So I have 2 variable for storing the selected time of the user ('time_to' and 'time_from) with these sample data('7:30','8:00')
How can I save these two into 1 column('c_time') so it would look like this('7:30-8:00')?
if i understand you correctly, you can create a column of string (varchar) type. and then create the data for your column like this :
$time_to = '7:30';
$time_from= '8:00';
$colValueToBeStored = "(".$time_to."-".$time_from.")";
then just put $colValueToBeStored inside your column.
and to reverse it:
$colValueToBeStored = "(7:30-8:00)";
$res = explode("-",str_replace([")","("],"",$colValueToBeStored));
$time_to = $res[0];
$time_from = $res[1];
define your c_time column type as JSON, that way you can store multiple values, as it will be easier to retrieve as well. Like,
...
$cTime['time_to'] = "7:30";
$cTime['time_from'] = "8:00";
$cTimeJson = json_encode($cTime);
// save to db

i have 2 tables User and subadmin consider user have 3 columns and subadmin has 2 column i want to get 3+2 (5 column) data into a single veriable array
the technique i want to use is that in user table i have id which is same in subadmin table with sub_admin_id(column) how i can use eloquent model to first link id with sub_admin_id and then into a single query get 5 column in single veriable array
here i am using to get data
$subadmindata = User::find($id)->get(); // [column1 ,column2 ,column3 ]
$subadmindata1 = SubAdmin::find($id)->get(); // [column1 ,column2 ]
output should be
$data = // [column1 ,column2 ,column3 , column4 ,column5 ]
note i dont want to use array merge or combine method i want to use eloquent model for my learning
you could use concat like this
$subadmindata = User::find($id)->get();
$subadmindata1 = SubAdmin::find($id)->get(); // it will return array of collections
$data = $subadmindata->concat($subadmindata1);
Notice when you use get after find it stop it's jobs so there is no need to find here
get() method will give you a collection not array, so you can merge two collection as follows.
$subadmindata = User::find($id)->get();
$subadmindata1 = SubAdmin::find($id)->get();
$data = $subadmindata->merge($subadmindata1);
You can't use find with get(Assuming that you need a one result not all of the users). Try this. But looks like you need build the relationships correctly first. Anyway, quick answer is below.
$userCols = User::select('column1','col2','col3')->find($id);
$subAdminCols = SubAdmin::select('col4','col5')->find($id);
$cols = array_merge($userCols->toArray(), $subAdminCols->toArray());
try this
in user model
public function subadmin(){
return $this->hasOne(SubAdmin::class,'sub_admin_id');
}
in controller
$sub_admins = User::find($id);
dd($sub_admins->subadmin->sub_admin_id)
you can use php ... operator to to push data
example like this
$subadmindata = User::find($id)->get()->toArray(); // [column1 ,column2 ,column3 ]
$subadmindata1 = SubAdmin::find($id)->get()->toArray(); // [column1 ,column2 ]
array_push($subadmindata, ...$subadmindata1);
return $subadmindata

In old DB i have a data in one column as
<ADDRESS>
<CITY>ABC</CITY>
<STATE>PQR</SERVICE>
</ADDRESS>
In my new DB i want this data to be stored in KEY VALUE fashion like:
USER_ID KEY VALUE
1 CITY ABC
1 STATE PQR
Someone please help me how to migrate this kind of data using TALEND tool.
Design job like below.
tOracleInput---tExtractXMLFiled---output.
tOracleInput component you can select XML column and make datatype as String.
tExtractXmlFiled component pass this XML column as " XML Filed" and set the Loop xpath Expression as "/ADDRESS"
Add new two Columns in output Schema of tExtractXmlFiled for city & STATE
Set XPath Query in Mapping for city "/ADDRESS/CITY" and for STATE "/ADDRESS/STATE"
Now you have both the values in output.
See the image for more details.
as I explain in your previous post you can follow the same approach for making Key value pair.
how-to-split-one-row-in-different-rows-in-talend
Or you can use tUnpivot component as you did here.
As you said source data has Special character then use below expression to replace it.
Steps: after oracle input add tMap and use this code for replacement of special symbol
row24.XMLField.replaceAll("&", "<![CDATA["+"&"+"]]>")
once that is done execute the job and see the result it should work.
I'd use tJavaFlex.
Component Settings:
tJavaFlex schema:
In the begin part, use
String input = ((String)globalMap.get("row2.xmlField")); // get the xml Fields value
String firstTag = input.substring(input.indexOf("<")+1,input.indexOf(">"));
input = input.replace("<"+firstTag+">","").replace("</"+firstTag+">","");
int tagCount = input.length() - input.replace("</", "<").length();
int closeTagFinish = -1;
for (int i = 0; i<tagCount ; i++) {
in the main part, parse the XML tag name and value, and have the output schema contain that 2 additional column. MAIN part will be like:
/*set up the output columns */
output.user_id = ((String)globalMap.get("row2.user_id"));
output.user_first_name = ((String)globalMap.get("row2.user_first_name"));
output.user_last_name = ((String)globalMap.get("row2.user_last_name"));
Then we can calculate the key-value pairs for the XML, without knowing the KEY values.
