Provides methods that notify about result lines of the executed query. See [https://docs.influxdata.com/influxdb/latest/api/#operation/PostQuery](https://docs.influxdata.com/influxdb/latest/api/#operation/PostQuery) ## Methods ### collectLines() > **collectLines**(`query`): `Promise`\<`string`\[]> Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1148 CollectLines executes the query and collects all result lines in the returned Promise. This method is suitable to collect simple results. Use with caution, a possibly huge stream of lines is copied to memory. #### Parameters ##### query `string` | `ParameterizedQuery` query #### Returns `Promise`\<`string`\[]> Promise of returned csv lines *** ### collectRows() > **collectRows**\<`T`>(`query`, `rowMapper?`): `Promise`\<`T`\[]> Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1139 CollectRows executes the query and collects all the results in the returned Promise. This method is suitable to collect simple results. Use with caution, a possibly huge stream of results is copied to memory. #### Type Parameters ##### T `T` #### Parameters ##### query `string` | `ParameterizedQuery` query ##### rowMapper? (`values`, `tableMeta`) => `T` | `undefined` maps the supplied row to an item that is then collected, undefined return values are not collected. If no rowMapper is supplied, `row => tableMeta.toObject(row.values)` is used. #### Returns `Promise`\<`T`\[]> Promise of mapped results *** ### iterateLines() > **iterateLines**(`query`): `AsyncIterable`\<`string`> Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1081 IterateLines executes the supplied query and returns results in an async iterable of annotated CSV lines. Async iterables are best consumed by `for-await` loop. #### Parameters ##### query `string` | `ParameterizedQuery` query #### Returns `AsyncIterable`\<`string`> async iterable of CSV result lines *** ### iterateRows() > **iterateRows**(`query`): `AsyncIterable`\<`Row`> Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1090 IterateRows executes the supplied query and returns results in an async iterable of row data and table metadata pairs. Async iterables are best consumed by `for-await` loop. #### Parameters ##### query `string` | `ParameterizedQuery` query #### Returns `AsyncIterable`\<`Row`> async iterable of CSV result lines *** ### lines() > **lines**(`query`): `Observable`\<`string`> Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1097 Creates a cold observable of the lines returned by the given query. #### Parameters ##### query `string` | `ParameterizedQuery` query #### Returns `Observable`\<`string`> observable of CSV result lines *** ### queryLines() > **queryLines**(`query`, `consumer`): `void` Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1112 Executes the query and receives result lines (including empty and annotation lines) through the supplied consumer. See [annotated-csv](https://docs.influxdata.com/influxdb/latest/reference/syntax/annotated-csv/). #### Parameters ##### query `string` | `ParameterizedQuery` query ##### consumer `CommunicationObserver`\<`string`> csv result lines and error consumer #### Returns `void` *** ### queryRaw() > **queryRaw**(`query`): `Promise`\<`string`> Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1127 QueryRaw executes a query and returns the full response as a string. Use with caution, a possibly huge stream is copied to memory. #### Parameters ##### query `string` | `ParameterizedQuery` query #### Returns `Promise`\<`string`> Promise of response text *** ### queryRows() > **queryRows**(`query`, `consumer`): `void` Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1119 Executes the query and receives table metadata and rows through the supplied consumer. #### Parameters ##### query `string` | `ParameterizedQuery` query ##### consumer `FluxResultObserver`\<`string`\[]> result rows and error consumer #### Returns `void` *** ### response() > **response**(`query`): `AnnotatedCSVResponse` Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1072 Response returns an AnnotatedCSVResponse instance that executes the query when asked for data. #### Parameters ##### query `string` | `ParameterizedQuery` query #### Returns `AnnotatedCSVResponse` response with various methods to process data from the returned annotated CSV response data stream *** ### rows() > **rows**(`query`): `Observable`\<`Row`> Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1104 Creates a cold observable of the rows returned by the given query. #### Parameters ##### query `string` | `ParameterizedQuery` query #### Returns `Observable`\<`Row`> observable of result rows *** ### with() > **with**(`options`): `QueryApi` Defined in: node\_modules/.pnpm/@influxdata+influxdb-client\@1.35.0/node\_modules/@influxdata/influxdb-client/dist/index.d.ts:1063 Returns a new query API with extra options applied. #### Parameters ##### options `Partial`\<`QueryOptions`> query options to use #### Returns `QueryApi` queryApi instance with the supplied options
