The path-value pairs are evaluated left to right. The document produced by evaluating one pair becomes the new value against which the next pair is evaluated. Pairs for which the path does not identify any array in the JSON document are ignored. If a path identifies an array element, the corresponding value is inserted at that element position, shifting any following values to the right. If a path identifies an array position past the end of an array, the value is inserted at the end of the array.

}

JSON_CONTAINS(target, candidate[, path])

JSONContains indicates by returning 1 or 0 whether a given candidate JSON document is contained within a target JSON document, or, if a path argument was supplied, whether the candidate is found at a specific path within the target. Returns NULL if any argument is NULL, or if the path argument does not identify a section of the target document. An error occurs if target or candidate is not a valid JSON document, or if the path argument is not a valid path expression or contains a * or ** wildcard. To check only whether any data exists at the path, use JSON_CONTAINS_PATH() instead.

The following rules define containment:

• A candidate scalar is contained in a target scalar if and only if they are comparable and are equal. Two scalar values are comparable if they have the same JSON_TYPE() types, with the exception that values of types INTEGER and DECIMAL are also comparable to each other.
• A candidate array is contained in a target array if and only if every element in the candidate is contained in some element of the target.
• A candidate non-array is contained in a target array if and only if the candidate is contained in some element of the target.
• A candidate object is contained in a target object if and only if for each key in the candidate there is a key with the same name in the target and the value associated with the candidate key is contained in the value associated with the target key.

Otherwise, the candidate value is not contained in the target document.

An error occurs if the json_doc argument is not a valid JSON document, any path argument is not a valid path expression, or one_or_all is not 'one' or 'all'. To check for a specific value at a path, use JSON_CONTAINS() instead.

The return value is 0 if no specified path exists within the document. Otherwise, the return value depends on the one_or_all argument:

• 'one': 1 if at least one path exists within the document, 0 otherwise.
• 'all': 1 if all paths exist within the document, 0 otherwise.

JSON_INSERT(json_doc, path, val[, path, val] ...)

JSONInsert Inserts data into a JSON document and returns the result. Returns NULL if any argument is NULL. An error occurs if the json_doc argument is not a valid JSON document or any path argument is not a valid path expression or contains a * or ** wildcard. The path-value pairs are evaluated left to right. The document produced by evaluating one pair becomes the new value against which the next pair is evaluated. A path-value pair for an existing path in the document is ignored and does not overwrite the existing document value. A path-value pair for a nonexisting path in the document adds the value to the document if the path identifies one of these types of values:

• A member not present in an existing object. The member is added to the object and associated with the new value.
• A position past the end of an existing array. The array is extended with the new value. If the existing value is not an array, it is autowrapped as an array, then extended with the new value.

Otherwise, a path-value pair for a nonexisting path in the document is ignored and has no effect.

Returns NULL if any argument is NULL, the json_doc argument is not an object, or path, if given, does not locate an object. An error occurs if the json_doc argument is not a valid JSON document or the path argument is not a valid path expression or contains a * or ** wildcard. The result array is empty if the selected object is empty. If the top-level value has nested subobjects, the return value does not include keys from those subobjects.

type JSONMerge

type JSONMerge struct {
	sql.Expression
}

JSON_MERGE(json_doc, json_doc[, json_doc] ...)

JSONMerge Merges two or more JSON documents. Synonym for JSONMergePreserve(); deprecated in MySQL 8.0.3 and subject to removal in a future release.

https://dev.mysql.com/doc/refman/8.0/en/json-modification-functions.html#function_json-merge

type JSONMergePatch

type JSONMergePatch struct {
	sql.Expression
}

JSON_MERGE_PATCH(json_doc, json_doc[, json_doc] ...)

JSONMergePatch Performs an RFC 7396 compliant merge of two or more JSON documents and returns the merged result, without preserving members having duplicate keys. Raises an error if at least one of the documents passed as arguments to this function is not valid. JSONMergePatch performs a merge as follows:

• If the first argument is not an object, the result of the merge is the same as if an empty object had been merged with the second argument.
• If the second argument is not an object, the result of the merge is the second argument.
• If both arguments are objects, the result of the merge is an object with the following members:
• All members of the first object which do not have a corresponding member with the same key in the second object.
• All members of the second object which do not have a corresponding key in the first object, and whose value is not the JSON null literal.
• All members with a key that exists in both the first and the second object, and whose value in the second object is not the JSON null literal. The values of these members are the results of recursively merging the value in the first object with the value in the second object.

