    I’ve already used ModDBExport module,but the data is not imported into the database(postgresql) . Before that, I had been configured as a document .
    DROP TABLE IF EXISTS cnldata;

    — Create channel data table
    CREATE TABLE cnldata (
    datetime timestamp NOT NULL,
    cnlnum integer NOT NULL,
    val double precision NOT NULL,
    stat integer NOT NULL,
    PRIMARY KEY (datetime, cnlnum)
    );

    CREATE INDEX ON cnldata (cnlnum);

    The above runs at postgres ,and The insert statement runs in current data in the ModDBExport attribute

    1.Generate a file that name is KpPost.dll .The file depends on a Npgsql.dll
    2.Use the SetCurData method to set the current value.
    3.KpTestView class inherits the KpView class and then creat input channels.

    I want export to postgresql database by using ModDbExport module,and it is success.
    But the data is constantly exported to postgresql database .so I want to be able to control the export period,or other methods avoid continuous export. I’m not sure if I have a clear description .
