1.?Scan的??是指?的?候,也就是*Result,?有??到?据,返回sql.ErrNoRows

var

 Result

q

 g
.
DB
(
"default"
).
Model
(
"results"
).
Where
(
"1!=1"
)
err

 q
.
Scan
(
&

fmt
.
Println
(
"err="
, 
err
)
  1. ?Scan的??是二?指?的?候,也就是**Result,?有??到?据,?有返回sql.ErrNoRows
var
 results
 *
Result

q
 :=
 g
.
DB
(
"default"
).
Model
(
"results"
).
Where
(
"1!=1"
)
err

 q
.
Scan
(
&
results
)
fmt

3.?Scan的??是*[]Result或者*[]*Result的?候,?有??到?据,?有返回sql.ErrNoRows

var
 results
 []
*
Result

q
 :=
 g
.
DB
(
"default"
).
Model
(
"results"
).
Where
(
"1!=1"
)
err
 :=
 q
.
Scan
(
&
results
)
fmt
.
Println
(
"err="
, 
err

建??一返回??,或者不返回??比?好点

What did you see happen?

err= sql: no rows in result set
err= nil
err= nil

What did you expect to see?

err= nil
err= nil
err= nil

或者
err= sql: no rows in result set
err= sql: no rows in result set
err= sql: no rows in result set
