# lrd_save_ret_param

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.

## Return Values

See LRD Return Values.

## Parameterization

You cannot use standard parameterization for any arguments in this function.

## Example

In the following example, the lrd_save_ret_param function, saved two return parameters to parameters. VuGen recorded the call to a stored procedure, and lrd_save_ret_param saved the return values of the stored procedure to the parameters Saved_return_status and Saved_name1_out.

    The original script shows the result grid directly after the lrd_result_set function.

    lrd_bind_placeholder (Csr1, "name15_out", &name15_out_D31, 0, 0);

    lrd_assign_literal (&name16_out_D32, "\xFE\x00\x00\x00\. . . ", 0, 0, 0); lrd_bind_placeholder(Csr1, "name16_out", &name16_out_D32, 0, 0);

    lrd_exec(Csr1, 0, 0, 0, 0, 0);

    lrd_result_set(Csr1, 0 /*Succeed*/, 0, 0);

    lrd_result_set(Csr1, 1 /*No results*/, 0, 0);

After correlation, the lrd_save_ret_param function appears in the script. In this example, lr_output_message displays the value of the parameter.

    lrd_bind_placeholder (Csr1, "name15_out", &name15_out_D31, 0, 0);

    lrd_assign_literal (&name16_out_D32, "\xFE\x00\x00\x00\. . . ", 0, 0, 0); lrd_bind_placeholder(Csr1, "name16_out", &name16_out_D32, 0, 0);

    lrd_exec(Csr1, 0, 0, 0, 0, 0);

    lrd_result_set(Csr1, 0 /*Succeed*/, 0, 0);

    lrd_save_ret_param(Csr1,0,1,"Saved_return_status");

    lrd_save_ret_param(Csr1,1,0,"Saved_name1_out");

    lr_output_message("********** %s ******",lr_string("<Saved_return_status>"));

    lr_output_message("*********** %s *******",lr_string("<Saved_name1_out>"));

    lrd_result_set(Csr1, 1 /*No results*/, 0, 0);
