PostgreSQL: trigger to call function with parameters

Tag: postgresql

In PostgreSQL, I'm trying to create a trigger that passes an argument to a function, but it appears that this operation looks for a function whose signature has zero arguments:

ERROR:  function create_rec_if_needed() does not exist: 
      CREATE TRIGGER after_update_winks AFTER UPDATE ON winks
      FOR EACH ROW
      WHEN (NEW.counter > 3)
      EXECUTE PROCEDURE create_rec_if_needed(NEW.id, 'Wink')

When I list extant functions, I can see my 2-argument function. Here's the output of \df:

                                                          List of functions
 Schema |          Name           |     Result data type      |                          Argument data types    
--------+-------------------------+---------------------------+-------------------------------------------------
 public | create_rec_if_needed    | void                      | rec_id integer, rec_type text

Can anyone shed a bit of light on why my trigger isn't making use of the existing function? Is there an alternative design I should use to reach my goal? My aim is for multiple tables to have a trigger that calls the function create_rec_if_needed, and in each case, the trigger must supply the id of the record and a table-specific string.

Best How To :

A trigger procedure is created with the CREATE FUNCTION command, declaring it as a function with no arguments and a return type of trigger.

You can use the arguments passed to the trigger function via TG_ARGV, e.g. TG_TABLE_NAME - the name of the table that caused the trigger invocation. 40.9. Trigger Procedures.

For string literals, you should you single quote instead of double quote: UPDATE rv_template_fields SET view = 'display_type_1' WHERE rv_template_fields.view = 'display_type_2' Double quotes are for quoting identifiers of fields and relations, like, for instance view, so that you could write also: UPDATE rv_template_fields SET "view" = 'display_type_1' WHERE "view"...

So the problem was that em.createNativeQuery(...) was not the correct invocation of a NamedNativeQuery in order to do that I should've invoked em.createNamedQuery(...).

How to group following rows by not unique value

If your case is as simple as the example values suggest, @Giorgos' answer serves nicely. However, that's typically not the case. If the id column is a serial, you cannot rely on the assumption that a row with an earlier time also has a smaller id. Also, time values (or...

Speed up Min/Max operation on postgres with index for IN operator query

It turned out (please see comments), that this query: SELECT MIN(minimal) AS minimal FROM ( SELECT MIN("products"."shipping") AS minimal FROM "products" WHERE "products"."tag_id" IN (?,?,?,?,?,?,?)
