Update statement in sql

I want to update table xx whose column is yy
where column value is successful it should be updated with successfully recharged
where column value is failure it should be updated with permanently failed
Can both of these updates are possible in a single update statment
I am able to use
update xx set yy='Successfully Recharged' where yy='Successful' --for a single statement
Thanks,

You may also use DECODE like:
UPDATE xx
   SET yy =
          DECODE (yy,
                  'successful', 'successfully recharged',
                  'failure', 'permanently failed')
WHERE yy IN ('successful', 'failure')The where clause is mentioned if there were more values in yy column and we don't want to update those records.

Update statement causes sql server to hang.....

Hello fellow java developers!
The goal that I have is the following:
1. Get a list of all entries in the database
2. Prompt the user for a user action
3. Upon user action, update the record in the database and goto #2... until dataset completed
I have done this successfully with an odbc connection to an access database, however access does not suit my needs.
What I have is a single open resultset rs1 - that contains all of the database entries.
Then I prompt the user for input based on a row of data
I then, open a new connection object, and a new statement object in order to update the database with the value
it hangs infinitely when it hits the "executUpdate" line in the code. I have try-catches all around it but no go....
any ideas?
below is my update code, it hangs on the executeUpdate line....
try {
//connect to database
String URL = "jdbc:odbc:" + m_strODBC;
Connection theConn3 = DriverManager.getConnection(URL, "", "");
Statement stmt3 = theConn3.createStatement();
//stmt3.setQueryTimeout(3);
stmt3.executeUpdate("Update " + m_strTableName + " set myVal=1 where Num=" + m_strMessageNum);
stmt3.close();
theConn3.close();
} catch (SQLException ex) {
ex.printStackTrace();
}

I know that this is a dumb question, but how do I properly use the ms jdbc driver? I mean I linked it to my code, but what do I need to change in order to use it?Well you need to download it and put it in your classpath. Then you need to load it with Class.forName and use the correct URL for connecting. You should consult the driver documentation for the correct names to use for Class.forName and URLs.

Hi Kevin,
According to the code you have posted, it looks like you are missing a space between "SET" and "last_name". I suggest you add the following line of code:
System.out.println(sql);
before the invocation of "executeUpdate()".
I also suggest you add the following line of code:
e.printStackTrace();in your "catch" block.
Hope this helps.
Good Luck,
Avi.

How to use a update statement which has a string containing '&' - Pls help

Copy records of one table into another using Update statement

Supposing I have 2 tables test and test1.
Test has columns col1 and col2. and test1 has only one table col1.
select * from test returns:
COL1 COL2
a
b
c
d
e
select * from test1 returns
COL1
p
q
r
s
t
Suppose i want to copy values of test1.col1 to test.col2 so tht final result of
select * from test should be
COL1 COL2
a p
b q
c r
d s
e t
I found a query in the OCP introduction book:
update test set col2=(select col1 from test11)
this works fine only when we have a single record in test1 table but fails otherwise.
how can this be achieved using the update statement ?

This will work only if you have the same number of lines in COL1 in both tables. If you have different number of lines, then you need to code more at join (outer, inner).
But for complicated cases, please post sample data.
Michael
PS: And supossing that the values are distinct in TEST table. Else update will fail, because more rows will be retrived.
If more values in TEST table in COL1, then you need to assign a row number on TEST also, and in WHERE of query you need to place one more join condition:
something like:
8* ) z where z.col1 = test.col1
and z.rn = test.rn)

But as i said, get more specifications.

Update statement with CASE and banding

Hello Folks,
I am stuck and am going nowhere.
I have two tables
MinuteCategory
Minute
MinuteCategory
MinuteLookup
MinuteCategoryId (surrogate key)
MinuteLow
MinuteHigh
MinuteCategory
Sample from Minute Lookup table ..
1 1
15 <15 min
2 16
30 <30 min
3 31
45 <45 min
4 46
60 <60 minutes
5 61
75 <1 hour 15 minutes
I am trying to update the MinuteCategory column in the MinuteCategory table using the MinuteLookup table.
For example if the minute = 33 then the corresponding lookup value would be 3 (from the lookup table), because the
33rd minute falls in between 31 min and 45 min and the corresponding surrogate key is 3
Is this possible with an Update statement in SQL? The only thing i can think of is use case statement as the join key between
the two tables but i don't think it's going to work :(
UPDATE
SET MinuteCategory = ml.MinuteCategoryId
FROM MinuteCategory mc join MinuteLookup ml on mc.Minute =
CASE WHEN mc.Minute between ml.MinuteLow and ml.MinuteHigh THEN ml.MinuteCategoryId ELSE NULL
END
Would appreciate any help.

