https://dbgate.io/dbgate-classic/sql-and-queries/index.html Query your data in whatever way suits you. Write SQL directly in a full-featured editor with formatting, code completion and editable results, or build queries visually with the query designer - no SQL knowledge required. ER diagrams round this out by showing how your tables relate, so you can understand the database before you query it. SQL editor - execute scripts, format and complete SQL, edit query results Query designer - build SQL visually, without writing code ER diagrams - visualize table relations and database structure Hugo en-us https://dbgate.io/dbgate-classic/sql-and-queries/sql-editor/index.html Mon, 01 Jan 0001 00:00:00 +0000 https://dbgate.io/dbgate-classic/sql-and-queries/sql-editor/index.html The SQL editor is where you write and run SQL scripts against your connection. Open it from the “New query” button in the toolbar, or from the context menu of a connection or database. Running SQL Execute script - run the whole script with the Execute button (or F5). Execute current statement - run only the statement under the cursor. Run selection - if you select part of the script, only the selected text is executed. Results appear in the result grid below the editor. Multiple result sets are shown in separate tabs. Messages, row counts and errors are shown in the Messages tab. Editing helpers SQL code formatter - reformat the current script for consistent indentation and casing. Code completion - table, column and keyword suggestions based on the connected database schema. Join helper - the “Add SQL join” utility generates a LEFT/INNER/RIGHT JOIN clause from foreign keys, so you don’t have to type join conditions by hand. Working with results The result grid uses the same engine as the data browser, so you can filter and sort, copy cells in various formats and export the result. https://dbgate.io/dbgate-classic/sql-and-queries/query-designer/index.html Mon, 01 Jan 0001 00:00:00 +0000 https://dbgate.io/dbgate-classic/sql-and-queries/query-designer/index.html The query designer (Premium) lets you build SQL queries visually, without writing SQL by hand. Add tables to the canvas, pick columns and define conditions - DbGate generates the SQL for you. Building a query Add tables - drop tables onto the design canvas; DbGate draws relations from foreign keys automatically. Pick columns - choose which columns appear in the result, define sorting and grouping. JOIN types - besides the standard SQL joins (INNER, LEFT, RIGHT), you can use pseudo-joins - the most useful being WHERE NOT EXISTS. Powerful filters - filter using the same engine as the data browser, including compound conditions and filtering by a set of values. Result The designer produces a normal SQL query, so it runs with the same performance as hand-written SQL. You can switch to the generated SQL at any time and continue editing it in the SQL editor. https://dbgate.io/dbgate-classic/sql-and-queries/er-diagrams/index.html Mon, 01 Jan 0001 00:00:00 +0000 https://dbgate.io/dbgate-classic/sql-and-queries/er-diagrams/index.html ER (entity-relationship) diagrams visualize your tables and the relations between them. Generate a diagram for the whole database or for a selected set of tables. Creating a diagram Show relations for a single table, or the structure of the full database. Add tables to an existing diagram from the database object tree. Customizing the diagram (advanced settings are Premium) Colors and groups - change the color of a table and define logical groups of tables. Choose columns - show all columns, only not-null columns, or only primary-key columns. Attributes - configure whether data types and NULL/NOT NULL flags are shown. Export Export the diagram to a simple, self-contained HTML page to share it or include it in documentation.
