SQL Select And Logical OR

May 21, 2008

I have a query. on my search page i have a number of textboxes e.g. title, subtitle, ISBN where users can enter a search string and when they click on a button the data is displayed in the gridview below.
my query seems to be bringing up the right records but with some additional records into the gridview. I have tried the same query within the SQL server management studio and it brings back two records like indicated but within my aspx page it brings back 6 additional records that have no relevance to the query. Im quite baffled as to why this is happening and i have debugged but nothing comes to light.
my code in my aspx page is as follows:
public void BindData(){String _BookID = TxtBookID.Text;String _Title = TxtTitle.Text;String _Subtitle = TxtSubtitle.Text;String _ISBN = TxtISBN.Text;String AuthorFName = TxtForename.Text;String AuthorLName = TxtSurname.Text;
SqlDataAdapter ad = new SqlDataAdapter("SELECT Book_ID, Book_ID_Internal AS [Book Internal ID], Title, Subtitle, ISBN, Edition, Publication_Date AS [Published Date] FROM Book WHERE Book_ID_Internal = '" + _BookID + "' OR Title = '" + _Title + "' OR Subtitle = '" + _Subtitle + "'", conn);DataSet ds = new DataSet();ad.Fill(ds, "Book");if (ds.Tables[0].Rows.Count == 0){//if there are no rows returned-state in the gridds.Tables[0].Rows.Add(ds.Tables[0].NewRow());GridView1.DataSource = ds;GridView1.DataBind();int columncount = GridView1.Rows[0].Cells.Count;GridView1.Rows[0].Cells.Clear();GridView1.Rows[0].Cells.Add(new TableCell());GridView1.Rows[0].Cells[0].ColumnSpan = columncount;GridView1.Rows[0].Cells[0].Font.Italic = true;GridView1.Rows[0].Cells[0].Text = "No Records Found";}else{GridView1.DataSource = ds;GridView1.DataBind();}}
if i input the same query into SQL management studio:
SELECT * FROM Book WHERE Book_ID_Internal = 'ITD 450' OR Title = 'HTML 4.0'
it returns two records which is correct.
Can anyone see where i am going wrong?

Attempting To Select A Range Of Values Using Wildcard And Between Or Logical Operators?

Mar 16, 2014

I am in the midst of writing a query to return a range of product BIN LOCATIONS from a warehouse stock levels program.I know the start and end BIN LOCATIONS for the warehouse, e.g.: Start - #00000, and End - Z10000.However I cannot hard code these into the program, instead I want my operator to designate the first letter of both the start and end BINS locations, and then hit the 'go button'.Towards this end I have declared a couple of variables in my SQL, as follows -

Code:
declare @strBin varchar(10)
set @strBin = ''
if @strBin = ''
set @strBin = '#%'

declare @endBin varchar(10)
if @endBin = ''
set @endBin = 'z%'

My challenge is writing a relevant WHERE clause for my select statement, I have tried the following -

Code:
where BINLOCAT.BINLABEL between @strBin and @endBin
order by BINLOCAT.BINLABEL

Whilst the clause above does not cause any errors, neither does it return any results.My first thought is that the BETWEEN operator does not accept wildcards. But if this is correct then how do I go about allowing an operator to enter the start, and end BINS without typing the entire BIN string (e.g.: #00000)? I have tried >= @strBin and <= @endBin, but I am having a similar issue with no errors, and no data returned.