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> I have two tables <<
Have you read any book on data, so you have some idea what a “<something>_category” means? THINK!! A minute is unit of temporal measurement. By definition, it cannot be a category.
There is no such thing as a “<something>_category_id”; a data element is a “<something>_category” or a “<something>_id”, as per basic data modeling.
Use a table of time slots set to one more decimal second of precision than your data. You can now use temporal math to add it to a DATE to TIME(1) get a full DATETIME2(0). Here is the basic skeleton.
CREATE TABLE Timeslots
(slot_start_time TIME(1) NOT NULL PRIMARY KEY,
slot_end_time TIME(1) NOT NULL,
CHECK (start_time < end_time));
INSERT INTO Timeslots --15 min intervals
VALUES ('00:00:00.0', '00:14:59.9'),
('00:15:00.0', '00:29:59.9'),
('00:30:00.0', '00:44:59.9'),
('00:45:00.0', '01:00:59.9'),
('23:45:00.0', '23:59:59.9');
Here is the basic query for rounding down to a time slot.
SELECT CAST (@in_timestamp AS DATE), T.start_time
FROM Timeslots AS T
WHERE CAST (@in_timestamp AS TIME)
BETWEEN T.slot_start_time
AND T.slot_end_time;

Use of ROWID in SQL Update Statement

Hi All,
I have an update statement which uses the rowid column to perform the selection on the target table. Given that a rowid represents the physical location of a row on disk we know that this reference can change when various activities are performed on the database/table/row etc...
Here is an example of the statement I am issuing:
UPDATE tabA outertab SET col1 = 'Value'
WHERE EXISTS (SELECT 1 FROM tabA innertab WHERE outertab.ROWID = outertab.ROWID AND ...)
Obviously the inner query is more complicated and uses other tables etc... but for the purposes of the example we dont need to include the detail.
My question is: When using rowid in a single SQL statement as a reference from a subquery to the outer statement is there a risk that external activities can change the rowid and those changes be reflected within the database session that my query is executing thus causing an inconsistency between the inner and outer SQL clause?
In response to the question which will follow this post: "Why don't you just use a PK", We would like to avoid maintaining a PK on the table as we are talking about very large volumes of data and we dont want to have to issue a call to a sequence if we can avoid it when we are inserting the data. If however there is a risk that this Update statement could fail or update the wrong rows then we may have to use a PK.
I know there is a lot of threads about this but I havnt been able to find one that someone has answered with any kind of confidence or clarity, any help would be much appreciated.
Thanks
Keith

Docs
A row's assigned rowid remains unchanged unless the row is exported and imported using the Import and Export utilities. When you delete a row from a table and then commit the encompassing transaction, the deleted row's associated rowid can be assigned to a row inserted in a subsequent transaction.

Hi Vijay,
Here's something to start with, you should be able to complete it.
First, combine your select and update statements:
update vt_mlr
   set aggregator_clli = field1
      ,aggregator_vpi_vci = field_2_n_3
      ,aggregator_slot = field4
      ,aggregator_port = field5
where user4 is not null;Then put these two
C1 := INSTR(vt_mlr_record.user4,' ',1,1);
Field1 := SUBSTR(vt_mlr_record.user4,1,C1-1);into
Field1 := SUBSTR(vt_mlr_record.user4,1,INSTR(vt_mlr_record.user4,' ',1,1) -1);And put it into the update statement, removing reference to record
(I have also removed default values for position and occurrence in instr function):
update vt_mlr
   set aggregator_clli = substr(user4, 1, instr(user4,' ') - 1)
      ,aggregator_vpi_vci = field_2_n_3
      ,aggregator_slot = field4
      ,aggregator_port = field5
where user4 is not null; I think you can do the rest from here ;-)

SQL UPDATE Statement Explaination (urgent please...)

