Hi,
how can i convert a varchar field to a text field?
I try with

alter table doc_valor modify sustituto text;

but it doesn't work .....
[Error] Script lines: 1-1 --------------------------
Illegal attempt to convert Text/Byte blob type. 

Hi,

I suggest that run unload table to file plane, and load to other new table with new format.
Or alter table of VARCHAR to CHAR

Gustavo.
