The data record result (Value) of gdb supports very flexible type conversion and has built-in support for dozens of common data types.

The Value type is an alias for the *gvar.Var type, so you can use all the conversion methods of the gvar.Var data type. For details, please refer to the Generic section.

Example usage:

First, the data table is defined as follows:

# Product Table
CREATE TABLE `goods` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`title` varchar(300) NOT NULL COMMENT 'Product Name',
`price` decimal(10,2) NOT NULL COMMENT 'Product Price',
...
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

Next, the data in the table is as follows:

id   title     price
1 IPhoneX 5999.99

Finally, the sample code is as follows:

if r, err := g.Model("goods").FindOne(1); err == nil {
fmt.Printf("goods id: %d\n", r["id"].Int())
fmt.Printf("goods title: %s\n", r["title"].String())
fmt.Printf("goods proce: %.2f\n", r["price"].Float32())
} else {
g.Log().Error(gctx.New(), err)
}

After execution, the output is:

goods    id: 1
goods title: IPhoneX
goods proce: 5999.99
