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_col_id() function

The ts_col_id() function

The ts_col_id() function takes a column name and returns the associated column number.

Syntax

mi_integer 
ts_col_id(ts_tsdesc *tsdesc, 
         mi_string *colname)

Column numbers start at 0; therefore, the first time stamp column is always column 0.

The number of the column associated with colname.