Hi,
Could anyone explain for me what this statement will do:
update KPIR KR
set ( CA ) = (
select sum(sl.RRC_CONN_STP_ATT) CA
from PV_WCEL_SERVICE_LEVEL sl, UTP_MO um
where sl.GLOBAL_ID = um.CO_GID
group by sl.STARTTIME, um.OBJECT_INSTANCE
I could not understand how the mapping between the two tables will be ("um" clause is not used in the select statement and it is used only in the "where" and "group by" arguments) What does this mean?.
The actual problem is that when I execute the above SQL statement, it was take around just 3 minutes to be implemented. But after we upgrade from Oracle 8 to Oracle 9, this statement is taking around 3 hours to be implemented.
Anyone have any idea what is the problem?

Below is the plan:
KPIR table:
RNC_ID (str), PST ('YYYYMMDD_HH24'), CA (Numner)
1, 20061105_13, 0
1, 20061105_14, 0
1, 20061105_15, 0
2, 20061105_13, 0
2, 20061105_14, 0
2, 20061105_15, 0
3, 20061105_13, 0
3, 20061105_14, 0
3, 20061105_15, 0
4, 20061105_13, 0
4, 20061105_14, 0
4, 20061105_15, 0
PV_WCEL_SERVICE_LEVEL table:
GLOBAL_ID (str), STARTTIME ('YYYYMMDD_HH24'), RRC_CONN_STP_ATT (Number)
A1, 20061101_00, 9
A1, 20061101_01, 4
A1, 20061101_23, 3
A1, 20061130_23, 4
A2, 20061101_00, 3
A2, 20061101_01, 4
A2, 20061101_23, 1
A2, 20061130_23, 5
UTP_MO table;
RNC_ID (str), GLOBAL_ID (str), OBJECT_INSTANCE (str)
1, A1, <A1_NAME>
1, A2, <A2_NAME>
1, A9, <A9_NAME>
2, B1, <B1_NAME>
2, B2, <B2_NAME>
2, B9, <B9_NAME>
3, C1, <C1_NAME>
3, C2, <C2_NAME>
3, C9, <C9_NAME>
4, D1, <D1_NAME>
4, D2, <D2_NAME>
4, D9, <D9_NAME>
Now, I want to update the value of CA in table KPIR:
For instance, for RNC_ID='1' and at PST='20061105_13', the CA should equals to the sum of value RRC_CONN_STP_ATT for all GLOBAL_IDs under RNC_ID='1' and at STARTTIME '20061105_13'.
So, is this SQL UPDATE statement will do it?
update KPIR kr
set ( CA ) = (
select sum(sl.RRC_CONN_STP_ATT) CA
from PV_WCEL_SERVICE_LEVEL sl, UTP_MO um
where sl.GLOBAL_ID = um.GLOBAL_ID and kr.RNC_ID = um.RNC_ID and kr.PST = sl.STARTTIME
group by sl.STARTTIME, um.OBJECT_INSTANCE
And if so, why it is taking around 3 hours to be implemented? This issue is happened after upgrading from Oracle 8 to 9.
Really appreciate your help and thanks in advance.

Thank you all for the great ideas, you have been extremely helpful. Here is what we did and were able to resolve the query.
We started with Etbin's idea to create a table from the ext table so that we can index and reference easier than an external table, so we did the following:
SQL> create table ext_person as select P_ID,ED_ID,trim(F_NAME) fst_name,trim(L_NAME) lst_name from EXT_NAMES_CSV;
Table created.
SQL> desc ext_person

P_ID                                                                                         NUMBER

Sql Update Statement (complex)

Hi ,
A very good morning to all.
I am stuck in a problem , and i really hope for solutiion.
I have a dimension table (DIM_CAR) for which i need to write a update statement.
My table structure is :
C_ID           Startdate                       EndDate
7546343   2012-05-29 00:00:00   NULL
7546343   2012-05-18 00:00:00   2012-05-29 00:00:00
7546343   2012-05-14 00:00:00   2012-05-18 00:00:00
7546343   2012-05-10 00:00:00   2012-05-10 00:00:00
7546343   2012-05-10 00:00:00   2012-05-14 00:00:00
7546343   2012-03-22 00:00:00   2012-03-22 00:00:00
7546343   2012-03-15 00:00:00   2012-03-22 00:00:00
7546343   2012-02-02 00:00:00   2012-03-15 00:00:00
7546343   2012-01-31 00:00:00   2012-02-02 00:00:00
Now the scenario is Whenever any update comes in car , then it closes the previous record and open a new record(SCD)
For e.g the 1st update comes on 2012-02-02 , so it closes the last record (by putting 2012-02-02) in end date and open a new record by putting 2012-02-02 in startdate. Then update comes in 2012-03-15 and so on. The last record is for 2012-05-29 which is
still open as there is no update after that,
so whenever any update come it opens a new record with startdate value is extract date and enddate value NULL and closes the previous. Then after another update , that NULL value is replace by the new date and another record opens.
My prob is if you will closely analyse the dates , then there are some records missing in the above table due to which there are discrepencies in dates.
E.g. If u see the 6th row, startdate is 2012-03-22 and enddate is also 2012-03-22. But here in this case the enddate should be 2012-05-10(which is next update)
I need to write a sql script to update enddates with the latest update startdate in my table. I have 60000 of C_id which are affected.
COULD ANYONE plz Help.. I knw its difficult but u can give a try ..........Plz ask if anyone requires more info.

