Roy Lambert NLH Associates ![]() | D2006, EDB 1.06
I thought, whilst waiting for someone to put me out of my misery with the dll external functions I'd have a go at the sql ones. One, or more, of the following is seriously screwed: 1. Me 2. The pdf SQL manual 3. EDBManager Point 1 DECLARE - it looks as though these have to be at the top of the function - found this out when I added SET RESULT = TRUE; above the DECLAREs Point 2 I am unable to get setting the result to work - EDBManager moans about ends, elses or ifs - I seem unable to come up with anything to make it happy. Roy Lambert BEGIN DECLARE _FldStr VARCHAR; DECLARE _CompStr VARCHAR; DECLARE StrLen INTEGER; SET RESULT = TRUE; SET _FldStr = FldStr; SET _CompStr = CompStr; SET _FldStr = REPLACE(' ','',_FldStr); SET _CompStr = REPLACE(' ','',_CompStr); the problem lines and my variations on a theme 1. IF _FldStr =_CompStr THEN SET RESULT = TRUE ELSE SET RESULT = FALSE; 2.; IF _FldStr =_CompStr THEN SET RESULT = TRUE ELSE SET RESULT = FALSE END IF; 3. IF _FldStr <> _CompStr THEN SET RESULT = FALSE; 4. IF _FldStr <> _CompStr THEN SET RESULT = FALSE END; 5. IF _FldStr <> _CompStr THEN SET RESULT = FALSE END IF; END |

Roy Lambert NLH Associates ![]() | That was me - I finally got it to compile (or whatever it is that it does). But it gets worse.
I decided to display the result using select nospacecomp(_work,'01943 442604'), <<<<<<<< sql version _work, spacelesscompare(_work,'01943 442604') <<<<<<<<<<< dll version from cardex And at the appropriate line I get True, 01934 44264, True with all other lines displaying False. Great I thought and added where nospacecomp(_work,'01943 442604') = TRUE Whereupon I get no records displayed. I'm pretty much stuck until I can get this and a load of others working. I chose this cos it was the simple one ![]() Roy Lambert |

Roy Lambert NLH Associates ![]() | I've now tried with defaulting the result to X
DECLARE Res VARCHAR DEFAULT 'X'; .... .... RETURN Res; and that works so its either ignoring a boolean result or my test isn't returning a boolean. I'm currently trying RETURN (FldStr = CompStr); or RETURN (_FldStr = _CompStr); - this one with the spaces stripped and since I'm cutting and pasting a field value I'm pretty sure there should be a match Roy Lambert |

Roy Lambert NLH Associates ![]() | As a final test I did something brilliant - nospacecomp(_work,_work) surprisingly enough this works so its the test of the string I'm passing in that isn't working

Roy Lambert NLH Associates ![]() | Final test before I go and get drunk - this one is fascinating
select _work, showwork(_Work) as alf, showwork('01933 442604') as bert from cardex where showwork(_Work) = showwork('01933 442604') teh function is BEGIN RETURN REPLACE(' ','',FldIn); END and I'm shown all the records, I can eyeball the fact that the spaces are stripped and all but one of the rows shouldn't be there beer here I come!!!!!!

<< DECLARE - it looks as though these have to be at the top of the function - found this out when I added SET RESULT = TRUE; above the DECLAREs >> See the bottom under SQL 2003 standard deviations: http://www.elevatesoft.com/edb1sql_declare.htm "Declarations can only be made at the beginning of the outermost BEGIN..END block in an ElevateDB procedure or function. The standard dictates that declarations can be made anywhere inside of any BEGIN..END block." << I am unable to get setting the result to work - EDBManager moans about ends, elses or ifs - I seem unable to come up with anything to make it happy. >> Use this: CREATE FUNCTION nospacecomp(IN FldStr VARCHAR, IN CompStr VARCHAR) RETURNS BOOLEAN BEGIN DECLARE _FldStr VARCHAR; DECLARE _CompStr VARCHAR; DECLARE Result BOOLEAN DEFAULT TRUE; SET _FldStr = REPLACE(' ','',FldStr); SET _CompStr = REPLACE(' ','',CompStr); IF _FldStr = _CompStr THEN SET RESULT = TRUE; ELSE SET RESULT = FALSE; END IF; RETURN Result; END -- Tim Young Elevate Software www.elevatesoft.com |

<< Whereupon I get no records displayed. >> See my other reply. The issue with the WHERE clause is probably this issue: http://www.elevatesoft.com/scripts/newsgrp.dll?action=openmsg&group=16&msg=3469&page=1#msg3469 -- Tim Young Elevate Software www.elevatesoft.com |

I searched and searched the newsgroups but obviously had the wrong words - no wonder I can't get it to work ![]() Roy Lambert |
