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)

      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'

exec spGenInsertSQL  表名

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"
