Retrieve a specific string from a column in a table using MySql.

In MySQL, you can use the SUBSTRING and LOCATE functions to retrieve a specific string from a column in a table.

Here’s how you can use SUBSTRING and LOCATE in a SELECT statement:

//syntax
SELECT SUBSTRING(column_name_or_string, LOCATE('string_to_find', column_name_or_string) + LENGTH('string_to_find'), LENGTH(column_name))
FROM table_name
//example
SELECT SUBSTRING('Prefix:31/12/2022 Saturday Suffix:08/01/2023 Sunday', LOCATE('Suffix:', 'Prefix:31/12/2022 Saturday Suffix:08/01/2023 Sunday') + LENGTH('Suffix') + 1) AS Suffix

//output
08/01/2023 Sunday

In this example, column_name_or_string is the name of the column you want to search, string_to_find is the string you’re looking for, table_name is the name of the table, and LENGTH is a built-in MySQL function that returns the

Use of LOCATE() function on MySql:-

The LOCATE function in MySQL is used to search for a specified string within a column in a table and returns its position within the column. If the specified string is not found, LOCATE returns 0.

The basic syntax of the LOCATE function is as follows:

LOCATE(string_to_find, column_name)

Here, string_to_find is the string you’re looking for, and column_name is the name of the column you want to search.

You can use the LOCATE function in a SELECT statement to retrieve only the rows where the specified string is found:

SELECT * FROM table_name
WHERE LOCATE('string_to_find', column_name) > 0;

SELECT LOCATE('to', 'string_to_find')

output
8

You can also use LOCATE in combination with other functions, such as SUBSTRING, to extract a specific portion of a string based on the position of a substring.
