mysql - 使用 objection.js 将数组数据批量插入到 mysql 数据库中

Question

我有一个数组

newData = [{ sId: 'XXXXXX', itemlName: 'LSｽﾄﾚｯ', iCode: 'XXXXXX', iType: '', skus: 'XXXXXXX', iLevel: 'L2', cCode: '88', cName: 'Other', sCode: '999', sName: 'No Control', pLengthCode: '988', core: 'N', sCode: '1', dCode: 'XX', gDeptCode: 'XX', gDeptName: 'Women\\\'s Items', rCode: 'jqs' },{ sId: 'XXXXXX', itemlName: 'LSｽﾄﾚｯ', iCode: 'XXXXXX', iType: '', skus: 'XXXXXXX', iLevel: 'L2', cCode: '88', cName: 'Other', sCode: '999', sName: 'No Control', pLengthCode: '988', core: 'N', sCode: '1', dCode: 'XX', gDeptCode: 'XX', gDeptName: 'Women\\\'s Items', rCode: 'jqs' }]

我想使用 objection.js 将 newData 插入到 mysql 数据库中。但是当我运行我的 Node 应用程序时，我收到错误消息:

Error: batch insert only works with Postgresql

我的插入代码是-:

samplemodel.query().insert( newData );

如何使用objection.js批量插入mysql数据库中的数组数据？

Answer 1

错误:批量插入只适用于 Postgresql

好吧，这意味着您需要 Postgres 而不是 Mysql 才能使其工作。

编辑1:

来自文档:

If you are using Postgres the inserts are done in batches for maximum performance. On other databases the rows need to be inserted one at a time. This is because postgresql is the only database engine that returns the identifiers of all inserted rows and not just the first or the last one.

这意味着如果你正在使用 mysql 你应该这样做

samplemodel.query().insert(data);

对于“newData”数组中的每个元素。
