DataTable.Select With ' (single Quote) Character In The Query?

Oct 19, 2011

I 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'")

SqlCommand Parameter / Replace A Single Quote With Two Single Quotes

Oct 23, 2009

I 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):

DB/Reporting :: Single Character With In A String Search In SQL Query?

Jan 14, 2011

I am trying to do a SQL query that checks for the presence or absence of a character's occurance in a field / column as a condition to retrieve the row. In this case I only need to test for existance of the specified character and in a similar query to test for the non existence. Not where it is or how many, just is it there or is it notI am using VB express.net 2008 and it uses, I think, MS SQL Server 2008.Using VB's instr() I can tell straight away if a string does or doesn't contain a character, but I would like to know this before I retrieve the row.

using the

WHERE .... and [mytable.myfield] LIKE 'Q'
or
WHERE .... and [mytable.myfield] NOT LIKE 'Q'

produces a result, but not a correct result. It does something but I can not say that it is working even part way.CHARINDEX gets an undefined function error MATCHES also gets an undefined function error?CONTAINS looks like it should work but I am still getting sytax errors with it, so I don't know how to use that predicate yet.

Select Query From One Datatable To Another

Nov 20, 2011

I have pulled information from a database into a datatable (dtCustomerInfo) then I expanded on the columns by processing the data and I can display this in a datagridview without any problem. However, the data is in detail and I want to ultimately summarize by customer name.The code below has a commented sql statement that is the statement I ultimately want but it is not working. However, the idea is that I want to Select from one datatable into another but run aggregate sum on several columns so that I will get one record per customer showing totals for each column.So I broke it down to just pull all data possible into the second table.[code]I do know the grouping in the current select * statement does nothing but my issue is more that the columns do not show up.

SQL Server 2005 - Select From Multiple DB's & Compile Results As Single Query?

Sep 25, 2009

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.

Specify A Custom Select Query For A Datatable Fill Method?

Dec 17, 2009

VB.Net 2005 SQL server 2005

I have a project I have a dataset that contains tables In the dataset designer, each table has a defaiult FILL command set. I have draged and droped my table as a grid onto my form VB automatically sets up the table adapter, and binding source to make it all work.

in my code, is placed in the form load routine, a tableadapter.fill(dataset.datatable)

Here is my dilemma. The data in my table may have 100's of thousands or rows.

I have presented the user with a front end that allows for filterring and selecting based on several columns. reguardless of how many rows the result set contains, there will always be the same columns in the dataset.

Because there are so many combinations of select query, i do not want to make 20 or 30 custom fillby's in the dataset. I want to make an addhoc select query and have the binding source and table adapters work as expected. I have created a query called "FillByCustom" in the dataset designer attached to the DataTable Adapter section.

My question is this.

If i build a select query that returns the desired rows, how do i place it into the adapter in place of the FILLBYCUSTOM select command, such that it all works as expected?

.net - Sql Parameters Appear To Not Add In The Single Quote For Strings

Oct 4, 2011

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.

How To Escape Single Quote In String.Format

Jun 24, 2010

While 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.

Asp.net - Single Quote In LINQ Results Causing Error

Jul 14, 2011

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

Convert Text With Single Quote To Upload To Oralce DB?

May 14, 2012

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()

Treat Unicode Character Plus Diacritic As A Single Character?

Aug 23, 2010

In my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.
