Question

Func MakeUpdateQuery(table string, set map[string]interface{}, where map[string]interface{}) (string, []interface{}) {

keys := make([]string, 0, len(set))
vals := make([]interface{}, 0, len(set))
wkeys := make([]string, 0, len(where))
for key, val := range set {
keys = append(keys, key+"=?")
vals = append(vals, val)
}

for key, val := range where {
wkeys = append(wkeys, key+"=?")
vals = append(vals, val)
}

return fmt.Sprintf(
"UPDATE %s SET %s WHERE %s",
table,
strings.Join(keys, ", "),
strings.Join(wkeys, ", "),
), vals
}
