I need some help with a query I am trying to formulate - here is the scenario - I have 2 tables Table A has a FK to Table B - I need data from Table A provided rows for that data exist in Table B so this query does the job

SELECT TableA.FK1 FROM TableA INNER JOIN TableB ON TableA.FK1 = TableB.FK1

Now once I have the common FK I need to pull some data from table B - TableB has FK's to 2 other tables - how do I write one query to get all the data I need i.e that from table A and table B ?

Thanks

Try:

SELECT TableC.Field1, TableD.Field1
FROM TableA
INNER JOIN TableB ON TableA.FK1 = TableB.FK1
INNER JOIN TableC ON TableB.FK2 = TableC.FK2
INNER JOIN TableD on TableB.FK3 = TableD.FK3

You can nest joins. Let's assume your other tables are TableC and TableD:

SELECT TableA.FK1, TableB.FK_C, TableB.FK_D
FROM TableA INNER JOIN TableB ON TableA.FK1 = TableB.FK1
    INNER JOIN TableC ON TableB.FK_C = TableC.FK_C
    INNER JOIN TableD ON TableB.FK_D = TableD.FK_D

You can just add the TableB columns as a comma separated list between the SELECT and FROM

SELECT
TableA.FK1,
TableB.FK1
FROM TableA
INNER JOIN TableB ON TableA.FK1 = TableB.FK1