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> I have a dimension table (DIM_CAR) for which I need to write a update statement. My table structure is : <<
NO! This is a picture of the data; it is not DDL! Is this what you would have posted if you had manners?
CREATE TABLE Foobars
(c_id CHAR(7) NOT NULL,
foo_start_date DATE NOT NULL,
PRIMARY KEY (c_id, foo_start_date), -- my guess!!
CHECK (foo_start_date < foo_end_date),-- another guess!
foo_end_date DATE);
INSERT INTO Foobar
VALUES
('7546343', '2012-05-29', 'NULL),
('7546343', '2012-05-18', '2012-05-29'),
('7546343', '2012-05-14', '2012-05-18'),
('7546343', '2012-05-10', '2012-05-10'),
('7546343', '2012-05-10', '2012-05-14'),
('7546343', '2012-03-22', '2012-03-22'),
('7546343', '2012-03-15', '2012-03-22'),
('7546343', '2012-02-02', '2012-03-15'),
('7546343', '2012-01-31', '2012-02-02');
Now the scenario is Whenever any update comes in car, then it closes the previous record [sic: rows are not records! Please learn basic terms] and open a new record [sic](SCD).
What is “SCD” and why do you think it is meaningful to us? Here is an article on this topic.
Modifying Contiguous Time Periods
This article explains how to modify contiguous time periods that were described in Joe Celko’s article 'Contiguous Time Periods in SQL'. Joe describes the table itself that he calls the 'Kuznetsov History Table'. He explains how it is used to store contiguous
time intervals with constraint to ensure that the date periods really are contiguous, The editor suggested that I give a brief description of how to modify the data in the History table as this may not be entirely obvious.
When trusted constraints enforce data integrity, the data is guaranteed to be valid at the end of any statement, even if it is not committed. When we modify contiguous time periods, in order to get from one valid state to another we may need to insert a row
and update another one, or we may need to delete a row and update another one. This is one of those cases when MERGE really shines – it allows us to get from one valid state to another in one statement, inserting, updating, and deleting rows as needed.
CREATE TABLE Tasks
(task_id INT NOT NULL,
task_score INTEGER NOT NULL,
current_start_date DATE NOT NULL,
current_end_date DATE NOT NULL,
previous_end_date DATE NULL,
CONSTRAINT PK_Tasks_task_id_current_end_date
PRIMARY KEY (task_id, current_end_date),
CONSTRAINT UNQ_Tasks_task_id_previous_end_date
UNIQUE (task_id, previous_end_date),
CONSTRAINT FK_Tasks_task_id_previous_end_date
FOREIGN KEY (task_id, previous_end_date)
REFERENCES Tasks (task_id, current_end_date),
CONSTRAINT CHK_Tasks_previous_end_date_NotAfter_current_start_date
CHECK (previous_end_date <= current_start_date),
CONSTRAINT CHK_Tasks_current_start_date_Before_current_end_date
CHECK (current_start_date < current_end_date)
Some Easy Modifications.
It is easy to begin a new series of time periods
INSERT INTO Tasks
(task_id, task_score, current_start_date, current_end_date, previous_end_date)
VALUES (1, 100, '2010-1002', '2010-1023', NULL),
(1, 80, '2010-1023', '2010-11-03', '2010-1023');
It is just as easy to continue adding periods to the end of the series.
INSERT INTO Tasks
(task_id, task_score, current_start_date, current_end_date, previous_end_date)
VALUES(1, 98, '2010-11-20', '2010-11-25', '2010-11-03'),
(1, 75, '2010-11-26', '2010-11-27', '2010-11-25');
Deleting one or more rows from the end is just as easy, and we shall skip the example. As we have seen, it is easy to perform typical, the most common operations against history of periods.
However, some other operations are less easy and need more explanations. Now that we have enough test data, let us move on to more complex examples. Here is the test data at this moment:
Adding periods to the beginning.
Each series of periods has exactly one first period – this is enforced by the following constraint: Unique_task_id_and_previous_end_date
