A value entered into an INTERVAL column need not include the full range of time units that were specified in the data-type declaration of the column. For example, you can enter a value of HOUR TO SECOND precision into a column defined as DAY TO SECOND. A value must always consist, howev...

Data should be provided in fixed intervals (for example, always ending at fixed 15 minute increments of the hour.) Valid time values are 0015, 0030…2345, 0000. Data should be grouped by service_point_id and date, and ordered by time.Important...

Use typeof operator to find data type of any variable like this: typeof is an unary operator that is placed before a single operand which can be of any type. Its value is a string that specifies the type of operand. var variable1 = "Hello"; var autoSaveInterval; this.autoSaveInterval...
If SECOND (or a larger time unit) is the largest_qualifier, the declaration of an INTERVAL data type can optionally specify n, the precision of the largest time unit (for n ranging from 1 to 9); this is not a feature of DATETIME data types. If smallest_qualifier is FRACTION, you can...
The value of allintervalvariables can be printed using thedumpcommand. New values can be assigned tointervalvariables using theassigncommand. All generic functionality that is not data type specific should work. For additional details ondbxfunctionality, seeDebugging a Program Withdbx....
