I tried to change a char column to date column using STR_TO_Date but was getting a error message. That column actually has dates but not in a proper order. So for me to perform any date functions i need to modify the column into dates but not as char. Pls help

I have a table ORDERS which contains column ORDER_DATE. I have created a Chart as a Bar type. I want the chart to show the amount of orders in a given date or range.
I'm following this Youtube tutorial which shows how to create a datepicker that returns a range in a Report. I'm trying to replicate this in a chart.
What I've done so far
Created datepicker items P5_DATE_FROM and P5_DATE_TO
Changed the Series Source Type to SQL Query
select ORDER_ID,
ORDER_NUMBER,
TO_CHAR(ORDER_DATE, 'YYYY-MM-DD') AS ORDERDATE,
STORE_ID,
FULL_NAME,
EMAIL,
CITY,
STATE,
ZIP_CODE,
CREDIT_CARD,
ORDER_ITEMS,
APEX$SYNC_STEP_STATIC_ID,
APEX$ROW_SYNC_TIMESTAMP
from ORDERS_LOCAL
where TO_CHAR(ORDER_DATE, 'YYYY-MM-DD') between :P5_DATE_FROM and :P5_DATE_TO
Source Page Items to Submit added P5_DATE_FROM,P5_DATE_TO
I basically followed the exact steps of the video. However, since the video is for a report and mine is for a chart, the chart isn't actually returning any data.
I think this is because for charts there are additional fields I need to configure. I noticed the video didn't cover Column Mapping and I'm a bit confused to what to enter here.
----------------UPDATE-------------
I've followed Koen's instructions from his answer. It seems like to TO_CHAR function was causing the error. I've updated the SQL Query to below:
select ORDER_ID,
ORDER_NUMBER,
ORDER_DATE,
STORE_ID,
FULL_NAME,
EMAIL,
CITY,
STATE,
ZIP_CODE,
CREDIT_CARD,
ORDER_ITEMS,
APEX$SYNC_STEP_STATIC_ID,
APEX$ROW_SYNC_TIMESTAMP
from ORDERS_LOCAL
where ORDER_DATE between TO_DATE(:P5_DATE_FROM,'YYYY-MM-DD') and TO_DATE(:P5_DATE_TO,'YYYY-MM-DD')
However, on the Page Designer I cannot save and run page until I select Column Mapping - Label and Value. I've set the Label as ORDER_DATE but I am unsure of what to select for the Value.
Setting the Value to ORDER_DATE shows an error Ajax call returned server error ORA-01403: no data found for CHART Count Orders by Date.
and selecting any other Value such as ORDER_NUMBER or ZIP_CODE populates the chart with the actual integer value of the column (ex: ZIP_CODE returns a chart of x-axis: date, y-axis: actual zip code numbers)
I see 2 possible issues.
You submit P5_DATE_FROM and P5_DATE_TO but the source has P1_DATE_FROM and P1_DATE_TO - not sure that is a typo but it should all be the same...
The where clause is wrong. This
from ORDERS_LOCAL
where TO_CHAR(ORDER_DATE, 'MM-DD-YYYY') between :P1_DATE_FROM and :P1_DATE_TO
should be
from ORDERS_LOCAL
where ORDER_DATE between TO_DATE(:P1_DATE_FROM,'MM-DD-YYYY') and TO_DATE(:P1_DATE_TO,'MM-DD-YYYY')
Reason: the column orders_local.order_date is of datatype DATE. If you convert it to a string using TO_CHAR then it will be a string comparison, not a date comparison.
Note that bind variables P1_DATE_FROM and P1_DATE_TO are strings - they're defined in the DOM on the html page and that has no concept of oracle datatypes so everything is just a string. If they're used as such in a date comparison, you're relying on implicit conversion by the database. It's safer to do explicit conversion using the TO_DATE function.
--UPDATE--
Your question starts with "I want the chart to show the amount of orders in a given date or range.". Well... there is your answer. The "Value" is the amount of orders on each day. Update your source query to include a count of the orders and group by day. Then make your value attribute the column that has the count.
I'm trying to Add Custom Column in Power Query with the objective to return a Table from a List of dates.
The syntax used is as follows below:
= Table.AddColumn(TypeDate, "AddTable", each Table.FromList(
List.Dates([Date_begin],1,#duration(1,0,0,0)
)))
where:
TypeDate is the name of last step in Power Query
"AddTable" is the name of added custom column
[Date_begin] is a column with dates to be considered as the start of my list
Although the syntax seems correct, Power Query returns an error described as follows:
Expression.Error: We could not convert the value #date(2021, 1, 1) on to Text.
Details:
Value=01/01/2021
Type=[Type]
Does anyone know how to handle this problem?
I'll show an image where Power Query shows the error.