/*calculate columns out of XML */
int openTagStart = input.indexOf("<",closeTagFinish+1);
int openTagFinish = input.indexOf(">",openTagStart);
int closeTagStart = input.indexOf("<",openTagFinish);
closeTagFinish = input.indexOf(">",closeTagStart);
output.xmlKey = input.substring(openTagStart+1,openTagFinish);
output.xmlValue = input.substring(openTagFinish+1,closeTagStart);
tJavaFlex End part:
}
Output looks like:
.-------+---------------+--------------+------+--------.
| tLogRow_2 |
|=------+---------------+--------------+------+-------=|
|user_id|user_first_name|user_last_name|xmlKey|xmlValue|
|=------+---------------+--------------+------+-------=|
|1 |foo |bar |CITY |ABC |
|1 |foo |bar |STATE |PQR |
'-------+---------------+--------------+------+--------'
Thanks in advance for any help on this one.
I have a model in rails that includes a postgresql text column.
I want to append (i.e. mycolumn = mycolumn || newdata) data to the existing column. The sql I want to generate would look like:
update MyOjbs set mycolumn = mycolumn || newdata where id = 12;
I would rather not select the data, update the attribute and then write the new data back to the database. The text column could grow relatively large and I'd rather not read that data if I don't need to.
I DO NOT want to do this:
#myinstvar = MyObj.select(:mycolumn).find(12)
newdata = #myinstvar.mycolumn.to_s + newdata
#myinstvar.update_attribute(:mycolumn, newdata)
Do I need to do a raw sql transaction to accomplish this?
I think you could solve this problem directly writing your query using the arel gem, that's already provided with rails.
Given that you have these values:
column_id = 12
newdata = "a custom string"
you can update the table this way:
# Initialize the Table and UpdateManager objects
table = MyOjbs.arel_table
update_manager = Arel::UpdateManager.new Arel::Table.engine
update_manager.table(table)
# Compose the concat() function
concat = Arel::Nodes::NamedFunction.new 'concat', [table[:mycolumn], new_data]
concat_sql = Arel::Nodes::SqlLiteral.new concat.to_sql
# Set up the update manager
update_manager.set(
[[table[:mycolumn], concat_sql]]
).where(
table[:id].eq(column_id)
)
# Execute the update
ActiveRecord::Base.connection.execute update_manager.to_sql
This will generate a SQL string like this one:
UPDATE "MyObjs" SET "mycolumn" = concat("MyObjs"."mycolumn", 'a custom string') WHERE "MyObjs"."id" = 12"
I can get column list from the table using LINQ like this:
OrderDataContext ctx = new OrderDataContext();
var cols = ctx.Mapping.MappingSource
.GetModel( typeof( OrderDataContext ) )
.GetMetaType( typeof( ProductInformation ) )
.DataMembers;
This gives me the list of columns, so I can do this:
foreach ( var col in cols )
{
// Get the value of this column from another table
GetPositionForThisField( col.Name );
}
So this all works, I can iterate through column list and pull the values for those columns from an another table (since the column names are the keys in that another table), so I don't have to do switch....or lot of if...then...
Now the question:
After I get these values, how do I populate the entity in order to save it back? I would normally go like this:
ProductInformation info = new ProductInformation();
info.SomeField1 = val1;
info.SomeField2 = val2;
ctx.ProductInformation.InsertOnSubmit( info );
ctx.SubmitChanges();
But how to use the same column collection from above to populate the columns while iterating over that, when there is no such thing as:
info["field1"].Value = val1;
Thanks.
Just fetch the object that you want to modofy, set the property and call SubmitChanges. There is no need to create a new object and insert it. The Context tracks your changed properties and generates the update statement accordingly. In your case you may want to set the properties via reflection rather than manually since you are reading them from another table.
You'll need to use reflection. Assuming you can get the PropertyInfo from the metadata:
PropertyInfo property = GetPropertyForThisField(col.Name);
property.SetValue(info, val1, null);
I have a table called UserManagement that contains information about the user.This table gets updated whenever new user is created. If i create two users then i need check whether two users are actually created or not. Table contains ID,UserName,FirstName,LastName,Bdate..ctc. Here ID will be generated automatically.
I am running Selenium-TestNG script.Using Selenium,how can i get the UserName of the two users which i have created? Should i have to iterate through table? If so how to iterate through the table?
Use ISelenium.GetTable(string) to get the contents of the table cells you want. For example,
selenium.GetTable("UserManagement.0.1");
will return the contents of the table's first row and second column. You could then assert that the correct username or usernames appear in the table.
Get the count of rows using Selenium.getxpathcount(\#id = fjsfj\td\tr") in a variable rowcount
Give the columncount in a variable
Ex:
int colcount = 5;
Give the req i.e New user
String user1 = "ABC"
for(i = 0;i <=rowcount;i++)
{
for(j=0;j<=colcount;j++)
{
if (user1==selenium.gettable("//#[id=dldl/tbody" +i "td"+j))
{
system.out.println(user1 + "Inserted");
break;
}
break;
}
}
Get the number of rows using:
int noOfRowsInTable = selenium.getXpathCount("//table[#id='TableId']//tr");
If the UserName you want to get is at fixed position, let's say at 2nd position, then for each row iterate as given below:
selenium.getText("xpath=//table[#id='TableId']//tr//td[1]");
Note: we can find the number of columns in that table using same procedure
int noOfColumnsInTable = selenium.getXpathCount("//table[#id='TableId']//tr//td");
Generically, something like this?
table = #browser.table(:id,'tableID')
table.rows.each do |row|
# perform row operations here
row.cells.each do |cell|
# do cell operations here
end
end
