How to set numwidth in the grid output of PL/SQL developer?

I'm running some queries in PL/SQL Developer, and one of the columns in the result has 18-digit numbers. Instead of displaying the entire numb开发者_StackOverflower in the resulting grid, PL/SQL Developer displays only 15 digits in scientific notation.

I tried to find a way to change this in the preferences of the program, so that I'll see the entire number, just like set numwidth does in SQL*Plus. But my search was futile.

How do I change this setting?

Turns out this is possible!!!

Tools -> Preferences -> SQL Window -> Number fields to_char

Use to_char, then you get the all the numbers:

select to_char ( t.reference_nr), t.reference_nr from rss_ing_cc_imp t
1   95209140353000001009592 9,5209140353E22
2   25546980354901372045601 2,55469803549014E22

You can also set the column format(Using the same table name as above...)

column reference_nr format 99999999999999999999999999999999

Select reference_nr from rss_ing_cc_imp;

REFERENCE_NR

      95209140353000001009592 
      25546980354901372045601 

Or ( new session ) which probably is better:

show numwidth

numwidth 10

Select reference_nr from rss_ing_cc_imp;

REFERENCE_NR

 9.5E+22 
 2.6E+22 

Set numwidth 30

show numwidth

numwidth 30

Select reference_nr from rss_ing_cc_imp;

REFERENCE_NR

   95209140353000001009592 
   25546980354901372045601

SET sqlformat ansiconsole;

This will set the output format for any queries that you run hereafter. There are other sql formats but this is probably the best for your situation.

To revert to what you had earlier, use.

SET sqlformat;

*This has been verified on SQLDeveloper Version 18.3.0.277, Build 277.2354

Same answer as Ilya Kogan, but in PL SQL Dev 13 the Preferences has moved and is now under an little tuner icon in the title bar. Then SQL Window -> Number fields to_char
