Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
HCL OneDB™ extensions and DataBlade® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.
TimeSeries Data User's GuideThe HCL OneDB™ TimeSeries Data User's Guide contains information to assist you in using the TimeSeries extension with HCL OneDB™.
Time series API routinesThe time series application programming interface routines allow application programmers to directly access a time series datum.
The ts_get_all_cols() procedure

The ts_get_all_cols() procedure

The ts_get_all_cols() procedure loads the values in the element into the values and nulls arrays.

Syntax

void 
ts_get_all_cols(ts_tsdesc  *tsdesc, 
                 ts_tselem  tselem, 
                 MI_DATUM   *values, 
                 mi_boolean *nulls, 
                 mi_integer off)

tsdesc: A time series pointer returned by ts_open().
tselem: The element to extract data from.
values: The array to put the column data into. This array must be large enough to hold data for all the columns of the time series.
nulls: An array that indicates null values.
off: For a regular time series, off is the offset of the element. For an irregular time series, off is ignored.

Returns

None. The values and nulls arrays are filled in with data from the element. The values array is filled with values or pointers to values depending on whether the corresponding column is by reference or by value. The values in the values array must not be freed by the caller.
