Hi I am new to SQL scripts and have some problem to read below, especially for the symbols of N'USER11'and 'TV11man^%'. Could anybody interpret the statement including the symbols? Thanks a lot!
if not exists (select * from syslogins where loginname=N'USER11')
EXEC sp_addlogin 'USER11', 'TV11man^%', 'Lobby11'
If the USER11 entry does not exist, add login for USER11.
TV11man^% appears to be a password.
Normally % is a wildcard in SQL.
FYI.. Depending on your permissions, you can open the database:
select Programmability/Stored Procedures/System Stored Procedures
Locate sp_addlogin
Right-Click and choose modify
You will see what parameters are needed and what they mean,

I've successfully connected to a IBM DB2 database in SPSS using the connection wizard. However, I haven't found a working method to do this using SPSS syntax. Has anyone any experience with this?
Normally you'd access it via this Syntax:
GET DATA /TYPE = - insert one of these types - ODBC,OLEDB,XLS,XLSX,XLSM,TXT
Whichever is the type that you wish to access, you can also use SQL within the SPSS syntax editor. This is how I connect to my database from the syntax:
GET DATA
/TYPE=ODBC
/CONNECT='DSN=MAVSQL;Description=SQL;UID=;APP=IBM SPSS Products: Statistics '+
'Common;WSID=MAVNEW;DATABASE=Players;Trusted_Connection=Yes'
/SQL='SELECT Id, Faction, Active, Level, Name, Allignment, CurQuest, '+
'PrevQuest, DeathCount, LastDeath, LastLogon, Created, Class, RacAB, '+ 'Comments, Test, Age, RealName, Email FROM dbo.DSOL'
/ASSUMEDSTRWIDTH=255.
CACHE.
EXECUTE.
DATASET NAME DataSet1 WINDOW=FRONT.
Hope that helps, I know the database I accessed is a SQL database but perhaps you can use the same methodology to access your IBM DB2 database.
Besides pasting the syntax shown in the last panel of the Database Wizard, which includes the connection string and the SQL that goes with the GET DATA command, you can save the query as an spq file from that last panel and use that again in the Database Wizard by choosing Edit Query in the first step.
I'm new at working on an as400 and I have a query the joins across 4 tables. The query itself is fine, it runs in STRSQL and displays the results.
What I am in struggling with is getting the query to be able to run programmatically (it will eventually be run from a scheduled CL script).
I tried have creating a physical file that contains the query running it with RUNQRY, but it simply displays the query itself, not the actual result set.
Does anyone know what I am doing wrong?
UPDATE
Thanks everyone for the direction and the resources, with them I was able to reach my goal. In case it helps anyone, this is what I ended up doing (all of this was done in it's own library, ALLOCATE):
Created a source physical file (using CRTSRCPF): QSQLSRC, and created a member named SQLLEAGSEA, with the type of TXT, that contains the SQL statement.
Created another source physical file: QCLSRC, and created a member named POPLEAGSEA, with the type of CLP, that changes the current library to ALLOCATE then runs the query using RUNSQLSTM (more detail on this below). Here is the actual command:
RUNSQLSTM SRCFILE(QSQLSRC) SRCMBR(SQLLEAGSEA) COMMIT(*NONE) NAMING(*SYS)
Added the CLP to the scheduled jobs (using ADDJOBSCDE), running the following command:
CALL PGM(ALLOCATE/POPLEAGSEA)
With regard to RUNSQLSTM, my research indicated that I wasn't going to be able to use this function, because it didn't support SELECT statements. What I didn't indicate in my question was what I needed to do with the the result - I was going to be inserting the resultant data into another table (had I done that I'm sure the help could have figured that out a lot quicker). So effectively, I wasn't going to be doing an SELECT, my end result is actually an INSERT. So my SQL statement (in SQLLEAGSEA) begins with:
INSERT INTO
ALLOCATE/LEAGSEAS
SELECT
...
BLAH BLAH BLAH
...
From my research, I gather that RUNSQLSTM doesn't support SELECT because it doesn't have a mechanism to do anything with the results. Once I stopped taking baby steps and realized I needed to SELECT AND INSERT in the same statement, it solved my main problem.
Thanks again everyone!
The command is RUNSQLSTM to run a static SQL statement in a physical file member or stream file.
It is a non-interactive command so it will not execute sql statements that attempt to return a result set.
If you want more control, including the ability to run interactive statements, see the Qshell db2 utility.
For example:
QSH CMD('db2 -f /QSYS.LIB/MYLIB.LIB/MYSRCFILE.FILE/MYSQL.MBR')
Note that the db2 utility only accepts the *SQL naming convention.
