Example of use

Task

Connect to MsSqlServer database and execute the query

SELECT * FROM Table1
ORDER BY id ASC;

Solution

Use the actions "Connect Standard Db", "Execute Sql Statement".

Implementation

Assemble a robot scheme consisting of actions:
Configure the settings for the "Connect Standard Db" action.

In the "DATABASE TYPE" field, select the appropriate database to which you want to connect.
Specify the database Login and Password.
The Server host can be specified either by IP of the host where the database is installed or by host name.
Specify the Server port, as well as the DB name.
In the "Timeout" field, the value is calculated in seconds.
In the "Parameters" field specify additional parameters for connection, usually these are parameters that relate to security. Parameters are specified in the form of a dictionary.

Learn more about the "Transaction isolation level" parameter. Sequential database operations can be divided into transactions. A transaction is a group of operations that represent a certain boolean unit of work with the database. For example, it is necessary to perform several operations with a table in order to update the data in it. If an error occurs, you can roll back the transaction, i.e. a group of operations made, so that you don't have to figure out at which step this error occurred.

If the checkbox "Transaction isolation level" is activated, part of the executed queries to the database will be in the form of transactions.
