SQL Server Query

I am trying to write a query on SQL Server to display results from 3 tables, called:
Table1, Table2 and Table3
WHERE Table1.ColumnA='x' and Table2.ColumnB='y' and Table3.columnC='z'
Any ideas?   Thanks.

do you have a common column to join between these 3 tables?

Yes there is an ID column listed in all 3 tables.

select t2.id, t2.loginname,t2.wrknum,t1.time,t3.description
from table2 t2
inner join table1 t1 on t1.id=t2.id
inner join table3 t3 on t3.id=t2.id

select t1.ColumnA,t2.ColumnB,t3.ColumnC
from table1 t1,table2 t2,table3 t3
inner join table1 t1 on t1.id=t2.id
inner join table3 t3 on t3.id=t2.id

@ashok111.  I just realized this won't work. I need to filter for specific criteria in each column with the where clause (as posted in my original question).  
WHERE Table1.ColumnA='x' and Table2.ColumnB='y' and Table3.columnC='z'
Please advise how can I do this.

just add the filter as below...

select t1.ColumnA,t2.ColumnB,t3.ColumnC
from table1 t1,table2 t2,table3 t3
inner join table1 t1 on t1.id=t2.id
inner join table3 t3 on t3.id=t2.id
WHERE Table1.ColumnA='x' and Table2.ColumnB='y' and Table3.columnC='z'

it should be
select t1.ColumnA,t2.ColumnB,t3.ColumnC
from table1 t1,table2 t2,table3 t3
inner join table1 t1 on t1.id=t2.id
inner join table3 t3 on t3.id=t2.id
WHERE T1.ColumnA='x' and T2.ColumnB='y' and T3.columnC='z'

Is there way to write this without doing an alias name? I keep getting multiple syntax errors, no matter what I change I can't getting it when trying to follow the syntax logic above.
errors include:
The correlation name 'T1' has the same exposed name as table 'T1'.
or
The Table name T1 is specified multiple times in the FROM Clause
or
Msg 107, Level 16, State 2, Line 1
The column prefix 'T1' does not match with a table name or alias name used in the query.

When I remove all references to the alias names, I get the error:
Msg 107, Level 16, State 2, Line 1
The column prefix 'Table1' does not match with a table name or alias name used in the query.

try now...

select t1.ColumnA,t2.ColumnB,t3.ColumnC
from table1 t1,table2 t2,table3 t3
where t1.id = t2.id
and t2.id = t3.id
and T1.ColumnA='x'
and T2.ColumnB='y'
and T3.columnC='z'
