Data Logging Application That Stores Data In A Table In A MySQL Database?
Dec 18, 2010I have a data logging application that stores data in a table in a MySQL database. Data with a TimeStamp is logged into the table anytime the data from the sensor changes. This means that there maybe 2 seconds between data points or there maybe 20 seconds between points depending on how the data is changing.
When I need the data I have 2 dates and use this command to fill a table..SELECT FROM myTable WHERE timeStamp > date1 AND timeStamp < date2 This gets all the data that has a TimeStamp between the given dates, but in most case the first date in the returned table will be after date1, so I need to get the data from one row before the date returned in the table to know what the data was at date1.How can I get the data row that immediately precedes the returned data set?
Retrieve Data From A Datagridview Loaded With Data From A Linq Database
Apr 9, 2010I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.
