How to pass a parameter in a query to postgreSQL 12

[Hassan Camacho Cadre <hccadre@xxxxxxxxx>]

Hello

I recently installed a postgreSQL v12, in previous version 8.3 in all my queries I pass parameters using the character :

SELECT

  public.tabla.id

FROM 

  public.tabla

WHERE  

  public.tabla.id = :a

In the new version when I try to make this query it sends me an error

ERROR syntax error at or near ":"

 

I tried

 

?a , ¿a, @a

 

But I always got an error

I am executing this query on the query editor of pgadmin 4

Could someone help me to know how I can configure the parameter passing character or, failing that, how I should pass the parameters in this new version.

Greetings
