[jira] [Updated] (CALCITE-5772) Add MAP_CONCAT, MAP_FROM_ENTRIES for Spark dialect
[ https://issues.apache.org/jira/browse/CALCITE-5772?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
jackylau updated CALCITE-5772:
------------------------------
Description:
MAP_FROM_ARRAYS (array1, array2)
* Returns a map created from an *array1* and *array2. Note that the lengths of two arrays should be the same
{code:java}
// code placeholder
> SELECT map_from_arrays(array(1.0, 3.0), array('2', '4'));
{1.0:"2",3.0:"4"} {code}
STR_TO_MAP(string[, stringDelimiter[, keyValueDelimiter]])
- Returns a map after splitting the *string* into key/value pairs using delimiters. Default delimiters are ',' for *stringDelimiter* and ':' for *keyValueDelimiter* Both {{pairDelim}} and {{keyValueDelim}} are treated as regular expressions.
*Examples:*
{code:java}
> SELECT str_to_map('a:1,b:2,c:3', ',', ':');
- {"a":"1","b":"2","c":"3"}
> SELECT str_to_map('a');
{"a":null} {code}
> Add MAP_CONCAT, MAP_FROM_ENTRIES for Spark dialect
