问题 What is the query to get a list of schemas names in a specific database in Informix? 回答1: A schema belongs to a user. You can list all available users from the sysusers system catalog : SELECT username FROM "informix".sysusers; Since only DBA s and Resource privilieges allow a user to issue a CREATE SCHEMA statement, we could restrict the query like : SELECT username FROM "informix".sysusers WHERE usertype IN ('D', 'R'); Another solution is to list only users that actually have created tables

问题 I have linked an IBM informix database table through an ODBC connection to an Access 2010 database. My issue is that the date field in this table only shows dd/mm/yy HH:nn:ss in the Access view, where the stored data is to 1000th of a second. I can show this in Excel 2010 but not in Access 2010: is this possible? Not having this level of accuracy is preventing me making accurate calculations! 回答1: There is a similar question on another forum here. The Date/Time field type in Access does not

问题 Each record could have up to 40 different person_user.description fields. Problem is, I am getting duplicate rows because records have multiple description entries. Can you help me put those additional duplicates on the same record row like: |1|badge.bid|person.first_name|person.last_name|person.type|1|2|3|4|5|etc|40| |2|badge.bid|person.first_name|person.last_name|person.type|1|2|3|4|5|etc|40| |3|badge.bid|person.first_name|person.last_name|person.type|1|2|3|4|5|etc|40| instead of this: |1

问题 I'm trying to execute a set of native SQL queries against an Informix database, using NHibernate to create the queries. However, NHibernate is set to change the query if it contains colons (they are supposedly reserved characters), and so the query fails. This is a sample of the native SQL query: CREATE PROCEDURE procedure_name() ... SELECT FIRST id :: INTEGER INTO variable ... END PROCEDURE; which NHibernate transforms into this, before executing the query, CREATE PROCEDURE procedure_name()

问题 I have troubles saving a byte array to my Informix database, I'll show you how I'm trying: In Fichero.java among other things I have this: @Column(name="fichero", columnDefinition="blob") private byte[] contenido; I had to do that way because I can't get Informix+Hibernate to accept @Lob annotation (yes, I tried that extending Hibernate's dialect workaround but it doesn't work for me) Then I read a file and convert it to a bytearray this way: FileManager.java private byte[] fromFile2ByteArray

问题 We have Informix running on our Solaris server and under /usr/informix/bin there are several executables, such as 'dbaccess' and 'isql' . Each of them produce different version information when typing 'isql -V' for example. How do you identify the exact version of the SE running? Output: 'esql -V' INFORMIX-ESQL Version 6.00.UH1 'isql -V' INFORMIX-SQL Version 6.03.UC1 'dbaccess -V' DB-Access Version 7.13.UC1 Then in /usr/informix/release directory there is a file named "SE_7.1". So is it
