API 文档暂时还没有,下面是使用的 demo
pg-helper
use node-postgres easier
Examples
const {PgHelper} = require('@c_kai/pg-helper'); // detail https://node-postgres.com/api/pool const pgHelper = new PgHelper({ host, user, password, database, port: 5432, max: 20, idleTimeoutMillis: 30000, connectionTimeoutMillis: 2000, }); insert
const result = await pgHelper.insert([{ percentage: 0, type: 'public', params: {}, created_by: 1, status: 'created', job_uuid: '103', },{ percentage: 0, type: 'public', params: {}, created_by: 1, status: 'created', job_uuid: '104', }], { tableName: 'jobs', returning: true, }); delete
const result = await pgHelper.delete({}, { tableName: 'jobs', transaction, }); update
const result = await pgHelper.update({ type: 'pravate', status: 'gg', }, { update: ['type', 'status'], tableName: 'jobs', returning: ['id'], transaction, }); select
const result = await pgHelper.select({ percentage: 0, }, { where: { percentage: '= {percentage}' or: { id: '=1', } }, schemaName: 'public', tableName: 'jobs', autoHump: false, count: true, }); Run sql
await pgHelper.runSql('select now()'); // with params await pgHelper.runSql('select power({a}, {b})', { a: 2, b: 4 }); Run sql use transaction
await pgHelper.runTSql([ { sql: 'select now()', }, { sql: 'select power({a}, {b})', params: { a: 2, b: 4} } ]) OR
let transaction; try { transaction = await pgHelper.getTransaction(); let result4 = await pgHelper.runSql('select {str1} || {str2}', { str1: 'xiao', str2: 'hong', }, { transaction, }); transaction.commit(); console.log(result4) } catch (error) { transaction.rollback(); }
