MySQL

Getting Started With MySQL

The Make MySQL modules let you execute your custom logic directly in your database server through stored procedures. Make loads the interface of input/output parameters and recordsets dynamically, so each parameter/value can be mapped individually.

Prerequisites:

  • A MySQL server connection

  • A Configured MySQL server

Creating a Connection to the MySQL Server

Connection name

Enter the name of the new MySQL connection you want to establish.

Host

Enter the address of the MySQL server.

The MySQL server must be publicly accessible from the internet. If you want to use the database hosted on your local server, you'll need to specify your public IP address, and set the port forwarding on your router. Do not enter "localhost," or "127.0.0.1" in this field, as it will not work.

Port

Enter the port number of the MySQL server.

Database

Enter the database name if needed. This is required for the Execute a Query (advanced) module.

User

Enter the MySQL server user name.

Password

Enter the password.

Allow insecure authentication

Enable this option to connect to MySQL instances that use the old authentication method (MySQL 4.0 and older). If needed, see additional information about Updating Old Authentication Protocol Passwords.

Charset

(optional)

Enter the MySQL character set for the connection, e.g., utf8. In this case, the utf8_general_ci MySQL collation is used. See all supported character sets and collations.

Self-signed certificate (optional)

Upload your certificate (P12, PFX, or PEM file) if you want to use TLS using your self-signed certificate. If you're using the client-side certificate authorization, you can enter your CA certificate here. Make does not retain or store any data (files, passwords) you provide. File and password are only used to extract a private key/certificate.

For more details about certificates and keys, please refer to the Certificates and Keys article.

Client Private Key (optional)

Upload the private key to use the client-side certificate authorization. Make does not retain or store any data (files, passwords) you provide. File and password are only used to extract a private key/certificate.

For more details about certificates and keys, please refer to the Certificates and Keys article.

Client Certificate (optional)

Upload your certificate if you want to use client-side certificate authorization. Make does not retain or store any data (files, passwords) you provide. File and password are only used to extract a private key/certificate.

For more details about certificates and keys, please refer to the Certificates and Keys article.

Configuring Your MySQL Server

Caution

Remote access must be allowed, and CREATE ROUTINE privilege must be granted on the MySQL server!

Read Access to MySQL Tables

Before you start configuring your scenario, make sure the account you're using to connect to your database has read access to information_schema.tables, information_schema.columns, information_schema.routines, and information_schema.parameters tables.

Make IP Addresses

Make will make connections to your database from the following IP addresses: List of IP addresses

Our servers are set up with valid PTR records, so you can easily restrict access by allowing %.make.com.

Enabling Access on Your Firewall

Enable incoming TCP connections to port 3306 from source IP addresses.

Configuring MySQL for Remote Access

Linux

1. Open the configuration file /etc/mysql/my.cnf

2. Comment outline bind-address = 127.0.0.1 (by adding a hash at the beginning of the line):

               #bind-address = 127.0.0.1
            

3. Restart the MySQL daemon

Creating and Granting Remote Access to Your MySQL Account

1. Start the MySQL command line interface:

               mysql -u root -p
            

2. Execute these commands (with <database>, <user> and <password> replaced by actual values):

               CREATE USER <user>@'%' IDENTIFIED BY <password>;
GRANT ALL PRIVILEGES ON <database>.* TO <user>@'%' IDENTIFIED BY <password> WITH GRANT OPTION;
FLUSH PRIVILEGES;
            

Tolerance of Non-interactive Connection

Make processes scenarios transactionally. That's why all Make modules that support transactions (e.g., MySQL) have open transactions throughout the whole run of a scenario. Therefore, make sure that you have set a long enough time to tolerate non-interactive connections. This MySQL command will list the values:

               SHOW VARIABLES LIKE 'wait_timeout';
            

See more information in the MySQL documentation on Server System Variables.

Actions

Insert Row Into a Table

Inserts a row with the desired values into a selected table.

Connection

Establish a connection to the MySQL server.

Table

Select the table where you want to add a row.

column name(s)

Enter the desired values that will be inserted into the new row.

