This function replaces part of a text string with a different text string (based on specified number of bytes).
REPLACEB(old_text,start_char,num_bytes,new_text)
This function has the following arguments:
| Argument | Description |
|---|---|
| old_text | Refers to the original text in which you want to replace characters. |
| start_char | Refers to the starting position in the original text to begin the replacement. |
| num_bytes | Refers to the number of bytes in the original text that you want to replace with characters from the new text. If this function is not an integer, the number is truncated. |
| new_text | Refers to the new text that replaces characters in the original text. |
The REPLACEB function counts 2 bytes per character, but this happens only when a DBCS language is set as the default language.
Accepts string data for the old_text argument, numeric data for the start_char argument, numeric data for the num_bytes argument, and string data for the new_text argument. Returns string data.
REPLACEB("lovely",1,3,"lo") gives the result loely.
REPLACEB("rosy",1,3,"!") gives the result !y.
