It usually consists of three arguments i.e., string, delimiter, and position.

In MySQL, we use SUBSTRING_INDEX() to split the string. MySQL Split concept comes into the picture if you are intended to split the string.

For such cases, we use the split concept.

For example, we could be sometimes willing to separate the column values which consists of delimiter.

MySQL split concept is to split the string related data.

SUBSTRING_INDEX((SUBSTRING_INDEX(E_ADDRESS,' ',3)),' ',-1) AS ADDRESS3

SUBSTRING_INDEX((SUBSTRING_INDEX(E_ADDRESS,' ',2)),' ',-1) AS ADDRESS2, SUBSTRING_INDEX((SUBSTRING_INDEX(E_ADDRESS,' ',1)),' ',-1) AS ADDRESS1, Now we can split into an individual instead of the above output SUBSTRING_INDEX(E_ADDRESS,' ',3) AS ADDRESS3/* - substring declare-*/ SUBSTRING_INDEX(E_ADDRESS,' ',2) AS ADDRESS2, /* - substring declare-*/ SUBSTRING_INDEX(E_ADDRESS,' ',1) AS ADDRESS1, /* - substring declare-*/ Now let us split the column values of “E_ADDRESS” using the SUBSTRING_INDEX () Output for the above table is as below: – Insert into EMPLOYEE_ADDRESS values (10, 'Jhope', 'Bangalore', '189-1-26 Seoul South korea') Insert into EMPLOYEE_ADDRESS values (9, 'V', 'AP', '12-89-26 Busan South korea') Insert into EMPLOYEE_ADDRESS values (8, 'Jk', 'Bangalore', '166-0 Busan South korea') Insert into EMPLOYEE_ADDRESS values (7, 'Jimin', 'UP', '234-0 Busan South korea') Insert into EMPLOYEE_ADDRESS values (6, 'Ji eun', 'Bangalore', '167-4 Seoul South korea') Insert into EMPLOYEE_ADDRESS values (5, 'Hamington', 'UP', '126-09 Busan South korea')

Split concat how to#

I don't know how to overcome this problem please hep me. See here I splitted my concat data into separate rows it should separate into more than three columns but it only separate into three columns which makes rest of the data left out. Insert into EMPLOYEE_ADDRESS values (4, 'Ben', 'UP', '10-34 Seoul South korea') It is second time I am really disappointed with another operator. Insert into EMPLOYEE_ADDRESS values (3, 'Will', 'Tamilnadu', '91-27 Seoul South korea' ) Insert into EMPLOYEE_ADDRESS values (2, 'Sohan', 'Bangalore', '11-26 Busan South korea' ) Insert into EMPLOYEE_ADDRESS values (1, 'Sam', 'MP', '12-1-26 Seoul South korea') Now let us create the table and split the string by applying the SUBSTRING_INDEX (). Select substring_index ('ABC| BGF| TYH ','|', -3) AS STRING Select substring_index ('ABC| BGF| TYH ','|', -2) AS STRING Select substring_index ('ABC| BGF| TYH ','|', -1) AS STRING Here in the above example the delimiter is ‘|’. Select substring_index ('ABC| BGF| TYH ','|',3) AS STRING Select substring_index ('ABC| BGF| TYH ','|',2) AS STRING Select substring_index ('ABC| BGF| TYH ','|',1) AS STRING Now let us see how to split the columns using the SUBSTRING_INDEX (). If the count value is positive, it returns the value from the left to the final delimiter. If the count is a negative value, it returns the value from the right to the final delimiter. Based on the count occurrence the substring will be returned. Here we are specifying the string, delimiter, and count.
