Hi all,

 

i am trying to implement the saveasasciiformatted function.

we need to export the contents of our datawindow to a ; separated file.

this works just fine, except for the decimals.

 

we would like to force the decimals to be exported as 9999999999.99999 where the . is the decimal separator.

We are located in Europe so our users are using the , comma as decimal separator.

So in the datawindow we "see" the value

 

123456789,12345  => this should be exported as 123456789.12345

1234 => this should be exported as 1234.00000

0,123 => this should be exported as 0.123

 

Bare in mind , i don't want to be reading and processing line by line, unless there's no alternative.

 

i found the dw_1.SetFormat() function which allows me to change the format just before the .saveasciiformattedtext function call.

 

Big question is now , to which format i must set my decimal columns to obtain what i want please ?

 

 

 

TIA

John

Hi John;

  FYI: The SaveAsXxxxx() commands in PB for the DWO just saves the current "Primary Buffer" data "as is". My suggestion would be to create another DWO for exporting. In the 2nd DWO, modify your SQL statement to extract the datum in the format you need for exporting using the appropriate DBMS conversion / formatting commands. That should return the numeric data in as a string data type - exactly as you require.

HTH

Hi John,

I have Danish regional settings (decimal comma, grouping dot, list separator semicolon).

PowerBuilder's standard functionality has regional settings woven into all conversion to/from strings incl. import/export of text files. So, you have to either

  1. Change regional settings temporarily (often forbidden for regular user due to security) - or -
  2. Transform to text using your own code.

As Chris suggests your SQL database may have more formatting options that require less code than doing the conversions in PowerScript.

CAUTION - Date, Time, and DateTime also depend on regional settings. Especially order of Day and Month varies by country. File exported by one user imported by another user may switch day/month in the date values. Test for it!

CAUTION - Sorting is also impacted. This is important if you use a "ZZZ" row to mark end-of-file. Danish example:

  • ("AA" <  "BB") evaluates to FALSE.
  • ("AA" >  "ZZ") evaluates to TRUE.

HTH /Michael

Hi John;

Have you tried the "TO_VARCHAR" Function?
