Notice that the query above scans the whole table to find the matching rơ. WHERE UPPER(first_name) = 'BRUCE' Code language: SQL (Structured Query Language) ( sql ) For example, the following query will return a row: SELECT To match data case insensitively, you use the UPER function. SELECTįirst_name = 'BRUCE' Code language: SQL (Structured Query Language) ( sql ) For example, the literal string Bruce is different from bruce. When you query the data using the WHERE clause, the database systems often match data case sensitively. UPDATE employeesĮmail = UPPER(email) Code language: SQL (Structured Query Language) ( sql ) Querying data case insensitive using the UPPER function For example, the following statement updates the emails of employees to uppercase. To convert data to uppercase in the database table, you use the UPDATE statement. The query just read the data from the employees table and convert them on the fly. ORDER BY UPPER(last_name) Code language: SQL (Structured Query Language) ( sql ) The following query uses the UPPER function to convert last names of employees to uppercase. Let’s take a look at the employees table in the sample database. (1 row) Code language: SQL (Structured Query Language) ( sql ) The following statement converts the string sql upper to SQL UPPER: SELECT UPPER( 'sql upper') Code language: SQL (Structured Query Language) ( sql ) UPPER UCASE(string) Code language: SQL (Structured Query Language) ( sql ) SQL UPPER function examples It is “there is more than one way to do it”. If the input string is NULL, the UPPER function returns NULL, otherwise, it returns a new string with all letters converted to uppercase.īesides the UPPER function, some database systems provide you with an additional function named UCASE which is the same as the UPPER function. UPPER(string) Code language: SQL (Structured Query Language) ( sql ) The syntax of the UPPER function is as simple as below. If you want to convert a string to lowercase, you use the LOWER function instead. The SQL UPPER function converts all the letters in a string into uppercase. the pattern /mnt/library/%album%/%track% will move the file to /mnt/library/Fans like it/5.Summary: this tutorial shows you how to use the SQL UPPER function to convert a string into uppercase. If you want you can also have an absolute path, by starting the pattern with a slash, eg. %artist%/%album%/%title% will move the file to /home/concentricpuddle/multimedia/music/ Relatively Unknown/Fans like it/Horrible for everyone else.mp3 %album%/%artist% - %title% will move the file to /home/concentricpuddle/multimedia/music/Indie/ Fans like it/Relatively Unknown - Horrible for everyone else.mp3.įor every slash, the file is moved up one directory. %title%_$upper(%album%)-%track%-%artist% will give the filename ‘Sounds Better Than Anything After_THE VINYL LP-10-Before The Fame.mp3’įor a file with the tag, artist=Relatively Unknown, title=Horrible for everyone else, album=Fans like it, track=5 with path, /home/concentricpuddle/multimedia/music/Indie/unsorted/unknown.mp3 %artist% - $num(%track%, 3) - %title% will rename it to ‘Before The Fame - 010 - Sounds Better Than Anything After.mp3’ %artist% - %album% - %track% in the pattern combo will rename it to ‘Before The Fame - The Vinyl LP - Sounds Better Than Anything After.mp3’ Say you had a file named ‘track.mp3’ with the following tag, artist=Before The Fame, album=The Vinyl LP, title=Sounds Better Than Anything After, track=10 and invoked this function. giving “I don’t like an excessively emo guy screeching.” You can even combine/nest them to get what you want as in I don’t like an $lower(%title% $mid(%artist%,2,10)) $lower(%album%). $upper(value) will return ‘VALUE’, $lower(%artist%) will return ‘a guy’. See the scripting functions page for a listing. More editing power is available via the scripting functions. Returning, ‘I don’t like an Excessively Emo A Guy…Screeching’ You can combine fields with any combination of letters as in I don’t like an %title% %artist%…%album%. Using %genre% would return nothing, because there ain’t no genre field in the tag. So %artist% will return ‘A Guy’, %album%, ‘Screeching’ and so on for the others. Individual fields can be referenced by placing them inbetween percent characters (%). Using ‘I wanna write my own.’ as a Format string will return ‘I wanna write my own.’ and write it to the fields you choose. for a file with the tag, artist=A Guy, album=Screeching, title=Excessively Emo, track=2 A Format string can be (almost) any string.
