Need to remove multiple rows within a CSV file in Excel based on a match in column L on sheet1 with column A on sheet2. The content is email addresses. How can I achieve this? So, if sheet2 column A has an email address that matches any of the email addresses in sheet1 - Column L, than it should remove the entire row from sheet1 where that email address is located. Sheet1 below: Sheet2 below: @mehow, here's the image I get when I run your code as a module: This will work, very fast for what you are looking to do as it doesn't involve ANY loops.

I have an extremely large table (4M+ rows) with disk space of more than 40Gb (14Gb data and 28Gb index). I needed fulltext search on multiple fields both combined and separated, meaning that I needed to make it possible to fulltext search on both single columns and multiple columns together, like below: for combined search SELECT `column_a`, `column_b` FROM `table_1` WHERE MATCH (`column_a`, `column_c`, `column_x`) AGAINST ('+$search_quesry*' IN BOOLEAN MODE); for separate search SELECT `column_a`, `column_b` FROM `table_1` WHERE MATCH (`column_a`) AGAINST ('+search_query*' IN BOOLEAN MODE);

I have dataframe looks like this: df Data1 Data2 Data3 A XX AA A YY AA B XX BB B YY CC C XX DD C YY DD D XX EE D YY FF I want to delete all the row (column data3) based on two columns (data1 and data2) with the condition if the data on data3 is same the delete. my expected result looks like this: Data1 Data2 Data3 B XX BB B YY CC D XX EE D YY FF how to do it? Using groupby + transform with nunique yd=df[df.groupby(['Data1']).Data3.transform('nunique').gt(1)].copy() Out[506]: Data1 Data2 Data3 2 B XX BB 3 B YY CC 6 D XX EE 7 D YY FF You can also use a groupby with nunique , and a selection of

Original Issue: I am using readdir to snag file names from multiple directories. I was wondering if there is a way to arrange the data so that each time it starts a new directory it makes a new column i.e. ---| user1 | user2 | user3 | ---| file1a | file2a | file3a | ---| file1b | file2b | file3b | ---| file1c | file2c | file3c | ---| file1d | ^ | file3d | ---| file1e | | | ^ | ---| ^ | end | | | ---| | | dir2 | end | ---| end | #start | dir3 | ---| dir1 | col3 | etc. | ---| #start | | | ---| col2 | | | if this is possible that would be great; as far as displaying the user names across the top

I have a query result like this : Date User1 User2 User3 .... ---------------------------------- 1/1/2000 55 78 98 ... 1/1/2001 26 33 56 ... 1/1/2002 88 67 12 ... The number of columns is not known because it is the result of a pivot query. I would like to change the name the columns to something that looks like this : Date User1 (blue) User2 (green) User3(brown) The color is an information I retrieve from another table. How can I achieve this ? Thanks Edit : Here is the query. DECLARE @cols AS NVARCHAR(MAX), @query AS NVARCHAR(MAX) select @cols = STUFF((SELECT distinct ',' + QUOTENAME(C.Name)
