If a TimeStamp values has no fractional component, then its length is 19 digits If it has a fractional component, its length is 20 digits, plus the length of the fractional component. The lengths of the components of a TimeStamp are the same as for Time and Date, except that the default length of the fractional part of the time component is six digits rather than zero. Stores both date and time information in the format YYYY-MM-DD HH:MM:SS. The default length of the fractional part is zero. The seconds values is also two digits, may include a optional fractional part, e.g., 09:55:25.248. Stores hour, minute, and second values of a time in the format HH:MM:SS. The year value is four digits the month and day values are two digits. Stores year, month, and day values of a date in the format YYYY-MM-DD. Stores double-precision floating-point numbers. Stores floating-point numeric values with a precision that you specify, i.e., FLOAT (5). Text up to the amount specified by the database for this column type. For example, VARCHAR (20) specifies a VARCHAR column with a maximum length of 20 characters. Text or VarChar, 5, Stores alphabetic data, in which the number of characters vary from row to row, but you don't want to pad the unused characters with blanks. If a row contains fewer than the maximum number of characters for the column, the remaining characters will be padded with blanks. Stores alphabetic data, in which you specify the maximum number of characters for the column, i.e., CHAR (20) for a 20 character column. SQLiteDatabase supports 8-byte integer columns and the ColumnType evaluates to 19 (64-bit integer). The maximum number of digits is implementation-specific. If you are using another data source, check the documentation of your data source.Ī numeric data type with no fractional part. SQLiteDatabase supports 4-byte smallints. The maximum number of digits is implementation-specific, but is usually less than or equal to INTEGER. Stores the byte representation of a character string.Ī numeric data type with no fractional part. Use the table below to identify the Column Type based on the index Integer (Not all databases use all these types).ĭenotes the absence of any value, i.e., a missing value. Returns an integer value for the data type of the passed column. AddRow ( "" ) For i As Integer = 0 To rs. Name Next ' Add the data from the table While Not rs. WidthExpression = "100" For i As Integer = 0 To rs. RemoveAllRows ' Add the DB columns as the headers for the ListBox dataList. Sub PopulateListBox ( dataList As DesktopListBox, rs As RowSet ) If rs Is Nil Then Return ' set up listbox state for population dataList. This moves the RowSet pointer so that BeforeFirstRow is True: The only way to set the RowSet to be before the first row is to use RowSet, which is not supported by all data sources. Returns True when the RowSet is before the first row or the RowSet is empty.Ī new RowSet is always at the first row (if any rows were returned). RemoveAllRows ' Add the DB columns as the heades for the ListBox dataList. Sub PopulateListBox ( dataList As DesktopListbox, rs As RowSet ) If rs Is Nil Then Return ' set up listbox state for population dataList. Reporting bugs and making feature requests.
