Find Tables or Columns by Name, and or Search all views functions or sprocs for a piece of text

This is my most used snippet in "kv" (key value snippet storer). "kv sysc"

Select distinct 'sp_helptext ''' + Schema_Name(UID) + '.' + so.Name + '''
go' from sysobjects so inner join syscomments sc on so.id = sc.id where sc.text like
'%%'

Similarly, here's a query to find objects by name (so) —

Select Schema_Name(UID) + '.' + Name , Xtype
from sysobjects
where
xtype = 'U' AND Schema_Name(UID) + '.' + Name like
'%%'

And one to find columns (sc) —

Select sc.Name as [Column], Schema_Name(so.UID) + '.' + so.Name as [Table], so.Xtype
from sysobjects so
inner join syscolumns sc on so.id = sc.id
where so.xtype in ('U','V') AND Schema_Name(so.UID) + '.' + so.Name  like
'%%'
--and sc.Name like '%%'

And here's commands to add them to kv —

kv sysc "Select distinct 'sp_helptext ''' + Schema_Name(UID) + '.' + so.Name + '''
go' from sysobjects so inner join syscomments sc on so.id = sc.id where sc.text like
'%%'"

kv so "Select Schema_Name(UID) + '.' + Name , Xtype
from sysobjects
where
xtype in ('U','V','P') AND Schema_Name(UID) + '.' + Name like
'%%'"

kv sc "Select sc.Name as [Column], Schema_Name(so.UID) + '.' + so.Name as [Table], so.Xtype
from sysobjects so
inner join syscolumns sc on so.id = sc.id
where
--so.xtype in ('U','V') AND Schema_Name(so.UID) + '.' + so.Name like '%%'
--and
--sc.Name like '%%'"

Here's a command to list all objects that have definitions, along with their definition:

Select
	schema_name(so.uid) + '.' + so.[name]  AS [Schema.Object],
	so.xtype,
	Definitions.Definition,
	len(Definitions.Definition) as [Length of definition],
	master.dbo.fn_varbintohexstr(hashbytes('MD5', Definitions.Definition)) as Hasho
from
sysobjects so
outer apply (Select stuff((select '' + sc.text
					from syscomments  sc
				where sc.id = so.id
				order by colid
				for xml path , TYPE).value('.[1]','nvarchar(max)'
			), 1, 1, '') as Definition) as Definitions
where Definitions.Definition is not null

Notice I've combined it with hashbytes for easy difference checking/comparison of objects.
