Description
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 |
|---|---|
| <expC1> | The string to be searched |
| <expC2> | The start delimiter. If <expC2> is an empty string, the string is extracted from the start of <expC1> to the first occurrence of <expC3>. |
| <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). |
Settings:
| Bit | Value (additive) | Setting |
|---|---|---|
| 0 | 1 | Search is case-insensitive. |
| 1 | 2 | End delimiter is not required. If <expC3> is specified, but not found, the string will be extracted from <expC2> to the end of <expC1> |
| 2 | 4 | The delimiters are included in the return string. |
