批量生成insert 语句的存储过程
今天做了一个将表中数据导出,生成xml文件的需求。在网上找了几个存储过程:
生成表中所有数据的insert 语句的存储过程:
--exec spGenInsertSQL 'tabelname'
create proc [dbo].[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
print @sqlValues
set @sql ='select ''INSERT INTO '+ @tablename + left(@sql,len(@sql)-1)+') ' + left(@sqlValues,len(@sqlValues)-4) + ')'' as sql from '+@tablename

print @sql
exec (@sql)
end



批量生成查询条件下的insert语句:
/*
Authore : neeraj prasad sharma (please dont remove this :))
Example (1) Exec [dbo].[INS]  'Dbo.test where 1=1'
        (2) Exec [dbo].[INS]  'Dbo.test where name =''neeraj''' * for string
	 (3) Exec [dbo].[INS]  'Dbo.test where createdate>''2013-09-20'''

here Dbo is schema and test is tablename and 1=1 is condition
