API
constructor(name, version?)
name: 数据库名字
version: 数据库版本 默认1
eg: var driver = new Driver('database')
open
打开数据库连接 返回promise对象 在resolve中可以创建表或者删除表
driver.open().then(() => {
driver.createTable({
name: 'table',
primaryKey: 'key',
indexes: [
{name: 'name_index', column: 'key', unique: true},
],
})
})
Driver.prototype.insert(table, data)
table: 表名
data: 需要插入的数据 obj or array
eg: driver.insert({key: 'key', name: '', ...})
Driver.prototype.select(table, keyRange?, limit?)
table: 表名
keyRange: KeyRange 包含多种比较操作
limit: 取出记录数
eg: driver.select('table', keyRange.eq('key'), 1).then(rs => console.log(rs))
Driver.prototype.selectByKey(table, key)
table:表名
key: 主键
eg: driver.selectByKey('key').then(rs => console.log(rs))
Driver.prototype. count (table, keyRange?)
根据条件统计记录数
table: 表名
keyRange: @see select
eg: driver.count('table').then(size => console.log(size))
Driver.prototype. update (table, modify, where?)
数据更新,如果数据不存在则新增
table: 表名
modify: 修改的对象
where:条件
eg: driver.update('table', {name: 'xxxx'}, {key: 'key'})
Driver.prototype.delete (table, key)
table: 表名
key: 主键
根据主键删除
eg: driver.delete('table', 'key')
Driver.prototype.truncate(table)
清空某张表
table:表名
示例
const driver = new Driver('pallet', 1);
driver.on("process", function (state) {
console.log(state)
})
driver.open().then(function () {
var arrPlayers = []
for(let i=0; i<100; i++) {
arrPlayers.push({
name: `韩梅梅${i}`,
sex: `女${i}`
})
}
driver.createTable({
name: 'player',
primaryKey: 'id',
autoIncrement: true,
indexes: [
{name: 'name_index', column: 'name', unique: true},
],
data : arrPlayers
})
})
