You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: sqlcipher.go
    path of file: ./repos/migrate/database/sqlcipher
    
    the code of the file until where you have to start completion: package sqlcipher

import (
	"database/sql"
	"fmt"
	"io"
	nurl "net/url"
	"strconv"
	"strings"

)

func init() {
	database.Register("sqlcipher", &Sqlite{})
}

var DefaultMigrationsTable = "schema_migra
    
func WithInstance(instance *sql.DB, config *Config) (database.Driver, error) {
	if config == nil {
		return nil, ErrNilConfig
	}

	if err := instance.Ping(); err != nil {
		return nil, err
	}

	if len(config.MigrationsTable) == 0 {
		config.MigrationsTable = DefaultMigrationsTable
	}

	mx := &Sqlite{
		db:     instance,
		config: config,
	}
	if err := mx.ensureVersionTable(); err != nil {
		return nil, err
	}
	return mx, nil
