.net - How to ensure dates are in correct format for OleDbCommand parameters? -

-

when execute code below against mdb database, data table empty, when run in query tool against database returns 2 records.

what problem?

is issue date format of parameters (ie. 8/5/13 vs 5/8/13)?

using odb oledbconnection = getdbconnection()     using ocmd new oledbcommand("select * " & _             " table1, table2" & _             " (table1.date between @date1 , @date2) , (table1.id null) , (table2.number = table1.num) , (table1.code1 = table2.code1) ", odb)         ocmd.parameters.addwithvalue("@date1", date.today)         ocmd.parameters.addwithvalue("@date2", date.today.adddays(me.intdaysahead))         odb.open()         dt = new datatable()         using da oledbdataadapter = new oledbdataadapter(ocmd)             da.fill(dt)         end using     end using end using

i think right. recommend specify parameter type oledbtype

 ocmd.parameters.add("@date1", oledb.oledbtype.date).value = date.today

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
