RE: AW: SQL versus READ for sequential processing

Whoah up there.

Birgitta says that if I use LFs I'm condamned to useing CQE, and your saying that even if I change to DDL there may be no difference?

How exactly do I use the database monitor in iNav?

You should run a database monitor to verify which engine ran you query.
You can do this from Navigator quite easily, from the SQL statement processor. There will be information there about all manner of things, including which engine. Read the help text to learn what you are looking at and where to find the information.

Just because a table was created with DDL, there is no guarantee that SQE will be used to run the query - the way a table is created is NOT one of the criteria for which engine is used.

Not that in my example the table used for the SQL test was created with SQL Create Table. It should have used the SQE.

It ran slowly anyway.