Your question is unclear
You want to add a column that has a table of dates for each row, using Date_Begin and Mes_Final?
#"Added Custom" = Table.AddColumn(TypeDate, "AddTable", each Table.TransformColumnTypes(Table.FromList({Number.From([Date_Begin])..Number.From([Mes_Final])}, Splitter.SplitByNothing(), {"date"}),{{"date", type date}}))
I have one thing to solve.I want to add new column as "Complete or Not" deponding on Action Column.If one date have sign_in and sign_out,data in new column is "Complete" for that date.
Pls help me

I am trying to get today's current date and format it to yymmdd because my table name change daily. e.g. MICRINFO210616 and tomorrow it will be MICRINFO210617
When I run thecode below I get the following error:
Expression.Error: The key didn't match any rows in the table.
Key=
Schema=dbo
Item=MICRINFO210617
Table=[Table]
code:
let
Source = Sql.Database("TEST", "TEST"),
formattedDate = Date.ToText(DateTime.Date(DateTime.LocalNow()), "yyMMdd"),
combine = "MICRINFO" & formattedDate,
dbo_MICRINFO210616 = Source{[Schema="dbo", Item=combine]}[Data]
in
dbo_MICRINFO210616
Make sure the account you're using has at least read permissions (to the new table).
Check if the structure of both tables is the same (same number of columns, same datatype).
I want to move a single value from column B to column A, how can I achieve it in the most simplest way in Power Query / Query Editor (Power BI)?
Please see attached images.
I know I might need to declare a variable so please enlighten me. By the way, I will delete row 1 afterwards, promote my headers, and rename column2 as PERIOD.
Thank you.
This might be along the lines of what you want to do.
If I start with this table named as Table1:
Then I click on the fx to the left of the formula bar:
And type = Table.InsertRows(Source, Table.RowCount(Source), {[Column2 = Source[KP20 rate]{0}, KP20 rate = null, Column4 = null]}) into the formula bar:
I used Table.InsertRows to create a new row in Table1. Source is the name of the latest state of Table1 after it is pulled into Power Query and before I do this step. So I actually use Source as the name of the table for this step instead of Table1. (Each applied step basically results in its own table. You probably know this already, but others may not.) So for this step I use Source as the table name in the Table.InsertRows statement. Then, since I want the new row to appear at the bottom of Source, I just enter the Table.RowCount of Source as the row number location for the new row. Then I enter each of the Columns' names and their values to be added. For Column2, I entered the value "Source[KP20 rate]{0}." Source[KP20 rate]{0} basically treats column KP20 rate as a list, where {0} serves as a pointer to the first item in the list. To target the second item in Source[KP20 rate] you would use Source[KP20 rate]{1}. You can see that I set the values for the other two columns (KP20 rate and Column4) to null.
The result:
Here's the M code in case you want to see it:
let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
Custom1 = Table.InsertRows(Source, Table.RowCount(Source), {[Column2 = Source[KP20 rate]{0}, KP20 rate = null, Column4 = null]})
in
Custom1
