Description
type Data struct{
ID int64
IntCol int64
}
createSql:=`CREATE TABLE IF NOT EXISTS %s (
id SERIAL PRIMARY KEY,
int_col INT);`
pgsql := g.DB("pgsql")
tableName := "Type_Table_" + gtime.Now().TimestampMilliStr()
// pgsql will convert the table name to lowercase
pgsql.Exec(ctx, fmt.Sprintf(createSql, tableName))
//Insert data
//Write any data
var data = Data {
Id:1,
IntCol:2,
}
// The tableName here is the same variable as above.
_, err := pgsql.Model(tableName).Data(data).Insert()
fmt.Println(err)
//output:
// INSERT INTO "Type_Table_1714453562918"("") VALUES() : pq: delimiter identifier of length 0 at or near """"
// The error given is confusing
// When the table name is the same as the one that just created the table, after randomly inserting a piece of data into the table
// update data,
_, err = pgsql.Model(tableName).Where("id", 1).Data(g.Map{
"int_col": 9999,
}).Update()
fmt.Printf("%+v\n", err)
//output:
// data cannot be empty
// The error given is also confusing
After debugging, I found that (c *Core) mappingAndFilterData
This method will get all the fields of the table, and then compare it with the field name of the structure to be inserted, and delete the ones that do not exist, but because the table I passed in during the Insert operation The name is not all lowercase, so the field cannot be found and no error is returned. As a result, when inserting later, there is no data and an error is reported.