The behavior of JSONMergePatch is the same as that of JSONMergePreserve, with the following two exceptions:

• JSONMergePatch removes any member in the first object with a matching key in the second object, provided that the value associated with the key in the second object is not JSON null.
• If the second object has a member with a key matching a member in the first object, JSONMergePatch replaces the value in the first object with the value in the second object, whereas JSONMergePreserve appends the second value to the first value.

JSON_OVERLAPS(json_doc1, json_doc2)

JSONOverlaps Compares two JSON documents. Returns true (1) if the two document have any key-value pairs or array elements in common. If both arguments are scalars, the function performs a simple equality test.

This function serves as counterpart to JSON_CONTAINS(), which requires all elements of the array searched for to be present in the array searched in. Thus, JSON_CONTAINS() performs an AND operation on search keys, while JSON_OVERLAPS() performs an OR operation.

Queries on JSON columns of InnoDB tables using JSON_OVERLAPS() in the WHERE clause can be optimized using multi-valued indexes. Multi-Valued Indexes, provides detailed information and examples.

type JSONPretty

type JSONPretty struct {

JSON_PRETTY(json_val)

JSONPretty Provides pretty-printing of JSON values similar to that implemented in PHP and by other languages and database systems. The value supplied must be a JSON value or a valid string representation of a JSON value. Extraneous whitespaces and newlines present in this value have no effect on the output. For a NULL value, the function returns NULL. If the value is not a JSON document, or if it cannot be parsed as one, the function fails with an error. Formatting of the output from this function adheres to the following rules:

• Each array element or object member appears on a separate line, indented by one additional level as compared to its parent.
• Each level of indentation adds two leading spaces.
• A comma separating individual array elements or object members is printed before the newline that separates the two elements or members.
• The key and the value of an object member are separated by a colon followed by a space (': ').
• An empty object or array is printed on a single line. No space is printed between the opening and closing brace.
• Special characters in string scalars and key names are escaped employing the same rules used by JSONQuote.

JSON_QUOTE(string)

JSONQuote Quotes a string as a JSON value by wrapping it with double quote characters and escaping interior quote and other characters, then returning the result as a utf8mb4 string. Returns NULL if the argument is NULL. This function is typically used to produce a valid JSON string literal for inclusion within a JSON document. Certain special characters are escaped with backslashes per the escape sequences shown in Table 12.23, “JSON_UNQUOTE() Special Character Escape Sequences”: https://dev.mysql.com/doc/refman/8.0/en/json-modification-functions.html#json-unquote-character-escape-sequences

type JSONRemove

type JSONRemove struct {

JSON_REMOVE(json_doc, path[, path] ...)

JSONRemove Removes data from a JSON document and returns the result. Returns NULL if any argument is NULL. An error occurs if the json_doc argument is not a valid JSON document or any path argument is not a valid path expression or is $ or contains a * or ** wildcard. The path arguments are evaluated left to right. The document produced by evaluating one path becomes the new value against which the next path is evaluated. It is not an error if the element to be removed does not exist in the document; in that case, the path does not affect the document.

JSON_REPLACE(json_doc, path, val[, path, val] ...)

JSONReplace Replaces existing values in a JSON document and returns the result. Returns NULL if any argument is NULL. An error occurs if the json_doc argument is not a valid JSON document or any path argument is not a valid path expression or contains a * or ** wildcard. The path-value pairs are evaluated left to right. The document produced by evaluating one pair becomes the new value against which the next pair is evaluated. A path-value pair for an existing path in the document overwrites the existing document value with the new value. A path-value pair for a non-existing path in the document is ignored and has no effect.

JSON_SCHEMA_VALIDATION_REPORT(schema,document)

JSONSchemaValidationReport Validates a JSON document against a JSON schema. Both schema and document are required. As with JSONSchemaValid, the schema must be a valid JSON object, and the document must be a valid JSON document. Provided that these conditions are met, the function returns a report, as a JSON document, on the outcome of the validation. If the JSON document is considered valid according to the JSON Schema, the function returns a JSON object with one property valid having the value "true". If the JSON document fails validation, the function returns a JSON object which includes the properties listed here:

• valid: Always "false" for a failed schema validation
• reason: A human-readable string containing the reason for the failure
• schema-location: A JSON pointer URI fragment identifier indicating where in the JSON schema the validation failed (see Note following this list)
• document-location: A JSON pointer URI fragment identifier indicating where in the JSON document the validation failed (see Note following this list)
• schema-failed-keyword: A string containing the name of the keyword or property in the JSON schema that was violated

type JSONSearch

type JSONSearch struct {
	sql.Expression
}

JSON_SEARCH(json_doc, one_or_all, search_str[, escape_char[, path] ...])

