TinyDB - Handling Data Query - We have already discussed how you can use the 'insert' query to store data in a database. On a similar note, you can use the 'insert_multiple' query to store multiple data items simultaneously. Here is the syntax of 'insert_multiple' query in TinyDB:
TinyDB - Logical OR - The Logical OR operator combines multiple conditions and evaluates to True only if either of the condition is met. TinyDB Logical OR operates on two queries of a database. If any one of the queries is True, TinyDB will fetch the required data. On the other hand, if both the queries are False, it w
TinyDB - Logical AND - The Logical AND operator combines multiple conditions and evaluates to True if all the conditions are met. TinyDB Logical AND operates on two queries of a database. If both the queries are True, TinyDB will fetch the required data. On the other hand, if any one of the queries is False, it will ret
TinyDB - The one_of() Query - For matching the subfield data, TinyDB provides a method called one_of(). This method searches a single category and gets at least one similar value. It will match if the field is contained in the provided list.
TinyDB - The test() Query - The test() query will test if the given arguments match with the data in a table. If it matches with the data, it will return the matched data, otherwise it will return blank. First of all, we need to define a test function and its arguments and then it will search the item in a given database.
TinyDB - The matches() Query - The matches() query matches the data from a JSON file with a given condition (in the form of a regular expression) and returns the results accordingly. It will return a blank value if the condition does not match with the data in the file.
TinyDB - The exists() Query - TinyDB provides an advanced query called exists() that checks the existence of data in a JSON file. The exists() query actually tests the availability of a subfield data from a JSON file. The exists() query works on the basis of a Boolean condition. If the subfield exists (i.e., BOOLEAN TRUE), it wi
TinyDB - The where Clause - TinyDB provides the where clause that you can use while searching for a particular data. The where clause helps by filtering the unwanted data out. With the help of the where clause, you can access specific data quickly.
TinyDB - Searching - TinyDB provides the search() method to help you search any data from a document. Along with the query() object, the search() method can be used to find the data in a JSON file. We have various ways in which we can use the search() method on a TinyDB database.
TinyDB - Delete Data - In case you need to delete a particular set of data permanently from a TinyDB database, you can do so by using the remove() method. Like for reteriving and updating the data, you first need to create an instance of the Query class for deleting the data. You can use the following command for this pur
TinyDB - Update Data - TinyDB can store data in many formats and we can easily reterive the stored data using various methods. But sometimes, we need to update the data, for which we can use the update() method.
TinyDB - Retrieve Data - There are numerous ways with the help of which you can retrieve data from a TinyDB database. But to use those ways, you first need to create an instance of the Query class as follows ?
TinyDB - Insert Data - We have created the instance of the TinyDB and passed a JSON file to it where our data will be stored. It is now time to insert the items in our database. The data should be in the form of a Python dictionary.
