INITCAP¶
Returns the input string (expr
) with the first letter of each word in uppercase and the subsequent letters in lowercase.
Syntax¶
INITCAP( <expr> [ , <delimiters> ] )
Usage notes¶
delimiters
is an optional argument specifying a string of one or more characters that INITCAP uses as separators for words in the input expression:If
delimiters
is not specified, any of the following characters in the input expressions are treated as word separators:<whitespace> ! ? @ " ^ # $ & ~ _ , . : ; + - * % / | \ [ ] ( ) { } < >
If
delimiters
is specified, the specified value overrides all of the characters listed above.
delimiters
supports any UTF-8 characters, including whitespace characters, and is case-sensitive.delimiters
must be enclosed in single quotes, e.g.'x '
(delimiters in this example arex
and blank spaces).delimiters
specified as an empty string (i.e.''
) instructs INITCAP to ignore all delimiters, including whitespace characters, in the input expression (i.e. the input expression is treated as a single, continuous word). The resulting output is a string with the first character capitalized (if the first character is a letter) and all other letters in lowercase.
Collation details¶
Arguments with collation specifications are currently not supported.
Examples¶
This example provides various outputs in different languages using the default delimiters:
