Max length of all fields in the Dashboard

Hi All,

I have a requirement to display the list of all the field names and its maximum value length.

I have tried max(len($Field)) in front end which gives me length of the field name not the value.

I have tried loops in script tried max(len(FieldName(Field,Table)) , again it gave length of the field name not the value..

Please suggest a solution.. Front end or in script any thing is fine

My desired o/p is

 

Table NAmeField NameMaxlength
Table1Field122
Table1Field210
Table2Field1121
Table2Field223
Table2Field334
Table3Field120

Hi,

one solution on load Script :

Suppose I have those Tables :

Taoufiq_ZARRA_0-1592924675095.png

 

The Script :

Table1:
load * inline [
A,B,C
1,2564,56464 dfgs
10,25,56464 dfgssd
];


Table2:
load * inline [
AA,BB,CC
1sdfd,25sdfs64,56fdsfds464 dfgs
1fsdf,2ff5,56dfsdffsdfsdfd464 dfgssd
];


FOR i = NoOfTables()-1 to 0 STEP -1

  LET vTable=TableName($(i));
  
  
  FOR j =1 to  NoOfFields('$(vTable)')
 
FieldMax:
  let vFieldName=FieldName($(j),'$(vTable)') ;
 //let vfakue=Peek($(vname),'$(vTable)');

   
   LOAD 
   
     len($(vFieldName)) as lengthfield,
   '$(vTable)' as [Table Name],
   '$(vFieldName)' as [Field Name]
   
    RESIDENT [$(vTable)];
  
  NEXT j
   

NEXT i


outputFieldMax:
noconcatenate
load [Table Name],[Field Name], max(lengthfield) as Maxlength resident FieldMax group by [Table Name],[Field Name] ;

drop table FieldMax;

 

The output :

hi,

Find the Max length of the fields in each table while load itself and sort by Descending order. 

Do the Resident load where rowno=1 and concatenate as single table and present in the dashboard.

Yogesh.

Yes This is working. Thanks..

 

But it loads all the columns again.. like if there are 200 columns in the dashboard. It loads all the columns again.. I am using this solution as of now. But please let me know if something can be done in a optimized way either in front end or scripting

10,25,56464 dfgssd
];


Table2:
load * inline [
AA,BB,CC
1sdfd,25sdfs64,56fdsfds464 dfgs
1fsdf,2ff5,56dfsdffsdfsdfd464 dfgssd
];


FOR i = NoOfTables()-1 to 0 STEP -1

  LET vTable=TableName($(i));
  
  
  FOR j =1 to  NoOfFields('$(vTable)')
 
FieldMax:
  let vFieldName=FieldName($(j),'$(vTable)') ;
 //let vfakue=Peek($(vname),'$(vTable)');

   
   LOAD 
   
     Max(len($(vFieldName))) as lengthfield,
   '$(vTable)' as [Table Name],
   '$(vFieldName)' as [Field Name]
   
    RESIDENT [$(vTable)];

A UI solution would be a tricky one but possible.

 

$(=concat('if($Field=' & chr(39) & $Field & chr(39) & ',Max({1}Len([' & $Field & ']))', ',') & concat(right($Field&')',1)))
