错误,可以按照以下步骤进行操作:
const { BigQuery } = require('@google-cloud/bigquery');
const { GoogleAuth } = require('google-auth-library');
const auth = new GoogleAuth();
const authClient = await auth.getClient();
const bigquery = new BigQuery({ projectId: 'YOUR_PROJECT_ID', auth: authClient });
const datasetId = 'YOUR_DATASET_ID';
const tableId = 'YOUR_TABLE_ID';
const dataset = bigquery.dataset(datasetId);
const table = dataset.table(tableId);
await table.delete();
const [exists] = await table.exists();
if (exists) {
await table.delete();
} else {
console.log('Table does not exist.');
}
完整的代码示例:
const { BigQuery } = require('@google-cloud/bigquery');
const { GoogleAuth } = require('google-auth-library');
async function deleteBigQueryTable() {
try {
const auth = new GoogleAuth();
const authClient = await auth.getClient();
const bigquery = new BigQuery({ projectId: 'YOUR_PROJECT_ID', auth: authClient });
const datasetId = 'YOUR_DATASET_ID';
const tableId = 'YOUR_TABLE_ID';
const dataset = bigquery.dataset(datasetId);
const table = dataset.table(tableId);
const [exists] = await table.exists();
if (exists) {
await table.delete();
console.log('Table deleted successfully.');
} else {
console.log('Table does not exist.');
}
} catch (error) {
console.error('Error deleting table:', error);
}
}
deleteBigQueryTable();
请注意,上述代码中的"YOUR_PROJECT_ID"、"YOUR_DATASET_ID"和"YOUR_TABLE_ID"需要替换为实际的项目ID、数据集ID和表ID。
