Function Reference
1010data Insights Platform offers a rich set of functions that may be used in value expressions when creating computed columns and in selection expressions when performing row selections.
String functions
String functions are vector functions that manipulate vectors of strings to provide information about a string or substring, concatenate and split strings, or transform strings based on specified criteria.
Concatenation
repstr(X;L)
Returns the given string with substrings replaced based on a given list of string pairs.

Function Reference
1010data Insights Platform offers a rich set of functions that may be used in value expressions when creating computed columns and in selection expressions when performing row selections.
- All 1010data Functions
  1010data provides a whole range of functions that can provide information and act on your data.
- Time/Date functions
  The time/date functions are vector functions that operate on columns containing time-related data and return specific information about the date/time for each row.
- Group functions (g_functions)
  Group functions, or g_functions, are used to perform operations, such as summarizations, on rows that have the same values in a set of given columns.
- Math functions
  Math functions are vector functions that perform mathematical operations on one or more columns and return a column of results based on the operation.
- Matrix functions
- Categorization functions
  Categorization functions are vector functions that organize data and determine logical groupings. These functions can be used for conditionalizing results and/or bucketing value ranges.
- String functions
  String functions are vector functions that manipulate vectors of strings to provide information about a string or substring, concatenate and split strings, or transform strings based on specified criteria.
  - Length
  - Position
  - Case
  - Substrings
  - Concatenation
    - colunion(X;Y)
      Returns a string consisting of the union of values from a given set of columns concatenated together using the specified separator, sorted in ascending order.
    - g_splice(G;S;O;X;D;N)
      Returns a concatenated list of values ordered in a specified manner within a given group.
    - g_uval(G;S;X;D;N)
      Returns a concatenated list of distinct values within a given group.
    - padleft(X;Y)
      Returns the given string with a certain number of characters, adding blanks at the beginning if necessary.
    - padright(X;Y)
      Returns the given string with a certain number of characters, adding blanks at the end if necessary.
    - r_splice(C;S;D)
      Returns a string consisting of a list of elements across a given set of columns, concatenated together using the specified delimiter.
    - repstr(X;L)
      Returns the given string with substrings replaced based on a given list of string pairs.
    - splice(X;Y)
      Returns a string consisting of the list of given values concatenated together using the specified separator.
    - strembed(X;N;P;Y;D)
      Returns a given string embedded within a template that consists of a string value repeated a particular number of times.
    - strrepeat(X;N)
      Return the given string repeated a certain number of times.
  - Comparison
  - Transformations
  - Regular expressions
- List functions
  List functions are scalar functions that return lists, subsets of lists, and combinations of lists, among other functionality. Lists, along with packages, are compound scalar data types that facilitate programmatic interaction with scalar data values and variables.
- Data-handling functions
  Data-handling functions are vector functions that return a hash value based on an input column or columns.
- Row functions
  Row functions are vector functions that return computational outputs for row inputs, as opposed to column outputs. Row inputs are defined as a space- or comma-separated list of column names.
- SQL compatibility functions
  SQL compatibility functions are functions that treat null values as SQL nulls.
- Financial functions
- System functions
  System functions are special functions in 1010data that return information about users, tables, and other system objects.
- Object functions
  The object functions can be used to check the existence, type, and accessibility of objects such as folders, tables, and queries on the 1010data Insights Platform.
- Miscellaneous functions
  This category of functions contains special functions that don't neatly fit into other categories of functions.

`repstr(X;L)`

Returns the given string with substrings replaced based on a given list of string pairs.

Syntax

repstr(X;L)

Input

Argument	Type	Description
`X`	text	The string on which to apply the function A column name
`L`	text	A space- or comma-separated list of pairs of text strings where `L` has the form: `'old1' 'new1' 'old2' 'new2'`...`'oldx' 'newx'`

Return Value

Returns the text string X with substrings in X replaced based on the string pairs specified in the list L.

If X is N/A, the result is N/A.

Sample Usage


`value`	`list`	`repstr(value;list)`
'abcdefg'	'bc' 'RS' 'ef' 'xy'	'aRSdxyg'
'banana'	'ana' 'ANA' 'b' ''	'ANAna'

Example

In the "Product Master" table (pub.demo.retail.prod), let's say we wanted to replace the occurrences of "OZ" with "OUNCE" in the itemdesc column. To do this, we could create a computed column and use the repstr(X;L) function, specifying the itemdesc column name for the X parameter and the replacement pair of strings 'OZ' and 'OUNCE' in the list for the L parameter.

<base table="pub.demo.retail.prod"/>
<willbe name="repstr_results" value="repstr(itemdesc;'OZ' 'OUNCE')"/>
<colord cols="itemdesc, repstr_results"/>

In this example, the value of "PEPSI 20 OZ" has been changed to "PEPSI 20 OUNCE".
