I think you need something along the lines of:
Select fieldlist
FROM company_table INNER JOIN slow_stream ON company_table.Name =
slow_stream.company_name
INNER JOIN medium_stream ON company_table.Name = medium_stream.company_name
INNER JOIN fast_stream ON company_table.Name = fast_stream.company_name
Note that that will only return records if there is a match between all 4
tables. if you want to return all records from the company_table,
regardless of whether there is a match in the other tables, you'd use:
Select fieldlist
FROM company_table LEFT OUTER JOIN slow_stream ON company_table.Name =
slow_stream.company_name
LEFT OUTER JOIN medium_stream ON company_table.Name =
medium_stream.company_name
LEFT OUTER JOIN fast_stream ON company_table.Name = fast_stream.company_name

Subject: SQL Joins.
Hello folks,
I ma having a spot of bother with joining tables in a query and could do
with some advice.
There are 4 tables: company_table, slow_stream, medium_stream and
fast_stream
Company table holds: company ID, name.
The other tables also have a company_name field.
I want to join all the tables together on the name field to give me one
virtual table.
What is the best way to go about this, I have tried in a number of ways.
