網上現有的全庫查詢，無法識別自定義架構的數據庫結構：

declare @str nvarchar(10)
declare @tablename varchar(50)
declare @colname varchar(50)
declare @counts int
declare @sql nvarchar(2000)--以上定義變量
declare cur1 cursor for 
select a.name tablename,B.name colname from sys.objects a,syscolumns b where a.object_id=b.id and a.type_desc=
 
‘USER_TABLE‘--定義遊標
set @str=‘海‘ --設置要查找的字符
Open cur1 --打開遊標
Fetch next From cur1 Into @tablename,@colname
While(@@Fetch_Status = 0) --循環
Begin
set @sql=N‘select  @counts=COUNT(*) from ‘ + @tablename + ‘   where  charindex(‘‘‘+@str+‘‘‘,‘+@colname+‘)>0‘
exec sp_executesql @sql,N‘@counts int output
 
‘,@counts output --執行動態sql
if @counts>0 --判斷某個表某個字段是否存在特定字符
begin
print @tablename+‘,‘+@colname --打印表名及字段名
end
Fetch next From cur1 Into @tablename,@colname
End
Close cur1 --關閉遊標
Deallocate cur1 --釋放遊標

添加架構支持後，雖偶爾會有報錯，可查詢架構：

declare @str nvarchar(10)
declare @schemasname varchar(50)
 
declare @tablename varchar(50)
declare @colname varchar(50)
declare @counts int
declare @sql nvarchar(2000)--以上定義變量
declare cur1 cursor for 
select s.name schemasname,a.name tablename,B.name colname from sys.objects a,syscolumns b,sys.schemas s 
where a.object_id=b.id and a.schema_id=s.schema_id and a.type_desc=‘USER_TABLE‘--定義遊標
set @str=‘汙染‘ --設置要查找的字符
Open cur1 --打開遊標
Fetch next From cur1 Into @schemasname,@tablename,@colname
While(@@Fetch_Status = 0) --循環
Begin
set @sql=N‘select  @counts=COUNT(*) from ‘ + @schemasname + ‘.‘+ @tablename + ‘   where  charindex(‘‘‘+@str+‘‘‘,‘+@colname+‘)>0‘
exec sp_executesql @sql,N‘@counts int output‘,@counts output --執行動態sql
if @counts>0 --判斷某個表某個字段是否存在特定字符
begin
print @schemasname+‘,‘+@tablename+‘,‘+@colname --打印表名及字段名
end
Fetch next From cur1 Into @schemasname,@tablename,@colname
End
Close cur1 --關閉遊標
Deallocate cur1 --釋放遊標
