I'm trying to check for condition If the vale is one string values then something, else if other string value then some other thing. My quest is like this

SQL

CREATE PROCEDURE GetMemberManagement

@UserId varchar(100)

AS

BEGIN

declare @membertype varchar(100)
set @membertype= CAST((select b.membertypename from users a left join membertypes b on a.membertype=b.membertype where
a.userid = @UserId)

if @membertype = 'Advisor'
BEGIN
select b.fullname,c.membertypename,a.rankno,d.rankname from users a left join profiles b on a.accountid=b.accountid
left join membertypes c on a.membertype=c.membertype left join ranks d on a.rankno=d.rankno
where a.userid=@UserId
END

else if @membertype = 'Agent'
BEGIN
select b.fullname,c.membertypename,a.rankno,d.rankname from users a left join profiles b on a.accountid=b.accountid
left join membertypes c on a.membertype=c.membertype left join ranks d on a.rankno=d.rankno
where a.userid=@UserId
END

END

Here i'm getting error like this

Msg 156, Level 15, State 1, Procedure GetMemberManagement, Line 13
Incorrect syntax near the keyword 'if'.

So How can I fix this problem?

CAST requires a destination type:

SQL

...
set @membertype= CAST(
                   (select b.membertypename from users a left join membertypes b on a.membertype=b.membertype where a.userid = @UserId) 
                 as varchar(100))
...
