What is the syntax for finding a specific string in SQL…

In SQL, the LIKE operator is used to determine if a column contains a certain string. The LIKE operator can be used with wildcards to specify the pattern to match.

Here are some examples of using the LIKE operator for string matching:

1. Match columns that start with the specified string:

SELECT * FROM table_name WHERE column_name LIKE 'string%';

1. Columns ending with a specified string:

SELECT * FROM table_name WHERE column_name LIKE '%string';

1. Match columns that contain a specified string.

SELECT * FROM table_name WHERE column_name LIKE '%string%';

1. Columns that start and end with specified strings:

SELECT * FROM table_name WHERE column_name LIKE 'string%string';

1. Performing fuzzy matching using wildcards.

1. ‘%’ is used to match any character (including zero characters)
2. ‘_’ represents matching any single character

SELECT * FROM table_name WHERE column_name LIKE 'str_ng%';

The column_name in the above example is the name of the column to be matched, the table_name is the name of the table to be queried, and the string is the string to be matched.

Please note that in certain databases (such as MySQL), the LIKE operator is case-sensitive by default. If you need to perform a case-insensitive match, you can use the UPPER() or LOWER() functions to convert both the column and the string to either uppercase or lowercase before performing the matching operation. For example:

SELECT * FROM table_name WHERE LOWER(column_name) LIKE LOWER('%string%');
