Linking data from two different tables

Question

Linking data from two different tables

Navigation

0

I have two database tables one client call, another municipality, and in the table "client" I have the items (CdClient, NmClient, Status and CdMunicipio), in the "municipality" table I have (CdMunicipio and NmMunicipio).

I want to make a link only in the "CdMunicipio" item in the client table, so when I click on the code of any municipality in the client table, it automatically adds me the municipality that contains this code in the "municipality" table. These tables are from a Java project with JDBC / JSF, PrimeFaces.
