Hi,
I had a project with a database on MS SQL Server, that used a named query (of type Scalar Query) to perform an INSERT followed by a SELECT @@identity. This worked well.
Then our client requested that we switch to MariaDB, so I modified the select part of the query to be SELECT LAST_INSERT_ID(). This works well in any MariaDB client, but it is not working in Ignition !
I get the following message :
com.inductiveautomation.ignition.client.gateway_interface.GatewayException: java.sql.SQLSyntaxErrorException: (conn=46) You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'SELECT LAST_INSERT_ID()
