Custom function to return Record Selection Criteria

Question

<p>Here&#39;s what I need to do. There will be two prompts for range of dates; say, Begin date and End Date on almost all of the reports here. But it is not mandatory to enter Begin Date nor end date. So depending on the data the user enters we have to build the where clause.</p><p>So, to achive this I am trying to write a custom function which accepts the column name , and data from the parameters in the report. </p><p>my_func(col_nme, bgn_date, end_date) .. </p><p>This function does all the validations and returns a string depending on the data entered by the user. </p><p> Eg., if user entered only begin date then it will return col_nme <= bgn_date<br />      if user entered both dates then col_nme between bgn_date and end_date</p><p> And I am trying to user this complete clause in my record selection of the report. </p><p>In Record Selection call my_func({Query.Eff_date},p_bgn_date,p_end_date) </p><p>It is not accepting it since the function returns it as a string and the Reord selection should return a bolean. </p><p>Can any one let me know how to get this functionality in my report. </p><p>&#160;</p><p>ANy other suggestions to achieve this would be a great help<br />Thanks a lot in advance. </p>

Answer 1

as long as you have discrete and multi values checked on for the parameter, the resulting array is all you need.
In the RSF, the desired results will be returned by a REALLY simple boolean statement
{table.field} in {?my param}
"Like" may replace "in"Â for some cases.
Try it, you'll like it. :)Â
