Golang Postgres Scan To Struct - fucktimkuik.org

Golang Postgres "LastInsertId is not supported by this driver" Golang 使用反射获取 struct 的值; Golang 使用反射获取 interface 中属性的值并转化为 map[string]interface. PostgreSQL is an object-relational database management system available for many platforms including Linux, FreeBSD, Solaris, Microsoft Windows and Mac OS X. It is released under an MIT-style license, and is thus free and open source software. It's larger than MySQL because it's designed for enterprise usage as an alternative to Oracle. Postgresql is a good choice for enterprise type projects.

Handling JSONB in Go Structs February 16, 2016 In a previous post I already described how much database design can be simplified by using the PostgreSQL JSONB datatypes for storing entity properties. Here, I’ll show how you can map this design directly onto your structs in Go. We want to handle this kind of entity in our application. dgw generates Golang struct, and simple Table/Row Data Gateway functions from PostgreSQL table metadata. Heavily inspired by xo. Why created. Personally, I prefer Table/Row Data Gateway over. 一、PostgreSQL介绍. PostgreSQL is a powerful, open source object-relational database system. PostgreSQL 是一个功能强大的开源对象关系数据库管理系统 ORDBMS 。 用于安全地存储数据; 支持最佳做法,并允许在处理请求时检索它们。 特点.

Scanners and Valuers with Go. Jun 12, 2015. Data structure serialization in databases can be difficult with golang types. For example, say we want to have a custom type as an attribute in a type. How can we get this typed attribute inserted and read from a sql database. Golang offers a mechanism to allow for this: Implement Scanner and Valuer. The default behavior of structs is now to sequentially scan the struct fields. If some of the fields are unexported, the new implementation will defer to the old behavior. This change does not affect any types that already implement the Scanner interface. Testing for embedded struct added. PostgreSQL offers various functions to convert rows to JSON row_to_json, etc. I was think to use these functions to allow mapping sql.Rows to struct without using a external dependency. I've tried sqlx and various others but they all have some kind of edge case that they don't support OUTER JOINS for example. What is your opinion about.
