Comparar tablas

Buenas tardes,

Tengo dos tablas denominadas como Datos Viejos y Datos Nuevos. Cada tabla tiene como 40 columnas, cada columna tiene un valor determinado que cuando se llego a hacer un UPDATE en la base de datos entonces los datos de la tabla Datos Viejos fueron modificados y se crea la tabla Datos Nuevos donde se cuenta con la modificacion de alguna de las 40 columnas.

 

La finalidad del filtro o script que estoy buscando es que pueda determinar la linea 1 de Datos Viejos vs la linea1 de Datos Nuevos y poder identificar cual de las 40 columnas fue la sufrio la modificación.

hi  @Anonymous 

You may try these two ways as below:

1. Use merge function in power query to merge two tables.

2. Create a relationship between the two tables

If not your case, please share some sample pbix file and your expected output.
