pyflink.table.expression.Expression.split

Expression.split(delimiter) → Expression

Returns an array of substrings by splitting the input string based on the given delimiter. If the delimiter is not found in the string, the original string is returned as the only element in the array. If the delimiter is empty, every character in the string is split. If the string or delimiter is null, a null value is returned. If the delimiter is found a t the beginning or end of the string, or there are contiguous delimiters, then an empty string is added to the array.

Added in version 1.12.0.