Update Row(s) in a Table

Updates rows (can be defined by the filter settings) in the selected table.

Connection

Establish a connection to the MySQL server.

Table

Select the table where you want to update a row.

column name(s)

Enter the desired values that will be inserted into the rows.

Filter

Set the filter to define which rows will be updated.

Delete Row(s) From a Table

Deletes a row according to a defined filter.

Connection

Establish a connection to the MySQL server.

Table

Select the table where you want to delete the row.

Filter

Set the filter for the row to be deleted.

Set filter values. You can also use logical operators, AND/OR, to specify your selection.

Execute a Query (Advanced)

Connection

Establish a connection to the MySQL server.

Query

Enter the desired MySQL query. Make sure that the Database field under Connection settings is filled.

Variables used in the query are not sanitized. Make sure you sanitize variables properly to prevent SQL injection.

Continue the execution of the route even if the module returns no results

If enabled, the scenario will not be stopped by this module.

Only one SQL statement is allowed (one semicolon ; as a statement terminator per query).

Execute a Stored Procedure

Connection

Establish a connection to the MySQL server.

Stored procedure

Select the stored procedure you want to execute. The stored procedure must already be created.

Here is a sample SQL statement that creates a stored procedure that simply inserts the values passed in the three parameters into a table:

DELIMITER ;; CREATE PROCEDURE `insert_record_from_integromat`(IN _name text, IN _email text, IN _phone text)

BEGIN INSERT INTO contacts (name, email, phone) VALUES (_name, _email, _phone); END;;

Fields

Contains the parameter fields from the stored procedure. E.g., enter values you want to insert into the table during the stored procedure execution.

Example

The following example adds 2 to the provided parameter (e.g., in the Execute a Stored Procedure module), and returns the result, together with the current date (can be further iterated using the Iterate Recordset of a Stored Procedure module).

CREATE PROCEDURE `test_procedure`(IN id integer, OUT outid integer)
BEGIN
 set outid = id + 2;
 select id as inid, now() as current_date;
END$$

Searches

Select Row(s) From a Table

This action selects a row from a table according to a defined filter.

Connection

Establish a connection to the MySQL server.

Table

Select the table you want to select a row from.

Filter

Set the filter for the row to be selected.

Set filter values. You can also use logical operators, AND/OR, to specify your selection.

Example:

On the following MySQL dialog, the row that contains number 1 or 2 in the "column1" column will be selected.

Continue the execution of the route even if the module returns no results

If enabled, the scenario will not be stopped by this module.

Note

You may also use the existing basic text operators for comparing dates and datetimes. Just use text formatted date/datetime as the second operand:

  • YYYY-MM-DD for date type

  • YYYY-MM-DD HH:mm:ss for datetime type

Literal static datetime value example:

Troubleshooting

Error: ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client:

MySQL 8 uses an authentication method that is not supported by Make yet.

Solution

Use the mysql_native_password plugin to make the account fall back to the "traditional" process during the handshake, keeping compatibility by default for any previously supported server version.

Create the account using the mysql_native_password authentication plugin:

CREATE USER 'new_user'@'%' IDENTIFIED WITH mysql_native_password BY 'user_password';

Or, modify the existing user account, and specify the mysql_native_password authentication plugin:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YourRootPassword';

(Reference: https://github.com/mysqljs/mysql/issues/2046#issuecomment-396039909)

Error: ER_LOCK_WAIT_TIMEOUT: Lock wait timeout exceeded; try restarting transaction:

This error occurs when you modify the same data using multiple modules. It is caused by SQL transactions.

When any SQL module is executed, then it starts the transaction (1), and the transaction is finished after the scenario is fully executed. If another module tries to access the same data used in another unfinished transaction (1), then it has to wait until the previous transaction (1) is finished. This, however, never happens because the first transaction (1) will be finished when the scenario is finished.

Solution

Turn on Auto-commit. It finishes (commits) every transaction immediately after the module execution is done.

1. Open Scenario settings.

2. Enable the Auto commit checkbox.

3. Confirm the settings dialog by clicking the OK button.
