How to link all fields from different tables

[#1]

For example I have two tables

Table1:

Load id, name, group1, group2 from file1.csv

Table2:

Load id, name, group1, group3 from file2.csv

Automatically QV do SynLink by id, name and group1. When I select in List box of group2 anything, then any choice of "List box" group3 is not active. Also joining that tables don't solve this problem. Is it possible to do it active?

Hi Sergei,

You can try the following:

Table1:

Load id, name, group1, group2, 'none' as group3 from file1.csv;

Table 2:

Load id, name, group1, 'none' as group2, group3 from file2.csv;

This will concatenate both tables.

I hope this help you.

Best regards.

Hi Miguel! Thank you for Your quick reply.

I thnik my example was not very correct, so I try to do another one:

Table1:

Load id, name, group1, group2, 2009 as year from file1.csv

Table2:

Load id, name, group2, 2010 as year from file2.csv

Table3:

Load id, name, group1, 2010 as year from file3.scv

Here I want to link group1 from Table3 with group2 from Table2, when id is the same. But 'none' value is not suitable, because I have real values of group1 in Table3.

Hi Sergei,

Based in your example, your code must be the following:

FinalTable:
// Table3
Load Id, Name, Group1, 2010 as Year from File3.scv;
Left join
// Table2
Load Id, Name, Group2, 2010 as Year from File2.scv

The join will be done through Id, Name and Year fields, but the field Group2 will be null where the join isn't possible. If you want a exactly join, use the Inner sentence.

I hope this helps you.

Best regards.
