I have a SQL column with a length of 6. Now want to take only the first char of that column. Is there any string function in SQL to do this?

You can use MYSQL SUBSTRING () Function in this way:

Have a look at this video to understand where to use String Functions with syntax and examples.

LEFT (Col_Name, 1)


SELECT SUBSTRING(Col_Name, 1, 1) AS ExtractString;

Parameters used in the SUBSTRING method is as follows:

        1.  Col_Name: This is required to extract the string.

       2.  1: This is required for start position. Where 1st position in the string is 1.

       3. 1: This is nothing but length which is required to extract the no of characters. It must be greater than equal to 1(or positive no).

Note: LEFT() and SUBSTRING() methods are equal.

You can master these queries and become proficient in SQL queries by enrolling in an industry-recognized SQL certification.
