I'm a little baffled as to why this works:
CREATE TABLE #table1 (
LName VARCHAR(100),
FName VARCHAR(100),
City VARCHAR(100)
)
CREATE TABLE #table2 (
LName VARCHAR(100),
FName VARCHAR(100),
City VARCHAR(100),
Suffix VARCHAR(100)
)
INSERT INTO #table1 ( LName, FName, City ) VALUES ( 'DOE JR', 'JOHN',
'PHOENIX' )
INSERT INTO #table1 ( LName, FName, City ) VALUES ( 'GATES', 'BILL',
'REDMOND' )
INSERT INTO #table1 ( LName, FName, City ) VALUES ( 'GORE III', 'AL',
'BACKWOODS' )
INSERT INTO #table1 ( LName, FName, City ) VALUES ( 'BRADSHAW', 'TERRY',
'HOUSTON' )
INSERT INTO #table2 ( LName, FName, City, Suffix ) VALUES ( 'DOE', 'JOHN',
'PHOENIX', 'JR' )
INSERT INTO #table2 ( LName, FName, City, Suffix ) VALUES ( 'GATES', 'BILL',
'REDMOND', '' )
INSERT INTO #table2 ( LName, FName, City, Suffix ) VALUES ( 'GORE', 'AL',
'BACKWOODS', 'III' )
INSERT INTO #table2 ( LName, FName, City, Suffix ) VALUES ( 'BRADSAW',
'TERRY', 'HOUSTON', '' )
SELECT t1.*, t2.*
FROM #table1 t1
INNER JOIN #table2 t2 ON ( t1.LName = t2.LName + ' ' + t2.Suffix )
The join clause for GATES would equate to this
'GATES' = 'GATES '
the extra space would be added. Now I remember reading something along the
lines that spaces after a varchar datatype would not be used for something,
in this case it looks like comparing 'GATES' to 'GATES ' will return true.
Here's a test using the above temp tables
SELECT * FROM #table1 WHERE LName = 'GATES '
SELECT * FROM #table1 WHERE LName = 'GATES '
SELECT * FROM #table1 WHERE LName = ' GATES'
The first two return a row, the third doesn't. Interest, if a little
strange. Any one know why this happens?

That's a great idea, do the join on a calculated field!
ON OnlyLastName + ' ' + Suffix = LastNameAndSufix
Is that what you're suggesting? If so and it works, I like :O)

offhand
left join tabl2 on (table2.lastname = table1.lastname
or table2.lastname like table1.lastname + ' %')
or if you want to match both
left join table2 on (
(table2.lastname = table1.lastname and table2.suffix is null) or
(table2.lastname + ' ' + table2.suffix = table1.lastname))
This is sql server syntax... it's gonna be different for every db...
it's an ugly, PURE EVIL BLACK AS COAL schema you have for the data
there... I have to deal with those at my job too -- hate 'em...
