Generating SQL SELECT statement with Schema
I develop a 3rd-party application that connects to various
databases via ODBC. Our program generates the SQL statement
so that the user does not have to. When connecting to oracle the
user often gets the error message: ORA-00942: table or view does
not exist.
To work around this our tech support department has tells the
customer to enter in the Schema name before the table name.
Thus,
SELECT ItemNo from Item
becomes
SELECT ItemNo from MySchema.Item
Is there a way that I can query the Data Source to find out
the Schema name so that our program can put in in the
statement. Is there a SQLGetInfo call I can make to get
this information?
Or, should I have the Server specified in the connection
string? For SQL Server we use SQLGetPrivateProfileString to
obtain the server name and then include it in the connection
string: SRVR=<servername>
Unfortunately, if this is the case the keyword is different
depending on the ODBC Driver involved. "Server" for Microsoft.
"SRVR" for Intersolv. "ServerName" for Oracle.
Note: We do not have Oracle in-house to test with. I'm
wondering if we could get Oracle for free for development
purposes.
Any and all information would be greatly appreciated.
Thanks for the tip. I just finished downloading Oracle.
One user is able to successfully view the database with the
statement:
SELECT ItemNo from Item
But if another user tries it he gets the "table or view not
found" message. Changing the statement as follows will allow
the 2nd user to view the database:
SELECT ItemNo from "MAXIMO".Item
I want my application to query the database via ODBC for the
"MAXIMO" string so I can create the correct SQL statement.
Thanks!
<<Are you trying to view tables from a non-default schema?>>I don't know. You would know better than me from my
description.

Exporting SQL Select statement to spreadsheet
Hi all, basic question that I couldn't find the answer to while googling and searching the Oracle documentation.
What is the code for exporting the result of a SQL Select statement to a spreadsheet such as Excel or Calc? In Oracle SQL Developer I tried saving the output as an XML file but it did not come out properly and I tried using EXPORT at the end of the statement but it gave an error message and I am not sure if this is the right command or what the syntax is.

