How to convert SQLite values to custom Python types How to adapt custom Python types to SQLite values If you have a phone number column in the format 5556667777, but you want the format (555) 666-7777, you can format it using the SUBSTR() function.How to use placeholders to bind values in SQL queries Z (optional can be omitted) represents the number of characters in the resulting string. Y represents the starting position to obtain the substring (the first character position in the string is always 1). X represents the string you want to obtain a substring from. Obtains a substring of the string you’re working with SUBSTR("column name",'start_position','end_position') If the character appears multiple times in the string, the function returns the position of its first occurrence. Y represents the character whose position you want to obtain. X represents the string that contains the character whose position you want to obtain. Z represents the character or string that is used to replace Y.įinds the position of a character in a string Y represents the character or substring you want to replace. X represents the string that contains the character or string you want to replace. Replaces a character or substring in your string with another character or string REPLACE("column name", 'replace_this', 'with_this') Returns the number of characters in the string LOWER(X)Ĭonverts the string to all lowercase letters UPPER(X)Ĭonverts the string to all uppercase letters REPLACE(X, Y, Z) There are many core functions that you can use for strings and numeric values, but here are some of the common ones you can use for strings: LENGTH(X) Atlassian Analytics uses SQLite to power the non-query Visual SQL steps. ![]()
