View 3 RepliesI have a string like "Hello'World" and a Data Table with some records in it. One of those records is "Hello'World".he problem is, when I do a .Select in the Data Table, it only tries to search for the "Hello" part and throws an error on "World" because it interprets the ' (single. cuote) like the closing cuote on sql.DataTable.select("text = 'Hello'World'")I have gone through msdn doc, and it says I can escape some characters with [] brackets or f.slashes , but I just can't figure out: .select("text = 'Hello[']world'")
View 1 RepliesI use SqlParameters when executing database statements. I know that I can replace a single quote with two single quotes... but in the past SqlParameters took care of this for me. I have two projects.. in one, the SqlParameter does this and it handles single quotes fine, in another, it does not and I'm at a loss why (I even copied and pasted the code):

I have this block of code that sets up my sql parameters for a stored proc that does an insert.
Dim sproc As StoredProcedure = New StoredProcedure("UsersInsert2", DataAccessConfiguration)
sproc.AddInput("@ID", SqlDbType.NVarChar, 10, entity.UserId)
sproc.AddInput("@PCode", SqlDbType.SmallInt, entity.PriviledgeCode)
sproc.AddInput("@Pwd", SqlDbType.NVarChar, 10, entity.Password.ToString())
[code]...
I've tested the stored proc in SSMS and it works.The problem is when I try to call it from the application. it fails. the @@rowcount = -1. I've tried returning an error code from the db... no dice. keeps coming back as -1 what is going to get executed looks like this
sproc = {EXEC UsersInsert2 @ID=ruxtest7, @PCode=0, @Pwd=1234, @Lang=E, @Name=ruxpint, @Notice=1, @CreatedBy=ruxpint}
I've re-used this code several times. only difference being I'm using NVarChar and it's vb.net.
It would seem to be Dim MyString as String = """""" but VB doesn't like that.
View 2 RepliesWhile searching on how to escape a single quote in String.Format, I found the answer at SO: Escaping single quote in String.Format(). It seems to be different for VB though. I tested it, and indeed C# needs
string s = DateTime.Now.ToString("MMM d \'yy 'at' H:mmm");
while VB needs
Dim s As String = Now.ToString("MMM d 'yy 'at' H:mmm")
Why does C# need a double backslash, and VB a single backslash? This might be a bit of a silly question to C# users, but while I can read C#, I'm not used to writing it.
I am having an issue with the following code. It works when the data is all numeric such as 9200000 but not when the data is alpah numeric such as b101462 I am collecting data from a textbox into a string variable findacct and then using the variable in the sql statement. The data in the access database is char type.
The following select statement works when all the data is numeric for the find acct varialbe but if start with a alpha char like B101462 it gives me a missing parameter error."Select * From purchase where issuedate >= " & "#" & finddate & "#" & "and account like " & findacct)The following statement works when I actually put the account info in the select statement and do not use a variable."Select * From purchase where issuedate >= " & "#" & finddate & "#" & "and account like 'b101462'")
I use in my Project the IfExistsTable function; in order to see the existence of a table.
For this purpose I use the Select statement as follows.
MASQLComm = New SqlCommand("SELECT COUNT(*) AS [RecCount] From sys.tables WHERE name Like '%" & tName & "%'", SQLConn)
RecCount = CInt(MASQLComm.ExecuteScalar)
After that I take the number which returned in RecCount. Until now the numbers was 1 and 0
And so I was turn the numbers in True or False.Now suddenly the returned number is 2 which I can't understand what it means.
I have the following LINQ query:
Dim find_id = From p In dbContext.Residents _
Where p.person_name = occupant _
Select p
I then pull the first returned ID like so:
Dim building_id As String = find_building_id.FirstOrDefault.id
This works fine, except with the person has a ' in their last name, like M'arta. In this case I get a NullReferenceException.
Okay, the problem appears to be that when I am capturing the name initially from a GridView it is inserting into the value a #39 instead of ' and then LINQ is keeping things correct, so I end up with a non-match since it is attempting to match:
M#38arta = M'arta
I have a function in VB.NET that runs a query from an MS SQL DB, puts the results into temporary variables, then updates an Oracle DB. My question is, if the string in the MS SQL contains a single quote ( ' ), how do I update the Oracle DB for something that has that single quote?
For example: Jim's request Will produce the following error: ORA-01756: quoted string not properly terminated The ueio_tmpALM_Comments (coming from MS SQL) is the culprit that may or may not contain the single quote.
update_oracle =
"update Schema.Table set ISSUE_ADDED_TO_ALM = '1'," & _
"ISSUE_COMMENTS = '" & ueio_tmpALM_Comments & "'," & _
"where ISSUE_SUMMARY = '" & ueio_tmpALM_Summary & "' "
Dim or_cmd_2 = New NetOracle.OracleCommand(update_oracle, OracleConn)
or_cmd_2.ExecuteNonQuery()

I have a listview box. I load the listview up from a text file and everything is divided into three groups. I need to be able to select multiple lines then push that out to a single variable, separated by commas. Two things are happening that are problematic:
1) If I just have it set to smallicons and no checkboxes, anything I select is highlighted right up until the control loses focus at which point everything un-selects.
2) If I turn on checkboxes, I can click boxes and they stay selected when I lose focus BUT the checkboxes are cut off on the left side of the control. (The checkbox appears to go off the edge of the control.) There's plenty of space in the control for the checkbox and the listed items.
Ok, the basic situation: Due to a few mixed up starts, a project ends up with not one, but three separate databases, each containing a portion of the overall project data. All three databases are the same, it's just that, say 10% of the project was run into the first, then a new DB was made due to a code update and 15% of the project was run into the new one, then another code change required another new database for the rest of the project. Again, the pertinent tables are all exactly the same across all three databases.
Now, assume I wanted to take all three of those databases - bearing in mind that they can't just be compiled into a single databases due to Primary Key issues and so on - and run a single query that would look through all three of them, select a given set of data from each, then compile those three sets into one single result and return it to the reporting page I'm working on.

A company pays its salespeople on a commission basis. The salespeople receive $200 per week, plus 9% of their gross sales for that week. For example, a salesperson who grosses $5000 in sales in a week receives $200 plus 9% of $5000, or a total of $650. Develop a console program (using a one-dimensional array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assume that each salesperson?s salary is truncated to an integer amount):
a)$200-$299
$300-$399
c)$400-$499

My gross salary formula works fine but im confused about my For Next Statement. Not sure if im doing it right. i forgot one thing.... i'm not sure if my increment counter should be where i put it. I think it needs to be in my for next statement?
