[GRASSLIST:3782] Fun with dbf in GRASS57

[SWlab]

Hello,
I want to select some areas from a vector map connected to a dbf file. The 
wanted area must match a given string pattern, but I can't get passed this 
message:

DBMI-DBF driver error:
SQL parser error in statement:
SELECT * FROM NHD_HU11d WHERE HUC_11 LIKE '02040101%'

Could anybody point me to some generic references about what a dbf server can 
or cannot do, and how easy is it to switch to another driver (seems that I'll 
have to use postgresql eventually...)
Thanks an awful lot in advance
