+**NOTE** **SQLite** doesn't support some records are default values when batch insert.
+See [SQLite Insert stmt](https://www.sqlite.org/lang_insert.html). For example:
+
+```go
+type Pet struct {
+	Name string `gorm:"default:cat"`
+}
+
+// In SQLite, this is not supported, so GORM will build a wrong SQL to raise error:
+// INSERT INTO `pets` (`name`) VALUES ("dog"),(DEFAULT) RETURNING `name`
+db.Create(&[]Pet{{Name: "dog"}, {}})
+```
+A viable alternative is to assign default value to fields in the hook, e.g.
+
+```go
+func (p *Pet) BeforeCreate(tx *gorm.DB) (err error) {
+	if p.Name == "" {
+		p.Name = "cat"
+	}
+}
+```
+
+You can see more info in [issues#6335](https://github.com/go-gorm/gorm/issues/6335)

 When using virtual/generated value, you might need to disable its creating/updating permission, check out [Field-Level Permission](models.html#field_permission)
