Overview

FunctionDescription

...

CONCATENATEUse the '+' (plus) operator to concatenate strings or a combination of strings and other type values to produce a single string value

...

Syntax

Code Block
string1 + string2 + ... + value1 + ...
  • string1 - The first string that you want to concatenate.
  • string2 - The second string that you want to concatenate.
  • value1 - A value of some type of number, date or boolean that you want to add to the new string value.

Return type

  • string

Examples

  • 12 + " kilometers" = "12 kilometers"
  • "This statement is " + TRUE + "." = "This statement is true."
  • "I was born on " + Me.birthDateAndTime + "."  (Me.birthDateAndTime = 01-12-1970 23:00:45) = "I was born on Tue Dec 01 23:00:45 CET 1970."

The CONCAT function is identical to the JOIN function.

Examples

Suppose you have a model containing the following attributes.

 

...

 

  • JOIN ( Person.name , Person.date_of_birth , ";" ) = "John;Sun Jan 01 00:00:00 CET 1995"
  • JOIN ( Person.name , Person.name , "@" ) = "John@John"
  • JOIN ( Person.name , Person.family_name , YEARS BETWEEN Person.date_of_birth AND DATE ( 2015 , 01 , 01 ) , ";" ) = "John;;20"

MATCH

...

a string pattern to another string and returns TRUE if the string exactly matches the pattern, and otherwise FALSE. The MATCH function is case-sensitive.

...

Syntax

...

  • pattern - An attribute of base type string or a string value. String must be a valid regular expression. The regular expressions used in several Blueriq Studio functions are common Java 1.4 expressions. For a complete documentation we refer to the online java documentation.
  • string - String value, attribute of base type string or an expression that results in a string value.

Return type

  • boolean

Examples

If the attribute File.name is of base type string and its value is "Thisfile_1.doc" then

  • MATCH ( "Thisfile_1.doc" , File.name ) = TRUE
  • MATCH ( File.name , "Thisfile_1.doc" ) = TRUE
  • MATCH ( " Thisfile_1.doc" , File.name ) = FALSE
  • MATCH ( "thisfile_1.doc" , File.name ) = FALSE
  • MATCH ( "[A-Z]hisfile_1.doc" , File.name ) = TRUE
  • MATCH ( "[a-z]hisfile_1.doc" , File.name ) = FALSE
  • MATCH ( "Thisfile_[0-9].doc" , File.name ) = TRUE
  • MATCH ( ".............." , File.name ) = TRUE
  • MATCH ( ".*" , File.name ) = TRUE
  • MATCH ( "**" , "**" ) results in an error message, because "**" is not a valid regular expression
FINDLooks

FIND

...

for a string pattern within another string and returns the first matching characters. The function is case-sensitive

...

Syntax

Code Block
FIND ( pattern , string )
FIND ( pattern , string , startIndex )

  • string - An attribute of base type string or an expression that results in a string.
  • startIndex - A positive integer value indicating at which character of the string the search should start (inclusive). This can be either an attribute of base type integer, an expression that results in an integer or a constant integer value. The first character starts at index 0.

Return type

  • string
