## About implemented methods
This library has two parts: basic methods, like connecting and executing SQL queries, and a small ORM for common operations like CREATE, SELECT, INSERT, DELETE, and so on. Working through the ORM and through the query texts executed through the `ExecuteSQLQuery()` function is technically the same: the ORM simply generates the SQL query text based on the layouts, but then also calls them through this function
By default, all SELECT queries return an array of selected data, while other queries return only `true` in the `result` field on success, or `false` and error text in the `result` and `error` fields, respectively. To execute queries that require data to be returned but are not SELECT queries, the `ExecuteSQLQuery()` function has a `ForceResult` parameter
## Query parameters
The PostgreSQL connector supports the use of positional parameters. All values passed both when executing queries directly through the `ExecuteRequestSQL()` function and in ORM methods with value setting, such as `AddRecords` and `UpdateRecords`, must be a structure of the form `{'Data Type': 'Value'}`. The following data types are supported:
Binary data retrieved from the database will be represented as an object (structure) of the form `{"BYTES": "Base64 string"}` and must be manually converted from Base64
The library supports operation in TLS mode. To enable it, you need to configure TLS settings using the `GetTlsSettings` function and pass them as the corresponding parameter to the `CreateConnection` function or one of the ORM functions that support this parameter. If the TLS parameter is not provided when calling these functions, the connection will be initialized in an unsecured mode.
:::tip
TLS settings can only be applied when the connection is established — either explicitly when using the `CreateConnection` function or implicitly when passing a connection string to ORM methods. Providing TLS settings along with an already established connection (passed via the *Connection* parameter) will be ignored.
