-#### Syntax
+## Description
+JSON_EXTRACT is a series of functions that extract the field specified by
json_path from JSON data and provide different series of functions according to
the type of the field to be extracted.
+
+* JSON_EXTRACT returns the VARCHAR type for a json string of the VARCHAR type.
+* JSON_EXTRACT_ISNULL returns the BOOLEAN type indicating whether it is a json
null.
+* JSON_EXTRACT_BOOL returns the BOOLEAN type.
+* JSON_EXTRACT_INT returns the INT type.
+* JSON_EXTRACT_BIGINT returns the BIGINT type.
+* JSON_EXTRACT_LARGEINT returns the LARGEINT type.
+* JSON_EXTRACT_DOUBLE returns the DOUBLE type.
+* JSON_EXTRACT_STRING returns the STRING type.
+
+## Alias
+* JSONB_EXTRACT is the same as JSON_EXTRACT.
+* JSONB_EXTRACT_ISNULL is the same as JSON_EXTRACT_ISNULL.
+* JSONB_EXTRACT_BOOL is the same as JSON_EXTRACT_BOOL.
+* JSONB_EXTRACT_INT is the same as JSON_EXTRACT_INT.
+* JSONB_EXTRACT_BIGINT is the same as JSON_EXTRACT_BIGINT.
+* JSONB_EXTRACT_LARGEINT is the same as JSON_EXTRACT_LARGEINT.
+* JSONB_EXTRACT_DOUBLE is the same as JSON_EXTRACT_DOUBLE.

series of functions are provided for different datatype.

-- jsonb_extract extract and return JSON datatype
-- json_extract_isnull check if the field is json null and return BOOLEAN

+## Parameters

+|--------------|-----------------------------|
+| `<json_str>` | The JSON-type parameter or field to be extracted. |
+| `<path>` | The JSON path to extract the target element from the target
JSON. |

+## Return Values
+According to the type of the field to be extracted, return the data type of
the specified JSON_PATH in the target JSON. Special case handling is as follows:
+* If the field specified by json_path does not exist in the JSON, return NULL.
+* If the actual type of the field specified by json_path in the JSON is
inconsistent with the type specified by json_extract_t.
+* if it can be losslessly converted to the specified type, return the
specified type t; if not, return NULL.

-- if datatype of the field specified by json_path is not the same with type of
json_extract_t, return t if it can be cast to t else NULL

-## json_parse
-### description
-#### Syntax
+
+## Description
+Parse the original JSON string into JSON binary format. To meet the needs of
different abnormal data processing, different JSON_PARSE series functions are
provided as follows:
+* JSON_PARSE: Parse the JSON string, and report an error when the input string
is not a valid JSON string.
+* JSON_PARSE_ERROR_TO_INVALID: Parse the JSON string, and return NULL when the
input string is not a valid JSON string.
+* JSON_PARSE_ERROR_TO_NULL: Parse the JSON string, and return NULL when the
input string is not a valid JSON string.
+* JSON_PARSE_ERROR_TO_VALUE: Parse the JSON string, and return the default
value specified by the parameter default_json_str when the input string is not
a valid JSON string.
+* JSON_PARSE_NOTNULL: Parse the JSON string, and return NULL when the input
string is not a valid JSON string.
+
+## Alias
+* JSONB_PARSE is the same as JSON_PARSE
+* JSONB_PARSE_ERROR_TO_INVALID is the same as JSON_PARSE_ERROR_TO_INVALID
+* JSONB_PARSE_ERROR_TO_NULL is the same as JSON_PARSE_ERROR_TO_NULL
+* JSONB_PARSE_ERROR_TO_VALUE is the same as JSON_PARSE_ERROR_TO_VALUE
+* JSONB_PARSE_NOTNULL is the same as JSON_PARSE_NOTNULL
+
+## Syntax
```sql
-JSON json_parse(VARCHAR json_str)
-JSON json_parse_error_to_null(VARCHAR json_str)
-JSON json_parse_error_to_value(VARCHAR json_str, VARCHAR default_json_str)
+JSON_PARSE (<json_str>)
+```
+```sql
+JSON_PARSE_ERROR_TO_INVALID (<json_str>)
+```
+```sql

