问题 I'm trying to remove blank spaces that appear in a CHAR column within DB2. I received some helped here with the function TRANSLATE to determine if Left contained records that began with three letters: select pat.f1, hos.hpid, hos.hpcd from patall3 pat join hospidl1 hos on pat.f1=hos.hpacct where TRANSLATE( LEFT( hos.hpid, 3 ), 'AAAAAAAAAAAAAAAAAAAAAAAAA', 'BCDEFGHIJKLMNOPQRSTUVWXYZ' ) <> 'AAA' order by pat.f1; But as you can see in my screenshot, there are records that remain, presumably

问题 I am transferring some SQL query into C# code, now I am having problem understand the following query. So far my understanding to the following query is: If PREFIX is between 0 to 99 , then trim PREFIX , but what does || '-' || mean here? My understanding for line 3 is after finishing the trim function in line 2, do another trim, but I do not recognize the syntax in line 3 either . This is DB2. RETURN CASE WHEN PREFIX BETWEEN '00' AND '99' //line 1 THEN TRIM(PREFIX) || '-' || //line 2 TRIM

问题 I have some Oracle-tables where some of the PK-fields are defined as CHAR(9), and all values are stored with padding. Thus, I have to retrieve all objects with space-padding in the key-fields.

Since this occurs on the ID-values, there is no way for me to use @PostLoad in order to 'fix' the key so it will contain the spaces. I have no way of deleting/updating the object since the key-value is changed to a

问题 I have an Excel spreadsheet with several cells that have leading or trailing whitespace (including spaces, non-breaking spaces, carriage returns, and new lines). I want to remove these white spaces. My Google searching suggests this can only be done with VBA. The VBA Trim function doesn't remove all types of whitespaces and may remove from the middle of the cell as well. The MSDN page for VBA's Trim function references .NET's String.Trim method which does exactly what I want. However, I'm not
