INSERT statement in JSP using variables

People,
I am having problems inserting data from JSP into a MySQL database.
For example the following works perfectly fine:
String query = "INSERT INTO `test2` (`name`, `topic`, `message`) VALUES ('Jane Doe', 'Hi there', 'Example message')";
But, however the problems take place if I try to use variable values as parameters instead of pre-defined strings.
E.g. the following (among a 100 other ways I have tried by now) does not work):
String query = "INSERT INTO `test2` (`name`) VALUES (`" + userName +"`)";
stmt.executeUpdate(query);
This did not work either:
PreparedStatement PStmt = myConn.prepareStatement("insert into (`name`) values (?)");
PStmt.setString(1, new String("`" + userName + "`"));
PStmt.executeUpdate();
I have tried without parenthesis etc. but what I pretty much get every time is:
500 Servlet Exception
java.sql.SQLException: Column not found: Unknown column 'Jane' in 'field
list'

I do not know much about SQL or JDBC but the material I have seen makes me believe
that I am pretty much doing the right thing.
What is the right way of doing this?
I would greatly appreciate any feedback.

Hi,
I think i know the problem.
Take a look on your String code :
"INSERT INTO `test2` (`name`, `topic`, `message`) VALUES ('Jane Doe', 'Hi there', 'Example message')";
it is not necessary to put QUOTE for the tablename and the fields.
my code work with :
String query = "INSERT INTO test2 VALUES( ' " + 123 + " ' ) ";
( if you inserting into all fields in your table ) OR
String query = "INSERT INTO test2 ( abc ) VALUES( ' " + 123+ " ' ) ";
( if you need to select certain fields ).
or you can try to refer to :

hope this help.

INSERT statement with JSP

          Does anyone know how to create an INSERT statement with JSP using
          variables??
          I can do the insert if I code the values of the variables in the statement,
          but when I try to use variables to do the insert it tries to insert the
          variable name and not the value of the variable into the table.
          Thanks,
          Doug

the insert statement looks right to me but there is something wrong anyone got any ideas. Thanxs in advance.

AAAHHHH. Order is a reserved word and that was what my table was named. I suppose because of the order by clause it is. Figures spend hours staring at it and it is right there. I have to start using prefixes and suffixes on my code it would save me so much hassel.

Insert applet in jsp using plugin

Hi,
the codebase reference causes the problem because in Java "\" is an escape indicator. Also, the code sample doesn't work unless you wrap the jsp:plugin tag in a <f:verbatim></f:verbatim> cosntruct

Using System::ErrorDescription in Insert statement

Hello,
I want to insert System::ErrorDescription to store the error in the customized log table. When I use the following statement, it does not insert anything. What am i doing wrong. Please advice.
create table dbo.load_err(load_err_id integer(PK),load_err_Dtl,loadtime)
INSERT INTO dbo.LOAD_ERR (LOAD_ERR_ID,
LOAD_ERR_DTL,
loadtime)
VALUES (NEXT VALUE FOR dbo.LOAD_ERR_SEQ,
@[System::ErrorDescription] ,
getdate())
I see the row inserted but nothing in the Load_ERR_DTL column.

Where are you using the insert statement? The ErrorDescription variable is only available inside OnError,OnWarning and OnInformation event handlers
http://msdn.microsoft.com/en-IN/library/ms141788.aspx
Also you need to use insert statement as below
INSERT INTO dbo.LOAD_ERR (LOAD_ERR_ID,
LOAD_ERR_DTL,
loadtime)
VALUES (NEXT VALUE FOR dbo.LOAD_ERR_SEQ,
getdate())
and map parameter0 to @[System::ErrorDescription] in parameters tab
another way is to set SQLSourceType
as Variable and set a variable for the query with below expression as
"INSERT INTO dbo.LOAD_ERR (LOAD_ERR_ID,
LOAD_ERR_DTL,
loadtime)
VALUES (NEXT VALUE FOR dbo.LOAD_ERR_SEQ,'" +
@[System::ErrorDescription] + "',
getdate())"

INSERT Statement behind a FORM on a TABLE with REPORT

When I create a form on a table with report, I'm sure an INSERT STATEMENT is genereated in the background somewhere. How can I see this insert statement or how can I get to this INSERT statement? If I can see it, would I be able to modify this INSERT statement?
Please use simple terms.
Thanks.

