问题 I have a query that makes joins between 4 tables. Matching my input params on a table by table basis yeilds the following TrialBal - 8 million records matching entity and pl_date Join to ActDetail - Execution is about 85 secs, the row count is 8672175 (with group by, the row count is 1...for now). ActDetail would return zero rows on an inner join. Join to CalendarEngine - there are only 60 matchig records in this table (pl_date & entity), but when this is introduced to the SQL, the query just

问题 I am working on Sybase Adaptive Server Enterprise (version 12.5.0.3). Trying to use Row_number() OVER (Partition by columnname order by columnname) . When I execute the query it is throwing an exception saying that the syntax near OVER is incorrect. I have searched for proper row_number() syntax for sybase database, but there is nothing wrong in the syntax. I guess that the Sybase version that am using does not support row_number() OVER . I even tried dense_rank() OVER , but am getting the

问题 I have a linux box. When I had a Windows box, I was able to download the free non-commericial use MS SQL Server. How can I run free personal copies of SQL Server, Sybase, or Oracle on my linux box? I don't need to to have any permanent databases or any great amount of storage. I just want to (re-)familiarize myself with these different SQL dialects, and compare techniques and timing to the MySQL and postgresql I do have installed. Thanks. 回答1: SQL Server does not run on Linux. MySQL, however,

问题 I have rows of data with a begin date and end date that are usually from the start of the month until the end of that month. However at times there are rows that are either - several months long - start in the middle of a month and end either the same month or a future month - begin at start of a month, but end somewhere int he middle of a future month. i need to break these date ranges by month, but do not know how to go about this. any guidance is appreciated. thanks, 回答1: You could use a

问题 I have DBA authority to a sybase database on Windows. I have a another user that I don't know the password for. I regularly use an application that does know the password, and it uses the password to automatically login to the application. However, I can't find a way to find that password anywhere in the application or its dlls/files/registry/etc. I obviously don't want to just change the password of the user, as the password in the application can't be updated (that i know of). I want to be

问题 This is similar to CHECK CONSTRAINT of string to contain only digits. (Oracle SQL) but I want to do this for Sybase. I have a character column 'colExp' (8 characters). I want to put a check constraint to make sure values for this column are all digits. How can I do this? This will work but its not elegant colExp LIKE '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]' 回答1: It hurts the brain, not NOT LIKE (not range) works. SELECT 1 WHERE 'foo' NOT LIKE '%[^0-9]%' SELECT 1 WHERE '123' NOT LIKE '%[^0-9

问题 I am working with some data I obtained that is read with a program using an embedded Advantage Database Server. The program was not written by me and does not have all of the functionality that I need. I would like to convert this data to a different format so that I can work with it more freely, such as MySQL. I know that Sybase provides some tools for converting a single local database into SQL, which is very nice. This would work fine, except that the authors of this program create a new
