SQL Data Report

SUGGESTED

I am trying to pull data from three tables but running into a relation issues. Table1: Customer Table. Table 2: Invoice Table Table 3: Invoice Detail Table On table 1 the customer number column is "BPCNUM_0" On Table 2: The customer number column is "BPR_0" On Table 3: The customer number column is "BPCINV_0" Any idea how I can connect them to pull the data?

What would be the SQL query to connect them to be able to pull the data?