```
+```sql
+JSON_PARSE_ERROR_TO_VALUE (<json_str>, <default_json_str>)
+```
+```sql
+JSONB_PARSE_NOTNULL (<json_str>)
+```
+
+## Parameters
+| Parameter | Description |
+|--------------|-----------------------------|
+| `<json_str>` | The JSON type parameter or field to be extracted. |
+| `<default_json_str>` | When the input string is not a valid JSON string,
return the default value specified by the parameter default_json_str. |
|
+
+## Return Values
json_parse functions parse JSON string to binary format. A series of functions
are provided to satisfy different demand for exception handling.
- all return NULL if json_str is NULL
- if json_str is not valid
- json_parse will report error
+ - json_parse_error_to_invalid will return NULL
- json_parse_error_to_null will return NULL
- json_parse_error_to_value will return the value specified by
default_json_str
+ - json_parse_notnull will return NULL

+## Return Values
+According to the type of the field to be extracted, return the data type of
the specified JSON_PATH in the target JSON. Special case handling is as follows:
+* If the field specified by json_path does not exist in the JSON, return NULL.
+* If the actual type of the field specified by json_path in the JSON is
inconsistent with the type specified by json_extract_t.
+* if it can be losslessly converted to the specified type, return the
specified type t; if not, return NULL.
-Exception handling is as follows:
-- if the field specified by json_path does not exist, return NULL
-- if datatype of the field specified by json_path is not the same with type of
json_extract_t, return t if it can be cast to t else NULL

string is not a valid JSON string.

+JSON_EXTRACT is a series of functions that extract the field specified by
json_path from JSON data and provide different series of functions according to
the type of the field to be extracted.
+
+* JSON_EXTRACT returns the VARCHAR type for a json string of the VARCHAR type.
+* JSON_EXTRACT_ISNULL returns the BOOLEAN type indicating whether it is a json
null.
+* JSON_EXTRACT_BOOL returns the BOOLEAN type.
+* JSON_EXTRACT_INT returns the INT type.
+* JSON_EXTRACT_BIGINT returns the BIGINT type.
+* JSON_EXTRACT_LARGEINT returns the LARGEINT type.
+* JSON_EXTRACT_DOUBLE returns the DOUBLE type.
+* JSON_EXTRACT_STRING returns the STRING type.

-## json_parse
-### description
-#### Syntax
+## Description
+Parse the original JSON string into JSON binary format. To meet the needs of
different abnormal data processing, different JSON_PARSE series functions are
provided as follows:
+* JSON_PARSE: Parse the JSON string, and report an error when the input string
is not a valid JSON string.
+* JSON_PARSE_ERROR_TO_INVALID: Parse the JSON string, and return NULL when the
input string is not a valid JSON string.
+* JSON_PARSE_ERROR_TO_NULL: Parse the JSON string, and return NULL when the
input string is not a valid JSON string.
+* JSON_PARSE_ERROR_TO_VALUE: Parse the JSON string, and return the default
value specified by the parameter default_json_str when the input string is not
a valid JSON string.
+* JSON_PARSE_NOTNULL: Parse the JSON string, and return NULL when the input
string is not a valid JSON string.
+## Alias
+* JSONB_PARSE is the same as JSON_PARSE
+* JSONB_PARSE_ERROR_TO_INVALID is the same as JSON_PARSE_ERROR_TO_INVALID
+* JSONB_PARSE_ERROR_TO_NULL is the same as JSON_PARSE_ERROR_TO_NULL
+* JSONB_PARSE_ERROR_TO_VALUE is the same as JSON_PARSE_ERROR_TO_VALUE
+* JSONB_PARSE_NOTNULL is the same as JSON_PARSE_NOTNULL
+
+## Syntax
+
+```sql
+JSON_PARSE (<json_str>)
+```
+```sql
+JSON_PARSE_ERROR_TO_INVALID (<json_str>)
+```
+```sql

```
+## Parameters
+| Parameter | Description |
+|--------------|-----------------------------|
+| `<json_str>` | The JSON type parameter or field to be extracted. |
+| `<default_json_str>` | When the input string is not a valid JSON string,
return the default value specified by the parameter default_json_str. |
|
+
+## Return Values
json_parse functions parse JSON string to binary format. A series of functions
are provided to satisfy different demand for exception handling.
- all return NULL if json_str is NULL
- if json_str is not valid
- json_parse will report error
+ - json_parse_error_to_invalid will return NULL
- json_parse_error_to_null will return NULL
- json_parse_error_to_value will return the value specified by
default_json_str