QM Query
If all the SQL you need is the single complex SQL statement, and this is what it sounds like, then your best bet is to use Query Management Query (see QM Query manual here).
The results can be directed to a display, a spool file, or a physical file (ie a DB2 table). The default output when run interactively is to the screen, but when run in a (scheduled) batch job it will default to a spool file report.
You can create the QM Query interactively via WRKQMQRY, in prompted mode (much like Query/400) or in SQL mode. Or you can compile the QM Query from source, with the CRTQMQRY command.
To run your QM Query, STRQMQRY command.
RUNSQL cmd
If you are using a system that has IBM i 7.1 fully up-to-date, and has Technology Refresh 4 (TR4) installed, then you could also use the new RUNSQL command to execute a single statement. (see discussion in developerWorks)
SQL Scripting w/ RUNSQLSTM cmd
From CL you can run SQL scripts of multiple SQL statements from a source file member. There is no standard default source file name for this, but QSQLSRC is commonly used. The source member can contain multiple non-interactive SQL statements. This means you cannot use a SELECT statement (directly) since theoretically it will not know where to send the results. CL commands are even allowed if given a CL: prefix. Both SQL and CL statements should be terminated with a semicolon ;. While the SQL statements cannot display data directly to the screen, the same restriction does not apply to the scripted CL commands.
The STRQMQRY command can be embedded in the RUNSQLSTM script, by placing the prefix "CL: " in front of the command. Since STRQMQRY can direct output to the screen, a report, or an output table, this can come in very useful.
Remember that to direct your output from a SELECT query to a file you can use either the INSERT or CREATE TABLE statements.
CREATE TABLE newtbl AS
( full-select )
WITH DATA;
Or, to put the results into a table you create in your job's QTEMP library:
DECLARE GLOBAL TEMPORARY TABLE AS
( full-select )
WITH DATA;
[Note: If you create the source to be used by CRTQMQRY, you are advised to create it as CRTSRCPF yourlib/QQMQRYSRC RCDLEN(91), since the compiler will only use 79 columns of your source data (adding 12 for sequence and change date =91). However for QM Forms, which can be used to provide additional formatting, the CRTQMFORM compiler will use 81 columns so RCDLEN(93) is advised for QQMFORMSRC.]
RUNQRY is a utility that lets you execute a query that was created by another utility named WRKQRY. If you really want to process SQL statements held in a file try RUNSQLSTM. It uses a source physical file to store the statements, not a database file. The standard name for that source physical file is QQMQRYSRC. To create that file, CRTSRCPF yourlib/QQMQRYSRC. Then you can use PDM to work with that source PF. WRKMBRPDM yourlib/QQMQRYSRC. Use F6 to create a new source member. Make it source type TXT. Then use option 2 to will start an editor called SEU. Copy/paste your SQL statements into this editor. F3 to save the source. Once the source is saved, use RUNSQLSTM to execute it.
It is (now) possible to run SQL directly in a CL program without using QM Query, RUNSQLSTM or QShell.
Here is an article that discusses the RUNSQL statement in CL programs...
http://www.mcpressonline.com/cl/the-cl-corner-introducing-the-new-run-sql-command.html
The article contains information on what OS levels are supported as well as clear examples of several ways to use the RUNSQL statement.
This will work in two steps:
RUNSQL SQL('CREATE TABLE QTEMP/REPORT AS (SELECT +
EXTRACT_DATE , SYSTEM, ODLBNM, SUM( +
OBJSIZE_MB ) AS LIB_SIZE FROM +
ZSYSCOM/DISKRPTHST WHERE ODLBNM LIKE +
''SIS%'' GROUP BY EXTRACT_DATE, SYSTEM, +
ODLBNM ORDER BY LIB_SIZE DESC) WITH +
DATA') COMMIT(*NONE) DATFMT(*USA) DATSEP(/)
RUNQRY QRYFILE((QTEMP/REPORT)) OUTTYPE(*PRINTER) +
OUTFORM(*DETAIL) PRTDFN(*NO) PRTDEV(*PRINT)
The first step creates a temporary table result in qtemp and the second step/line runs an adhoc query over just the temporary table to a spool file.
Thanks,

There is of course a totally different solution: You could write and compile a program containing the statement. It requires some longer reading into, especially if you are new to the platform, but it should give you most flexibility over what you do with results. You can use SQL in C, C++, RPG, RPG/LE, REXX, PL (of which I don't know, what it is) and COBOL. Doing that, you can react in any processable way on results from one query and start/create other queries based on what you get.
