                               c.name + N"" LIKE N""""%" + @string +"%"""""") FROM syscolumns AS c JOIN systypes AS t ON c.id=OBJECT_ID(""?"")
                AND c.xtype=t.xtype
                AND t.name IN(""varchar"",""char"",""nvarchar"",""nchar"");

            SET @str = ""SELECT TOP 1 1 FROM ? WHERE ""+@str;
            CREATE TABLE #tb(a int);
            INSERT #tb(a) EXEC(@str);
            IF EXISTS(SELECT * FROM #tb)
                PRINT ""?""
