Is there a way to TRIM all data in a SELECT * FROM statement?

I am trying to select and trim all the entries from a table using the following statement: SELECT TRIM(*) FROM TABLE But I get an error. Is there a way to return all entries selected so they are trimmed for blank characters at the beginning and end of each string? You need to specify each string column by hand: SELECT TRIM(col1), --LTRIM(RTRIM(...)) If RDBMS is SQL Server TRIM(col2), TRIM(col3), TRIM(col4) -- ... FROM table There is another problem with your proposal. * is placeholder for each column in table so there will be problem with trimming date/decimal/spatial data ... . Addendum Using

C# Trim() vs replace()

由 喜夏-厌秋 提交于 2019-11-30 17:46:41
In a C# string if we want to replace " " in a string to string.empty , is it fine to use stringValue.Trim() or stringValue.replace(" ", string.empty) . Both serve the same purpose. But which one is better? Nick Zimmerman Trim() and Replace() do not serve the same purpose. Trim() removes all whitespace characters from the beginning and end of the string. That means spaces , tabs , new lines , returns , and other assorted whitespace characters . Replace() only replaces the designated characters with the given replacement. So Replace(" ", string.empty) will only replace spaces with empty strings.

MySQL select fields containing leading or trailing whitespace

I can use the MySQL TRIM() method to cleanup fields containing leading or trailing whitespace with an UPDATE like so: UPDATE Foo SET field = TRIM(field); I would like to actually see the fields this will impact before this is run. I tried this but returns 0 results: SELECT * FROM Foo WHERE field != TRIM(field); Seems like this should work but it does not. Anyone have a solution? Also, curious why this does not work... eggyal As documented under The CHAR and VARCHAR Types : All MySQL collations are of type PADSPACE . This means that all CHAR and VARCHAR values in MySQL are compared without

问题 My data looks like ID LPNumber 1 30;#TEST123 2 302;#TEST1232 How can I update MyText to drop everything before the # and including the #, so I'm left with the following: ID LPNumber 1 TEST123 2 TEST1232 I've looked at SQL Server Replace, but can't think of a viable way of checking for the ";" 回答1: Use CHARINDEX(), LEN() and RIGHT() instead. RIGHT(LPNumber, LEN(LPNumber) - CHARINDEX('#', LPNumber, 0)) 回答2: On the MSDN REPLACE page, the menu on the left gives the complete list of string

问题 I was looking for a trim function in JavaScript which doesn't exist and some code on Googling suggests that use: function trimStr(str) { return str.replace(/^\s+|\s+$/g, ''); } I want to know how str.replace(/^\s+|\s+$/g, '') works. I understand that this is some form of regular expression but dont know what it is doing. 回答1: /^\s+|\s+$/g searches for whitespace from either the beginning or the end of the string. The expression can be split into two parts, ^\s+ and \s+$ which are separated by

Iterate through Object's own Strings & Trim each

由 感情迁移 提交于 2019-11-30 03:54:08
I have multiple large objects which each have about 60 strings. I have to trim all those strings, and I'd like to do so without having to go this.mystring = this.mystring.Trim(). Instead, I'm looking for a way to automatically have each object discover its own strings and then perform the operation. I know a little bit about reflection, but not enough, but I think this is possible? Also, I'm not sure if this matters, but some string properties are read-only (only have a getter), so those properties would have to be skipped. Help? Jon Skeet Well, it's easy enough to get all the properties, and