SmileySeems like you want to convert a SQL statement from the ??? dialect to the Oracle dialect. *(It would be useful to indicate the non-ANSI standard SQL you are starting with.)
Part of the problem is that you use several date related functions. Some are unnecessary in Oracle and some need to translated into Oracle functions as found in the Functions section (chapter 5) of the SQL Reference manual at http://www.oracle.com/pls/db102/homepage
Note that columns and expressions of type 'date' in ORacle always contain all of "yyyy mm dd hh mi ss" and you need to format and trauncate as necessary.
Also note that '09-JAN-31' is NOT an Oracle date, but rather a character representation of a date which must be converted to/from a date expression. You will often need to use the to_date() and to_char() functions with a format mask as the second parameter. This is also descreibed in the first 2 chapters of the SQL Reference manual. -
I use LV7.1.1 to read/update an Access Database, using DB Toolset.
When I use the Sql 'SELECT' query with LIKE operator, I do not get any results. (no error is returned).
The statement is:
SELECT Machine, System, AD, Query_Position, RefDesignator, Description
FROM AllLevel
WHERE ((Machine LIKE '*') AND (System LIKE '*') AND (AD ='2000CV20012') AND (Query_Position ='AD') AND (RefDesignator='u1'))
It seems that the LIKE '*' is not translated well by the 'Microsoft Jet 4.0 OLE DB Provider'. I must mention that the statement works just fine under Access, not using LV.
Is there any alternative format for LIKE '*' that do the job?
Regards,
Joseph MosheMaybe Access has different syntax, but for T-SQL, the proper syntax for LIKE is to use the % character to match any string of zero or more characters and the _ character to match a single characer. In fact, the documentation says that while * and ? are understood,
"The % and _ (underscore) wildcard characters should be used only
through the Jet OLE DB provider and ActiveX® Data Objects (ADO) code.
They will be treated as literal characters if they are used though the
Access SQL View user interface or Data Access Objects (DAO) code." -
Javascript and sql select statement
I am working in html db in the 10 g environment. I'm trying to create an "auto suggestion function" that predicts values as the user enters characters into a text field. I've gotten it to work by hard coding the values in the function, ie: states. btw: there are several external javascript files at work here.
What I want is to create a dynamic link to the database to gather, say, all names of providers at the time the page is built to use in the auto suggest format. I want to put this into a javascript routine and I'm having problems finding out how to mix the sql select statement into the javascript function.
For the states example, I'm using:
function StateSuggestions() {
this.states = [
"Alabama", "Alaska", "Arizona", "Arkansas",
"California", "Colorado", "Connecticut",..."Wyoming" ];
Can I substitute the hard coded data (states) with a sql select statement such
as:
select name from <dbtable> ???
How does this need to be "wrapped" or containerized?
Thank you. You have a great product in html db and your site is very useful. I appreciate everything you have done to assist us. Again, thank you.Hi,
You can use TRUNC with 2 arguments to get the first DATE in a month, year, quarter, week, hour, minute, ISO year, ...
SELECT TRUNC ( ADD_MONTHS ( SYSDATE
, 12
, 'MONTH'
) AS first_of_month
FROM dual
;The DATE returned will be in the same month, year, quearter, ... as the first argument.
\We convered the last day of the month in [your previous question|http://forums.oracle.com/forums/message.jspa?messageID=3942939#3942939].
At that time, I warded about using LAST_DAY as a cutoff point; TRUNC is a much better way.
For example, to find all appointment_dates in the current month next year:
SELECT *
FROM appointments
WHERE appointment_date >= TRUNC (ADD_MONTHS (SYSDATE, 12), 'MONTH')
AND appointment_date < TRUNC (ADD_MONTHS (SYSDATE, 13), 'MONTH')Note that
the first part of the WHERE clause calls for dates on or equal to the beginning of the 12th month in the future, but
the second part of the WHERE clause calls for dates before, not equal to , the beginning of the 13th month in the future. -

DharmarajuHi, Dharma Raju Kondeti.
I found this in the SAP online help, hope this can help you.
Specifying Internal Tables
When you read several lines of a database table, you can place them in an internal table. To do this, use the following in the INTO clause:
SELECT ... INTO|APPENDING [CORRESPONDING FIELDS OF] TABLE <itab>
[PACKAGE SIZE <n>] ...
The same applies to the line type of <itab>, the way in which the data for a line of the database table are assigned to a table line, and the CORRESPONDING FIELDS addition as for flat work areas (see above).
The internal table is filled with all of the lines of the selection. When you use INTO, all existing lines in the table are deleted. When you use APPENDING; the new lines are added to the existing internal table <itab>. With APPENDING, the system adds the lines to the internal table appropriately for the table type. Fields in the internal table not affected by the selection are filled with initial values.
If you use the PACKAGE SIZE addition, the lines of the selection are not written into the internal table at once, but in packets. You can define packets of <n> lines that are written one after the other into the internal table. If you use INTO, each packet replaces the preceding one. If you use APPENDING, the packets are inserted one after the other. This is only possible in a loop that ends with ENDSELECT. Outside the SELECT loop, the contents of the internal table are undetermined. You must process the selected lines within the loop.

feng.

Parsing an OPEN SQL select statement
Hi all,
I want to parse an open SQL select statement to get the list of tables and the corresponding fields in the select statement.
Is there some ABAP-internal syntax from the SAP Database Interface that does this? or is the only option to do this is to manually break the statement?
Thanks.
GirishHi,
I doubt if there is something like that available to use. It think you will have to write a parser for yourself.

Retrieve floating point data with an sql select statement
Hi
I'm quite new to using sql but I have a system working where I can read and write strings to an access database.
Now I want to retrieve a a float, from a field where another field in the same post corresponds to a specified float, with a select statement.
When using strings I wrote
SELECT column_name FROM [table_name] WHERE column2_name='value'
in my query.
But instead of getting the desired value I get an error message telling me that I have a
"Data type mismatch in criteria expression".
I think I understand why but does anybody know what I should have written instead?Is the data type of column2_name String? If it's not, I think the single-quotes you have around 'value' will cause that error.

