informix

问题 I am trying to figure out how to connect to an IBM informix database. I have been doing some research and have found some threads from 5 years ago but those examples are not working. I have installed the latest SDK from IBM for informix. I have included the IBM.Data.Informix.dll to my references in my project. I have included the using IBM.Data.Informix; I am just adding a button and on click testing the conenction. I always get this debug error "SQL0035N The file "C:\Users\Adam\documents

问题 I need to create an Informix procedure to return a table with rows if I found some value and an empty table if no value found. I know how to return a table with rows, but I don't know how to return the empty table; can anyone help? CREATE row type AType ( id VARCHAR(255), name VARCHAR(255) ); CREATE PROCEDURE getmeasurement (p_date DATETIME YEAR TO SECOND) RETURNING MULTISET(AType NOT NULL); DEFINE AType_TABLE MULTISET (AType NOT NULL); DEFINE v_id VARCHAR(255); DEFINE v_name VARCHAR(255); ..

问题 ISQL-SE 4.10.DD6 (DOS 6.22): My app has the following SQL script (CODE REVIEW) which my users exec at end of business day to reorg the transaction table: DATABASE dbfiles; UNLOAD TO "U:\UNL\ACTIVES.UNL" SELECT * FROM transaction WHERE trx_type IN ("E","I","C","P") ORDER BY trx_cust_fullname, trx_last_pymt; UNLOAD TO "U:\UNL\INACTIVES.UNL" SELECT * FROM transaction WHERE trx_type IN ("F","R","T","X","V") ORDER BY trx_cust_fullname, trx_last_pymt DESC; DROP TABLE transaction; CREATE TABLE

问题 I'd need some advice how to handle transactions with Informix CSDK and OIC++. conn is a open connection object. Select works find. The database here is setup with logging — as I found out while update stmt on its own does nothing. Here's what I tried: conn.SetTransaction( ITConnection::BEGIN ); qtext = "UPDATE transit_kunde_s SET erledigt='Y' WHERE transitkunde='"+ts+"'"; cout << qtext << endl; code = query_up.ExecForStatus(qtext.c_str()); cout << "code " << code << endl; conn.SetTransaction(

问题 I have some queries written in Informix-style SQL. Specifically, this query selects the items in a customer's order. (I've simplified the table structure somewhat, though I kept the part that is problematic.) SELECT ordi.line_no, ordi.item_code, ordi.desc, ordi.price, shpi.location, shpi.status, shpi.ship_code, box.box_no, box.tracking_no, shpc.ship_co, mfr.mfr_name, sum(shpi.ship_qty), sum(shpi.net_cost) FROM order_items ordi, ship_items shpi, OUTER ship_boxes box, shipping_companies shpc,

问题 With functionality from the RODBC package, I have successfully created an ODBC but receive error messages when I try to query the database. I am using the INFORMIX 3.31 32 bit driver (version 3.31.00.10287). channel <- odbcConnect("exampleDSN") unclass(channel) [1] 3 attr(,"connection.string") [1] "DSN=exampleDSN;UID=user;PWD=****;DB=exampleDB;HOST=exampleHOST;SRVR=exampleSRVR;SERV=exampleSERV;PRO=onsoctcp ...

问题 I would like to change a couple of column values before they get inserted. I am using Informix as database. I have a table consisting of 3 columns: Name (NVARCHAR), Type (INT), Plan (NVARCHAR). Every time a new record is inserted, I would like to check the Name value before inserting it. If the Name starts with an F, I would like to set the Type value to 1 and the Plan Name to "Test" In short, what I want the trigger to do is: For every new insertion, first check if Name value starts with F.

问题 I have a statement that needs writing (with generic names for stuff, since this is for work) to update a column 'updCol' in table 'tUpd'. tUpd also has a column 'linkCol' which is present in another table tOther. tOther has another column 'idCol'. My problem is to update the updCol value of rows in tUpd which correspond via linkCol to rows with a given idCol value. One solution I think should work is the following; update tUpd set updCol = XXX where exists ( select idCol from tOther where

问题 I'm running the below query against an IBM Informix database and getting an ERROR 42000: A syntax error has occurred . The FROM and WHERE clauses run fine in other queries, so I'm looking at the SELECT and GROUP BY portions. Any ideas what's wrong with the syntax? SELECT COUNT(DISTINCT "informix".agentconnectiondetail.sessionid) AS calls_abandoned, DAY("informix".agentconnectiondetail.startdatetime) AS Expr2 FROM "informix".agentconnectiondetail, "informix".contactqueuedetail, "informix"
