Example: lrd_save_ret_param | Correlating Statements Functions

Saves a return-parameter to a parameter

    LRDRET lrd_save_ret_param( LRD_CURSOR *mptCursor, unsigned int muiRetParamNum, unsigned long muliOption, char *mpszParamName );

mptCursor | A pointer to an LRD_CURSOR structure.
muiRetParamNum | A "0" indicates the return status. A non-zero value indicates the return-parameter number (DbLib).
muliOption | One of the Save Return Parameter Options.
mpszParamName | A pointer to the parameter name using alpha-numerical characters, enclosed by quotation marks.

The lrd_save_ret_param function saves the value of a stored procedure's return-parameter, to a parameter. If the function cannot retrieve the return-parameter, the parameter is marked as uninitialized. This function is used for Correlating Database Statements.

To generate an lrd_save_ret_param function, right click on the value in the grid that you want to correlate (following lrd_result_set) and choose Create Correlation. After prompting you for a parameter name, VuGen places an lrd_save_ret_param function before the grid.

For more details refer to the DbLib documentation for dbretdata and the Function Header File, Lrd.h.
