![]() ![]() This function acts like a SUM() for strings. Given a URL string, returns the domain as a string.Ĭoncatenates values from each record into a single comma-delimited string. Google BigQuery Specific Functions DOMAIN(string_url) Returns the text of the first matching node. XPATH_SHORT('15 ','sum(value/*)') = 6 XPATH_STRING(XML string, XPath expression string) XPATH_SHORT(XML string, XPath expression string) XPATH_LONG(XML string, XPath expression string) Returns the numerical value of the XPath expression, or zero if the XPath expression cannot evaluate to a number. XPATH_INT(XML string, XPath expression string) XPATH_FLOAT(XML string, XPath expression string) Returns the floating-point value of the XPath expression. ![]() XPATH_DOUBLE(XML string, XPath expression string) Returns true if the XPath expression matches a node or evaluates to true. ![]() XPATH_BOOLEAN(XML string, XPath expression string) The query parameter is defined by the key. Returns the value of the specified query parameter in the given URL string. PARSE_URL('', 'HOST') = 'PARSE_URL_QUERY(string, key) Valid url_part values include: 'HOST', 'PATH', 'QUERY', 'REF', 'PROTOCOL', 'AUTHORITY', 'FILE' and 'USERINFO'. Returns a component of the given URL string where the component is defined by url_part. Returns the JSON object within the JSON string based on the JSON path. Note: Only the PARSE_URL and PARSE_URL_QUERY functions are available for Cloudera Impala data sources. This function is available for Text File, PostgreSQL, Tableau Data Extract, Microsoft Excel, Salesforce, Vertica, Pivotal Greenplum, Teradata (version 14.1 and above), and Oracle data sources. If index is 0, the entire string is returned. The substring is matched to the nth capturing group, where n is the given index. Returns the portion of the string that matches the regular expression pattern. REGEXP_EXTRACT_NTH(string, pattern, index) This function is available for Text File, Hadoop Hive, Google BigQuery, PostgreSQL, Tableau Data Extract, Microsoft Excel, Salesforce, Vertica, Pivotal Greenplum, Teradata (version 14.1 and above), Snowflake, and Oracle data sources. This function is available for Text File, Google BigQuery, PostgreSQL, Tableau Data Extract, Microsoft Excel, Salesforce, Vertica, Pivotal Greenplum, Teradata (version 14.1 and above), Impala 2.3.0 (through Cloudera Hadoop data sources), Snowflake, and Oracle data sources.įor Tableau data extracts, the pattern must be a constant. Returns true if a substring of the specified string matches the regular expression pattern. See the Regular Expressions (Link opens in a new window) page in the online ICU User Guide. For Tableau extracts, regular expression syntax conforms to the standards of the current International Components for Unicode (ICU), an open source project of mature C/C++ and Java libraries for Unicode support, software internationalization, and software globalization. This function is available for Text File, Hadoop Hive, Google BigQuery, PostgreSQL, Tableau Data Extract, Microsoft Excel, Salesforce, Vertica, Pivotal Greenplum, Teradata (version 14.1 and above), Snowflake, and Oracle data sources.įor Tableau data extracts, the pattern and the replacement must be constants.įor information on regular expression syntax, see your data source's documentation. Returns a copy of the given string where the regular expression pattern is replaced by the replacement string. REGEXP_REPLACE(string, pattern, replacement) ![]()
