I'm trying to find a column in a very big table in ORACLE SQL Developer, its really difficult to find it visually.
Is there any easy way to find the column in the table?
For example, in DBeaver its just Tab and then Ctrl + f
Oracle has an awesome data dictionary. Most of the time it will be even faster to write a query that accesses some of its views than use IDE features.
You can get columns from view ALL_TAB_COLUMNS.
SELECT *
FROM ALL_TAB_COLUMNS
WHERE TABLE_NAME = :your_table_name
AND COLUMN_NAME LIKE '%YOUR_SEARCH_STRING%'
As for SQL Developer, you can open table from your connections tree, go to Columns tab and just use Edit -> Find (Ctrl/Cmd + F). Works for me in 4.0.2.15.
I would prefer writing a query is more faster compared to IDE provided buttons and clicks.
If so this would work out.
Use the following.
You can try this via SQL tool that is used by you
select table_name from all_tab_columns where column_name = 'PICK_COLUMN';
Or if you have DBA privileges,
select table_name from dba_tab_columns where column_name = 'PICK_COLUMN';
But if you are not sure about the column names you can add LIKE statements to current query.
Eg:
select table_name from all_tab_columns where column_name LIKE '%PICK_COLUMN%';
There is no search feature in the SQL Developer data grids for finding/navigating to a specific Column, but I'll add that as a feature request.
You may find the Single Record View handy for browsing very WIDE records.
On toolbar, Click View->Find DB Object
Now select the connection, the type and which column the value has to be found in. (NAME,TYPE AND USAGE(ALL))
The tables are displayed, select the table to view the columns having the field you are searching for.
Right click on column header in the data grid, then you have a menu Columns where you can filter columns you want to display
Right click on your connection name.
Then click "Find DB Object" on the context menu.
It will take you to a textbox. Write your column name
And check the box with "Columns".
Then press "enter" or click on "Go".
Then sqldeveloper will search your column and will show you the result [ column name with table name].

I'd like to know whether it is possible to do a insert into select statement with the use of right-click in SQL Server Manegement Studio (SSMS). And if not, is that tweakable?
When right-clicking on a table in the database (example here, I know I can right-click the target table, select 'Script Table as'/'Select to',paste the script,right-click the source-table, select 'Script Table as'/'Select to' and paste that in the just pasted piece of script instead of the VALUES-part. I want somehow to bypass these steps and possibly there is a simple way to do it already. But then I have to see 'Insert into select', or something. I'd like SSMS to generate for me a script something like this:
USE [DatabaseName]
GO
INSERT INTO [TableAA_New]
([A]
,[B]
,[C])
SELECT [A]
,[B]
,[C]
FROM [TableAA]
GO
So, my question is whether there is some right-click option that I don't see?
If there's not, is there some way of adding such a possibility to the right-click options? Can I tweak those? Actually a kind of extending the right-click menu in SSMS... Can anyone tell me or get me in the right direction?
Not 100% this is what you mean, But yes you can
if you have
SELECT * FROM MyTable
Select it then right click it. You get a context menu with an option "Design Query in Editor..."
This pops up a UI for building SQL. At the top of this window is a section where you can see the tables involved. If you right click on the white space in this top window you get another context menu with "Change type" this allows you to change your statement into an insert statement.
If you select insert values then you can input values that you want to insert into the table (on the UI)
But i expect you want "insert results". Selecting this means you then need to select the target table. You then need to map values from one table to another by updating the append column on the UI. If the target tables has the same columns as the source then the append column will be automatically updated to match the two columns.
Once done you get
INSERT INTO OtherTable
(A,B,C)
SELECT A,B,X
FROM MyTable
Hope this helps
Based on the answer #Paul-Spain gave, see beneath a way to make insert into select statement with (right-)mouse clicks. In effect you use Design Query in Editor.
Beneath is described how to use Design Query to insert into select from source table MyTable to target table OtherTable.
