Microsoft SQL Server Database Quiz Questions

SQL Server does not have a specific JSON data type; instead, JSON data is stored in columns of type `NVARCHAR`.

SQL Server provides functions like `JSON_VALUE` and `OPENJSON` to query JSON data stored in `NVARCHAR` columns.

The `JSON_QUERY` function returns an object or an array from a JSON string, not a single scalar value. `JSON_VALUE` is used for scalar values.

SQL Server cannot index JSON data directly; indexes must be created on the columns that contain JSON data, but not on the JSON data itself.

`OPENJSON` parses JSON data and returns it in a tabular format, making it easier to work with JSON data in SQL Server.

The `JSON_MODIFY` function allows you to update values in a JSON string stored in a column.

JSON support was introduced in SQL Server 2016. Earlier versions do not have native support for JSON functions.

The `JSON_VALUE` function extracts scalar values from JSON strings. For arrays, you should use `JSON_QUERY`.

JSON functions in SQL Server work with `NVARCHAR` columns, not `VARCHAR`.

The `JSON_QUERY` function extracts objects or arrays from a JSON string, not single scalar values.

JSON functions require `NVARCHAR` columns, and `TEXT` is deprecated. Use `NVARCHAR(MAX)` for large JSON data.

`JSON_VALUE` is used to extract values from JSON strings, not to update them. Use `JSON_MODIFY` for updates.

SQL Server does not provide native support for JSON schema validation; it focuses on JSON data manipulation.

`OPENJSON` can be used to return nested JSON objects as separate rows, making it easier to work with complex JSON data.

JSON data can be queried and used alongside traditional relational data in SQL Server, allowing for flexible data models.

The `JSON_VALUE` function extracts scalar values from JSON strings.

The `JSON_QUERY` function is used to extract arrays or objects from JSON strings.

`OPENJSON` parses JSON strings and returns the results in a tabular format.

JSON data should be stored in columns of type `NVARCHAR`.

`JSON_MODIFY` is used to update values in a JSON string.

SQL Server does not have a `JSON_PARSE` function. The available functions include `JSON_VALUE`, `JSON_QUERY`, `OPENJSON`, and `JSON_MODIFY`.

JSON data should be stored in `NVARCHAR` columns. `TEXT` is deprecated and `VARCHAR` lacks Unicode support.

`OPENJSON` function returns JSON objects or arrays as rows in a result set.

`JSON_VALUE` is used to extract specific scalar values from JSON objects.

Functions like `JSON_VALUE`, `JSON_QUERY`, `OPENJSON`, and `JSON_MODIFY` are used for JSON data manipulation. `JSON_APPEND` does not exist.

`OPENJSON` returns a tabular result set that includes rows and columns.

`JSON_QUERY` extracts JSON objects or arrays from a JSON string.

`JSON_MODIFY` is used to update a JSON object or array within a JSON string.

`JSON_MODIFY` updates the value of a property in a JSON string.

`OPENJSON` is used to parse JSON data into rows and columns.

SQL Server provides multiple functions to extract data from JSON strings.

SQL Server provides functions specifically for modifying JSON data.

To query JSON arrays, SQL Server provides specific functions.

SQL Server includes several functions for parsing and handling JSON data.

JSON data should be stored in specific data types to ensure proper handling.

Functions to work with JSON objects include those that handle extraction and modification.

Functions that handle JSON arrays are used to extract data.

Efficient handling of large JSON data is managed by specific functions.

ISJSON tests whether a string contains valid JSON and returns 1 when it is valid.

Functions that extract arrays or nested objects include those that handle complex data structures.

Functions for updating or manipulating JSON properties include those designed for modification.

Certain functions handle both JSON arrays and objects effectively.

Extraction from deeply nested structures can be handled by specific functions.

Modifying JSON arrays requires specific functions for updating data.

Querying JSON data involves functions that can extract or manipulate data.
