Calling Sybase Adaptive Server Enterprise's “sp_help” from JDBC

问题 In order to query the database meta data in Sybase ASE, I found this relevant answer (not the accepted one), to be ideal: From a Sybase Database, how I can get table description ( field names and types)? Unfortunately, I can't seem to find any documentation, how I'm supposed to call sp_help from JDBC. According to the documentation, sp_help returns several cursors / result sets. The first one contains information about the table itself, the second one about the columns, etc. When I do this:

Is there any function like REPLACE?

问题 Is there any function to replace words in ASE? 回答1: Try this: SELECT str_replace( 'impossible', 'im',':)' ) 回答2: select str_replace(original,search,replacement) ASE does not have 'REPLACE' but 'str_replace' This will return varchar(LONG), you may have use cast to shrink it back down. 回答3: REPLACE ( original-string, search-string, replace-string ) SELECT REPLACE( 'abc,def,ghi,jkl', 'abc', 'xx' ) FROM products 来源： https://stackoverflow.com/questions/6547383/is-there-any-function-like-replace

DBUnit Sybase unable to CLEAN_INSERT

阅读更多关于 DBUnit Sybase unable to CLEAN_INSERT

According to the DBUnit docs link it should support using a CLEAN_INSERT when using a DatabaseSequenceFilter. I get the following exception when attempting this com.sybase.jdbc2.jdbc.SybSQLException: Dependent foreign key constraint violation in a referential integrity constraint. dbname = 'my_db', table name = 'tbl_child', constraint name = 'fk_tbl_child_parentid'. My tables look like this: CREATE TABLE dbo.tbl_parent ( parent_id numeric(19,0) IDENTITY, ... ) CREATE TABLE dbo.tbl_child ( child_id numeric(19,0) IDENTITY, parent_id numeric(19,0) NOT NULL, ... ) ALTER TABLE dbo.tbl_child ADD

Cannot register Sybase 15 ASE OLE DB driver on Windows 7

阅读更多关于 Cannot register Sybase 15 ASE OLE DB driver on Windows 7

问题 I am trying to get the Sybase 15 ASE OLE DB driver set up on my Windows 7 machine. I already have the Adaptive Server Enterprise driver listed in the Drivers tab of my 32-bit ODBC Data Source Administrator (C:\Windows\SysWOW64\odbcad32.exe). I tried to re-register the DLL with the command regsvr32 sybdrvoledb.dll and with C:\Windows\SysWOW64\regsvr32.exe sybdrvoledb.dll from a command prompt running as admin, and in both cases I get back "DllRegisterServer in sybdrvoledb.dll succeeded" but

Windows 8 OLEDB / ADO.NET drivers for Sybase ASE?

阅读更多关于 Windows 8 OLEDB / ADO.NET drivers for Sybase ASE?

问题 Has anyone successfully installed Sybase OLEDB drivers and Sybase Central on a Windows 8 (64 bit) system? I've tried the installers on the Sybase website but they fail. Searches for "Windows 8" on the Sybase site and "Sybase Windows 8" on Google are bringing up nothing. We have a developer here who installed them on a Windows 7 system and then did an OS upgrade to Windows 8 so I know they will work. I would rather not uninstall Windows 8 and go that route if I can help it though. 回答1: I

Is there a good way to do this in SQL?

阅读更多关于 Is there a good way to do this in SQL?

问题 I am trying to solve the following problem entirely in SQL (ANSI or TSQL, in Sybase ASE 12), without relying on cursors or loop-based row-by-row processing. NOTE: I already created a solution that accomplishes the same goal in application layer (therefore please refrain from "answering" with "don't do this in SQL"), but as a matter of principle (and hopefully improved performance) I would like to know if there is an efficient (e.g. no cursors) pure SQL solution. Setup : I have a table T with

Upsert (update or insert) in Sybase ASE?

阅读更多关于 Upsert (update or insert) in Sybase ASE?

问题 I'm writing an application to move data from Oracle to Sybase and need to perform update / insert operations. In Oracle, I'd use MERGE INTO, but it doesn't seem to be available in Sybase (not in ASE, anyway). I know this can be done with multiple statements, but for a couple of reasons, I'm really trying to get this into a single statement. Any suggestions? 回答1: ASE 15.7 has this feature. Find the docs here: http://infocenter.sybase.com/help/topic/com.sybase.infocenter.dc36272.1570/html
