I have a SQL column named "details" and it contains the following data:
<changes><RoundID><new>8394</new></RoundID><RoundLeg><new>JAYS CLOSE AL6 Odds(1 - 5)</new></RoundLeg><SortType><new>1</new></SortType><SortOrder><new>230</new></SortOrder><StartDate><new>01/01/2009</new></StartDate><EndDate><new>01/01/2021</new></EndDate><RoundLegTypeID><new>1</new></RoundLegTypeID></changes>
<changes><RoundID><new>8404</new></RoundID><RoundLeg><new>HOLLY AREA AL6 (1 - 9)</new></RoundLeg><SortType><new>1</new></SortType><SortOrder><new>730</new></SortOrder><StartDate><new>01/01/2009</new></StartDate><EndDate><new>01/01/2021</new></EndDate><RoundLegTypeID><new>1</new></RoundLegTypeID></changes>
<changes><RoundID><new>8379</new></RoundID><RoundLeg><new>PRI PARK AL6 (1 - 42)</new></RoundLeg><SortType><new>1</new></SortType><SortOrder><new>300</new></SortOrder><StartDate><new>01/01/2009</new></StartDate><EndDate><new>01/01/2021</new></EndDate><RoundLegTypeID><new>1</new></RoundLegTypeID></changes>
What is the easiest way to separate this data out into individual columns? (that is all one column)
Try this:
SELECT DATA.query('/changes/RoundID/new/text()') AS RoundID
,DATA.query('/changes/RoundLeg/new/text()') AS RoundLeg
,DATA.query('/changes/SortType/new/text()') AS SortType
-- And so on and so forth
FROM (SELECT CONVERT(XML, Details) AS DATA
FROM YourTable) AS T
Once you get your result set from the sql (mysql or whatever) you will probably have an array of strings. As I understand your question, you wanted to know how to extract each of the xml nodes that were contained in the string that was stored in the column in question. You could loop through the results from the sql query and extract the data that you want. In php it would look like this:
// Set a counter variable for the first dimension of the array, this will
// number the result sets. So for each row in the table you will have a
// number identifier in the corresponding array.
$i = 0;
$output = array();
foreach($results as $result) {
$xml = simplexml_load_string($result);
// Here use simpleXML to extract the node data, just by using the names of the
// XML Nodes, and give it the same name in the array's second dimension.
$output[$i]['RoundID'] = $xml->RoundID->new;
$output[$i]['RoudLeg'] = $xml->RoundLeg->new;
// Simply create more array items here for each of the elements you want
$i++;
}
foreach ($output as $out) {
// Step through the created array do what you like with it.
echo $out['RoundID']."\n";
var_dump($out);
}

I'm trying to update "Count_Column" in "My_Table" to get the count of the array size in Array_Column
UPDATE TABLE [dbo1].[My_Table]
SET [Count_Column] as COUNT(Array_Column.test);
Array_Column in a column that has a JSON array in it
It's unclear why you want to store this information a second time, ideally you would just query it when needed.
Be that as it may, you need to break out the array using OPENJSON
UPDATE dbo1.My_Table
SET Count_Column = (
SELECT COUNT(*)
FROM OPENJSON(My_Table.Array_Column, '$.test')
);
This assumes that the array is located in a property called test, for example:
{
"test" : [
1,
2
]
}
would return 2
I have 2 foreach loops:
Loop 1: goes through a json file
Loop 2: goes through a database
i want to compare the results form the json to the results in the database.
// TRANSACTIONS
$transaction = json_decode(transaction_list($wallet_id), true);
// DATABASE ROWS
$rows = $db->run('SELECT * FROM transactions');
// loop through transactions
foreach ($transaction as $tx) {
$tx_id = $tx['id'];
}
// loop through database
foreach ($rows as $row) {
$id = $row['id'];
}
echo $id . " | " . $tx_id . "\n";
The results are only one line, Id like to get results for all the lines.

How do i get all the results from the database?
I tired a for loop to count the rows and produce one result for each one, but I just got the above line 12 times instead of 12 different results.
The goal is to be able to compare the json files results to the database and if theyre different to insert the json thats not already in the database into the database. for example, if the $tx_id doesnt exist to add the new transaction to the database. Maybe Im doing this wrong?
Hello i am trying to write an existing xlsx file using phpspreadsheet with setActiveSheetIndexByName(sheetname) and setcellvalue with reference and value, but it updates only the last record. spent more than 12 hours on this.
i tried foreach instead of while and used a counter to increment, but none worked.
<?php
include_once('db.php');
$prospect = $_REQUEST['prospect'];
require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$sql1 = mysqli_query($db,"select filename,sheetname, row, responsecol,compliancecol,response, compliance from spreadsheet where `prospect`='$prospect' and response <>'' order by row");
//$row=1;
while($row1 = mysqli_fetch_assoc($sql1))
{
$filename= $row1['filename']; //test.xlsx
$sheetname= $row1['sheetname']; // mysheet
$responsecol= $row1['responsecol'].$row1['row']; //D1
$response= $row1['response']; //response
$compliancecol= $row1['compliancecol'].$row1['row']; //C1
$compliance= $row1['compliance']; //compliance
$spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load($filename);
$spreadsheet->setActiveSheetIndexByName($sheetname)
->setCellValue($compliancecol,$compliance)
->setCellValue($responsecol,$response);
//$row++;
}
$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save("newfile.xlsx");
exit;
?>
i wish each of the row from mysqli result updates each reference cell with value.
