I have a table with a package size column with a data type of text that I need to convert to an integer for mathmatical reasons. The values in this column typically look something like "100ML","20GM","UD 20","13OZ" here is where it gets tricky there are occasionally values like "6X12ML","UD 5X6ML". The ones with the "X" in them I need to remove the "ML" I'm currently doing this with
Replace([TABLE_NAME].[COLUMN_NAME],"ML","")
in an expression column in a query. I can use nested Replace functions to remove the "ML","GM","OZ" and "UD ". All of my attempts to do this have failed, I figured the end solution would be something like
IIf([TABLE_NAME].[COLUMN_NAME] Like "X", (CInt(Left([TABLE_NAME].[COLUMN_NAME],InStr(1,[TABLE_NAME].[COLUMN_NAME],"X")-1))*CInt(Right([TABLE_NAME].[COLUMN_NAME],InStr(1,[TABLE_NAME].[COLUMN_NAME],"X")+1))),[TABLE_NAME].[COLUMN_NAME])
I have tried using a variation of the code above with no avail. All suggestions are appreciated, I would preffer to get this knocked out in one query but I do realize I can use and expression and just split the text before and after the "X" into two differenct expression columns. Then use another query to multiply the values.
QTY_ORDERED: IIf(InStr(1,Replace(Replace(Replace(Replace([STANDARD_PRICING].[PACKAGE_AMOUNT],"GM",""),"ML",""),"UD","")," ",""),"X")>1,[CRX_HISTORIC_PO].[QUANTITY]/Left(Replace(Replace(Replace(Replace([STANDARD_PRICING].[PACKAGE_AMOUNT],"GM",""),"ML",""),"UD","")," ",""),InStr(1,Replace(Replace(Replace(Replace([STANDARD_PRICING].[PACKAGE_AMOUNT],"GM",""),"ML",""),"UD","")," ",""),"X")-1)*Right(Replace(Replace(Replace(Replace([STANDARD_PRICING].[PACKAGE_AMOUNT],"GM",""),"ML",""),"UD","")," ",""),Len(Replace(Replace(Replace(Replace([STANDARD_PRICING].[PACKAGE_AMOUNT],"GM",""),"ML",""),"UD","")," ",""))-InStr(1,Replace(Replace(Replace(Replace([STANDARD_PRICING].[PACKAGE_AMOUNT],"GM",""),"ML",""),"UD","")," ",""),"X"))*-1,[CRX_HISTORIC_PO].[QUANTITY]/Replace(Replace(Replace(Replace([STANDARD_PRICING].[PACKAGE_AMOUNT],"GM",""),"ML",""),"UD","")," ","")*-1)
The code above is what I used to complete the task at hand.

I want to sort my column numbers at report level in SSRS instead of my query as I have some other columns sorted at query level and doing both sorts at query level don't work well. At the moment I get Columns order like 1, 10,2,3,4,5,6 instead of 1,2,3,4,5,6...10.
Once sorting is done I also want to add 'sales_' to the column name so I see sales_1, sales_2, sales_3 and so on. I understand this could be pretty straightforward but I'm new to SSRS. Thanks in advance.
The sort you are describing (1, 10,2,3,4) is a string sort, you need to convert the data type on that column to a numeric (in this case integer) type so that the sort is correct.
There are two solutions to this, you can add a calculated field to the record set, this can be helpful if you need to use this column multiple times, or you can simply use an expression for the sort order.
Right click on your dataset and select Add Calculated field, a dialog will open with all the column definitions for the query, here you can add your own custom fields.
For a custom field you will need an expression, which was the other options originally, so lets have a look at that component.
Edit the sort definition for the Tablix or group and select the field you want to sort on, to sort the way you would like the value needs to be numeric, we can use the CInt function to convert a value to an integer
NOTE: when using expressions to convert data types, if your data might not be convertible you may need to validate the value before conversion otherwise your
report execution will fail. The error messages are pretty helpful though and the expression dialog shows available functions an examples of usage for each of them.
For your second issue, use an expression in the field where you are displaying the data to concatenate the values, you can use the String.Format function or you can use simple string addition:
Expression Examples:
="sales_" + Fields!ItemValue.Value
="sales_" & Fields!ItemValue.Value
=String.Format("sales_{0}", Fields!ItemValue.Value)
I hope this helps you on your way, welcome to SSRS!
