I am looking to identify duplicate values in one column in a table.
I added a Column with name Unique_Ctr and have this formula.
Unique_Ctr =
COUNTROWS(FILTER('EnergyRoster',EARLIER('EnergyRoster'[NameID])-'EnergyRoster'[NameID])
)
I get the error, "Cannot convert value 'JorgeCordon' of type Text to type Number."
JorgeCordon is a value in the Column that I am trying to analyze for duplicates

I am trying to create a SQL loader CTL file and required to ignore rows that are starting with specific number in a column. suppose a column record_id =1211.6540D then ignore the row if the record column value starts with 1211.
I tried with position of numbers but the columns values before the record_id are not constant.
Can you please help.
I want to update my columns for rows specified by WHERE command, but I want to update my field in a way that it extracts number part of the string from each specified field, multiplies that with a number (that I will specify) and give number output in all those specific fields extracted by WHERE command in that column.
For example, assume I want to update all my fields in a column which are like (5.6 AUD/1000, 4.5 AUD/1000, 9.7 AUD/1000), so I want to first identify fields ending with /1000 and update only those fields in the column by multiplying the number part of the string (which is 5.6, 4.5, 9.7) with any number (let's say 10). I want that other fields on the column remains unchanged.
SELECT * from sorted WHERE Column8 REGEXP '/1000$';
gives me all the specific fields that I wish to update. But I want to update them in the way I specified above, which is that I want to extract number part from the string and multiply that with a number and update those fields only.
I am able to extract all the fields with the condition I mentioned, I'm facing difficulty in update these fields in the column.
SELECT * from sorted WHERE Column8 REGEXP '/1000$';
SELECT CAST(Column8 AS UNSIGNED)*10 FROM sorted
wHERE
column8 REGEXP '/1000$';
The above code gives me required updated fields, but I want them reflected in my column.
I expect my output to be a column where only those fields ending with '/1000' should get updated in a way that the number part of the string is multiplied with 10.
I have casted the varchar field named string to decimal type and multiplied with static value 10 . I have checked in sql server.
DECLARE #temp TABLE
(
string NVARCHAR(50)
)
INSERT INTO #temp (string)
VALUES
('5.6 AUD/1000'),
('4.5 AUD/1000'),
('9.7 AUD/1000')
select cast(left(string, patindex('%[^0-9./]%', string) - 1) As decimal(18,2))* 10
from #temp
Say I have a simple mysql table containing a name field which is just a varchar. The name field contains a string of the following format. "channelname,unix_timestamp,unix_timestamp". e.g. "bbc1,123456789,123456889". I need to select all rows, where a channelname matches, and where a given timestamp falls within the range of the 2 timestamps. For example, given the timestamp 123456800, and the channelname 'bbc1' The above record should be selected.
How I would accomplish this is to first select all records with "name like 'bbc1,%' split out the two timestamp fields in the calling code, and filter the results there to those containing the given timestamp. Is there a better, more efficient way. My DB could have a very large number of records which match "name like 'bbc1,%'", and it's only expected to grow as time goes on.
I unfortunately don't have the ability to alter the table to add the two timestamp fields, the only thing I have to go on is that single name field. It's also possible that the name field may contain some arbitrary string not of the given format for some records, however all records which start with the given channel name should match this format.
I have a table with two fields, IDCopy and ID. I want to copy the value of ID into IDCopy because ID is a number field and I need a second copy of this field as a text field.
I am used to doing things like this on sql server
UPDATE table SET table.IDCopy= table.ID;
But when I try to run that query in access it asks me for the parameter value of ID. What is the syntax for setting one column in a table to another column in Access?
You can use CStr() to cast the ID number to text. This should work when IDCopy is text and ID is numeric.
UPDATE [table] SET IDCopy = CStr(ID);
I bracketed the table name because table is a reserved word.
If Access still thinks ID is a parameter with this query, then [table] does not include a field named ID.
Goal:
Combine two column named first and lastname, from the same table A and then transfer it to column fullname in table B from a another
relational database.
Column first and lastname has the same datatype as fullname. The datatype is varchar(50) or varchar(100).
Problem:
I can't make the transaction to have the same datatype
You need to use the type cast expression DT_STR in Derived Column transformation so that the output from Derived Column transformation is still in varchar data type.
Below shown Derived Column Transformation shows two new columns.
First new column FullName takes in two input columns FirstName and LastName. Concatenates the columns with a space to separate them and then type casts to DT_STR. In (DT_STR, 100, 1252), 100 represents the length of the output column, 1252 represents the code page.
Second new column FullNameNoCast simply concatentates the two input columns FirstName and LastName. This will result in Unicode data type.
Since, you mentioned that your destination is of varchar data type. I believe that you are not type casting the new column in Derived Column transformation. That might lead to the error you are facing.
Hope that helps.
