SELECTSTR Function (Code, Text)

Retrieves a substring from a comma-separated string.

Syntax


NewString := SELECTSTR(Number, CommaString)  

Parameters

Number
Type: Integer

Specifies which substring to retrieve. The substrings in the comma-separated string are numbered 1, 2, 3, and so on.

If Number is greater than the actual number of substrings, then a run-time error occurs.

CommaString
Type: Option

A string that contains substrings separated by commas. The maximum length of this string is 391 characters.

Property Value/Return Value

Type: Option

The substring that is retrieved from CommaString.

Remarks

SELECTSTR treats string values as OPTIONS. This means that identical values in different strings are not allowed.

Any trailing commas are removed before the operation starts.

If Number is less than 1 or greater than the number of real values (excluding trailing commas) in the string, then an error is returned.

Quotes are not supported. For example, a,b,"c,d",e is treated as a five-element substring where substring 4 is d".

Example

This example requires that you create the following variables and text constants in the C/AL Globals window.

Variable name DataType Length
CommaStr Text 60
CommaStr2 Text 60
SubStr1 Text 60
SubStr2 Text 60
SubStr3 Text 60
SubStr4 Text 60
Text constant ENU value
Text000 This,is a comma,separated,string
Text001 The calls to SELECTSTR return:\
Text002 11,22,33,,55,,,
CommaStr := Text000;  
CommaStr2 := Text002;  
SubStr1 := SELECTSTR(2, CommaStr); // Pick out the 2nd substring.  
SubStr2 := SELECTSTR(4, CommaStr); // Pick out the 4th substring.  
SubStr3 := SELECTSTR(1, CommaStr2);  
SubStr4 := SELECTSTR(3, CommaStr2);  
MESSAGE(Text001 + '>%1<\' + '>%2<\' + '>%3<\' + '>%4<\', SubStr1, SubStr2, SubStr3, SubStr4);  

The message window displays the following text:

The calls to SELECTSTR return:

>is a comma<

>string<

>11<

>33<

Example

This example requires that you create the following variables and text constants in the C/AL Globals window.

Variable name DataType Length
CommaStr2 Text 60
SubStr5 Text 60
Text constant ENU value
Text002 11,22,33,,55,,,
CommaStr2 := Text002;  
SubStr5 := SELECTSTR(6,CommaStr2);  
MESSAGE('>%1<\', SubStr5);  

This example returns an error.
