MySQL
This section is dedicated to the PostMySQLgreSQL database library. On this page, all the steps necessary to start working are described
Please review the "About external components" section before getting started

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 MySQL 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*:
* The MySQL type list lists only a few suitable types
| Type name (key) | 1C type | Suitable MySQL types |
|---|---|---|
| BYTES | String (filepath), BinaryData | TINYBLOB, BLOB, MEDIUMBLOB, LONGBLOB |
| UINT | Number (integer, unsigned) | TINYINT UNSIGNED, SMALLINT UNSIGNED, MEDIUMINT UNSIGNED, INT UNSIGNED, BIGINT UNSIGNED |
| INT | Number (integer) | TINYINT, SMALLINT, MEDIUMINT, INT, BIGINT |
| FLOAT | Number | FLOAT |
| DOUBLE | Number | DOUBLE (REAL, DOUBLE PRECISION) |
| DATE | Date, String (RFC 3339) | DATE, DATETIME, TIMESTAMP |
| TIME | Дата, String (RFC 3339) | TIME |
| TEXT | String | CHAR, VARCHAR, TINYTEXT, TEXT, MEDIUMTEXT, LONGTEXT, SET |
TLS
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.
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. :::
Compatibility
Technically, the client implementation is a Native component in Rust. It comes in a zip archive format, and, in theory, should work on all available platforms: x86 and x64 Windows and Linux. The actual testing was done on Windows x64 and, cossentially (via OneScript), on Linux x64
