==Description==
The STR_REPLACE() function will search <expC1> or <memofield> and replace text within <expC1> or <memofield> with <expC3> wherever the occurrence of <expC2> is found.  The optional <expN1> specifies the start position for the search in <expC1>.  If this is not specified then the default is 1.  The optional <expN2> specifies the number of occurrences of <expC2> to replace with <expC3>.  If this is not specified, then all occurrences starting from <expN1> are replaced.  This function can be used to remove blank spaces in character strings.  The STR_REPLACE() function returns a character expression that contains the result of the string translation.

Purpose

Function to search for and replace text within a character string or memo field


Syntax

STR_REPLACE(<expC1>, <expC2>, <expC3> | <memofield> [, <expN>])

Description

The STR_REPLACE() function will search <expC3> or <memofield> and replace text within <expC3> or <memofield> with <expC2> wherever the occurrence of <expC1> is found. The STR_REPLACE() function returns a character expression that contains the result of the string replacement.

The optional count argument, <expN>, can be used to return the number of matched and replaced <expC1> strings.


Example

? str_replace("ello", "i","Hello World",nCount)
Hi World
? nCount
         1
