Hi Folks, I have a serious problem. must create a regular expression against all that is between single quote or double quotes. Easy? Ok, i know, but i need that "everything" must to be too an single quote or double quote. If i have this SQL command: SELECT * FROM TSTRENIC.MEI_ACESSO WHERE UPPER(DS_MEI_ACS) LIKE *'%NOME' ASD ' AS'ASD'%' *AND USUARIO = *'oaksdpokasd'asda'* ORDER BY DS_MEI_ACS ASC; SELECT * FROM TSTRENIC.MEI_ACESSO WHERE USUARIO_DATA BETWEEN *'2007-01-02'*AND *'2008-07-08'* Anyone have any idea? I need an expression which case the fields in bold. Regards, Igor Escobar Systems Analyst & Interface Designer + http://blog.igorescobar.com + http://www.igorescobar.com + @igorescobar (twitter)
