Indicates that the data is not sorted in this column. If you prefer to use the stacked sorting, click a column name while pressing Alt. It means that if you click a column name to sort data by, the sorting based on other columns will be cleared. The column sorting is not stacked by default. If one and the same tab is used to show your query results, and you get the result that you want to keep, you can pin the tab to the tool window.Ĭlick the column name to sort the column data. See another example of comparing two result sets in Compare data at. For example, if you want to consider two rows as equal if their data differs in a single column, enter 1 in the Tolerance field. The Tolerance parameter defines a maximum number of differences that are allowed between two result sets. If needed, change a value of the Tolerance parameter in the comparison dialog. In the Services tool window, click the Compare with icon ( ), and select the result set that you want to add to diff. Run queries to tables that you want to compare. On the toolbar, click the Export Data icon ( ) and select Copy To Clipboard. Select data in the result set or in the editor and press Ctrl+C. In the Export Data dialog, click Export to File. On the toolbar, click the Export Data icon ( ) and select Export to File. Right-click a query and select Export Data to &File. Right-click a result set, a table, or a view, select Export Data. To export data to a file, perform one of the following actions: Like in the data editor, you can edit values in the result set, auto-commit changes, delete rows, search text, and navigate through data. To submit changes to a database, click the Submit icon ( ), or press Ctrl+Enter. In the result set, click a cell value that you want to edit. To disable this feature, open settings Ctrl+Alt+S, navigate to Tools | Database | Query Execution | Output and Results, and clear the Create title for results from comment before query checkbox.įor more examples of custom titles for tabs, see Name the result tabs at. In the Treat text as title after field, define a combination for tab titles. Open settings by pressing Ctrl+Alt+S, navigate to Tools | Database | Query Execution | Output and Results. By default, no combination is used, so any text after - or /* is treated as a tab title. In the Treat text as title after field, you can reserve a combination of symbols or characters after which any text will be treated as a tab title. You can define a tab title in the comment section before the query. Select the Open results in new tab checkbox and click OK.Ĭlick the In-Editor Results button to view result sets one above another. In the IDE settings Ctrl+Alt+S, go to Tools | Database | Query Execution. You can change this behavior and create a tab each time you run a query. Open a new tab for each queryīy default, IntelliJ IDEA updates the same tab with results each time you run a query. The Services tool window includes a list of consoles that are grouped according to a connection session to a data source. For example, if you have two SELECT statements in the query, you will see two tabs in the tool window. Each statement appears in a separate tab in the Services tool window. By looking at the index, you can quickly identify page numbers based on the keywords.Usually, when you run a query, you receive results in a table format. Imagine an index in the database like an index of a book. This helps SQLite quickly locate the row based on the values of the indexed columns. The index contains data from the columns that you specify in the index and the corresponding rowid value. Whenever you create an index, SQLite creates a B-tree structure to hold the index data. An index consists of one or more columns, but all columns of an index must be in the same table. How does an index workĮach index must be associated with a specific table. In addition, querying using equality (=) and ranges (>, >=, <,<=) on the B-tree indexes are very efficient. The B-tree keeps the amount of data at both sides of the tree balanced so that the number of levels that must be traversed to locate a row is always in the same approximate number. Note that B stands for balanced, B-tree is a balanced tree, not a binary tree. SQLite uses B-tree for organizing indexes. An index is an additional data structure that helps improve the performance of a query. Unlike a table, an index has an opposite relationship: (row, rowid). Therefore, you can consider a table as a list of pairs: (rowid, row). Each row also has a consecutive rowid sequence number used to identify the row. In the same time, each row has the same column structure that consists of cells. In relational databases, a table is a list of rows. #Db browser for sqlite sort multiple columns how to#Summary: in this tutorial, you will learn how to use SQLite indexes to query data faster, speed up sort operation, and enforce unique constraints.
