自动生成INSERT语句的SQL存储过程
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 SET @sql ='select ''INSERT INTO [' + @tablename + ']' + LEFT(@sql, Len(@sql) - 1) + ') ' + LEFT(@sqlValues, Len(@sqlValues) - 4) + ')'' from ' + @tablename PRINT @sql EXEC (@sql) END
执行如下语句测试结果:
exec spGenInsertSQL test
把得到的insert语句Copy后放置在如下位置执行:
set Identity_Insert text on //insert 语句 set Identity_Insert test off
PS:有时生成SQL语句很长,采用文本方式显示时无法显示全部,通过如下方式调整:
在 SQL Server 查询窗口中单击右键-〉“查询选项”-〉在“查询选项”对话框中的“结果”下,单击“文本”-〉更改"每列中显示的最大数"
