Query params regex can now be changed between four variables: To use double quotes, simply use the Shift key and the double quote (“) key. Users also have the ability to wrap selected in quotes by highlighting strings in the editor and then pressing the quote (‘) key, which will wrap the highlighted area with the single quote.

You can read our review of TablePlus for MacOS here.Īmongst numerous bug fixes and performance improvements, the changes include multiple cursors (carets) to enable multiple selection in TablePlus Query Editor. The most recent version, designed for macOS 10.11 and newer, brings a number of new changes. It supports databases including: PostgreSQL, MySQL MariaDB SQLite Microsoft SQL Server Amazon Redshift Oracle CockroachDB Snowflake Cassandra Redis Vertica MongoDB (Beta) and any databases that use the same protocol with the databases listed above such as Percona, and Yugabyte DB. Users will also have the ability to edit inline, preview SQL, view data structure run custom queries and use advanced filters.Ĭurrently TablePlus provides apps across macOS, iOS and Windows. The beta app will include MySQL and PostgreSQL support, as well as an SSH tunnel with password/private key. Import .TablePlus, a creator of GUI tools for relational databases, has provided a sneak peek of its new Linux app, due for release at the end of November. Given below is the complete program to read data from a table. The select queries will return the result in the form of a ResultSet object, therefore store the result in the object of RESULTSET class as shown below. Store the query in a string and pass it to the execute() method of session class as shown below.Įxecute the query using the execute() method of Session class. In this example, we are retrieving the data from emp table. Whatever you pass to this method in string format will be executed on the cqlsh. Pass the query either in string format or as a Statement class object to the execute() method. You can execute CQL queries using execute() method of Session class. Therefore, create the session object as shown below. Here we are using the KeySpace called tp. Session session = nnect(“Your keyspace name”) If you already have a keyspace, then you can set it to the existing one by passing the KeySpace name in string format to this method as shown below. This method creates a new session and initializes it.

You can build the cluster object using a single line of code as shown below.Ĭluster cluster = Cluster.builder().addContactPoint('127.0.0.1').build() Ĭreate an instance of Session object using the connect() method of Cluster class as shown below. Use the following code to create the cluster object. To do so, you have a method called build() in the Cluster.Builder class. Using the new builder object, create a cluster object. Adding contact point to the Cluster.Builder objectĬluster.Builder builder2 = build.addContactPoint( '127.0.0.1' ) Step1:Create a Cluster ObjectĬreate an instance of Cluster.builder class of package as shown below.Ĭluster.Builder builder1 = Cluster.builder() Īdd a contact point (IP address of the node) using the addContactPoint() method of Cluster.Builder object. Follow the steps given below to execute multiple statements using batch statement with the help of Java API. You can read data from a table using the execute() method of Session class. First of all, set secondary index to the column emp_sal.Ĭqlsh:tutorialspoint> CREATE INDEX ON emp(emp_sal) Ĭqlsh:tutorialspoint> SELECT * FROM emp WHERE emp_sal=50000 In the following example, we are reading the details of an employee whose salary is 50000. Note − A WHERE clause can be used only on the columns that are a part of primary key or have a secondary index on them. Using WHERE clause, you can put a constraint on the required columns.

The following example shows how to read a particular column in a table.Ĭqlsh:tutorialspoint> SELECT emp_name, emp_sal from emp Here we are reading a table called emp.Įmp_id | emp_city | emp_name | emp_phone | emp_sal The following example shows how to read a whole table using SELECT clause.

Given below is the syntax of SELECT clause.Īssume there is a table in the keyspace named emp with the following details − emp_id Using this clause, you can read a whole table, a single column, or a particular cell. SELECT clause is used to read data from a table in Cassandra.
