RPAD FUNCTION IN TERADATA
In this article, we will learn about RPAD FUNCTION IN TERADATA
Returns the source_string padded to the right with the characters in fill_string so that the resulting string is length characters.
the name of the database where the function is located.
a character string or string expression.
If the length of source_string is greater than length, source_string is truncated to length characters.
the number of characters in the resulting string
an optional string of characters used to pad the source_string.
The sequence of characters in fill_string is replicated as necessary.
If fill_string is not specified, source_string will be padded to the right with space characters.
Argument Types and Rules
Expressions passed to this function must have one of the following data types:
- source_string = VARCHAR or CLOB
- length = INTEGER, BIGINT, or NUMBER
- fill_string = CHAR, VARCHAR, or CLOB
If any of the input arguments are NULL, the function returns NULL.
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.
The result data type and character set are the same as those of the source_string argument. For example, if the source_string argument has a data type of VARCHAR CHARACTER SET UNICODE, the result data type is ARCHAR CHARACTER SET UNICODE.
The following query returns the result ‘buildingyzy’.
SELECT RPAD('building', 11, 'yz');
The following query returns the result ‘build’.
SELECT RPAD('building', 5, 'yz');
The following query returns the result ‘building ‘. The space character is used by default to pad the source string.
SELECT RPAD('building', 11);
