Expressions passed to this function must have the following data types:
- instring = VARCHAR or CLOB
- name_to_search = VARCHAR
- name_delimiters = VARCHAR
- value_delimiters = VARCHAR
- occurrence = INTEGER
The character set of instring, name_to_search, name_delimiters, and value_delimiters can be LATIN or UNICODE. If the parameter character sets are mixed, then all the parameters are converted to UNICODE.
You can also pass arguments with data types that can be converted to the above types using the implicit data type conversion rules that apply to UDFs.
If a delimiter is part of a longer delimiter, the longer delimiter has precedence in the matching process.
Adjacent delimiters are treated as a single delimiter.