As a result, when we are inserting one or more periods to the beginning of the series, we have to update the period that used to be the first, as follows:
MERGE INTO Tasks
USING (VALUES (1, 98, '2009-03-01', '2009-03-06', NULL),
(1, 100, '2010-10-02', '2010-10-23', '2009-03-06')
) AS Source (task_id, task_score, current_start_date, current_end_date, previous_end_date)
ON Tasks.task_id = Source.task_id
AND Tasks.current_start_date = Source.current_start_date
WHEN MATCHED
THEN UPDATE
SET task_score = Source.task_score,
current_start_date = Source.current_start_date,
current_end_date = Source.current_end_date,
previous_end_date = Source.previous_end_date
WHEN NOT MATCHED
THEN INSERT (task_id, task_score, current_start_date, current_end_date, previous_end_date)
VALUES (Source.task_id, Source.task_score, Source.current_start_date,
Source.current_end_date, Source.previous_end_date);
Now we will verify that our test data looks as expected, with a new row at the beginning, and previous_end_date column is modified to point to the new row for the row that used to be the first before this modification:
We are also going to discuss some other scenarios, such as adding/deleting periods in the middle of the series. In all these cases we shall be using MERGE, and the DML looks quite similar, so let us wrap it up in a stored procedure.
CREATING A STORED PROCEDURE
The following code implements this merging functionality with a stored procedure that uses a table to hold teh new rows:
CREATE TABLE NewTasks
(task_id INTEGER NOT NULL,
task_score INTEGER NOT NULL,
current_start_date DATE NOT NULL,
current_end_date DATE NOT NULL,
previous_end_date DATE NULL,
deletion_flg CHAR(1));
CREATE PROCEDURE MergeNewTasks
AS BEGIN
MERGE INTO Tasks
USING (SELECT task_id, task_score, current_start_date, current_end_date, previous_end_date, deletion_flg
FROM NewTasks) AS Source
ON Tasks.task_id = Source.task_id
AND Tasks.current_start_date = Source.current_start_date
WHEN MATCHED AND deletion_flg = 'Y'
THEN DELETE
WHEN MATCHED
THEN UPDATE SET
task_score = Source.task_score,
current_start_date = Source.current_start_date,
current_end_date = Source.current_end_date,
previous_end_date = Source.previous_end_date
WHEN NOT MATCHED
THEN INSERT (task_id, task_score, current_start_date, current_end_date, previous_end_date)
VALUES (Source.task_id, Source.task_score, Source.current_start_date, Source.current_end_date, Source.previous_end_date);
END;
Let us use this stored procedure.
Filling a gap in the middle of the series
The following code fills the gap on November 25th.
CREATE TABLE NewTasks (..);
INSERT INTO NewTasks
(task_id, task_score, current_start_date, current_end_date, previous_end_date, deletion_flg)
VALUES (1, 75, '2010-11-25', '2010-11-26', '2010-11-25', 'N'),
(1, 80, '2010-11-26', '2010-11-27', '2010-11-26', 'N');
EXEC MergeNewTasks NewTasks = NewTasks;
Here is the data after this modification, with a period added in the middle fo the series:
Deleting a period in the middle of the series
The following code deletes the period added in the previous example.
CREATE TABLE NewTasks (..);
INSERT INTO NewTasks
(task_id, task_score, current_start_date, current_end_date,
previous_end_date, deletion_flg)
VALUES (1, 75, '2010-11-25', '2010-11-26', '2010-11-25', 'Y'),
(1, 80, '2010-11-26', '2010-11-27', '2010-11-25', 'N');
EXEC MergeNewTasks;
Here is the data after this modification:
Inserting two periods in the middle, and adjusting an exaisting period to make room for them. This is the last and most complex example involving our stored procedure:
CREATE TABLE NewTasks (..);
INSERT INTO NewTasks
(task_id, task_score, current_start_date, current_end_date, previous_end_date, deletion_flg)
VALUES (1, 98, '2010-11-20', '2010-11-22', '2010-11-03', 'N'),
(1, 75, '2010-11-22', '2010-11-23', '2010-11-22', 'N'),
(1, 98, '2010-11-23', '2010-11-25', '2010-11-23', 'N');
EXEC MergeNewTasks;

