Try this

declare @table table (ad_str1 varchar(50))

insert @table

select 'apple avenue w' union all

select 'melon road e' union all

select 'watermelon circle n'union all

select 'banana durian crossing s'

select * from @table

UPDATE @Table

SET ad_Str1 = CASE WHEN CHARINDEX(' W',ad_str1) > 0 THEN REPLACE(ad_str1,' W',' internet')

ELSE CASE WHEN CHARINDEX(' e',ad_str1) > 0 THEN REPLACE(ad_str1,' e',' internet')

ELSE CASE WHEN CHARINDEX(' n',ad_str1) > 0 THEN REPLACE(ad_str1,' n',' internet')

ELSE CASE WHEN CHARINDEX(' s',ad_str1) > 0 THEN REPLACE(ad_str1,' s',' internet') ELSE ad_str1 END END END END

FROM @table

SELECT * FROM @Table

ELSE CASE WHEN CHARINDEX(' e',ad_str1) > 0 THEN REPLACE(ad_str1,' e','')

ELSE CASE WHEN CHARINDEX(' n',ad_str1) > 0 THEN REPLACE(ad_str1,' n','')

Sriram Ramamoorthy,

your query doesn't work

Server: Msg 170, Level 15, State 1, Line 15

Line 15: Incorrect syntax near ','.

Hello,

It is a syntax error.

Replace "Wink" face with ")", then it will work

There's probably a dozen ways... here's a couple without UDF or Tally table...

declare @table table (ad_str1 varchar(50))

insert @table

select 'apple avenue w' union all

select 'melon road e' union all

select 'watermelon circle n'union all

select 'banana durian crossing s'

If your strings never have more than 3 spaces and no periods, this works nasty fast...

SELECT PARSENAME(REPLACE(ad_str1,' ','.'),2)

FROM @table

If it has more than 3 spaces or contains periods, then this will work so long as the last two characters are a space followed by N, S, E, or W...

SELECT REVERSE(SUBSTRING(SUBSTRING(REVERSE(ad_strl),3,50),1,CHARINDEX(' ',SUBSTRING(REVERSE(ad_strl),3,50))))

FROM @table
