Are you looking to find what is the SPLIT() functions within the Snowflake cloud data warehouse or maybe you are looking for a solution about how to use the split functions in the Snowflake? Or may be you are looking for how to split string to column in the Snowflake. If you are looking for any of these problem solutions then you have landed on the correct page. I will also show you what and how to use SPLIT() function. I will explain the SPLIT() functions by taking a practical examples. So don’t waste time let’s start step by step guide to understand what is the SPLIT() expression in detail.

What is SPLIT() Function?
SPLIT() function is used to split a given string with the help of given separator and returns the result in an array of strings.
If contiguous split strings in the source string or the presence of the split string at the beginning or end of source string then results in empty string in the output. If the given separator is empty then the result will be same as source string.
Syntax of the Spit Function in Snowflake
-- Syntax :
SPLIT( String, Separator )
SPLIT() Argument Details :
| First Input Parameter | String value ( Mandatory ) |
| Second Input Parameter (Separator) | String value ( Optional ) |
| Output | Array of split string |
First Input Parameter:
Text that need to be split into parts.
Second Input Parameter Separator:
Separator string based on which the input string will get split.
Output:
The data type of returned output is an ARRAY.
Example of SPLIT function in Snowflake:
--Example-1
select split('127.0.0.1', '.');
+-------------------------+
| SPLIT('127.0.0.1', '.') |
|-------------------------|
| [ |
| "127", |
| "0", |
| "0", |
| "1" |
| ] |
+-------------------------+
As we can see the above example splits the localhost IP address 127.0.01 into an array consisting of four parts.
--Example-2 :
select split('|a||', '|');
+--------------------+
| SPLIT('|A||', '|') |
|--------------------|
| [ |
| "", |
| "a", |
| "", |
| "" |
| ] |
+--------------------+
As we can see the above example-2 which was split a string that contains vertical Pipe as separator ( Above output contains empty strings ).
