Hi Sruthi,

Below I have given a script which can be executed in QV Script. Here I have taken 3 tables

1) Customer order lines

2) Item master file

3) Customer master

I have performed joining among these 3 tables and even I have given script for preceding load in QV also.

Please let me know for any help.


Load [Customer order number],

      [Item number],

      [Item name],

      [Customer number],

      [Customer number],

      [Entry date];

SELECT M.[Customer order number],

       M.[Item number],

       L.Name [Item name],

       M.[Customer number],

       C.[Customer name],

       M.[Entry date]

FROM DBO.[Customer order lines] M --Table 1

LEFT OUTER JOIN DBO.[Item master file] L on --Table 2

L.[Item number] = M.[Item number]

LEFT OUTER JOIN dbo.[Customer master] C on --Table 3

C.[Customer number] = M.[Customer Number];

Hi Sruthi,

Their are many types of join left,right, inner etc you have not mentioned the exact requirement.

Try like this:

Select * from

table1 t1 left join table2 t2 left join table3 t3

on t3.common_key_between_table2_table3=t2.common_key_between_table2_table3

on t2.common_key_between_table2_table1=t1.common_key_between_table2_table1
