This is the implementation of the SAP SQL Anywhere data handler for MindsDB. SAP SQL Anywhere is an embedded database for application software that enables secure and reliable data management for servers where no DBA is available and synchronization for tens of thousands of mobile devices, Internet of Things (IoT) systems, and remote environments.

​
Prerequisites

Before proceeding, ensure the following prerequisites are met:
  1. Install MindsDB locally via Docker or use MindsDB Cloud.
  2. To connect SAP SQL Anywhere to MindsDB, install the required dependencies following this instruction.
  3. Install or ensure access to SAP SQL Anywhere.

​
Implementation

This handler is implemented using sqlanydb, the Python driver for SAP SQL Anywhere. The required arguments to establish a connection are as follows:
  • host is the host name or IP address of the SAP SQL Anywhere instance.
  • port is the port number of the SAP SQL Anywhere instance.
  • user specifies the user name.
  • password specifies the password for the user.
  • database sets the current database.
  • server sets the current server.

​
Usage

You can use the below SQL statements to create a table in SAP SQL Anywhere called TEST. 
CREATE TABLE TEST
(
    ID          INTEGER NOT NULL,
    NAME        NVARCHAR(1),
    DESCRIPTION NVARCHAR(1)
);

CREATE UNIQUE INDEX TEST_ID_INDEX
    ON TEST (ID);

ALTER TABLE TEST
    ADD CONSTRAINT TEST_PK
        PRIMARY KEY (ID);

INSERT INTO TEST
VALUES (1, 'h', 'w');
In order to make use of this handler and connect to the SAP SQL Anywhere database in MindsDB, the following syntax can be used: 
CREATE DATABASE sap_sqlany_trial
WITH
    ENGINE = 'sqlany', 
    PARAMETERS = {
        "user": "DBADMIN",
        "password": "password",
        "host": "localhost",
        "port": "55505",
        "server": "TestMe",
        "database": "MINDSDB"
    };
You can use this established connection to query your table as follows: 
SELECT *
FROM sap_sqlany_trial.test;
On execution, we get:
