You only have one table listed. It should be:

SELECT * FROM `table1` JOIN `table2` ON `table1.field1` = `table2.field2`;

Open in new window

your quey misses some part.. it should look like this

FROM `table1` T
    JOIN `ClientSource` C ON T.`sourceID` = C.`ClientSource` ;  
beridius I think your problem is related to convertion..

see this code:

declare @ClientSource table (Int_column int)
declare @ClientDestination table (string_column varchar(50))

insert into @ClientSource select 1 union select 2 union select 3
insert into @ClientDestination select '1 text hello' union select '2 text goodbye'

FROM @ClientSource CS
    JOIN @ClientDestination CD ON CS.Int_column = CD.string_column


It will give an error like

Conversion failed when converting the varchar value '1 text hello' to data type int.

You need to cast the datatype to avoid the error;

FROM @ClientSource CS
    JOIN @ClientDestination CD  ON cast(CS.Int_column as varchar(50))= CD.string_column

This will solve the problem

which database system are you using ... they all have there own syntax styles...
beridiusAuthor Commented:
phpmyadmin (mysql)
so remove the ms sql server and database miscellaneous zones...

you query is mysql specific...

can you show us some example data for the two tables from your description of the problem
it isn't clear how the data is represented within the tables..

we also need to know the datatypes of the columns

It looks like tbl_source has sourceID values of 1, 2, 3, and 4. Are there records in tbl_client with clientID values that match (1, 2, 3, or 4)? Are you getting an error when you run the query with the corrected syntax?
beridiusAuthor Commented:
I just need the syntax to join the tables together (relationship)
Kim WalkerWeb Programmer/TechnicianCommented:
I think we're talking about two different things. I remember relationships from my old (very old) days of MS Access databases. I'm not even sure you can create relationships in MySQL. The example you provided in your initial comment is a select query that dynamically creates records in a temporary table where the fields in each record are joined from different tables and returns those records to you for further processing. Are you trying to get data from the MySQL database or are you trying to create a relationship between two tables in a MySQL database?
beridiusAuthor Commented:
The data was in ms access and I have moved it to mysql there were relationship between in ms access
I need away to replicate in mysql
Kim WalkerWeb Programmer/TechnicianCommented:
I don't know that relationships have any usefulness in MySQL. I haven't used them in nearly 10 years. Perhaps another expert will comment further.
Guy Hengel [angelIII / a3]Billing EngineerCommented:
in MySQL (MyISAM engine), relationships (foreign keys) are irrelevant, because they are not enforced (they are in InnoDB tables...)
however, JOIN does not need or require the foreign keys.

possibly you continue to post more of the sample data?