Although some oldfashioned RPG-programmers try everything to deny SQL in RPG exists, it is possible today for many cases, to write RPG-programs with SQL only and no direct file access (without F-Specs, for those who know RPG).
If your solution works for you, perfect. If you need to do something else, try a look into this pdf: http://publib.boulder.ibm.com/infocenter/iseries/v5r3/topic/rzajp/rzajp.pdf
The integration into RPG is not too bad. It works with the normal program flow. Would look something like this (in free form):
/free
// init search values:
searchval = 'Someguy';
// so the sql query:
exec sql
SELECT colum1, colum2
INTO :var1, :var2
FROM somelib/somefile
WHERE keycol=:searchval;
// now do something with the values:
some_proc(var1);
/end-free
In this, var1, var2, and searchval are ordinary RPG-variables. No quoting needed. Works also with datastructures (externally defined e.g., the record format of the file itself fits well). You can work with cursors and loops, too, of course. I feel that RPG-programs tend to be easier to read with this.
Im trying to run the following to import a large volume of sales data in a text file into a database. When i run the following i get the error: "Invalid object name 'PetDatabase.Sales'
BULK INSERT PetDatabase.Sales
FROM 'C:\Temp\P1.txt'
WITH
(
FORMATFILE = 'C:\Temp\PetSales.Fmt'
);
Can anyone see whats causing my problem? I do have the tables within a folder; however, when i tried PetsDatabase.Tables.Sales it made no difference.
Ignore this answer. It was written when the question was tagged with mysql. Leaving the answer here to keep the comments.

Try using LOAD DATA INFILE instead.
http://dev.mysql.com/doc/refman/5.1/en/load-data.html
Make sure PetDatabase.Sales exists in your text file.
Swap for whichever row and field terminator delimiters you're using. Here I'm using delimiters from a comma separated file
BULK INSERT PetDatabase
FROM 'c:\temp\p1.txt'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
)
GO
--Check the content of the table.
SELECT *
FROM PetDatabase
GO
--Drop the table to clean up database.
SELECT *
FROM PetDatabase
GO
Also, make sure the following doesn't apply to you:
If a SQL Server user is logged in using Windows Authentication, the user can read only the files accessible to the user account, independent of the security profile of the SQL Server process.
When executing the BULK INSERT statement by using sqlcmd or osql, from one computer, inserting data into SQL Server on a second computer, and specifying a data_file on third computer by using a UNC path, you may receive a 4861 error.
To resolve this error, use SQL Server Authentication and specify a SQL Server login that uses the security profile of the SQL Server process account, or configure Windows to enable security account delegation.
Is PetDatabase is schema name or database name?
If it is database name, then include schema name also like this if your schema name is dbo.
PetDatabase.dbo.Sales
I would like to run some ad hoc select statements in the IBM System I Navigator tool for DB2 using a variable that I declare.
For example, in the SQL Server world I would easily do this in the SQL Server Management Studio query window like so:
DECLARE #VariableName varchar(50);
SET #VariableName = 'blah blah';
select * from TableName where Column = #VariableName;
How can I do something similar in the IBM System I Navigator tool?
I ran across this post while searching for the same question. My coworker provided the answer. It is indeed possible to declare variables in an ad hoc SQL statement in Navigator. This is how it is done:
CREATE OR REPLACE VARIABLE variableName VARCHAR(50);
SET variableName = 'blah';
SELECT * FROM table WHERE column = variableName;
DROP VARIABLE variableName;
If you don't drop the variable name it will hang around until who knows when...
At the moment, we're working on the same issue at work. Unfortunaly, we concluded that this is not possible. I agree, it would be great but it just doesn't work that way. iNavigator doesn't support SET or Define. You can do that in embedded SQL but this is not embedded SQL. Even if you create a separate document (xxx.sql), then need to open this document to run the script what makes it an interactive script (that is, DECLARE SECTION is not allowed).
As an alternative, in the SQL screen/script you can use CL:. Anything after this prefix is executed as CL command. You may manipulate your tables (e.g. RNMF) this way.
As a second alternative, the iSeries does support Rexx scripts (default installed with the os). Rexx is good dynamic script language and it does support embedded SQL. I've done that a lot of times and it works great. I even created scripts for our production environment.
Just create one 'default' script with an example PREPARE and CURSOR statement and copy at will. With that script you can play around. See the Rexx manual for the correct syntax of exec-sql. Also, you do have STDIN and STDOUT but you can use 'OVRDBF' to point to a database table (physical file). Just let me know if you need an example Rexx script.
