db2

问题 I have a series of calculation times in a DB2 SQL DB that are stored as float with a default value of 0.0. The table being updated is as follows: CREATE TABLE MY_CALC_DATA_TABLE ( CALCDATE TIMESTAMP, INDIV_CALC_DURATION_IN_S FLOAT WITH DEFAULT 0.0, CALC_TIME_PERCENTAGE FLOAT WITH DEFAULT 0.0 ) Using a sproc. I am calculating the sum as follows: CREATE OR REPLACE PROCEDURE MY_SCHEMA.MY_SPROC (IN P_DATE TIMESTAMP) LANGUAGE SQL NO EXTERNAL ACTION BEGIN DECLARE V_TOTAL_CALC_TIME_IN_S FLOAT

问题 As soon as I've solved one issue with IBM.EntityFrameworkCore, another one has arose. Everything is soooo hard and painful with DB2 and their .NET team... The problem: I have several EntityFrameworkCore - based projects in the same VS solution, for example MyDb2EfModel , MyMsSqlEfModel , and MyNpgsqlEfModel . (It's kind of a complex data-integration scenario.) On top of that I have a CLI project which references all the three and performs actual data ops. When the CLI project references only

问题 I need to copy, on a daily basis, a very large (millions of rows) table from one DB2 DB to another, and I need to use perl and DBI. Is there a faster way to do this than to simply fetchrow_array each row from the first DB and insert them one-by-one into the second DB? Here's what I got: $sth1 = $udb1 -> prepare($read_query); $sth1 -> execute(); $sth1 -> bind_columns(\(@row{@{$sth1 -> {NAME_1c}}})); $sth2 = $udb2 -> prepare($write_query); while ($sth1 -> fetchrow_arrayref) { $sth2 -> execute(

问题 I am trying to restore a DB2 backup file into my BlueMix DashDB service. How do I go about doing this? 回答1: You cannot restore your DB2 backup image into dashDB for several reasons. In an entry-level, shared dashDB instance you only have access to one schema in a physical database shared by others. Even if you have a dedicated instance, you need 1) access to the database local disk to upload the image and 2) sufficient privileges (at least SYSMAINT authority) to perform the restore. I doubt

问题 I am doing a simple stored procedure call to DB2. While it calls the stored procedure, it always returns this error: DB2 SQL Error: SQLCODE=-440, SQLSTATE=42884, SQLERRMC=MEDIAN_RESULT_SET;PROCEDURE, DRIVER=3.66.46 ========== Java code: String JDBC_DRIVER = "com.ibm.db2.jcc.DB2Driver"; // STEP 2: Register JDBC driver Class.forName(JDBC_DRIVER); // STEP 3: Open a connection System.out.println("Connecting to database..."); conn = DriverManager.getConnection(DB_URL, USER, PASS); // to execute

问题 Hi I am using R to save a data frame into a DB2 SQL table. I seem to be able to create the table skeleton, but not append the data to the table - >df <- read.csv("dat.csv") where dat.csv is a csv with no headers, just raw data in two columns then i create the table: >sqlQuery(channel, "create table sqltable ( col1 int, col2 float )" ( where I confirm the table is created by being able to select the empty table "sqltable" on the database so now I need to add the data from "dat.csv" into

问题 i have problem using LIKE structure in DB2 : for example: select * from TEST where TIME LIKE '2012-03-04-%' FYI. - TIME is TIMESTAMP data type. why using LIKE with TIMESTAMPS do not work? Additional info: i want to extract data from one single day provided by user in select statement. 回答1: Just expanding on @mortb's answer, I'd either use BETWEEN or WHERE time >= '2012-03-04' AND time < '2012-03-05' The advantage of using BETWEEN or a comparison that using casts and LIKE will mean that if

问题 Is there any reason why PHP loses all locale information after connecting to DB2 with PDO? I always have to set the locale information again after a connnection. <?PHP //set locale information setlocale( LC_MONETARY,'en_US' ); //print location information print_r(localeconv()); // Array // ( // [decimal_point] => . // [thousands_sep] => // [int_curr_symbol] => USD // [currency_symbol] => $ // [mon_decimal_point] => . // [mon_thousands_sep] => , // ... // ) //**********************************

问题 I am attempting to connect to a remote DB2 using IBM Type 4 JDBC driver. Here is my configuration: Server: Windows 7 professional DB2 LUW V10.5 DB2 SVCENAME=50000 TCP/IP to communicate Client: OS/x V10.10.3 Eclipse Mars IBM DB2 Java Type 4 drivers It is my understanding that if you write the client app in Java and use the type 4—pure Java—drivers, the client doesn't have to have a client installed. The app will use DRDA to connect directly to the remote database. Here is a snippet of code

问题 I'm trying to get control of a recursive trigger over DB2 (v9.7), unfortunately IBM documentation doesn't mention a way to know at which level of recursion the current trigger call is in. I've found that there's this function on sql-server: trigger_nestlevel(), it basically does what I want (knowing the actual trigger recursive call level). so I would like to know if there is an equivalent function in DB2. 回答1: Unfortunately DB2 does NOT have any function or stored procedure for this. You can
