Concatenate two fields from two different tables SQL

Hello,

I would like to concatenate two fields from two different tables loaded from an SQL database.

In order to clarify, I am going to put an example:

Field1 from Table1

Field2 from Table2

What I want to obtain is a

Field3 that is Field1_Field2

I know if Field1 and Field2 comes from one table, the script would look like this:

LOAD Field1 &'_'& Field2

From whatever.database.Table1

But in the case of having two tables, I dont know how to proceed. I would appreciate so much if you can help me on this.

Best regards.

Hello!

You must have field in database , which associates Field1 with Field2.


You can do like this, but it doesn't make sense (for examle Paris concatenate with Spain):


Countries:

LOAD * INLINE [

    Country,values1

    USA,60

    Spain,70

    Italy,65

    France,68

];

Cities:

LOAD * INLINE [

    City,values2

    New York,5

    Madrid,3

    Milan,3

    Paris,7

];

TempTableOuterJoin:

LOAD

    Country

Resident Countries;

JOIN(TempTableOuterJoin)

LOAD

    City

Resident Cities;

NoConcatenate

TableOuterJoin:

LOAD

    City & '_' & Country,

    Country,

    City

Resident TempTableOuterJoin;

DROP TABLE TempTableOuterJoin;

We must create a new internal table QlikView or Qlik Sense that contains two fields with the correct data by connecting the two source tables SQL.

Thank you Anton for your quick response. Actually, I had another field that connected the two tables so the script you sent me also works but eliminating Noconcatenate line.
