Write SQL statements in Navicat

Navicat is a database management tool that allows users to write and execute SQL statements to manage databases. Here are the steps to write SQL statements:

1. Connect to the database

First, use Navicat to connect to the target database. In the left pane of the Navicat home page, right-click the Database node and select Connect to Database. Enter the database connection information and click Connect.

2. Create a new query window

Once connected to the database, click the New Query button on the home page toolbar. This will create a new query window.

3. Write SQL statements

In the query window, enter the required SQL statement. SQL statements usually start with keywords, such as SELECT, INSERT, UPDATE, or DELETE.

4. Execute query

After writing the SQL statement, click the Run button on the query window toolbar to execute it. The query results will be displayed at the bottom of the window.

5. Save the query

For later use, the query can be saved as a file. In the File menu in the query window, select Save or Save As.

SQL statement example

Here are some common SQL statement examples:

• SELECT * FROM table_name; : Select all rows and columns in the table.
• INSERT INTO table_name (column1, column2) VALUES (value1, value2); : Insert a row in the table.
• UPDATE table_name SET column1 = value1 WHERE column2 = value2; : Update rows in the table.
• DELETE FROM table_name WHERE column1 = value1; : Delete rows from the table.

Things to note

• SQL statements are case-insensitive, but for readability, it is recommended to use uppercase keywords.
• When entering text values, use single quotes.
• When entering a date or time value, use single quotes or a specific date/time format.
• Use brackets and semicolons correctly to ensure the correctness of SQL statements.