How to generate mutiple Results for multiple SQL SELECT statements
I just downloaded SQL Developer 1.5 and play around with it.
On a daily basis, I need run 4 different SELECT statements and dump the output of each SELECT into an CSV file and send to some users. In SQL Navigator, I can select all 4 SELECT statements and execute them at same time. Once all complete, I will see 4 tabs, each represent the output for each SELECT statement. Then I can export output from each tab into a CSV file.
It seems that SQL Developer 1.5 still can't run mutiple SELECT statements and display the output of each statement into a separate "Results" tab so that I can export the data into multiple CSV files easily.
Right now, I have to hightlight each SELECT statement and press F9, then export the output data into CSV.
I wish I can execute 4 SELECT statements all in once on SQL Developer and get all the output data and export 4 times into 4 CSV files.
Thanks!
KevinHow about doing it as a set of tabs within the Resuls Tab?
So you would have your Top row of tabs:
Results, Script Output, Explain, AutoTrace, DBMS Output and OWA Output
Then When you have the Results tab selected you could have a row of tabs beneath the Top row with one tab for each result set. Switching between result sets should switch which section of SQL is highlighted as the "Current SQL".
A similar mechinism could be employed for each of the top level tabs where it makes sense to have multiple output tabs.
A further refinement of this feature might be to allow the result tabs to be dockable within the parent tab so that multiple result tabs can be viewed simultaneously. This way 2 or more explain plans (for example) could be visually compared without requiring the code to exist in two separate code panes. -
Problem with writing SQL Select statement.

You should not create any function to get this output. It should be a Select statement. You can use 8i features. You can exclude the comma between the values instead of that you can put spaces. No hard coding.
Thank you in advance.

How to use a select statement with chinese characters?
I am currently developing a java servlet<using tomcat 4.x> which allows me to use select statement to retrieve results from the Microsoft SQL Server 2000 database. I am using a simple form to get the parameter for querying. The main problem i'm facing is that there are chinese information in the SQL database, but i can't retrieve it through the sql statement with the chinese characters input<thru the form with the help of NJ STAR>in the WHERE condition. When i execute the statement, it returns me no results even though the rows are present in the database.
Does anyone have the solution to using chinese words in the WHERE clause of the select statement to retrieve results with columns which contains chinese characters? Please help me. Thanks everyone. :)
PS: when i cut and paste those characters in the sql database and paste onto java.. it is ??? in questionmarks.. but when i paste them into excel 2000.. its shown as chinese chars again..
please heelppp~~Greetings,

You need to set the character encoding set on your
statement and parameters for the characters to be
properly translated. Refer to the charsetName
parameter in the String class constructor in your API
docs and also to
$JDK_DOCS/guide/intl/encoding.doc.html in your JDK
documentation.
2000.. its shown as chinese chars again..Because Office programs are performing the same kind
of character translation with the appropriate MS APIs.
please heelppp~~Regards,
Tony "Vee Schade" Cookis it possible for you to show me some coding examples? i don't really understand what is to be done in order to set the char set and what does it really do.. tried reading up but still dun understand.. :(
pardon my shallow knowledge of java..
ok..
The thing is when i used an insert statement with chinese characters of GBK format hardcoded into the java servlet and then i use the insert statement to insert the chars into the database, it cannot be seen as a chinese word when i off the NJStar. and then it can be searched out with my current form of servlet.. below is my coding of the servlet..
note: i've set my html file to charset = GBK

with the above servlet i created, i can search out the data in the database which i've inserted through the insert statement. I still can't search for things i've keyed into the database directly using NJStar..
thank you so much for helping.. really hope any one else who knows the answer to this will reply too... thank you all so much...
