## Reference of NX Sripting Functions

NX, the Ninox query language, is a powerful programming language which allows you to quickly extend Ninox databases with calculations and trigger actions.

While Ninox provides a visual function editor as described in the online manual, it also sports a text-mode for entering more complex expressions. This manual covers the text mode.

Here is an example database covering most of the topics of the tutorial.

#### Basic Arithmetics

NX provides arithmetic operations comparable to most other programming languages:

`1 + 2 = 33 - 2 = 12 * 3 = 610 / 5 = 2`

Arithmetic operations respect the typical operator precedence:

``1 + 2 * 3 = 1 + (2 * 3) =` 7`

Expressions may be enclosed in parentheses:

``(1 + 2) * 3 =` 9`

Note, that NX will automatically remove insignificant parentheses, i. e. if you enter `1 + (2 * 3)` it will store this expression as `1 + 2 * 3`.

#### String Operations

A string, i. e. a sequence of characters, may be entered enclosed in double-quotes:

``"Hello` World!""This` is a` string."`

Strings may be concatenated using the + operator:

``"Hello World!" + " " + "This is a string."` "Hello` World! This is a` String."`

Strings may also be concatenated with other values:

`"Hi` " + 42 = "Hi 42"``2 + " fast " + 4 + " U"      -- "2 fast 4` U"`

To enclose a double-quote within a string, it has to be escaped as “”:

``"Hi, my name is ""Sally""!"``

#### Working with Fields

Most NX functions operate in the context of a specific record. NX gives you access to all fields of that record. Consider a table Customer consisting of fields First Name, Last Name, Street, ZIP, City. To generate the full address line, you may enter:

``Street + ", " + ZIP + " " + City``

Some field names may contain special characters like spaces, dots, colons and so on. Also they may collide with a reserved keyword of NX, like if, then, else. To work around this, field names can be enclosed in single quotes:

``'First Name' + " " + 'Last Name'``

If a field name contains a single quote, this has to be escapes as '' (two single quotation marks/inverted commas):

``'Last year''s total revenue'``

Note, that NX is agnostic to field name changes. That is, if you’ve entered an expression referring to a field and you change that field’s name afterwards it will not have an impact to the expression. This is due to the fact that NX internally stores the expression with a reference to the field’s ID (which cannot me modified). Actually, if you open the function editor again, it will reflect the field’s new name.

#### Working with Table References

NX expressions can navigate along table references as well. Table references are always one-to-may relationships, e.g. one Customer may have many Invoices — where the table reference is defined as from Invoice to Customer (Invoice => Customer).

To display the Customer’s name in an Invoice, you’d write:

`Customer.NameCustomer.'First Name' + " " + Customer.'Last Name'`

Expressions may even jump along multiple hops, consider the case where a Customer has a reference to a Company. You could then display the Company’s in the Invoice as well:

`Customer.Company.Name`

Vice-versa, it’s also possible to get invoice information for a Customer. Remember, that a Customer may have multiple Invoice’s. Thus, an expression referring to the Customer’s invoices will return multiple values. In order to display those values, some kind of aggregation has to be applied. The most common one is to sum up values:

`sum(Invoice.Amount)`

But there are other aggregations as well:

`avg(Invoice.Amount) `     -- the average, ignoring empty field
`cnt(Invoice.Amount)  `   -- the count of non-empty fields
`min(Invoice.Amount)  `   -- the minimum value, ignoring empty fields
`max(Invoice.Amount)  `   -- the maximum value, ignoring empty fields
`first(Invoice.Amount)`   -- the first value, according to Ninox' internal sorting
`last(Invoice.Amount)`     -- the first value, according to Ninox' internal sorting
`concat(Invoice.Amount)`  -- lists all values, separated by ", "

#### Logical Expressions

Logical expressions check if something is the case or not. Most often you’ll need them to create specific filter rules or to make decisions within a calculation. A logical expression either returns true or false. The most common form of a logical expression is a comparison of two values, like:

`Amount > 100`       -- greater than
`Amount < 100`       -- less than Amount >= 100     -- greater than or equal to
`Amount <= 100 `    -- less than or equal to
`Amount = 100`       -- equal
`Amount != 100`     -- not equal

Logical expressions may be combined by and, or, not.

`Age > 12 and Age < 18Status = 1 or Status = 2 or Status = 3not (Status = 4 or Status = 5)Status != 4 and Status != 5`

Note, the operator precedence is not -> and -> or.

#### Making Decisions

In the previous chapter you’ve learned about logical expressions. The result of such an expression may be used in an if / then / else expression:

`if Age < 18 then "Child" else "Grown-up" endif Age < 18 then   if Age < 13  then "Child" else "Teenager"else "Grown-up"end`

Please note, that the then and else part have to return values of the same data type. You can omit the else clause, which returns a null or no operation (void) for the false portion of an if expression. Terminate the if-block with an end statement.

Use switch case for short specific assignments with a default:

`switch <expression> do  case <value>: <result value> case <value2>: <result value2> ...  default: <default value> end`

You can use any number of case statements, but their result values must all be the same data type and the optional default statement must be the last option before end, when used. Result values can also contain multiple instructions, such as assignments and calculations, as long as the returned value data types match each other. Ninox will surround multiple instructions in parenthesis to group them together.

