如何使用gorm从数据库中删除项目范围

Question

每次我运行 gorm 查询以从表中删除一系列行时，我都会收到以下错误。(/home/gregf/code/go/src/github.com/gregf/gormtest/main.go:39)[2015-06-24 18:55:56]  [0.34ms]  SELECT  id FROM "podcasts"(/home/gregf/code/go/src/github.com/gregf/gormtest/main.go:50)[2015-06-24 18:55:56]  near "LIMIT": syntax error(/home/gregf/code/go/src/github.com/gregf/gormtest/main.go:50)[2015-06-24 18:55:56]  [0.82ms]  DELETE FROM "episodes"  WHERE (podcast_id = '1') LIMIT 4 OFFSET 22015/06/24 18:55:56 &{{0 0   false } near "LIMIT": syntax error 0 <nil> 0xc20802c280 0xc20802c140 0xc20802f900 2 <nil> <nil> false  map[gorm:started_transaction0xc2080380c00xc20805a1c0:true] map[]}在sqlite3中直接运行查询返回就好了DELETE FROM "episodes"  WHERE (podcast_id = '1') LIMIT 4 OFFSET 2;Run Time: real 0.000 user 0.000000 sys 0.000000示例代码package mainimport (    "log"    "github.com/jinzhu/gorm"    _ "github.com/mattn/go-sqlite3")type Podcast struct {    Id       int    Title    string    RssUrl   string `sql:"unique_index"`    Episodes []Episode}type Episode struct {    Id         int    PodcastID  int    Title      string    Url        string `sql:"unique_index"`    Downloaded bool    Guid       string `sql:"unique_index"`}func main() {    db, err := gorm.Open("sqlite3", "cache.db")    if err != nil {        log.Fatal(err)    }    db.LogMode(true)    db.CreateTable(&Podcast{})    db.CreateTable(&Episode{})    rows, err := db.Table("podcasts").Select("id").Rows()    if err != nil {        log.Fatal(err)    }    for rows.Next() {        var podcastId int        rows.Scan(&podcastId)        err := db.Table("episodes").Where("podcast_id = ?", podcastId).            Limit(4).            Offset(2).            Delete(Episode{})        if err != nil {            log.Printf("%s\n", err)        }    }}