Roel
At first, i was just curious to see where that insert statement is and how it looks like.
Later, I really wanted to see it because I wanted to know how it looks like whne I try to insert a one to many relationship record. Don't know if I'm being too clear on this.
Lets say table A and B have a 1-to-many relationship. When I want to insert records into both A and B, how does the insert work? Maybe if I get an answer to this question, I may understand how the inserts are done on a 1 to many relationship data insert.
Thanks.

Using sql:variable in an insert statement

I'm writing an insert statement for a table with an XML column. Most of the XML is static, but I need to replace the value of an element with the value of a T-SQL variable, as shown here:
CREATE TABLE [dbo].[OrderDetail](
[OrderID] [int] NULL,
[OrderDetail] [xml] NULL
GO
DECLARE @XMLData XML;
DECLARE @ItemID INT;
SET @ItemID = 1000;
SELECT @XMLData = N'
<OrderDetail xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
</OrderDetail>
SET @XMLData.modify('insert <ItemID>[sql:variable("@ItemID")]</ItemID> into (/OrderDetail)[1]')
INSERT INTO [dbo].[OrderDetail] ([OrderID], [OrderDetail])
VALUES (@ItemID, @XMLData);
When I run this, it inserts "[sql:variable("@ItemID")]" instead of the value of @ItemID. If someone could show me the proper syntax, I would really appreciate it. Thanks.

Yes, that worked. Now I want to change it a little. I also have an attribute that I need to update with the value of a variable.
DECLARE @XMLData XML;
DECLARE @SetID INT;
DECLARE @SetIDStr VARCHAR(12);
DECLARE @SetIDXML XML;
SET @SetID = 9999;
SET @SetIDStr = CONVERT(VARCHAR(12), @SetID);
SET @SetIDXML = CONVERT(XML, @SetIDStr);
SELECT @XMLData = N'
<OrderDetail xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ItemID>1000</ItemID>
<RightOperand ID="15524" Name="ItemName" Value="15524" />
</OrderDetail>
SET @XMLData.modify('replace value of (/OrderDetail/RightOperand/@ID)[1] with sql:variable("@SetIDXML")');
INSERT INTO [dbo].[OrderDetail] ([OrderID], [OrderDetail])
VALUES (@SetID, @XMLData);
SELECT * FROM [dbo].[OrderDetail];
I'm trying to replace "ID="15524"" with the value of @SetID. This code throws an exception:
Msg 9342, Level 16, State 1, Line 23
XQuery [modify()]: An XML instance is only supported as the direct source of an insert using sql:column/sql:variable.
Thanks again for your help.

Using variables to insert data in the table

I want to insert datas in the table. I use constants,
all the constants are stored properly in the table. But,
when I use variables I get the error message
"Too few parameters. expected 6".
(I declared all the fields of the table as text only.)

Those who know answer please reply.
My thanks in advance.

I would expect your insert statement to be this:
statement1.executeUpdate("insert into cust1 (cno,n,add1,add2,phone,email) values('"+cno1+"','"+n1+"','"+add11+"','"+add21+"','"+phone1+"','"+email1+"')");
If you just create a string, it's not going to fill in variables into the string by magic.

Using the Insert statement in a Java program without hardcoding the data

hello.
this is james mcfadden. i have developed a program called Demo.java, which is used with another program called QueryTableModel.java (a program that allows data to be viewed in a JTable). The Demo.java program displays a menu, connects to a database, allows the user to add data into the database and allows the user to view data that is already in the database. I have a problem with the Demo.java program. I have hardcoded the Insert statement in it. How do you use the Insert statement to put data into a database without hardcoding the data?