#### Filtering Values

In the chapter “Working with Table References” you’ve already learned how to access multiple values from a table referring the current one — like `sum(Invoice.Amount)`. With logical expressions, these results may also be filtered. A filter expression has to be enclosed in braces:

`sum((Invoice where Status = 2).Amount)sum(Invoice[Status = 2].Amount)`

This will only sum up the Invoice Amounts of Invoices with Status = 2.

You may also order by one field while returning another:

`(select Invoice) order by Amount`

This will return the id's of all Invoice records in the ascending order of Amount.

`select Invoice[Status=2] order by Amount`

Same but limiting the returned id's to a status of 2

#### Calling Functions

NX provides a range of built-in functions allowing you to transform values. A function call has the form:

`function ( argument1, argument2, … )`

Some examples:

`age(Birthdate)` -- The current age of a person with given Birthdate in years

`cos(5)` -- Cosinus of 5

Creating User defined functions locally with the function command:

`function name(argument:data type,...)   ``do <script instructions> end`

Note that a custom function can appear anywhere in a script, but they must come before any call to them, including calling another custom function.

#### Using Variables

Sometimes it can be useful to store the result of a intermediate calculation and do further calculations based on that result. Consider the case where you want to check the age of a person like:

`if age(Birthdate) > 18 then "Grown-up"else if age(Birthdate) > 12 then "Teenager"else "Child"end`

Since `age(Birthday)` is used multiple times, things may be simplified with a variable which stores the result of the age calculation:

`let a := age(Birthdate);`

`if a > 18 then "Grown-up" else if a > 12 then "Teenager" else "Child" end`

A variable is declared with a `let` statement:

`let variable := expression;`

Any expression following that let statement can make use of that variable.

`var variable := expression`

These variables can be modified afterwards, such as in loops.

`let x := 1; ...; x := x + 1;``var y := 1; ...; y := y + 1;`

#### Modifying Data

Some expressions in NX may also modify data. Up to the current release 1.5 of Ninox, this is only allowed for trigger expressions (field option Trigger after update). While further enhancements are planned, modifying data is currently restricted to change the value of record fields.

As an example, consider a table Article with a field Price (number) and another table Invoice Item with fields Article (reference to table Article) and Price (number). After assigning the Article, Ninox shall copy the Article’s Price to the Invoice Item’s Price. This can be achieved with a Trigger after update on Article containing following expression:

`Price := Article.Price`

It is also possible, to update multiple fields, using a semicolon:

`Price := Article.Price;Description := Article.'Article No' + " " + Article.Name`

#### Create Records

With the create statement it’s possible to create new records for a table. The following example creates a new record for the table Person and stores a reference to that record in the variable p. It then assigns a Name to the newly created Person.

`let p := create Person;p.Name := "Sarah Conner"`

You can also duplicate a record to create a new one. "This" is an automatic handle to the current record.

`duplicate(this)`

#### Select Records

Typically, formulas will access data from related tables like descibed above (“Working with Table References”). However, using the select statement there’s also a way to access data from an unrelated tables.

`select Person`

Will look up all Person records, this statement returns an array of record references.

`select Person where ZIP="10000"`

This statement selects only the Persons with the given ZIP value 10000.

Selecting records is useful in many situations, one common case is to calculate the next Invoice ID.

`'Invoice ID' := max((select Invoices).'Invoice ID') + 1`

Selecting records is useful in many situations, one common case is to calculate the next Invoice ID.

`record(tableName, recordId) record(tableName, recordId).fieldName`

Use the record function to return the nth record id of a table as a handle.
Note that recordID is not a position in a sorted view. If a record has been deleted, using that recordID will return a null, since the ID no longer exists and never will again.

#### Delete Records

With the delete command, it’s possible to remove one or more records. Be careful in combination with select, because this may affect a wide range of records with a single call. Some examples:

`delete first(select Person where 'First Name' like "Hans")`

This will look up the first record from the Person table where the name contains "Hans" and remove it.

`delete select Person where 'First Name' like "Hans"`

This will look up the all records from the Person table where the name contains "Hans" and remove all matching records.

`delete select Person`

Will remove any record in the person table.

`delete Customer`

When issued on an invoice record, this will remove the customer that is linked to the current invoice.

`delete Invoices`

When issued on a customer record, this will remove all invoices which are linked to the current customer.

#### Loops

The for statement can be used to loop over arrays of values – e.g. the result of a select.

`for p in (select Person)p.Haircolor := "red"`

This exmple would lookup all Person records (select Person). For each record (stored in the variable p) it would then change the Person‘s Haircolor to red.

Use the `range(From, To)` function to create counting loops:

`for i in range(0, 10) do ... end`

Please note, that for range(From, To), From in inclusive and To is exclusive. To state an example:

`concat(range(0, 4))=> 0, 1, 2, 3concat(for i in range(0, 4) do i*i end)  => 0, 1, 4, 9`

Similar to in range:

`for i from <start> to <end> do ... end for i from <start> to <end> step <step> do ... end`

While loops test the condition at the beginning

`while <expression is true> do ... end`

#### Arrays

Some expressions will return arrays, that is lists of values, as a result. E. g. the reverse end of a relation will return an array of record ids:

`Costumer.Invoices => [ID1, ID2, ID3]`

It is also possible to create an array explicitly with the following syntax:

`let MyArray1 := [1, 2, 81];let MyArray2 := [1, 2, 9 * 9];`
