Gorm 原始 SQL pq：运算符不存在：文本 > 整数

如何解决Gorm 原始 SQL pq：运算符不存在：文本 > 整数

我使用 Gorm 进行了原始 sql 查询，如下所示：

updateValues[fmt.Sprintf("code%d",0)] = prices[0].Code
updateValues[fmt.Sprintf("bid%d",0)] = prices[0].BidPrice
updateValues[fmt.Sprintf("last%d",0)] = prices[0].LastTradedPrice
updateValues2 = append(updateValues2,fmt.Sprintf("(@code%d,@last%d,@bid%d)",0))

query := "UPDATE myTable as e set"
query += " last = case when c.last > 0 THEN c.last else e.last end,"
query += " bid = case when c.bid > 0 THEN c.bid else e.bid end"
query += " from (values" + strings.Join(updateValues2,",")
query += ") as c(code,last,bid) where c.code = e.code"

err = r.db.Exec(query,updateValues).Error

日志显示此错误：

2021/03/13 21:08:05 repo.go:102 pq: operator does not exist: text > integer
[0.236ms] [rows:0] UPDATE myTable as e set last = case when c.last > 0 THEN c.last else e.last end,bid = case when c.bid > 0 THEN c.bid else e.bid end from (values('XXXX',169.000000,0.000000)) as c(code,bid) where c.code = e.code

当 169.000000 和 0.000000 周围没有单引号时，为什么它说 text > integer？我也在数据库控制台上运行查询并且它有效
