# ConvertAmount: Open Exchange Rates Convert Amount ## Documentation Convert any money value from one currency to another at the latest API rates using the /convert API endpoint. This feature works differently to other endpoints in our API, using a REST-based approach and an alternate response format. Currency conversion requests are currently available for clients on the Unlimited plan. - Catalog: `OpenExchangeRates` - Schema: `OpenExchangeRates` - Label: Convert Amount This is a read-only table function. The Open Exchange Rates API may not support changing the data or the Invantive UniversalSQL driver for Open Exchange Rates does not cover it. In the latter case, please use the table NativePlatformScalarRequests to upload data to the Open Exchange Rates API. ## Parameters of Table Function The following parameters can be used to control the behaviour of the table function `ConvertAmount`. A value must be provided at all times for required parameters, but optional parameters in general do not need to have a value and the execution will default to a pre-defined behaviour. Values can be specified by position and by name. In both cases, all parameters not specified will be evaluated using their default values. Value specification by position is done by listing all values from the first to the last needed value. For example: a `select * from table(value1, value2, value3)` on a table with four parameters will use the default value for the fourth parameter and the specified values for the first three. Value specification by name is done by listing all values that require a value. For example with `select * from table(name1 => value1, name3 => value3)` on the same table will use the default values for the second and fourth parameters and the specified values for the first and third. | Name | Data Type | Required | Default Value | Documentation | |---|:---:|:---:|:---:|---| | `from` | `` | ☑ | | The base ('from') currency (3-letter code). | | `to` | `` | ☑ | | The target ('to') currency (3-letter code). | | `value` | `` | ☑ | | The value to be converted. | ## Columns of Table Function The columns of the table function `ConvertAmount` are shown below.
