VB.net SQL data reader needs tweaking -


i have issue whereby 'using' sql query returning result where, if access db directly doesn't

here's code datareader

    using cmdobj new sqlclient.sqlcommand("select name dbo.cases case_reference = 'ab-" & textbox_case_ref.text & "-" & combobox_ref_year.selecteditem & "'", sqlconn)         using readerobj sqlclient.sqldatareader = cmdobj.executereader             while readerobj.read                 lima_op_name = readerobj("name").tostring             end while         end using     end using

things have ony got complicated since changed our case reference 'ab-#####-yy' #######

the problem that, long case reference exists, resulting 'name' returned correctly, case reference doesn't exist, seems return name of highest numbered case anyway!

if run same query in sql management, returns empty cell...

i alreasdy have 'if name = "", error' type line, isn't working query 'is' returning name - shouldn't doing. need better error correction in there?

additionally, can assist, want pad out entry in 'textbox_case_ref' 5 digits '0's user can type 1, 2, 3, , turn 00001, 00002, 00003?

thanks

richard