I have a PostgreSQL column of type text that contains data like shown below
(32.85563, -117.25624)(32.855470000000004, -117.25648000000001)(32.85567, -117.25710000000001)(32.85544, -117.2556)
(37.75363, -121.44142000000001)(37.75292, -121.4414)
I want to convert this into another column of type text like shown below
(-117.25624, 32.85563)(-117.25648000000001,32.855470000000004 )(-117.25710000000001,32.85567 )(-117.2556,32.85544 )
(-121.44142000000001,37.75363 )(-121.4414,37.75292 )
As you can see, the values inside the parentheses have switched around. Also note that I have shown two records here to indicate that not all fields have same number of parenthesized figures.
What I've tried
I tried extracting the column to Java and performing my operations there. But due to sheer amount of records I have, I will run out of memory. I also cannot do this method in batched due to time constraints.
What I want
A SQL query or a sequence of SQL queries that will achieve the result that I have mentioned above.
I am using PostgreSQL9.4 with PGAdmin III as the client
this is a type of problem that should not be solved by sql, but you are lucky to use Postgres.
I suggest the following steps in defining your algorithm.
First part will be turning your strings into a structured data, second will transform structured data back to string in a format that you require.
From string to data
First, you need to turn your bracketed values into an array, which can be done with string_to_array function.
Now you can turn this array into rows with unnest function, which will return a row per bracketed value.
Finally you need to slit values in each row into two fields.
From data to string
You need to group results of the first query with results wrapped in string_agg function that will combine all numbers in rows into string.
You will need to experiment with brackets to achieve exactly what you want.
PS. I am not providing query here. Once you have some code that you tried, let me know.
Assuming you also have a PK or some unique column, and possibly other columns, you can do as follows:
SELECT id, (...), string_agg(point(pt[1], pt[0])::text, '') AS col_reversed
FROM (
SELECT id, (...), unnest(string_to_array(replace(col, ')(', ');('), ';'))::point AS pt
FROM my_table) sub
GROUP BY id; -- assuming id is PK or no other columns
PostgreSQL has the point type which you can use here. First you need to make sure you can properly divide the long string into individual points (insert ';' between the parentheses), then turn that into an array of individual points in text format, unnest the array into individual rows, and finally cast those rows to the point data type:
unnest(string_to_array(replace(col, ')(', ');('), ';'))::point AS pt
You can then create a new point from the point you just created, but with the coordinates reversed, turn that into a string and aggregate into your desired output:
string_agg(point(pt[1], pt[0])::text, '') AS col_reversed
But you might also move away from the text format and make an array of point values as that will be easier and faster to work with:
array_agg(point(pt[1], pt[0])) AS pt_reversed
As I put in the question, I tried extracting the column to Java and performing my operations there. But due to sheer amount of records I have, I will run out of memory. I also cannot do this method in batched due to time constraints.
I ran out of memory here as I was putting everything in a Hashmap of
< my_primary_key,the_newly_formatted_text >. As the text was very long sometimes and due to the sheer number of records that I had, it wasnt surprising that I got an OOM.
Solution that I used:
As suggested my many folks here, this solution was better solved with a code. I wrote a small script that formatted the text as per my liking and wrote the primary key and the newly formatted text to a file in tsv format. Then I imported the tsv in a new table and updated the original table from the new one.
I have a query that is returning data from a database. In a single field there is a rather long text comment with a segment, which is clearly defined with marking tags like !markerstart! and !markerend!. I would like to have a query return with the string segment between the two markers removed (and the markers removed too).
I would normally do this client-side after I get the data back, however, the problem is that the query is an INSERT query that gets it's data from a SELECT statement. I don't want the text segment to be stored in the archival/reporting table (working with an OLTP application here), so I need to find a way to get the SELECT statement to return exactly what is to be inserted, which, in this case, means getting the SELECT statement to strip out the unwanted phrase instead of doing it in post-processing client-side.
My only thought is to use some convoluted combination of SUBSTRING, CHARINDEX, and CONCAT, but I'm hoping there is a better way, but, based on this, I don't see how. Anyone have ideas?
Sample:
This is a long string of text in some field in a database that has a segment that needs to be removed. !markerstart! This is the segment that is to be removed. It's length is unknown and variable. !markerend! The part of this field that appears after the marker should remain.
Result:
This is a long string of text in some field in a database that has a segment that needs to be removed. The part of this field that appears after the marker should remain.
SOLUTION USING STUFF:
I really don't like how verbose this is, but I can put it in a function if I really need to. It isn't ideal, but it is easier and faster than a CLR routine.
SELECT STUFF(CAST(Description AS varchar(MAX)), CHARINDEX('!markerstart!', Description), CHARINDEX('!markerend!', Description) + 11 - CHARINDEX('!markerstart!', Description), '') AS Description
FROM MyTable
You may want to consider implementing a CLR user-defined function that returns the parsed data.
