golang-mysql-bridge

Go 实现MySQL桥，支持单/多条SQL语句执行，支持有序/无序数据查询，支持单条带参数SQL执行。超方便~~~

使用

导入mysql_bridge/utils包即可

主要方法

• func ExecSqlBySqlMap(sqlObject map[string]string) (map[string]interface{})
• func ExecSqlBySqlSlice(sqlObject []string) ([]interface{})
• func ExecSql(sql string, args ...interface{}) (rowsAffected int64, lastInsertId int64, err error)

实例

package main

    execSqlSlice()

    sqlResult := utils.ExecSqlBySqlMap(sqls)

    jsonResult, _ := json.Marshal(sqlResult)
