Description
Your Question
The following SQL queries are executed:
`SELECT count(*) FROM INFORMATION_SCHEMA.tables WHERE table_name = $1 AND table_type = 'BASE TABLE' AND table_schema = CURRENT_SCHEMA()
terminals
SELECT count(*) FROM INFORMATION_SCHEMA.columns WHERE table_name = $1 AND column_name = $2 AND table_schema = CURRENT_SCHEMA()
terminals id
SELECT count(*) FROM INFORMATION_SCHEMA.columns WHERE table_name = $1 AND column_name = $2 AND table_schema = CURRENT_SCHEMA()
terminals version
SELECT * FROM "terminals" WHERE (deleted_at IS NULL) ORDER BY created_at DESC LIMIT 1`
The versions I am using are as follows:
github.com/lib/pq v1.10.9
gorm.io/driver/postgres v1.5.11
gorm.io/gorm v1.26.0
The structure is as follows:
type Terminal struct { ID int json:"id" gorm:"primaryKey"Version int json:"version" gorm:"default:1" comment:"协议版本号"Mac string gorm:"index" comment:"终端mac地址"MachineID string gorm:"unique;default:''" json:"machine_id" comment:"终端机器码"IP string json:"ip" comment:"终端IP"Os string json:"os" comment:"终端系统信息"ExpiredAt time.Time json:"expired_at" comment:"过期时间"CreatedAt time.Time json:"created_at" comment:"注册时间"UpdatedAt time.Time json:"updated_at" comment:"最后登录时间"DeletedAt gorm.DeletedAtjson:"deleted_at" gorm:"index"}
Table schema:
Table "public.terminals" Column | Type | Collation | Nullable | Default ------------+--------------------------+-----------+----------+--------------------------------------- id | integer | | not null | nextval('terminals_id_seq'::regclass) version | integer | | | 1 mac | text | | | machine_id | text | | | ip | text | | | os | text | | | expired_at | timestamp with time zone | | | created_at | timestamp with time zone | | | updated_at | timestamp with time zone | | | deleted_at | timestamp with time zone | | | Indexes: "terminals_pkey" PRIMARY KEY, btree (id) "terminals_machine_id_key" UNIQUE CONSTRAINT, btree (machine_id) "idx_terminals_deleted_at" btree (deleted_at) "idx_terminals_mac" btree (mac) "terminals_mac_key" btree (mac)
In the Go code, the following function is executed:
db.AutoMigrate(Terminal{})
Tracing leads to the function in github.com/lib/pq/conn.go:
func (cn *conn) query(query string, args []driver.Value) (_ *rows, err error) {}
The SQL query generated is SELECT * FROM "terminals" LIMIT $1, but the args array contains two parameters: 5 and 1.
Therefore, the error occurs: "got %d parameters but the statement requires %d".
Please help me find out where my problem lies