First a piece of script to get you started, e.g. to make MyTable and OtherTable, and to fill MyTable.
CREATE TABLE [dbo].[MyTable](
[A] [nvarchar](100) NULL,
[B] [nvarchar](100) NULL,
[C] [nvarchar](100) NULL
)
CREATE TABLE [dbo].[OtherTable](
[A] [nvarchar](100) NULL,
[B] [nvarchar](100) NULL,
[C] [nvarchar](100) NULL
)
insert into MyTable values (1,2,3),(4,5,6),(7,8,9);
1: Right-click somewhere in query window
2: A pop-up appears. Select the table you want as SELECT-table.
3: Right-click somewhere, select Change Type, Insert Results. So you actually give order to the dbms to insert the results of the curent query, that is based on MyTable. So you say to insert that somewhere. Where to insert it you define in a next window.
4: Select the table where to insert it too. If you don't have the table yet, you will have to make it. (That's also possible in this editor).
5: Tell the dbms which columns to select.
6: Run the generated script.
7: The data is inserted in OtherTable. Done.
how to get data from a specific column in fire bird? something like.
select from rdb$relation_fields
where rdb$relation_name = 'table' and rdb$field_name = 'code'
Your question doesn't quite make sense to me - if you already know the table and field name (as you do in your example) then why not select directly from the table? Anyway, you can create SQL statement dynamically in PSQL as string and then execute it using EXECUTE STATEMENT. The EXECUTE BLOCK might also be of intrest, depends where and what exactly youre tring to achieve.
EDIT after reading the comment
So just build the SELECT statement at the client side, selecting the field currently selected in combobox. You don't mention the language you use but generaaly it something like
query.SQL := 'SELECT '+ comboField.Text +' FROM '+curTableName;
query.Open();
// read the resultset
I installed the war file distribution using the install scripts in buildomatic. The installation is successful but when I boot tomcat server it shows some database exceptions
https://gist.github.com/shruti-palshikar/5ae801674dbd2a537518
I checked if the latest postgres driver exists in the tomcat/lib.
I also checked if the database 'jasperserver' has all the necessary tables
However these tables are empty , does anyone know which script loads data into tables?
Any help is appreciated
The actual error from PostgreSQL is:
relation "jiresourcefolder" does not exist
The query seems to be:
select this_.id as id5_0_, this_.version as version5_0_, this_.uri as uri5_0_, this_.hidden as hidden5_0_, this_.name as name5_0_, this_.label as label5_0_, this_.description as descript7_5_0_, this_.parent_folder as parent8_5_0_, this_.creation_date as creation9_5_0_, this_.update_date as update10_5_0_
from JIResourceFolder this_ where (this_.uri=?)
Typically ugly framework generated SQL.
There are only two possibilities:
There is no table "jiresourcefolder", "JIResourceFolder" or any other variation in capitals.
The table was created with quotes to preserve its case and the query is not using quotes.
The following will work:
CREATE TABLE JiReSoRrCeFoLdEr ...
SELECT * FROM jiresourcefolder...
SELECT * FROM JIRESOURCEFOLDER...
SELECT * FROM JIresourceFolder...
Any unquoted table (or column) names are internally mapped to lower-case so will all match.
If however you quote a created table:
CREATE TABLE "JIResourceFolder"
SELECT * FROM "JIResourceFolder" -- works
SELECT * FROM JIResourceFolder -- doesn't
Check your database schema and see if you have this table and whether it is all lower-case. Then, check the documentation for your java framework(s) and see if there is some flag that controls quoting of database tables. It seems likely that the flag is set in one place and not in another.
I just had the same issue in Jasper Studio.
My problem was that a wrong Data Adapter (a DB that did not have such a table) was assigned to the Report.
I had switch to the Design window and select the right Data Adapter in the upper right of that window right beside "Settings".
Windows/NET/ODBC
I would like to get query results to new table on some handy way which I can see through data adapter but I can't find a way to do it.
