Pada artikel ini, saya memberikan contoh untuk mengekspor data ke file JSON di Oracle 11g menggunakan PL/SQL.
Ikuti Langkah-Langkah Ini untuk Mengekspor Data ke File JSON di Oracle 11g
- Pertama, unduh paket utilitas Alexandria PL/SQL dari GITHUB menggunakan tautan berikut:Unduh paket alexandria_plsql_utility.
- Setelah mengunduh file zip, ekstrak dan temukan JSON_UTIL_PKG di direktori "alexandria-plsql-utils-master\alexandria-plsql-utils-master\ora".
- Instal spesifikasi dan isi paket JSON_UTIL_PKG ke dalam skema Anda
- Setelah itu unduh prosedur PL/SQL "WRITE_CLOB_TO_FILE" dari tautan berikut:Unduh Write_Clob_To_File.
- Instal prosedur ini juga ke dalam skema Anda.
Sekarang Anda dapat membuat file JSON dari tabel Oracle menggunakan PL/SQL, seperti yang ditunjukkan pada contoh di bawah ini.
Contoh Oracle 11g SQL ke JSON
Pada contoh berikut, kita akan memasukkan data ke dalam variabel CLOB menggunakan fungsi JSON_UTIL_PKG.SQL_TO_JSON dan kemudian kita akan menulis bahwa CLOB memiliki data JSON ke dalam FILE menggunakan prosedur WRITE_CLOB_TO_FILE . Kami akan meneruskan tiga parameter ke prosedur WRITE_CLOB_TO_FILE, dan mereka adalah sebagai berikut:nama file, nama objek direktori, dan variabel CLOB.
DECLARE
c CLOB;
BEGIN
SELECT json_util_pkg.sql_to_json('select EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO from emp2')
INTO c
FROM DUAL;
WRITE_CLOB_TO_FILE ('emp.json', 'JSON_DIR', c);
END;
/ Sekarang Anda dapat memeriksa lokasi objek direktori JSON_DIR, dan Anda akan menemukan file JSON seperti yang ditunjukkan pada contoh output di bawah ini:
{"ROWSET":[{"EMPNO":7369,"ENAME":"SMITH","JOB":"CLERK","MGR":7902,"HIREDATE":"17-DEC-80","SAL":800,"COMM":null,"DEPTNO":21},{"EMPNO":7499,"ENAME":"ALLEN","JOB":"SALESMAN","MGR":7698,"HIREDATE":"20-FEB-81","SAL":1600,"COMM":300,"DEPTNO":30},{"EMPNO":7521,"ENAME":"WARD","JOB":"SALESMAN","MGR":7698,"HIREDATE":"22-FEB-81","SAL":1250,"COMM":500,"DEPTNO":30},{"EMPNO":7566,"ENAME":"JONES","JOB":"MANAGER","MGR":7839,"HIREDATE":"04-FEB-81","SAL":2975,"COMM":null,"DEPTNO":20},{"EMPNO":7654,"ENAME":"MARTIN","JOB":"SALESMAN","MGR":7698,"HIREDATE":"28-SEP-81","SAL":1250,"COMM":1400,"DEPTNO":30},{"EMPNO":7698,"ENAME":"BLAKE","JOB":"MANAGER","MGR":7839,"HIREDATE":"05-JAN-81","SAL":2850,"COMM":null,"DEPTNO":30},{"EMPNO":7782,"ENAME":"CLARK","JOB":"MANAGER","MGR":7839,"HIREDATE":"06-SEP-81","SAL":2450,"COMM":null,"DEPTNO":10},{"EMPNO":7788,"ENAME":"SCOTT","JOB":"ANALYST","MGR":7566,"HIREDATE":"19-APR-87","SAL":3000,"COMM":null,"DEPTNO":20},{"EMPNO":7839,"ENAME":"KING","JOB":"PRESIDENT","MGR":null,"HIREDATE":"17-NOV-81","SAL":5000,"COMM":null,"DEPTNO":10},{"EMPNO":7844,"ENAME":"TURNER","JOB":"SALESMAN","MGR":7698,"HIREDATE":"09-AUG-81","SAL":1500,"COMM":0,"DEPTNO":30},{"EMPNO":7876,"ENAME":"ADAMS","JOB":"CLERK","MGR":7788,"HIREDATE":"23-MAY-87","SAL":1100,"COMM":null,"DEPTNO":20},{"EMPNO":7900,"ENAME":"JAMES","JOB":"CLERK","MGR":7698,"HIREDATE":"12-MAR-81","SAL":950,"COMM":null,"DEPTNO":30},{"EMPNO":7902,"ENAME":"FORD","JOB":"ANALYST","MGR":7566,"HIREDATE":"12-MAR-81","SAL":3000,"COMM":null,"DEPTNO":20},{"EMPNO":7934,"ENAME":"MILLER","JOB":"CLERK","MGR":7782,"HIREDATE":"23-JAN-82","SAL":1300,"COMM":null,"DEPTNO":10}]} Lihat juga:
