys.tables a 
JOIN sys.schemas b ON a.schema_id = b.schema_id 
JOIN sys.columns c ON c.object_id = a.object_id 
JOIN sys.types t ON t.system_type_id = c.system_type_id AND t.system_type_id <> 231 
WHERE b.name+'.'+a.name = @tbl 
AND is_rowguidcol = 0 AND is_identity = 0 AND is_computed = 0 
ORDER BY c.column_id 

SET @sqlinsert = SUBSTRING(@sqlinsert,1,LEN(@sqlinsert)-1) 
SET @sqlinsert = @sqlinsert + ') 
Values (' 

SELECT @sqlinsert = @sqlinsert + ' 
@ins_' + c.name + ','--c.column_id, c.name,c.system_type_id,t.name,c.max_length,t.max_length,c.* 
FROM sys.tables a 
JOIN sys.schemas b ON a.schema_id = b.schema_id 
JOIN sys.columns c ON c.object_id = a.object_id 
JOIN sys.types t ON t.system_type_id = c.system_type_id AND t.system_type_id <> 231 
WHERE b.name+'.'+a.name = @tbl 
AND is_rowguidcol = 0 AND is_identity = 0 AND is_computed = 0 
ORDER BY c.column_id 

SET @sqlinsert = SUBSTRING(@sqlinsert,1,LEN(@sqlinsert)-1) 
SET @sqlinsert = @sqlinsert + ')' 

SELECT @sqlinsert 

--SELECT * FROM sys.types 

也许你可能需要一些更多的过滤器/如果你的表没有覆盖的专业阅读SYS意见的情况。
