需要实现：
if not exists(select * from ErrorConfig where Type='RetryWaitSeconds')
begin
insert into ErrorConfig(Type,Value1)
values('RetryWaitSeconds','3')
end
只能用：
insert into ErrorConfig(Type,Value1) select 'RetryWaitSeconds','3' where not exists(select * from ErrorConfig where Type='RetryWaitSeconds')因为 sqlite 中不支持SP
