Делай так:

Код:

ADOQuery1.SQL.Add('SELECT SS,SN_POL,FAM,IM,OT,W,DR,SN_DOC,C_DOC,ADRES,OKATO_ REG,S_EDV,DB_EDV,DE_EDV,C_KAT1,C_KAT2,DATE_RSB,DAT E_RSE,U_TYPE,DATA FROM [REG_LGOT].[dbo].[r2007] as t WHERE t.SS='+QuotedStr(MaskEdit3.Text));

или так:

Код:

ADOQuery1.SQL.Add('SELECT SS,SN_POL,FAM,IM,OT,W,DR,SN_DOC,C_DOC,ADRES,OKATO_ REG,S_EDV,DB_EDV,DE_EDV,C_KAT1,C_KAT2,DATE_RSB,DAT E_RSE,U_TYPE,DATA FROM [REG_LGOT].[dbo].[r2007] as t WHERE t.SS= :a');
ADOQuery1.Parameters.ParseSQL(ADOQuery1.SQL.Text,true);
ADOQuery1.Parameters.ParamByName('a').Value:=MaskEdit3.Text;
