Model
type Invoice struct {
ID uint `gorm:"primarykey" json:"-"`
UID uuid.UUID `gorm:"type:UNIQUEIDENTIFIER;uniqueIndex:idx_UniqueID" json:"id"`
}
On database value dispalayed as
But When I retriving data from database I get different values from those in db
Handler
func GetInvoices(c *fiber.Ctx) error {
invoices := []responses.Invoice{}
var invoicesCount int64
page, pageSize, searchString, orderBy := handles.Pages(c)
switch orderBy {
case "customer_name":
orderBy = "CustomerName"
case "currency_id":
orderBy = "ForeignCurrenycID"
default:
orderBy = "ID"
}
if err := database.DB.Model(&models.Invoice{}).Select("ID").Where("InvNumber like ? or CustomerName like ? or Tax_Number like ? or Registration like ? or Description like ?", searchString, searchString, searchString, searchString, searchString).Count(&invoicesCount).Error; err != nil {
logs.ErrorLogger.Println(err.Error())
return c.Status(400).JSON(fiber.Map{"msg": err.Error()})

Your uuid package should support mssql, and has nothing to do with gorm.
Comment From: wang-xuemin
建议使用：mssql.UniqueIdentifier
type TestDemo struct {
Id int `json:"id" gorm:"autoIncrement;column:Id"`
Age int `json:"age" gorm:"index;column:Age"`
Mobile string `json:"mobile" gorm:"column:Mobile"`
Email string `json:"email" gorm:"column:Email"`
CreateTime time.Time `json:"create_time" gorm:"column:createTime"`
UserId mssql.UniqueIdentifier `json:"user_id" gorm:"column:UserId;type:guid;"`
}

`import ( "database/sql/driver" mssql "github.com/microsoft/go-mssqldb" )
type Guid struct { guid mssql.UniqueIdentifier }
func (j *Guid) Scan(value interface{}) error { return j.guid.Scan(value) }
func (j Guid) Value() (driver.Value, error) { return j.guid.Value() }
func (j Guid) String() string { return j.guid.String() }
func (j Guid) MarshalText() ([]byte, error) { return []byte(j.guid.String()), nil }` This works for me. Substitute uuid.UUID with this Guid struct.