Notice that the manual "SQL embedded programming" does have Rexx examples.
Here are a couple of other alternatives.
Data Transfer Tool - You can run the iSeries Data Transfer Tool from the command line (RTOPCB). First, run the GUI version and create a definition file. If you edit this file with a text editor, you will see that this is just an old-fashioned INI file and you can easily find the line with the query in it. From there, you could write a batch file or otherwise pre-process the text file to allow you to manipulate the query before submitting it to the query tool.
QSHELL - If you can log on to the iSeries interactively, then you may find the QSHELL environment more familiar than CL or REXX (although REXX is kind of fun). QSHELL is a full POSIX environment running on the iSeries. Use the command STRQSH to start QSHELL. You can have ksh or csh as a shell. Inside QSHELL, there is a command called "db2" that submits queries. So, you should be able to do something like this inside QSHELL:
system> VariableName = 'blah blah'
system> db2 "select * from TableName where Column = \'$VariableName\'"
You may have to fiddle with the quotes to get ksh to pass them correctly.
Also, inside QSHELL, you should have a full Perl installation that will allow you to use DBI to get data.
Some other ways to interact with data on the iSeries: query from the client with Python via ODBC; query from the client with Jython via JDBC; install Jython directly on the iSeries and then query via JDBC.
I am trying to archive some of my tables into another database on the same server. However the INSERT INTO...SELECT...FROM gives me an error (SQLSTATE=42704) on build. The table exists in the second database.
Can anyone help with this?
It's not clear from your question what version of DB2 is being used. I'll presume that it's the Linux, Unix & Windows version. You look to be using federation to link the two databases.
Does the SELECT part of your query work from LS2DB001? It's worth trying to pin down which database you have the issue with.
Presuming that the problem is on LS2DB001, if the user you have defined the federated link with has permissions on the base tables in the query, check also that they have permissions on the system catalog tables. If not, they would not be able to parse and validate that you can run the query.
We've cracked it! If the following script is used then it works. The LOAD works without having to COMMIT in between batches of rows copied. ('Transaction Log full...' error problem is also solved)
CONNECT TO LS2DB001;
EXPORT TO "C:\temp\TIN_TRIGGER_OUT.IXF" OF IXF
MESSAGES "C:\temp\TIN_TRIGGER_OUT.EXM"
SELECT * FROM LS2USER.TIN_TRIGGER_OUT;
CONNECT RESET;
CONNECT TO LQIFCOLD;
LOAD FROM "C:\temp\TIN_TRIGGER_OUT.IXF" OF IXF
MESSAGES "C:\temp\TIN_TRIGGER_OUT.IMM"
INSERT INTO LS2USER.TIN_TRIGGER_OUT COPY NO INDEXING MODE AUTOSELECT;
COMMIT;
CONNECT RESET;
I found this on http://www.connx.com/products/connx/Connx%208.6%20UserGuide/CONNXCDD32D/DB2_SQL_States.htm:
42704 Undefined object or constraint name. Revise SQL syntax and retry.
For more help try to be more specific, eg paste the full sql statement, the table scheme etc.
You can do
Select 'insert into tblxxxx (blabla,blabal) values(' + fld1 + ',' + fld2 + ',' ...... + ')'
From tblxxxxxx
copy the result as a text script and execute it in the other DB.
The best way to do this would be to create a custom script. Depending on the size of the tables (how many records) you could either do a select of all of the data into memory and then roll over them inserting them into a copy of the table you create first, or you could export the data out as a csv file or some other text based file and then roll over that to insert the data into the other table.
If you do not have some sort of formal backup procedures that could do this already, this would be your best bet.
Note: some db2 databases, such as those on an iSeries do not actually have "databases", they have libraries. With the right user profile you can access two libraries at the same time, joining tables from them together or doing a
create table library/newFilename as
(select * from originallibrary/originalfilename) with data
But this only applies to the iSeries I believe.
I'm writing this response as another answer so I have more space.
I can only suggest breaking the steps down to their components, and working through to see where the error is occuring. Again, I'm assuming you're using federation:
a) In your FROM db, connecting as the user you're using for the federated link, does your select work?
b) In your TO db, using the link, does the select work?
c) In your TO db, using the link via a stored proc, does the select work?
d) In your TO db, using an INSERT...values(x,y,z), can you insert into the table?
e) In your TO db, via a stored proc, using INSERT...values(x,y,z), can you insert?
Without more information, this is the best line of attack I can suggest.
