MySQL 5.7.8 ve sonraki s\u00fcr\u00fcmler, JSON (JavaScript Object Notation) veri t\u00fcr\u00fcn\u00fc destekler. Bu \u00f6zellik, JSON format\u0131ndaki verileri veritaban\u0131nda saklamay\u0131 ve bu veriler \u00fczerinde \u00e7e\u015fitli i\u015flemler yapmay\u0131 kolayla\u015ft\u0131r\u0131r. Bu yaz\u0131da, MySQL'de JSON veri t\u00fcr\u00fcn\u00fcn nas\u0131l kullan\u0131laca\u011f\u0131n\u0131, JSON verilerinin nas\u0131l eklenece\u011fini, g\u00fcncellenece\u011fini ve nas\u0131l \u00e7\u0131kar\u0131laca\u011f\u0131n\u0131 ele alaca\u011f\u0131z.<\/p>
#### 1. JSON Veri T\u00fcr\u00fc ile Tablo Olu\u015fturma<\/p>
JSON veri t\u00fcr\u00fc, bir tabloda JSON format\u0131nda veri saklamak i\u00e7in kullan\u0131l\u0131r. A\u015fa\u011f\u0131daki \u00f6rnekte, birincil anahtar ve JSON s\u00fctunu i\u00e7eren bir tablo olu\u015fturulmu\u015ftur:<\/p>
```sql
CREATE TABLE table_name (
id INT NOT NULL AUTO_INCREMENT,
json_col JSON,
PRIMARY KEY(id)
);
```<\/p>
#### 2. JSON Verisi Ekleme<\/p>
JSON verisi, bir tabloya eklenirken JSON format\u0131nda bir dize olarak belirtilir. JSON anahtarlar\u0131 \u00e7ift t\u0131rnak i\u00e7inde olmal\u0131d\u0131r.<\/p>
##### \u00d6rnek: Basit JSON Verisi Ekleme<\/p>
```sql
INSERT INTO table_name (json_col)
VALUES ('{\"city\": \"Galle\", \"Description\": \"Best damn city in the world\"}');
```<\/p>
Bu \u00f6rnekte, `json_col` s\u00fctununa bir JSON nesnesi eklenmi\u015ftir.<\/p>
#### 3. JSON Verisini G\u00fcncelleme<\/p>
JSON verisini g\u00fcncellemek i\u00e7in `JSON_ARRAY_APPEND`, `JSON_SET` gibi JSON fonksiyonlar\u0131 kullan\u0131l\u0131r.<\/p>
##### \u00d6rnek: JSON Dizisine Eleman Ekleme<\/p>
A\u015fa\u011f\u0131daki \u00f6rnekte, `variations` dizisine yeni bir eleman eklenmi\u015ftir:<\/p>
```sql
UPDATE myjson
SET dict = JSON_ARRAY_APPEND(dict, '$.variations', 'scheveningen')
WHERE id = 2;
```<\/p>
**Sonu\u00e7:**
```
+---+---+
| id | dict |
+---+---+
| 2 | {\"opening\": \"Sicilian\", \"variations\": } |
+---+---+
```<\/p>
#### 4. JSON Verisini CAST ile D\u00f6n\u00fc\u015ft\u00fcrme<\/p>
JSON format\u0131ndaki bir dizeyi JSON veri t\u00fcr\u00fcne d\u00f6n\u00fc\u015ft\u00fcrmek i\u00e7in `CAST` fonksiyonu kullan\u0131l\u0131r.<\/p>
##### \u00d6rnek: JSON Dizesini JSON T\u00fcr\u00fcne D\u00f6n\u00fc\u015ft\u00fcrme<\/p>
```sql
SELECT CAST('' AS JSON);
SELECT CAST('{\"opening\":\"Sicilian\",\"variations\":}' AS JSON);
```<\/p>
#### 5. JSON Nesnesi ve Dizisi Olu\u015fturma<\/p>
`JSON_OBJECT` ve `JSON_ARRAY` fonksiyonlar\u0131 ile JSON nesneleri ve dizileri olu\u015fturulabilir.<\/p>
##### \u00d6rnek: JSON Nesnesi ve Dizisi Olu\u015fturma<\/p>
```sql
SELECT JSON_OBJECT('key1', col1, 'key2', col2, 'key3', 'col3') AS myobj;
SELECT JSON_ARRAY(col1, col2, 'col3') AS myarray;
```<\/p>
Kar\u0131\u015f\u0131k JSON verisi olu\u015fturmak i\u00e7in:<\/p>
```sql
SELECT JSON_OBJECT(\"opening\", \"Sicilian\", \"variations\", JSON_ARRAY(\"pelikan\", \"dragon\", \"najdorf\")) AS mymixed;
```<\/p>
#### 6. JSON Verisinden De\u011fer \u00c7\u0131karma<\/p>
JSON verisinden belirli de\u011ferleri \u00e7\u0131karmak i\u00e7in `JSON_EXTRACT` fonksiyonu veya `->`, `->>` operat\u00f6rleri kullan\u0131l\u0131r.<\/p>
##### \u00d6rnek: JSON Dizisinden De\u011fer \u00c7\u0131karma<\/p>
```sql
SET @myjson = CAST('' AS JSON);<\/p>
SELECT
JSON_EXTRACT(@myjson, '$'),
JSON_EXTRACT(@myjson, '$.label'),
JSON_EXTRACT(@myjson, '$.*'),
JSON_EXTRACT(@myjson, '$.*');
```<\/p>
**Sonu\u00e7:**
```
+---+---+
| JSON_EXTRACT(@myjson, '$') | JSON_EXTRACT(@myjson, '$.label') | JSON_EXTRACT(@myjson, '$.*') | JSON_EXTRACT(@myjson, '$.*') |
+---+---+
| {\"id\": 1, \"label\": \"C\"} | | | NULL |
+---+---+
```<\/p>
##### \u00d6rnek: JSON Operat\u00f6rleri ile De\u011fer \u00c7\u0131karma<\/p>
```sql
SELECT
myjson_col->>'$',
myjson_col->'$',
myjson_col->>'$.label',
myjson_col->>'$.*',
myjson_col->>'$.*'
FROM tablename;
```<\/p>
**Sonu\u00e7:**
```
+---+---+
| myjson_col->>'$' | myjson_col->'$' | myjson_col->>'$.label' | myjson_col->>'$.*' | myjson_col->>'$.*' |
