How to use Navicat to query specific data in the table

Navicat is a powerful database management tool. It helps you manage and query your database easily. To query specific data in a table, you can use the following statement: 

<code class="sql">SELECT <列名> FROM <表名> WHERE <条件></code>

Where:

  • : The column you want to query name.
: The name of the table you want to query.
  • : Specify the conditions for the data to be queried.

    • For example, to query the names and emails of all customers named "John" in the customers table, you would use the following statement: 

    <code class="sql">SELECT name, email FROM customers WHERE name = 'John'</code>

    Steps:

    1. Open Navicat and connect to your database.
    2. Right-click the table you want to query and select "SQL Editor".
    3. Insert the query statement in the SQL editor.
    4. Click the Run button or press the F5 key to execute the query.
    5. The query results will be displayed below the SQL editor.

    Additional options:

    • Fuzzy query: Use the wildcard character % for fuzzy query. For example, query for all customers named "Jo%": 
    <code class="sql">SELECT name, email FROM customers WHERE name LIKE 'Jo%'</code>
    • Sort: Use the ORDER BY clause to sort the query results . For example, to sort by customer name in ascending order: 
    <code class="sql">SELECT name, email FROM customers ORDER BY name ASC</code>
    • Limit the results: Use the LIMIT clause to limit the number of records returned. For example, return the first 10 records: 
    <code class="sql">SELECT name, email FROM customers LIMIT 10</code>
