Incorrect syntax near the keyword 'end'

Question

Can anyone help me out?

I don't know why the following SQL gives a syntax error:

if not exists (select 1 from sysobjects where type='U' and name='pg_result')
    create table pg_result (parent char(10), child char(10)) 
else
    delete from pg_result
end if

I'm getting the following error:

[Error] Script lines: 141-146

Incorrect syntax near the keyword 'end'.

Msg: 156, Level: 15, State: 2

Server: SYBDEV, Line: 5

I'm running:

Any ideas please?

Answer 1

try

if not exists (select 1 from sysobjects where type='U' and name='pg_result')
    create table pg_result (parent char(10), child char(10)) 
else
    delete from pg_result

or

if not exists (select 1 from sysobjects where type='U' and name='pg_result')
begin
    create table pg_result (parent char(10), child char(10)) 
end
else
begin
    delete from pg_result
end

You don't need the end if you don't use a begin
