在SQL Server数据库中,如果需要让INSERT语句自动生成,应该采用何种方法呢?下面就将为您介绍自动生成INSERT语句的SQL存储过程,供您参考。
这是建立一个存储过程,通过执行这个存储过程,将指定的数据表中的数据导成Insert语句形式
–这是一个可以将表中的数据自动生成INSERT语句的存储过程
–有个BUG,如果是自动增长列,数据也会被插入
–在查询分析器中执行完成后,可以从执行结果中自制出SQL脚本。
IF OBJECT_ID(‘spGenInsertSQL’,’P’) IS NOT NULL
DROP PROC spGenInsertSQL
GO
CREATE proc spGenInsertSQL (@tablename varchar(256))
as
begin
declare @sql varchar(8000)
declare @sqlValues varchar(8000)
set @sql =’ (‘
set @sqlValues = ‘values (”+’
select @sqlValues = @sqlValues + cols + ‘ + ”,” + ‘ ,@sql = @sql + ‘[‘ + name + ‘],’
from
(select case
when xtype in (48,52,56,59,60,62,104,106,108,122,127)
then ‘case when ‘+ name +’ is null then ”NULL” else ‘ + ‘cast(‘+ name + ‘ as varchar)’+’ end’
when xtype in (58,61)
then ‘case when ‘+ name +’ is null then ”NULL” else ‘+””””’ + ‘ + ‘cast(‘+ name +’ as varchar)’+ ‘+””””’+’ end’
when xtype in (167)
then ‘case when ‘+ name +’ is null then ”NULL” else ‘+””””’ + ‘ + ‘replace(‘+ name+’,””””,””””””)’ + ‘+””””’+’ end’
when xtype in (231)
then ‘case when ‘+ name +’ is null then ”NULL” else ‘+”’N””” + ‘ + ‘replace(‘+ name+’,””””,””””””)’ + ‘+””””’+’ end’
when xtype in (175)
then ‘case when ‘+ name +’ is null then ”NULL” else ‘+””””’ + ‘ + ‘cast(replace(‘+ name+’,””””,””””””) as Char(‘ + cast(length as varchar) + ‘))+””””’+’ end’
when xtype in (239)
then ‘case when ‘+ name +’ is null then ”NULL” else ‘+”’N””” + ‘ + ‘cast(replace(‘+ name+’,””””,””””””) as Char(‘ + cast(length as varchar) + ‘))+””””’+’ end’
else ”’NULL”’
end as Cols,name
from syscolumns
where id = object_id(@tablename)
) T
set @sql =’select ”INSERT INTO [‘+ @tablename + ‘]’ + left(@sql,len(@sql)-1)+’) ‘ + left(@sqlValues,len(@sqlValues)-4) + ‘)” from ‘+@tablename
print @sql
exec (@sql)
end
GO
执行如下语句测试结果:
exec spGenInsertSQL test