Use NEXTVAL in an insert statement Part II

db - 10g
I am asking this question out of curiosity.
I posted a question and recieved a successful answer at the following address on this forum;
Use NEXTVAL in an insert statement
The following insert statement uses a sequence to create an arbitrary number for each null record. The problem is, the sequence is firing regardless of the condition being true or false (but it is working in that it only inserts values when the condition is true). The result is the sequence appears to increment each time it loops through the cursor and so the first arbitrary number to be inserted is not 1001 but some other higher number.
INSERT INTO psp_trees
( plot_id
, tree_name
, species_code)
VALUES
( get_plot_id
, c1.treenum
, c1.species
) RETURNING tree_id INTO get_tree_id;   I have gotten around the issue by removing the sequence from the insert statement and placing it outside the cursor loop as an update statement.
      UPDATE psp_trees
         SET tree_name = to_char(tree_arbitrary_name_seq.nextval)
       WHERE tree_name IS NULL;Is there anyway to get the sequence to only fire in the insert statement when the condition is true.

Inserting your own sql-statements in JSP

How do I use my own sql-statements in JSP combined with the ones
generated by JDeveloper?
It seems to me that the following sentences are the ones
generating the sql for inserting in a database:
<jbo:DataSource id="ds" appid="MimPKG.MimPKGModule"
viewobject="BidragView"/>
<jbo:Row id="newRow" datasource="ds" action="Create">
<jbo:SetAttribute dataitem="*"/>
</jbo:Row>
I would like to have more control and therefore I need to make
my own sql-statements.
Is that possible?
Thanks
Leise

You can use ExecuteSQL data tag to do so. It allows you to
include your own query like insert, update etc.

How to assign bean value to a local variable in JSP using struts.

Hi everybody!
I've a problem that puzzled me on how to assign a bean value to a local variable like String in JSP using struts.
we can have someting like this to display the value
<bean:write name="detailService" property="status" />or
<bean:define id="theStatus" name="detailService" property="status"/>
This is country: <%=theStatus%>but an error occured when I tried like this:
String currentStatus = "<bean:define id="theStatus" name="detailService" property="status"/>";
or
String currentStatus = "<bean:write name="detailService" property="status" />";Is there a way to do this?.....
Any help pretty much appreciated

Java != JSP.
The <bean:define> and <bean:write> tags are custom tags meant to appear in the HTML section of a JSP file, as opposed to the scriptlet section. They actually get turned into java code as part of the translation process.
The <bean:write> tag naturally just writes out what you tell it to.
The <bean:define> tag defines a local variable, and gives it a value.
this should do it.
<bean:define id="theStatus" name="detailService" property="status" type="java.lang.String"/>
<%
String currentStatus = theStatus;
%>With the advent of JSTL, you shouldn't really need to use scriptlet code anymore. Personally I am for 0% scriptlet code in any jsp I write.

Using sqlerrm in insert statement in 10g

Hi,
I do not have 10g to test the following snippet, which tries to use sqlerrm in an insert statement:

declare
n_tmp   tbl.x%type;

exception
when others then
    -- the line below works in 9i
    -- dbms_output.put_line('Sqlerrm: '||sqlerrm);
    -- but the insert statement doesn't work in 9i, how about 10g ?
    insert into err(a,b) values (1,sqlerrm);
    commit;
end;

Use of case in an insert statement...

Hi ,
i have an insert statement in a db packaged procedure which needs a case statement to be used.....
I want to use the case in a statement like the following...
insert into x(a,b,c,d,e)
values(a,b,case b='1' then c_val , d_val , null else null , null , e_val);
In other words when the b_value (b column) has value '1' (in the example above) then the values for c , d columns of the tables are those passed as parameters to the procedure . On the other hand , when the the b_value (b column) has not value '1' then the values for c , d columns of the tables should be null and the on the e column another value passed as parameter to the procedure....????
Is the above general syntax of insert correct...????
Many thanks,
Simon

Something like this could do the trick:
insert into x
            (a, b, c, d, e)
     values (a,
             b,
             case
                when b = '1'
                   then c_val
             end,
             case
                when b = '1'
                   then d_val
             end,
             case
                when b = '1'
                   then null
                else e_val
             end
            );
