今天用友软件免费下载网站要给大家分享一段SQL代码,主要用于检测用友软件的数据库是否有特殊字符?例如说TAB键,空格,特殊符号等,可直接用于检测,废话不多说,直接上源SQL代码,大家自己尝试使用吧!
-----检测表中特殊字符,如tab、换行符、回车符--- ------将wa_gzdata替换成要检查的表名即可 ---- ------将有特殊字符的列存放在tmp_aa临时表中 go if exists(select * from sysobjects where name='tmp_aa' and xtype='U') drop table tmp_aa go CREATE TABLE tmp_aa( a varchar(20), b varchar(20)) go declare @tablename varchar (50) set @tablename='wa_gzdata' declare my_cur cursor for select name from syscolumns where id = object_id(@tablename) and xtype in (167,175,239,99)--nvarchar,varchar,char,nchar型 open my_cur declare @col_ls nvarchar(50) fetch next from my_cur into @col_ls while @@fetch_status=0 BEGIN declare @sql1 varchar(1000),@ls_where varchar(100),@ls_set varchar(100) declare @sql2 varchar(1000) declare @sql3 varchar(1000) --检测tab键 select @sql1 = 'select '+@col_ls+' from '+@tablename +' where CHARINDEX(CHAR(9),'+@col_ls+')>0' set @ls_where=' where CHARINDEX(CHAR(9),'+@col_ls+')>0' select @sql1 = 'select '+@col_ls+' from '+@tablename +@ls_where EXEC(@sql1) --------替换tab if @@ROWCOUNT>0 begin insert into tmp_aa (a,b) values (@col_ls,'tab键') set @sql1='update'+@tablename +' set ' +@col_ls+'=' set @ls_set='REPLACE('+@col_ls+',char(9),'+''''+''''+')' select @sql2= 'update '+ @tablename+ ' set ' +@col_ls+'='+@ls_set+@ls_where --print @sql2 exec(@sql2) end set @sql1='' --char(10)检测换行 select @sql1 = 'select '+@col_ls+' from '+@tablename +' where CHARINDEX(CHAR(10),'+@col_ls+')>0' set @ls_where=' where CHARINDEX(CHAR(10),'+@col_ls+')>0' select @sql1 = 'select '+@col_ls+' from '+@tablename +@ls_where --print @sql1 EXEC(@sql1) if @@ROWCOUNT>0 begin insert into tmp_aa (a,b) values (@col_ls,'换行符') set @sql1='update'+@tablename +' set ' +@col_ls+'=' set @ls_set='REPLACE('+@col_ls+',char(10),'+''''+''''+')' select @sql2= 'update '+ @tablename+ ' set ' +@col_ls+'='+@ls_set+@ls_where -- print @sql2 exec(@sql2) end set @sql1='' --- --char(13)检测回车键 select @sql1 = 'select '+@col_ls+' from '+@tablename +' where CHARINDEX(CHAR(10),'+@col_ls+')>0' set @ls_where=' where CHARINDEX(CHAR(10),'+@col_ls+')>0' select @sql1 = 'select '+@col_ls+' from '+@tablename +@ls_where --print @sql1 EXEC(@sql1) if @@ROWCOUNT>0 begin insert into tmp_aa (a,b) values (@col_ls,'回车键') set @sql1='update'+@tablename +' set ' +@col_ls+'=' set @ls_set='REPLACE('+@col_ls+',char(13),'+''''+''''+')' select @sql2= 'update '+ @tablename+ ' set ' +@col_ls+'='+@ls_set+@ls_where --print @sql2 exec(@sql2) end fetch next from my_cur into @col_ls END close my_cur DEALLOCATE my_cur
