I am using QGIS version 2.14.1 (Essen) and trying to update data in my table using field calculator.

I am inputing the following statement:

update "table_1" 
set  "table_1" ='y' 
where  "table_2" ='test'

But I get the following error message:

syntax error, unexpected COLUMN_REF, expecting $end

Anyone know where i'm going wrong?

  • Are "table_1" and "table_2" from the same attribute table (same layer)? – Joseph Apr 27 '16 at 10:26
  • @Joseph yes they are from the same layer... – philippe Apr 27 '16 at 10:27

If you select "table_1" for the Update existing field option, try using this expression:

if( "table_2" = 'test', 'y', "table_1")

Basically, you're using an IF THEN ELSE statement.
