The below example shows that create a table by using jsonb data type. Examplesīelow is the example of jsonb data type in PostgreSQL. We have also used the aggregate function such as min, max, average, and sum with jsonb data type. We can also use the jsonb data type column in the where clause for retrieving data from the column.ġ0. The second operator is used to return the text from the json object field.ĩ. This operator is very important while querying data.Ĩ. The first operator is used to return the key to the json object field in PostgreSQL. Below is the operator available in PostgreSQL to query the jsonb data in PostgreSQL.ħ. Also, we have used two operators to query the jsonb type of data in PostgreSQL. To select the jsonb data type column data in PostgreSQL we have used a select statement same as we have used other data types of column.Ħ. We can insert single as well as multiple values at the same time into the jsonb data type column in PostgreSQL.ĥ. To insert data into the jsonb data type column we need to ensure that the data will contain the proper JSON format.Ĥ. Before the version of 9.4 jsonb data type is not available.ģ. Jsonb data type in PostgreSQL introduced from the version of 9.4. In PostgreSQL, the json data type is stored actual copy of the data which was we have inserted into the table whereas jsonb data type stores the binary form of data in binary code.Ģ. Using GIN – This is defined as creating an index on the jsonb data type column by using the GIN index type.ġ.The name of the index is a very useful and important parameter while creating an index in PostgreSQL. Name of the index – It is defined as the name of the index which was we have to create on the jsonb data type column in PostgreSQL.We have to create the GIN index on the jsonb data type column for faster-accessing data. Create index – This is defined as to create the index in PostgreSQL on jsonb data type column.We are using any data type to the column at the time of table creation in PostgreSQL. Data type – This is defined as the data type which was we have used on the column at the time of table creation.We can define any data type to the column at the time of table creation. ![]() Name of the column – This is defined as a table column from which we have defined the data type as jsonb.Using jsonb data type we are restoring the jsonb data into the table. Name of the table – This is defined as the name of the table on which table column we have defined the data type as jsonb.We have created a table and defined the data type of jsonb to its column. Create table – This is defined as to create a table by using the jsonb data type column. ![]() Create an index on jsonb data type column Create index name_of_index on name_of_table using GIN (name_of_column) īelow is the parameter description syntax of jsonb data type in PostgreSQL. Create a table using jsonb data type Create table name_of_table (name_of_column1 data_type, name_of_column2 data_type,name_of_column1 jsonb, …, name_of_columnN data_type) 2.
