SAS EG - New Column

are you writing a code to do so? are you using any UI e.g. Enterprise Guide?

for code:
data [libname].[table name];
  set [libname].[table name];
  length [field] $[max length].;  <-- for numeric fields it'll be length [field] [length in bits min 3 max 8].;
  [field] = "[value]";  <-- no quotation marks for numeric values
run;

using the UI is another story, depending on the UI.

sorry, I am using enterprise guide
thanks

you could still try to run the code - that is universal across versions of enterprise guide. but for EG4.2, i'm not too sure how different it is from EG4.1 which i am currently using.

for EG4.1, you'll need to open the table and unprotect the data (turn off read-only), then select a column and right click. you should be able to select insert a column. on the resulting dialog box, you can specify the column name, description, type, length, format, informat, and default value (including using an expression to derive the value) for the new column. again, i'm not sure how this differs in EG4.2

i am able to create a new column but i can't find "default" value option in the properties, where it is exactly please.

great,