Using named parameters with an sql UPDATE statement

I am trying to write a simple? application on my Windows 7 PC using HTML, Javascript and Sqlite. I have created a database with a 3 row table and pre-populated it with data. I have written an HTML data entry form for modifying the data and am able to open the database and populate the form. I am having trouble with my UPDATE function. The current version of the function will saves the entry in the last row of the HTML table into the first two rows of the Sqlite data table -- but I'm so worn out on this that I can't tell if it is accidental or the clue I need to fix it.
This is the full contents of the function . . .
     updateData = new air.SQLStatement();
     updateData.sqlConnection = conn;
     updateData.text = "UPDATE tablename SET Gsts = "Gsts, Gwid = :Gwid, GTitle = :GTitle WHERE GId = ":GId;
          var x = document.getElementsById("formname");
          for (var i = 1, row, row = x.rows[i]; i++) {
               updateData.parameters[":GId"] = 1;
               for (var j = 0, col; col=row.cells[j]; j++) {
                    switch(j) {
                         case 0: updateData.parameters[":GTitle"] = col.firstChild.value; break;
                         case 1: updateData.parameters[":Gsts"] = col.firstChild.value; break;
                         case 2: updateData.parameters[":Gwid"] = col.firstChild.value; break;
Note: When I inspect the contents of the col.firstChild.value cases, they show the proper data as entered in the form -- it just isn't being updated into the proper rows of the Sqlite table.
Am I using the named parameters correctly? I couldn't find much information on the proper use of parameters in an UPDATE statement.

Thank you for the notes. Yes, the misplaced quotes were typos. I'm handtyping a truncated version of the function so I don't put too much info in the post. And yes, i = 1 'cuz the first rows of the table are titles. So the current frustration is that I seem to be assigning all the right data to the right parameters but nothing is saving to the database.
I declare updateData as a variable at the top of the script file
Then I start a function for updating the data which establishes the sql connection as shown above.
The correctly typed.text statement is:
        updateData.text = "UPDATE tablename SET Gsts=:Gsts, Gwid=:Gwid, GTitle=:GTitle WHERE GId=:GId";
(The data I'm saving is entered in text boxes inside table cells.) And the current version of the loop is:
        myTable = document.getElementById("GaugeSts");
        myRows= myTable.rows;
          for(i=1, i<myRows.length, i++) {
               updateData.parameters[":GId"]=i;
               for(j=0; j<myRows(i).cells.length, j++) {
                    switch(y) {
                         case 0: updateData.parameters[":GTitle"]=myrows[i].cells[y].firstChild.value; break;
                         case 1: updateData.parameters[":Gsts"]=myrows[i].cells[y].firstChild.value; break;
                         case 2: updateData.parameters[":Gwid"]=myrows[i].cells[y].firstChild.value; break;
                         updateData.execute;
The whole thing runs without error and when I include the statements to check what's in myrows[i].cells[y].firstChild.value, I'm seeing that the correct data is being picked up for assignment to the parameters and the update. I haven't been able to double check that the contents of the parameters are actually taking the data 'cuz I don't know how to extract the data from the parameters. ( The only reference I've found so far has said that it is not possible. I'm still researching that one.) I've also tried moving the position of the updateData execution statement to several different locations in the loop andstill nothing updates.
I am using a combination of air.Introspector.Console.log to check the results of code and I'm using Firefox's SQlite manager to handle the database. The database is currently sitting on the Desktop to facilitate testing and I have successfully updated/changed data in this table through the SQLite Manager so I don't think I'm having permission errors and, see below, I have another function successfully saving data to another table.
I currently have another function that uses ? for the parametersin the .text of a INSERT/REPLACE statement and that one works fine. But, only one line of data is being saved so there is no loop involved. I tried changing the UPDATE statement in this function to the INSERT/REPLACE just to make something save back to the database but I can't make that one work either.I've a (And, I've tried so many things now, I don't even remember what actually saved something --albeit incorrectly --to the database in one of my previous iterations with the for loops.)
I'm currently poring through Sqlite and Javascript tomes to see if I can find what's missing but if anything else jumps out at you with the corrected code, I'd appreciate some ideas.