There is no much examples around to satisfy beginner's level on this.
Don't know temporary or not but after seeing results that table is no more needed so I can delete it 'by hand' or it can be deleted automatically.
This is what I try:
mCmd = New OdbcCommand("CREATE TEMP TABLE temp1 ON COMMIT DROP AS " & _
"SELECT dtbl_id, name, mystr, myint, myouble FROM " & myTable & " " & _
"WHERE myFlag='1' ORDER BY dtbl_id", mCon)
n = mCmd.ExecuteNonQuery
This run's without error and in 'n' I get correct number of matched rows!!
But with pgAdmin I don't see those table no where?? No matter if I look under opened transaction or after transaction is closed.
Second, should I define columns for temp1 table first or they can be made automatically based on query results (that would be nice!).
Please minimal example to illustrate me what to do based on upper code to get new table filled with query results.
A shorter way to do the same thing your current code does is with CREATE TEMPORARY TABLE AS SELECT ... . See the entry for CREATE TABLE AS in the manual.
Temporary tables are not visible outside the session ("connection") that created them, they're intended as a temporary location for data that the session will use in later queries. If you want a created table to be accessible from other sessions, don't use a TEMPORARY table.
Maybe you want UNLOGGED (9.2 or newer) for data that's generated and doesn't need to be durable, but must be visible to other sessions?
See related: Is there a way to access temporary tables of other sessions in PostgreSQL?
I was trying to do select for all entries in select statement - abap. I'm not getting the clear idea what select for entries does. Does any one know ?
Kindly have a look at the statements below:
1.
select bukrs belnr xblnr budat
from bkpf
into table it_bkpf
where belnr in s_belnr
2.
select bukrs belnr buzei gsber zuonr wrbtr kunnr
from bseg
into table it_bseg
for all entries in it_bkpf
where belnr = it_bkpf-belnr.
Please let me know the difference in two statements.
Siva
Some obvious differences:
Different tables
Different target fields
The 2nd select had a syntax problem: You used form instead from (I corrected it with my edit)
Other differences:
The selection 1.) uses in in the where clause. So it uses a select-options (or a range-object).
for all entries in it_bkpf means, that the internal table it_bkpf contains a list of elements, you want to select. Or in other words: Select all entries in bseg, where a filed belnr is an element of hte internal table bseg.
You will get clear answer through ST05 transaction.
You could execute st05 transaction, choose trace SQL and activate
trace.
After that run your code.
Enter st05 again choose deactivate trace, then view trace result.
There you can see exact SQL code that is forwarded to database server. As BSEG is clustered table, you could not use intuitive header-item join to retrieve needed financial movements inforamation. It's just because there are several tables including BSEG are storing in single database table, so database server technically can not separate BSEG rows and find BSEG-specific fields to make proper join.
So you can do join-like construction at application server. First you are retrieving all header-related columns from header table ( BKPF). Next when SELECT ... FOR ALL ENTRIES IN ... is executed application server will take a little portions of header rows (typically 5) and construct SQL queries for retrieving packs of items, corresponding to that portions. Next all that portions will merged in single internal table. So there will be only items of desired document as it were if you could execute normal join.
Here's what happens the way I understand it. The two statements are probably executed after another:
The first statement selects a few entries from the bkpf table. These entries are stored in the internal table it_bkpf (say belnr 1, 2, 3).
Each of these entries is then used as part of the select #2. The "for all entries" matches the belnr in table bseg to those in the internal table it_bkpf from the first statement. The matching entries are then put into the internal table it_bseg.
With the example you've given this is pretty much the same if the where clause in SQL #2 was where belnr in s_belnr (instead of the whole for all entries). This would only make sense if you needed the contents of it_bkpf for some other purpose. Another typical situation is if you determine the contents of the internal table used in the for all entries clause with some program logic instead of reading it directly from the database.
One catch with "for all entries": Make sure the internal table in the for all entries is not empty - then the whole table in the from clause would be selected.
