When I create table by "creata table I have method to check if table with that name exist - and it works good. So when I create table I try to do commit, too - do not helptable appear in SQL developer but when i check by my method if that table exist i get 'false' do not existwhen I restart database and run what to serve at morning tea, my method return 'true'.

I think is a problem with session but I don't now how to get over with that. But then when you're fetching the data from rsyou're making a case-sensitive comparison with rs. At a minimum, that ought to be equalsIgnoreCase.

But there should be no need to do the xreate at all in Java since your SQL statement is already doing it. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Your procedure can't see the table because it doesn't have the rights to see it. Can we see the code that creates the table and the code that checks whether it exists?

Matthew Farwell: I don't think so. When he restarts the database, the procedure sees the table I don't think so, that this is problem with rights because my procedure see that tables that new created if I restart database created earlier see without restart — user Jaba 28 '12 at I believe that's what you're saying that you're seeing.

I don't carry on SQL injection because this is for my own use: upper-case I use because oracle use upper case in table name always in sql statment is irrelevant — user Feb 28 '12 at Ofacle in the code where you are fetching from the result set, you are doing a case-sensitive comparison.

If the table name passed in to the function is not upper case, the equals comparison will fail despite the fact that the query determined that the table does in fact exist. I have checked how to make carnations change color You have right.

Oracle CREATE TABLE Example

Here is typical code for creating a scroll pane that serves as a container for a table: JScrollPane scrollPane = new JScrollPane(table); likedatingen.comlsViewportHeight(true); The two lines in . Oracle CREATE TABLE. In Oracle, CREATE TABLE statement is used to create a new table in the database. To create a table, you have to name that table and define its columns and datatype for each column. Syntax: CREATE TABLE table_name. . column1 datatype [ NULL | NOT NULL ], column2 datatype [ NULL | NOT NULL ]. enter code here public void prepStatExecuteCreateTable(String name){ String createTable= "Create table "+ name +" (ID NUMBER(*, 0) NOT NULL PRIMARY KEY, CZAS NUMBER(*, 0) NOT NULL, OTWARCIE NUMBER(6, 2) NOT NULL, MAX_KURS NUMBER(6, 2) NOT NULL, MIN_KURS NUMBER(6, 2) NOT NULL, ZAMKNIECIE NUMBER(6, 2) NOT NULL, VOLUMEN NUMBER(*, 0) .

Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available. With the JTable class you can display tables of data, optionally allowing the user to edit the data. JTable does not contain or cache data; it is simply a view of your data. Here is a picture of a typical table displayed within a scroll pane:. The rest of this section shows you how to accomplish some common table-related tasks. Here are the topics this section covers:.

Or, to compile and run the example yourself, consult the example index. Click the cell that contains "Snowboarding". The entire first row is selected, indicating that you have selected Kathy Smith's data. A special highlight indicates that the "Snowboarding" cell is editable. Generally, you begin editing a text cell by double-clicking it. Position the cursor over "First Name". Now press the mouse button and drag to the right.

As you can see, users can rearrange columns in tables. Position the cursor just to the right of a column header. Now press the mouse button and drag to the right or left. The column changes size, and the other columns adjust to fill the remaining space. The table in SimpleTableDemo. The advantage of these constructors is that they are easy to use. However, these constructors also have disadvantages:. If you want to get around these restrictions, you need to implement your own table model, as described in Creating a Table Model.

Here is typical code for creating a scroll pane that serves as a container for a table:. The scroll pane automatically places the table header at the top of the viewport. The column names remain visible at the top of the viewing area when the table data is scrolled. If you are using a table without a scroll pane, then you must get the table header component and place it yourself. For example:. By default, all columns in a table start out with equal width, and the columns automatically fill the entire width of the table.

When the table becomes wider or narrower which might happen when the user resizes the window containing the table , all the column widths change appropriately.

When the user resizes a column by dragging its right border, then either other columns must change size, or the table's size must change. By default, the table's size remains the same, and all columns to the right of the drag point resize to accommodate space added to or removed from the column to the left of the drag point. To customize initial column widths, you can invoke setPreferredWidth on each of your table's columns.

This sets both the preferred widths of the columns and their approximate relative widths. For example, adding the following code to SimpleTableDemo makes its third column bigger than the other columns:. As the preceding code shows, each column in a table is represented by a TableColumn object.

