How to extract specific part from a string in mysql?

In MySQL, you can extract a specific part from a string using various string functions like SUBSTRING, SUBSTR, and MID. These functions allow you to specify the starting position and length of the desired substring.

Here's an example of how to extract a specific part from a string:

1
2

SELECT SUBSTRING(column_name, start_position, length) AS extracted_string
FROM table_name;

Replace column_name with the name of the column containing the string you want to extract from. Specify the start_position as the index of the first character of the desired substring (starting from 1). And specify the length as the number of characters you want to extract.

Here's another example using the MID function:

1
2

SELECT MID(column_name, start_position, length) AS extracted_string
FROM table_name;

The MID function works similarly to SUBSTRING but takes the start position and length parameters in a different order.

Make sure to replace column_name with the actual column name and table_name with the name of the table containing the data.

Keep in mind that MySQL's string functions are 1-based, meaning the first character of a string is at index 1, not 0.
