I have a table that has 3 columns
id  parentid  tText
1     NULL     Lottery
2       1             SubText
3        1           MoreText
4       Null        Structured
5         4           SMenu
I need to have a select statement tat gives me the number of records that a parent (id where parentid=null) has

So my select based on the data above would be

id     tText       numRecords
1      Lottery         2
4      Structured    1

Close enough...added a line and works great

select t1.id, t1.ttext, count(*) numRecords
from dbo.valueReportsCrystal t1 left join dbo.valueReportsCrystal t2 on t1.id = t2.parentid
where t1.parentID is null
group by t1.id, t1.ttext
