Use from the command line:

$ sql2pb -h
Usage of sql2pb:
 -db string
 the database type (default "mysql")
 -field_style string
 gen protobuf field style, sql_pb | sqlPb (default "sqlPb")
 -go_package string
 the protocol buffer go_package. defaults to the database schema.
 -host string
 the database host (default "localhost")
 -ignore_columns string
 a comma spaced list of mysql columns to ignore
 -ignore_tables string
 a comma spaced list of tables to ignore
 -package string
 the protocol buffer package. defaults to the database schema.
 -password string
 the database password (default "root")
 -port int
 the database port (default 3306)
 -schema string
 the database schema
 -service_name string
 the protobuf service name , defaults to the database schema.
 -table string
 the table schema,multiple tables ',' split. (default "*")
 -user string
 the database user (default "root")

$ sql2pb -go_package ./pb -host localhost -package pb -password root -port 3306 -schema usercenter -service_name usersrv -user root > usersrv.proto

Use as an imported library

$ go get -u github.com/Mikaelemmmm/sql2pb@latest

package main
import (
	"database/sql"
	"fmt"
	"github.com/Mikaelemmmm/sql2pb/core"
	_ "github.com/go-sql-driver/mysql"
	"log"
)
func main() {
	dbType:= "mysql"
	connStr := fmt.Sprintf("%s:%s@tcp(%s:%d)/%s", "root", "root", "127.0.0.1", 3306, "zero-demo")
	pkg := "my_package"
	goPkg := "./my_package"
	table:= "*"
	serviceName:="usersrv"
	fieldStyle := "sqlPb"
	db, err := sql.Open(dbType, connStr)
	if err != nil {
		log.Fatal(err)
	}
	defer db.Close()
	s, err := core.GenerateSchema(db, table,nil,nil,serviceName, goPkg, pkg,fieldStyle)
	if nil != err {
		log.Fatal(err)
	}
	if nil != s {
		fmt.Println(s)
	}
}
