TRANSLATE(string, char_to_remove, char_to_replace)
﻿
Argument
Data Type
Description
string
CHAR 
A string to have specific characters transposed, based on the char_to_remove and char_to_replace values.
char_to_remove
CHAR
The characters to be removed from string.
﻿
Characters specified in the char_to_remove set are replaced with characters in the char_to_replace set based on the corresponding index position. 
﻿
If char_to_remove is longer than char_to_replace, occurrences of the extra characters are removed.
char_to_replace
CHAR
The characters to replace the removed characters in char_to_remove.

Arguments	Data Type	Description
value1	BINARY, HASH or CHAR	A value to concatenate with value2. If one argument is a character value, the other is also cast to a string.
value2	BINARY, HASH or CHAR	A value to concatenate with value1. If one argument is a character value, the other is also cast to a string.

Argument	Data Type	Description
char1	CHAR	A string to evaluate for whether it ends with char2.
char2	CHAR	A string to evaluate for whether char1 ends with it as a substring.

Argument	Data Type	Description
char	CHAR	A string to evaluate for the first index position where char_substring appears.
char_substring	CHAR	A string to evaluate for where it first appears in char.

Argument	Data Type	Description
char	CHAR	A string to be modified by returning the number of characters equal to integer.
integer	INT	The number of characters to return from the char string. If integer is negative, the function returns all but the last integer characters.

Argument	Data Type	Description
substring	CHAR	A substring to be found for its first position in string.
string	CHAR	A string to be evaluated for the first position of substring.
offset	INT	Optional. A number of index positions in string to offset the search for the substring value. This index position must be a positive integer, and it starts from the left of string.

Argument	Data Type	Description
string	CHAR	A string to be padded on its left side with additional characters, so that it equals the length value.
length	INT	The number of characters for string to total. If the string is already longer than length, the function truncates string to equal the length value.
pad_character	CHAR	Optional. A string of one or more characters to use to pad string in order to equal the length value. If not provided, pad_character uses a whitespace character to pad.

Argument	Data Type	Description
string	CHAR	A string to be trimmed on its left side.
trim_character	CHAR	Optional. A string of one or more characters to be trimmed from the left side of string. Each character is trimmed individually, not as a cohesive substring. If you do not specify this argument, this value defaults to removing all whitespace from the left side of string.

Argument	Data Type	Description
string	CHAR	The string to search, specified as a character string.
pattern	CHAR	The regular expression pattern to use in the search, specified as a character string.
position	INT	Optional. The position, specified as a positive integer, that represents the position within the string string where to begin the search, based on the number of characters. If this integer exceeds the number of characters in string, then the function returns 0. The default value is 1.
parameters	CHAR	Optional. Parameters, specified as a character string, that contains one or more characters representing regular expression options for pattern matching. Supported options are: c — Perform case-sensitive matching. The Ocient System enables this type of matching by default. i — Perform case-insensitive matching. p — Interpret the pattern using the Perl Compatible Regular Expression (PCRE) dialect. For details, see PCRE. The Ocient System enables this interpretation by default.

Argument	Data Type	Description
string	CHAR	A string to be altered by replacing all instances of substr_to_remove with substr_to_replace.
substr_to_remove	CHAR	A substring to remove from string, replacing all instances with the substr_to_replace value. If substr_to_remove is the empty string, string will be returned, including NULL values.
substr_to_replace	CHAR	A substring to replace all instances of substr_to_remove.

Argument	Data Type	Description
char	CHAR	A string to be evaluated to return the number of trailing characters equal to integer.
integer	INT	The number of characters of return from the end of the char string. If integer is negative, the function returns all but the first integer characters.

Argument	Data Type	Description
string	CHAR	A string to be padded on its right side with additional characters, so that it equals the length value.
length	INT	The number of characters for string to total. If the string is already longer than length, the function truncates string to equal the length value.
pad_character	CHAR	Optional. A string of one or more characters to use to pad string in order to equal the length value. If not provided, pad_character uses a whitespace character to pad.

Argument	Data Type	Description
string	CHAR	A string to be evaluated to return a substring, based on the integer value.
integer	INT	The number of characters to return from the right side of the string value. This value must be positive.

Argument	Data Type	Description
string	CHAR	A string to be trimmed on its right side.
trim_character	CHAR	Optional. A string of one or more characters to be trimmed from the right side of string. Each character is trimmed individually, not as a cohesive substring. If you do not specify this argument, this value defaults to removing all whitespace from the right side of string.
