Calling Stored Procedure in GoLang with QueryRowContent - mysql

Question

Im trying to run the below code segment and keeps throwing the below error from QueryRowContext
sql: expected 0 arguments, got 2
This approach works with plain SQL queries and I keep getting the issue when I try to call a Stored Prod to the query param with the CALL keyword.
import (
"database/sql"
"net/http"
)
func VerifyUser(user User) (*User, string, error) {
db, ctx := db.GetDB()
query := "CALL usp_GetUserByUsername(#Email)"
stmt, err := db.Prepare(query)
if err != nil {
log.Errorln("Error in preparing statement. " + err.Error())
return nil, "Error in preparing statement.", err
}
defer stmt.Close()
row := stmt.QueryRowContext(ctx, sql.Named("Email", user.Email))
var retUser User
err = row.Scan(&retUser.ID, &retUser.Email, &retUser.Password, &retUser.Status)
if err != nil {
log.Warningln("Unknown Email: " + user.Email + ". " + err.Error())
return nil, "Invalid user.", err
}
What seems to be wrong here? Thanks in advance.

import (
"database/sql"
"net/http"
)
func VerifyUser(user User) (*User, string, error) {
db, ctx := db.GetDB()
query := "CALL usp_GetUserByUsername(?)"
stmt, err := db.Prepare(query)
if err != nil {
log.Errorln("Error in preparing statement. " + err.Error())
return nil, "Error in preparing statement.", err
}
defer stmt.Close()
row := stmt.QueryRowContext(ctx, user.Email)
var retUser User
err = row.Scan(&retUser.ID, &retUser.Email, &retUser.Password, &retUser.Status)
if err != nil {
log.Warningln("Unknown Email: " + user.Email + ". " + err.Error())
return nil, "Invalid user.", err
}
Replace #Email in your query with ? and pass the email into QueryRowContext not named statement
