SELECT REGEXP_REPLACE( 'enterprise ', '\s+$', '') Code language: SQL (Structured Query Language) ( sql ) For example, the following statement removes a space and a tab character from the end of the enterprise string with 1 space and 1 tab characters at the end of the string. One way to remove the leading and trailing whitespace characters from a string is to use REGEXP_REPLACE() function. You can call the TRIM() function multiple times but it is not efficient. However, the TRIM() function only allows you to remove leading and trailing spaces, not all other whitespace characters. Sometimes, your string may contain whitespace characters such as space, tab, line break, etc., that you want to remove. Let’s take a look at the following examples of using the LTRIM(), RTRIM() , and BTRIM() functions to remove the character e from the enterprise string: SELECT LTRIM( 'enterprise', 'e') Code language: SQL (Structured Query Language) ( sql ) SELECT RTRIM( 'enterprise', 'e') Code language: SQL (Structured Query Language) ( sql ) SELECTīTRIM( 'enterprise', 'e') Code language: SQL (Structured Query Language) ( sql ) Removing whitespace characters from a string TRIM(BOTH character FROM string) - BTRIM(string,character) Code language: SQL (Structured Query Language) ( sql ) TRIM(TRAILING character FROM string) - RTRIM(string,character) This is equivalent to the following syntax of the TRIM() function: TRIM(LEADING character FROM string) - LTRIM(string,character) The syntax of LTRIM() and RTRIM() function are as follows: LTRIM(string, ) īTRIM(string, ) Code language: SQL (Structured Query Language) ( sql ) The BTRIM function is the combination of the LTRIM() and RTRIM() functions.The RTRIM() function removes all characters, spaces by default, from the end of a string.The LTRIM() function removes all characters, spaces by default, from the beginning of a string.PostgreSQL provides you with LTRIM, RTRIM() and BTRIM functions that are the shorter version of the TRIM() function. ) - 9100 Code language: SQL (Structured Query Language) ( sql ) PostgreSQL LTRIM, RTRIM, and BTRIM functions Because the TRIM() function only accepts a string as the argument, we have to use type cast to convert the number into a string before passing it to the TRIM() function. The following statement removes leading zero (0) from a number. Last_name = TRIM (last_name) Code language: SQL (Structured Query Language) ( sql ) It uses the TRIM() function to remove both leading and trailing spaces from the first_name and last_name columns. The following statement updates the first_name and last_name columns of the customer table in the sample database with the values that do not have leading and trailing spaces. SELECT TRIM (Ĭode language: SQL (Structured Query Language) ( sql ) See the following examples of removing leading, trailing, and both leading and trailing spaces from strings.
Or just simply: TRIM(string) Code language: SQL (Structured Query Language) ( sql ) PostgreSQL TRIM function examples TRIM(TRAILING FROM string) Code language: SQL (Structured Query Language) ( sql )Īnd to remove all spaces at the beginning and ending of a string, you use the following syntax: TRIM(BOTH FROM string) Code language: SQL (Structured Query Language) ( sql ) The following syntax of the TRIM() function removes all spaces from the end of a string. TRIM( FROM string) Code language: SQL (Structured Query Language) ( sql )įor example, if you want to remove spaces from the beginning of a string, you use the following syntax: TRIM(LEADING FROM string) Code language: SQL (Structured Query Language) ( sql ) The following illustrates the syntax of the TRIM() function. The TRIM() function is very useful when we want to remove the unwanted characters from a string in the database. Note that a string can be any of the following data types: char, varchar, and text.
With the TRIM() function, you can remove the longest string containing a character from the start, end, or both the start and end of a string. By default, the TRIM() function remove spaces (‘ ‘) if you don’t specify explicitly which character that you want to remove.
The TRIM() function removes the longest string that contains a specific character from a string.
