In this tutorial, you have learned how to use the SQLite REPLACE() function to replace all occurrences of a substring in a string with a new string. From the value that we get from the LEN function, we subtract 3, as we only want to extract the numbers and want to remove the first three characters from the left of the string in each cell. Phone = REPLACE(phone, '410', '+1-410') Code language: SQL (Structured Query Language) ( sql )įinally, query data from the contacts table to verify if the phone has been updated: SELECTĪs shown clearly in the output, the phone numbers have been updated successfully. RIGHT (A2,LEN (A2)-3) The above formula uses the LEN function to get the total number of characters in the cell in column A. Here are the contents of the contacts table:Īfter that, update the phone area code from local (410) to international one(+1-410): UPDATE Then, query data from the contacts table: SELECTĬontacts Code language: SQL (Structured Query Language) ( sql ) VALUES( 'Lily', 'Bush', '41') Code language: SQL (Structured Query Language) ( sql ) INSERT INTO contacts(first_name, last_name, phone) Next, insert into the contacts table some rows: INSERT INTO contacts(first_name, last_name, phone) We will use the REPLACE() function to replace strings in a table.įirst, create a new table named contacts that consists of four columns: contact_id, first_name, last_name, and phone: CREATE TABLE contacts ( The output is: SQLite REPLACE() string in a table example Here’s the query you would write: Note that the character to remove is optional you can just specify the name of the column if you want to remove the space character: Here’s the result of both queries: Discussion: Use the TRIM function in an SQLite database if you want to trim a string in a table. The following statement uses the REPLACE() function to replace the string 'This' in the string 'This is a cat' with the new string 'That': SELECT REPLACE( 'This is a cat', 'This', 'That') The following example replaces the string 'A' in the string 'AA B CC AAA' with the new string 'Z': SELECT REPLACE( 'AA B CC AAA', 'A', 'Z') Let’s take some examples of using the REPLACE() function.
