💻 String Functions in SQL If you're working with databases, string manipulation is a must have! Here is a quick overview of common SQL string functions 👇 --- 📝 1. CONCAT() - Description: Concatenates two or more strings. - Syntax: SELECT CONCAT(string1, string2, ...) AS concatenated_string - Example: SELECT CONCAT(first_name, ' ', last_name) AS full_name --- 📝 2. SUBSTRING()/SUBSTR() - Description: Extracts a substring from a string. - Syntax: SELECT SUBSTRING(string FROM start_position FOR length) AS substring - Example: SELECT SUBSTRING(product_name FROM 1 FOR 5) AS short_name --- 📝 3. CHAR_LENGTH()/LENGTH() - Description: Returns the length of a string. - Syntax: SELECT CHAR_LENGTH(string) AS length - Example: SELECT CHAR_LENGTH(product_name) AS product_name_length --- 📝 4. UPPER() - Description: Converts all characters to uppercase. - Syntax: SELECT UPPER(string) AS uppercase_string - Example: SELECT UPPER(first_name) AS upper_name --- 📝 5. LOWER() - Description: Converts all characters to lowercase. - Syntax: SELECT LOWER(string) AS lowercase_string - Example: SELECT LOWER(last_name) AS lower_name --- 📝 6. TRIM() - Description: Removes specified prefixes/suffixes or whitespace from a string. - Syntax: SELECT TRIM([LEADING | TRAILING | BOTH] characters FROM string) AS trimmed_string - Example: SELECT TRIM(TRAILING ' ' FROM full_name) AS trimmed_name --- 📝 7. LEFT() - Description: Returns a specified number of characters from the left of a string. - Syntax: SELECT LEFT(string, num_characters) AS left_string - Example: SELECT LEFT(product_name, 5) AS left_product_name --- 📝 8. RIGHT() - Description: Returns a specified number of characters from the right of a string. - Syntax: SELECT RIGHT(string, num_characters) AS right_string - Example: SELECT RIGHT(order_number, 4) AS right_order_number --- 📝 9. REPLACE() - Description: Replaces occurrences of a substring within a string. - Syntax: SELECT REPLACE(string, old_substring, new_substring) AS replaced_string - Example: SELECT REPLACE(description, 'old', 'new') AS updated_description I have curated essential SQL Interview Resources👇 https://topmate.io/analyst/864764 Like this post if you need more 👍❤️ Hope it helps :)
