Replace a text in a Field

niimodin

Hello Experts,

I have a client who has a customized module which creates a field for batch nos in the Item table.

I use to update is using dataport.

I am finally handing over the system to the client and what to design a simple where the client can click a button and the system is updated

for example: I want to replace all : 09C/_ with 10D/_ in the item table.

What function should I use?

Can someone help me

Thanks

check out in Help STRPOS (String) function..
Use this function to search for a substring inside a string.

maybe it is not what you are looking for.. Simplest way without the code is - user hit CTR+H (replace) on list form and use it like in any other application. List form must be editable.. at last for this field

If You like to use function then use some filter, loop table and replace what you have to replace

If You like to use function then use some filter, loop table and replace what you have to replace, You can use CONVERTSR if this only part of string you want replace.

Hi

CONVERTSRT use second and third parameter like a mask, non a search text.

If the string is '09C/_0999' you will obtain '10C/_1000'...

The best solution is to use strpos to find the position of the substring, and do a DELSTR and next INSSTR.

IF rec.FINDSET THEN
  REPEAT

  UNTIL rec.NEXT=0

for example, but.. if You don't know this one I think you should read app. designer guide to know what you are doing

Eto: thanks - i know that.. just made a mistake :whistle:

since i was working on a real str_replace function here my solution

STRREPLACE(haystack : Text[1024];needle : Text[1024];replace : Text[1024]) : Text[1024]

i := STRPOS( haystack, needle );
IF ( i > 0 ) THEN BEGIN

  // clear first needle in haystack
  haystack := DELSTR( haystack, i, STRLEN( needle ) );

  // return previous + replace + rest
  EXIT( COPYSTR( haystack, 1, i - 1 ) +
    replace +
    STRREPLACE( COPYSTR( haystack, i, STRLEN( haystack ) - i + 1 ), needle, replace ) );

END; // needle found

avoids to replace any already replaced values who contain the needle again. \:D/

Thanks for sharing. The previous stringreplace function i found was running forever if you replaced "needle" by "needle two".. ](*,)
