The STREXTRACT() function extracts a string from <expC1> from between the delimiters specified in <expC2> and <expC3>. The occurrence to be extracted can also be specified.


Parameter Description

<expC3> The end delimiter. If omitted or empty, the string is extracted from <expC2> to the end of <expC1>
<expN1> The occurrence of <expC2> at which to start the extraction. If omitted, the first occurrence is extracted.
<expN2> Optional flags (see below).