JSONSearch Returns the path to the given string within a JSON document. Returns NULL if any of the json_doc, search_str, or path arguments are NULL; no path exists within the document; or search_str is not found. An error occurs if the json_doc argument is not a valid JSON document, any path argument is not a valid path expression, one_or_all is not 'one' or 'all', or escape_char is not a constant expression. The one_or_all argument affects the search as follows:

• 'one': The search terminates after the first match and returns one path string. It is undefined which match is considered first.
• 'all': The search returns all matching path strings such that no duplicate paths are included. If there are multiple strings, they are autowrapped as an array. The order of the array elements is undefined.

Within the search_str search string argument, the % and _ characters work as for the LIKE operator: % matches any number of characters (including zero characters), and _ matches exactly one character.

To specify a literal % or _ character in the search string, precede it by the escape character. The default is \ if the escape_char argument is missing or NULL. Otherwise, escape_char must be a constant that is empty or one character. For more information about matching and escape character behavior, see the description of LIKE in Section 12.8.1, “String Comparison Functions and Operators”: https://dev.mysql.com/doc/refman/8.0/en/string-comparison-functions.html For escape character handling, a difference from the LIKE behavior is that the escape character for JSON_SEARCH() must evaluate to a constant at compile time, not just at execution time. For example, if JSON_SEARCH() is used in a prepared statement and the escape_char argument is supplied using a ? parameter, the parameter value might be constant at execution time, but is not at compile time.

type JSONSet

type JSONSet struct {

}

JSON_SET(json_doc, path, val[, path, val] ...)

JSONSet Inserts or updates data in a JSON document and returns the result. Returns NULL if any argument is NULL or path, if given, does not locate an object. An error occurs if the json_doc argument is not a valid JSON document or any path argument is not a valid path expression or contains a * or ** wildcard. The path-value pairs are evaluated left to right. The document produced by evaluating one pair becomes the new value against which the next pair is evaluated. A path-value pair for an existing path in the document overwrites the existing document value with the new value. A path-value pair for a non-existing path in the document adds the value to the document if the path identifies one of these types of values:

• A member not present in an existing object. The member is added to the object and associated with the new value.
• A position past the end of an existing array. The array is extended with the new value. If the existing value is not an array, it is auto-wrapped as an array, then extended with the new value.

Otherwise, a path-value pair for a non-existing path in the document is ignored and has no effect.

type JSONStorageFree

type JSONStorageFree struct {

}

JSON_STORAGE_FREE(json_val)

JSONStorageFree For a JSON column value, this function shows how much storage space was freed in its binary representation after it was updated in place using JSON_SET(), JSON_REPLACE(), or JSON_REMOVE(). The argument can also be a valid JSON document or a string which can be parsed as one—either as a literal value or as the value of a user variable—in which case the function returns 0. It returns a positive, nonzero value if the argument is a JSON column value which has been updated as described previously, such that its binary representation takes up less space than it did prior to the update. For a JSON column which has been updated such that its binary representation is the same as or larger than before, or if the update was not able to take advantage of a partial update, it returns 0; it returns NULL if the argument is NULL. If json_val is not NULL, and neither is a valid JSON document nor can be successfully parsed as one, an error results.

type JSONStorageSize

type JSONStorageSize struct {

JSON_STORAGE_SIZE(json_val)

JSONStorageSize This function returns the number of bytes used to store the binary representation of a JSON document. When the argument is a JSON column, this is the space used to store the JSON document as it was inserted into the column, prior to any partial updates that may have been performed on it afterwards. json_val must be a valid JSON document or a string which can be parsed as one. In the case where it is string, the function returns the amount of storage space in the JSON binary representation that is created by parsing the string as JSON and converting it to binary. It returns NULL if the argument is NULL. An error results when json_val is not NULL, and is not—or cannot be successfully parsed as—a JSON document.
