问题 My question is somewhat the same as Python list of String to SQL IN parameter but I have a list of integers. The python code I use is: ids = [1000032, 1000048] sql = 'SELECT CompNo, CompName, CompType FROM Component WHERE DeptID IN (?)' cursor.execute(sql, [','.join(ids)]) And the Sybase database engine responds with: pyodbc.Error: ('07006', "[07006] [Sybase][ODBC Driver][SQL Anywhere]Cannot convert '1000032','1000048' to a numeric (-157) (SQLExecDirectW)") What is the correct way to do this?

问题 I am building a query using ODBC command object in .Net with multiple parameters being passed in. When executing the query against SQL Anywhere, I get the following error. (The same code works against SQL Server). [System.Data.Odbc.OdbcException] = {"ERROR [07002] [Sybase][ODBC Driver][SQL Anywhere]Not enough values for host variables"} The command object has the same number of parameters added as the place holders ('?') in the query. Following is a simple query and C# code that fails the

问题 I have an SQL script which creates a scheduled event: CREATE EVENT "Daily_1200PM" SCHEDULE "Daily_1200PM" START TIME '12:00' EVERY 24 HOURS HANDLER begin -- Blah blah, do some stuff here end; I would like to remove this event, if it exists. I know I can remove the event with the following: DROP EVENT "Daily_1200PM" But for some databases, the the event doesn't actually exist, so an error is thrown. How do I delete the event only if it exists? 回答1: if exists( select * from sys.sysevent where

问题 Using SQL Anywhere 16 regex (Perl 5 equivalent) I would like to match all non-digit characters in the following string: This 100 is 2 a 333 test. such that the match results in This is a test. I have a feeling this requires lookarounds but I'm not sure of the exact syntax. Some of my failed attempts: \D* matches This \D*(?=\d) matches This (\D*(?=\d*)|(?<=\d)\D*)* matches This 来源： https://stackoverflow.com/questions/36020273/regex-to-match-all-non-digit-characters-which-are-interspersed-with

问题 My customer is a dental practice that has bought a piece of practice management software. This software was installed on their local server, including a patient database, a schedule and all manner of medical records. Now they want me to write some utilities for them that aren't provided with their package, and for this I need the ability to query this database. I tried calling tech support of the software manufacturers (Patterson/EagleSoft), and it's difficult finding anyone who understands

问题 MySQL's bit_count function is quite useful for some cases: http://dev.mysql.com/doc/refman/5.5/en/bit-functions.html#function_bit-count Now I would like to use that function in other databases, that do not support it. What's the simplest way to do it (without creating a stored function, as I do not have access to the client database on a DDL level). One pretty verbose option is this (for TINYINT data types): SELECT (my_field & 1) + (my_field & 2) >> 1 + (my_field & 4) >> 2 + (my_field & 8) >>

问题 In my case, using sql anywhere (sybase). Something similar to haskell. [1..100]. I don't know how to generate a random simple list of 1 up to 100. I only could do it doing: select 1 union select 2 union select 3 Google did not provide any sample, I suspect this feature does not exist. 回答1: SQL Anywhere contains an sa_rowgenerator stored procedure, which can be used for this purpose. For example: select row_num from sa_rowgenerator( 1, 100 ) returns a result set of 100 rows from 1 to 100

问题 I created a function in PowerBuilder.NET Hello World . The project compiled as Helloworld.dll , generated in C# from the PowerBuilder utility. Inside Helloworld, I made the non-visual n_cst_helloworld . Inside the non-visual, I made the object function of_hello() . These are the issues I encountered when trying to access Helloworld.n_cst_helloworld.of_hello() in an external function on SQL Anywhere. The external function uses CLR and is called in Interactive SQL right now. Here is the script