The following link demonstrates how to use a CLR UDF RegEx function for pattern matching and data extraction.

You can use Stuff function or Replace function and replace your unwanted symbols with ''.
STUFF('EXP',START_POS,'NUMBER_OF_CHARS','REPLACE_EXP')
In MSSQL I can filter a query on a phone number like this:
where replace(phone,'-','') Like '%480555%'
I am trying to figure out how to do this on a Datasource. A normal query looks like this:
Dim stringFilter As String = String.Empty
String.Format("phone Like '%480555%'")
ViewCustomersBindingSource.Filter = stringFilter
However, this will not find any results because the datasource has the values with hyphens in it. REPLACE is not a valid argument for filtering.
My initial thought was to update the MSSQL View to strip the hyphens. However, for display, I would want to display the hyphens. I can not assume they will all look the same as some phone numbers might be a different country than the US.
Is there another way to filter on a telephone number and ignore the hyphens?
I dont think you can directly set a filter that ignores the hyphens (as in your first query) on your binding source. There is no String operations possible in the filter expression column. From this http://msdn.microsoft.com/fr-fr/library/system.windows.forms.bindingsource.filter.aspx the only string operation allowed is +.
But you can keep and display the original column which contains the hyphens, and add another column (without the hyphens) that you do not display, but that you use just for filtering.
With MSSQL, you can for example add a computed column that uses the REPLACE function.
Here is somes links that could help you to create a computed column:

I hope you can help me on this issue.
I am currently using Excel 2007 and I am creating a dynamic Planning/Time Sheet for our Team.
So far everything is going well.
Now unfortunately I am having an issue with the Conditional Format.
I am formatting the Cells in order to graphically show the current Status of the Person working. I am using the Conditional Format with a Formula example: =OFFSET(DataStart17D;COLUMN();ROW()-49;1;1)="PM"
Now I am trying to applying 2 conditions with a gradient fill of 2 colors like example: =AND(IF(OFFSET(DataStart17D;COLUMN();ROW()-49;1;1)="PM";TRUE;FALSE);IF(OFFSET(DataStart17D;COLUMN();ROW()-52;1;1)="AM";TRUE;FALSE)
Problem is, as soon as I use the IF or the AND Statement no condition is applied at all.
I have applied the above formula to the Cell itself and have received "TRUE" as the condition.
What is odd too is that if I apply =OFFSET(DataStart17D;COLUMN();ROW()-49;1;1)="PM" it works fine, if I use =IF(OFFSET(DataStart17D;COLUMN();ROW()-49;1;1)="PM";TRUE;FALSE) once again no condition applies.
I have searched the web for a Solution and could not find one yet :(
Would really be pleased if someone could help me on this one :)
Best Regards,
Richard J. Dana
You don't need IF Statment and TRUEs and FALSEs withih a Conditional Formatting formula. By its nature the formula is conditional.
Try something like:
=AND(OFFSET(DataStart17D;COLUMN();ROW()-49;1;1)="PM";OFFSET(DataStart17D;COLUMN();ROW()-49;1;1)="AM")
Once you do so, you'll see an additional problem. The two statements in your AND function are mutually exclusive, so it will never evaluate to TRUE.
EDIT:
There does seem to be an issue with the AND statement and multiple OFFSET statements that use ROW or COLUMN
Please note that I'm going to use commas instead of semicolons as function parameter separators here, otherwise it's too hard to convert. You'll have to change the commas back to semicolons.
Also note that you didn't need the last two arguments in either the ROW or COLUMN function in your original question. You had them set to a height and width of 1, which is the default, and is optional.
Here's a simplified example:
If you do something like:
OFFSET(DataStart17D,ROW()+1,COLUMNS())="PM"
it will evaluate to TRUE in the worksheet and also in the conditional formatting
If you do something like:
=AND(OFFSET(DataStart17D,ROW()+1,COLUMNS())="PM",OFFSET(DataStart17D,ROW()+1,COLUMNS())="PM")
which is just repeating the same statement twice, it will evaluate to TRUE in the worksheet, but won't trigger the conditional format.
All of the above is just as you stated in your question. The answer that I think works is to use ROWS and COLUMNS instead, like this:
=AND(OFFSET(DataStart17D,ROWS($1:2)+1,COLUMNS($A:A))="PM",OFFSET(DataStart17D,ROWS($1:2)+1,COLUMNS($A:A))="AM")
The above would be the formula for A2. Note that the first row or column inside the parentheses is anchored with a dollar sign. This gives you the count of rows or columns from A1, effectively the same thing as the ROW or COLUMN function.