The easys way is to set a Limit of 1 to your MySQL query. That takes only one value from your data. If you will the last you should sort DESC.
$sql1 = mysqli_query($db,"select filename,sheetname, row, responsecol,compliancecol,response, compliance from spreadsheet where `prospect`='$prospect' and response <>'' order by row DESC LIMIT 1");
Currently my code have simple tables containing the data needed for each object like this:
infantry = {class = "army", type = "human", power = 2}
cavalry = {class = "panzer", type = "motorized", power = 12}
battleship = {class = "navy", type = "motorized", power = 256}
I use the tables names as identifiers in various functions to have their values processed one by one as a function that is simply called to have access to the values.
Now I want to have this data stored in a spreadsheet (csv file) instead that looks something like this:
Name class type power
Infantry army human 2
Cavalry panzer motorized 12
Battleship navy motorized 256
The spreadsheet will not have more than 50 lines and I want to be able to increase columns in the future.
Tried a couple approaches from similar situation I found here but due to lacking skills I failed to access any values from the nested table. I think this is because I don't fully understand how the tables structure are after reading each line from the csv file to the table and therefore fail to print any values at all.
If there is a way to get the name,class,type,power from the table and use that line just as my old simple tables, I would appreciate having a educational example presented. Another approach could be to declare new tables from the csv that behaves exactly like my old simple tables, line by line from the csv file. I don't know if this is doable.
Using Lua 5.1
You can read the csv file in as a string . i will use a multi line string here to represent the csv.
gmatch with pattern [^\n]+ will return each row of the csv.
gmatch with pattern [^,]+ will return the value of each column from our given row.
if more rows or columns are added or if the columns are moved around we will still reliably convert then information as long as the first row has the header information.
The only column that can not move is the first one the Name column if that is moved it will change the key used to store the row in to the table.
Using gmatch and 2 patterns, [^,]+ and [^\n]+, you can separate the string into each row and column of the csv. Comments in the following code:
local csv = [[
Name,class,type,power
Infantry,army,human,2
Cavalry,panzer,motorized,12
Battleship,navy,motorized,256
]]
local items = {} -- Store our values here
local headers = {} --
local first = true
for line in csv:gmatch("[^\n]+") do
if first then -- this is to handle the first line and capture our headers.
local count = 1
for header in line:gmatch("[^,]+") do
headers[count] = header
count = count + 1
end
first = false -- set first to false to switch off the header block
else
local name
local i = 2 -- We start at 2 because we wont be increment for the header
for field in line:gmatch("[^,]+") do
name = name or field -- check if we know the name of our row
if items[name] then -- if the name is already in the items table then this is a field
items[name][headers[i]] = field -- assign our value at the header in the table with the given name.
i = i + 1
else -- if the name is not in the table we create a new index for it
items[name] = {}
end
end
end
end
Here is how you can load a csv using the I/O library:
-- Example of how to load the csv.
path = "some\\path\\to\\file.csv"
local f = assert(io.open(path))
local csv = f:read("*all")
f:close()
Alternative you can use io.lines(path) which would take the place of csv:gmatch("[^\n]+") in the for loop sections as well.
Here is an example of using the resulting table:
-- print table out
print("items = {")
for name, item in pairs(items) do
print(" " .. name .. " = { ")
for field, value in pairs(item) do
print(" " .. field .. " = ".. value .. ",")
end
print(" },")
end
print("}")
The output:
items = {
Infantry = {
type = human,
class = army,
power = 2,
},
Battleship = {
type = motorized,
class = navy,
power = 256,
},
Cavalry = {
type = motorized,
class = panzer,
power = 12,
},
}
I have one CSV file where the information is spread on two lines
Line 1 contains Name and age
Line 2 contains detail like address, city, salary, occupation
I want to combine 2 rows to insert it in a database.
CSV file :
Raju, 42
12345 west andheri,Mumbai, 100000, service
In SQL Server I can do by using cursor. But I have to do in SSIS.
For a similar case, i will read each line as one column and use a script component to fix the structure. You can follow my answer on the following question. It contains a step-by-step guide:
SSIS reading LF as terminator when its set as CRLF
I like using a script component in order to be able to store data from a different row in this case.
Read the file as a single column CSV into Column1.
Add script component and add a new Output called CorrectedOutput and define all columns from both rows. Also, mark Column1 as read.
Create 2 variables outside of row processing to 'hold' first row
string name = string.Empty;
string Age = string.Empty;
Use a split to determine line 1 or line 2
string[] str = Row.Column1.Split(',');
Use an if to determine row 1 or 2
if(str.Length == 2)
{
name = str[0];
age=str[1];}
else
{
CorrectedOutputBuffer.AddRow();
CorrectedOutputBuffer.Name = name; //This uses the stored value from prior row
CorrectedOutputBuffer.Age = age; //This uses the stored value from prior row
CorrectedOutputBuffer.Address = str[0];
CorrectedOutputBuffer.City = str[1];
CorrectedOutputBuffer.Salary = str[2];
CorrectedOutputBuffer.Occupation = str[3];
}
The overall effect is this...
On Row 1, you just hold the data in variables
On Row 2, you write out the data to 1 new row.
