Database Connection Address

Database connection address reference:

database	url sample
mysql	mysql://username:password@127.0.0.1:3306/testdb
sql server	sqlserver://username:password@127.0.0.1:1433/testdb
postgres	postgres://username:password@127.0.0.1:5432/testdb
oracle	oracle://username:password@127.0.0.1:1521/testdb

Sample

The following is an example of writing device data collected by the data collection module into a MySQL database.

• Filter the points that need to be stored in MySQL in the SQL editor: deviceid, devicename, temp

• Add SQL Sink action
  • Click the Test Connection button to test the database connection status
  • Write deviceid, devicename, temp data into table table1 of MySQL database test.

TIP

Table table1 needs to be created in advance in the MySQL database, and fields with the same column names deviceid, devicename, and temp exist, and the data types must be consistent.
