php联接访Oracle是用过oci函数
php连接访Oracle是用过oci函数
php连接访Oracle是用过oci函数,以下是整理的文档
1.安装Apache和php包
yum install -y httpd php*
2.下载Oracle组件
oracle-instantclient-basic-10.2.0.4-1.i386.rpm
oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm
oracle-instantclient-devel-10.2.0.4-1.i386.rpm
oracle-instantclient-odbc-10.2.0.4-1.i386.rpm
#rpm -ivh oracle-instantclient*(四个组件全部安装上)
此时会生成/usr/lib/oracle/10.2.0.4/client/lib/目录
3.修改/etc/ld.so.conf文件
#vim /etc/ld.so.conf
追加以下内容
/usr/lib/oracle/10.2.0.4/client/lib/
#ldconfig(执行命令)
4.下载OCI8组件
http://pecl.php.net/get/oci8-1.4.1.tgz
#tar zxvf oci8-1.4.1.tgz
5.编辑OCI8模块
#cd oci8-1.4.1
#phpize(执行命令)
#./configure --with-oci8=instantclient,/usr/lib/oracle/10.2.0.4/client/lib/
#make install
成功后系统会提示你:oci8.so已经成功放入/usr/lib/php/modules/目录中
6.修改php.ini文件
#vim /etc/php.ini
追加以下内容
extension=oci8.so
7.重启Apache服务
service httpd restart
8.使用phpinfo()函数查看
码连接测试Oracle数据库
- php
- $conn = oci_connect('scott', 'oracle', '192.168.12.133/orcl');
- if (!$conn) {
- $e = oci_error();
- print htmlentities($e['message']);
- exit;
- }
- $query = 'select ename,sal from scott.emp';
- $stid = oci_parse($conn, $query);
- if (!$stid) {
- $e = oci_error($conn);
- print htmlentities($e['message']);
- exit;
- }
- $r = oci_execute($stid, OCI_DEFAULT);
- if(!$r) {
- $e = oci_error($stid);
- echo htmlentities($e['message']);
- exit;
- }
- print 'table border="1">';
- while($row = oci_fetch_array($stid, OCI_RETURN_NULLS)) {
- print 'tr>';
- foreach($row as $item) {
- print 'td>'.($item?htmlentities($item):' ').'td>';
- }
- print 'tr>';
- }
- print 'table>';
- oci_close($conn);
- ?>

Data import method: 1. Use the SQLLoader utility: prepare data files, create control files, and run SQLLoader; 2. Use the IMP/EXP tool: export data, import data. Tip: 1. Recommended SQL*Loader for big data sets; 2. The target table should exist and the column definition matches; 3. After importing, data integrity needs to be verified.

Creating an Oracle table involves the following steps: Use the CREATE TABLE syntax to specify table names, column names, data types, constraints, and default values. The table name should be concise and descriptive, and should not exceed 30 characters. The column name should be descriptive, and the data type specifies the data type stored in the column. The NOT NULL constraint ensures that null values are not allowed in the column, and the DEFAULT clause specifies the default values for the column. PRIMARY KEY Constraints to identify the unique record of the table. FOREIGN KEY constraint specifies that the column in the table refers to the primary key in another table. See the creation of the sample table students, which contains primary keys, unique constraints, and default values.

To query the Oracle tablespace size, follow the following steps: Determine the tablespace name by running the query: SELECT tablespace_name FROM dba_tablespaces; Query the tablespace size by running the query: SELECT sum(bytes) AS total_size, sum(bytes_free) AS available_space, sum(bytes) - sum(bytes_free) AS used_space FROM dba_data_files WHERE tablespace_

Use the ALTER TABLE statement, the specific syntax is as follows: ALTER TABLE table_name ADD column_name data_type [constraint-clause]. Where: table_name is the table name, column_name is the field name, data_type is the data type, and constraint-clause is an optional constraint. Example: ALTER TABLE employees ADD email VARCHAR2(100) Add an email field to the employees table.

Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.

Oracle garbled problems can be solved by checking the database character set to ensure they match the data. Set the client character set to match the database. Convert data or modify column character sets to match database character sets. Use Unicode character sets and avoid multibyte character sets. Check that the language settings of the database and client are correct.

Oracle provides multiple deduplication query methods: The DISTINCT keyword returns a unique value for each column. The GROUP BY clause groups the results and returns a non-repetitive value for each group. The UNIQUE keyword is used to create an index containing only unique rows, and querying the index will automatically deduplicate. The ROW_NUMBER() function assigns unique numbers and filters out results that contain only line 1. The MIN() or MAX() function returns non-repetitive values of a numeric column. The INTERSECT operator returns the common values of the two result sets (no duplicates).

Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.
