INITCAP FUNCTION IN TERADATA

Dear Readers,

In this article, we will learn about INITCAP FUNCTION IN TERADATA

Purpose 

Modifies a string argument and returns the string with the first character in each word in uppercase and all other characters in lowercase. Words are delimited by white space or characters that are not alphanumeric.

Syntax 

TD_SYSFNLIB :

the name of the database where the function is located.

string :

a character string or string expression.

If string is NULL, the function returns NULL.

ANSI Compliance

This is a Teradata extension to the ANSI SQL:2011 standard.

Argument Types and Rules

Expressions passed to this function must have one of the following data types:

CHAR, VARCHAR, or CLOB

You can also pass arguments with data types that can be converted to the above types using the implicit data type conversion rules that apply to UDFs.

Note: The UDF implicit type conversion rules are more restrictive than the implicit type conversion rules normally used by Teradata Database. If an argument cannot be converted to the required data type following the UDF implicit conversion rules, it must be explicitly cast.

Result Type

The result data type and character set are the same as those of the input string. For example, if the input string has a data type of VARCHAR CHARACTER SET UNICODE, the result data type is VARCHAR CHARACTER SET UNICODE.

Example

The following query returns the result ‘Hello World’.
