Idiomatic approach to UpdateIfExists conditions using sqlc

[kumarankitapp]

DB: Mysql
Version: 8.0.31

Use case:

- INSERT INTO table t1 if record doesn't exist
- UPDATE record in table t1 if record exists

What I am trying to do is use INSERT INTO ON DUPLICATE KEY as below
INSERT INTO t1 (a,b,c) VALUES (1,2,3) ON DUPLICATE KEY UPDATE b=22,c=33;

When I run sqlc generate on my query, the params struct, and the corresponding method creates a duplicate value field with _2 naming convention. Eg:

_Query:_

-- name: CreateX :exec
INSERT INTO t1 (
   a,
   b,
   c
) VALUES (
             ?,?,?
         ) ON DUPLICATE KEY UPDATE
    b  = ?,
    c  = ?,
    
;

_generated code snippet:_

type CreateXParams struct {
a string
b string 
c string 
b_2 string   <-- 
c_2 string   <-- 
}

func (q *Queries) CreateX(ctx context.Context, arg CreateXParams) error {
	_, err := q.db.ExecContext(ctx, createx,
		arg.a,
		arg.b,
		arg.c,
                 arg.b_2,  <--
		arg.c_2,  <--
        )
return err
}

Is there a right way to create a query as such or should break these into 2 separate queries ( INSERT INTO >> check for duplicate key error >> if err then as a response UPDATE)

I cannot use INSERT IGNORE or REPLACE INTO for my use case.
New to sqlc, so any suggestions are appreciated!!