TableColumn supplies getter and setter methods for the minimum, preferred, and maximum widths of a column, as well as a method for getting the current width. For an example of setting cell widths based on an approximation of the space needed to draw the cells' contents, see the initColumnSizes method in TableRenderDemo. When the user explicitly resizes columns, the columns' preferred widths are set such that the user-specified sizes become the columns' new current widths.

Instead, the existing preferred widths are used to calculate new column widths to fill the available space. You can change a table's resize behavior by invoking setAutoResizeMode. In its default configuration, a table supports a selection that consists of one or more rows.

The user can select a contiguous range of rows or an arbitrary set of rows. The last cell that the user indicated gets a special indication; in the Metal look and feel, the cell is outlined.

This cell is known as the lead selection ; it is sometimes called "the cell with the focus" or "the current cell". This example program presents the familiar table, and allows the user to manipulate certain JTable options. There is also a text pane that logs selection events. In the screenshot below, a user has run the program, clicked in the first row, then control-clicked in the third row.

Notice the outline around the last cell clicked; this is how the Metal look and feel highlights the lead selection. Under "Selection Mode" there are a set of radio buttons.

Click the one labelled "Single Selection". Now you can only select one row at a time. If you click on the "Single Interval Selection" radio button, you can select a set of rows that must be contiguous.

All of the radio buttons under "Selection Mode" invoke JTable. This method takes a single argument, which must be one of the following constants defined in javax. If you clear all three check boxes setting all three bound properties to false , there is no selection; only the lead selection is shown. You may notice that the "Cell Selection" checkbox is disabled in multiple interval selection mode. This is because cell selection is not supported in this mode in the demo. You can specify selection by cell in multiple interval selection mode, but the result is a table that does not produce useful selections.

You may also notice that changing any of the three selection options can affect the others. This is because allowing both row selection and column selection is exactly the same as enabling cell selection.

JTable automatically updates the three bound variables as necessary to keep them consistent. To retrieve the current selection, use JTable. To retrieve the coordinates of the lead selection, refer to the selection models for the table itself and for the table's column model. The following code formats a string containing the row and column of the lead selection:.

User selections generate a number of events. Every table object uses a table model object to manage the actual table data. A table model object must implement the TableModel interface. If the programmer does not provide a table model object, JTable automatically creates an instance of DefaultTableModel. This relationship is illustrated below. As the preceding code shows, implementing a table model can be simple.

Generally, you implement your table model in a subclass of the AbstractTableModel class. Your model might hold its data in an array, vector, or hash map, or it might get the data from an outside source such as a database. It might even generate the data at execution time. See below the code taken from TableDemo. Bold font indicates the code that makes this table's model different from the table model defined automatically for SimpleTableDemo.

A table model can have a set of listeners that are notified whenever the table data changes. Listeners are instances of TableModelListener. In the following example code, SimpleTableDemo is extended to include such a listener.

New code is in bold. In order to fire data change events the table model must know how to construct a TableModelEvent object. This can be a complex procedure, but is already implemented in DefaultTableModel. If DefaultTableModel is not a suitable base class for your custom table model class, consider subclassing AbstractTableModel.

This class implements a simple framework for constructing TableModelEvent objects. Your custom class simply needs to invoke one the following AbstractTableModel methods each time table data is changed by an external source. Before you go on to the next few tasks, you need to understand how tables draw their cells. You might expect each cell in a table to be a component.

However, for performance reasons, Swing tables are implemented differently. Instead, a single cell renderer is generally used to draw all of the cells that contain the same type of data. You can think of the renderer as a configurable ink stamp that the table uses to stamp appropriately formatted data onto each cell. When the user starts to edit a cell's data, a cell editor takes over the cell, controlling the cell's editing behavior.

By default, the cell renderer for a Number -containing column uses a single JLabel instance to draw the appropriate numbers, right-aligned, on the column's cells. If the user begins editing one of the cells, the default cell editor uses a right-aligned JTextField to control the cell editing. To choose the renderer that displays the cells in a column, a table first determines whether you specified a renderer for that particular column. If you did not, then the table invokes the table model's getColumnClass method, which gets the data type of the column's cells.

Next, the table compares the column's data type with a list of data types for which cell renderers are registered. This list is initialized by the table, but you can add to it or change it. Currently, tables put the following types of data in the list:. Remember that if you let a table create its own model, it uses Object as the type of every column. To specify more precise column types, the table model must define the getColumnClass method appropriately, as demonstrated by TableDemo. Keep in mind that although renderers determine how each cell or column header looks and can specify its tool tip text, a renderer does not handle events.
