该函数的语法如下: regexp_substr(string, pattern, position, occurrence, match_parameter) string:要搜索的字符串。 pattern:要匹配的模式。 position:开始搜索的位置,默认为1。 occurrence:指定要返回的匹配项的序号,默认为1。 match_parameter:指定匹配参数,如'i'表示大小写不敏感。 该函数的应用场景包括但不限...
The purpose of the Oracle LISTAGG function is to allow you toperform aggregation of stringsfrom data in columns. What is string aggregation? Well, it’s a technique similar to concatenation, but it allows you toaggregate data in a GROUP BY, combining strings that have matches in a value in...

• Reads the files as delimited text, and the fields as type STRING. • Assumes that the number of fields in the HDFS files match the number of columns (three in this example). • Assumes the fields are in the same order as the columns, so that CUST_NUM data is in the first ...
