Oracle XE(或者"Oracle Database 10g Express Edition")是一个简单免费发布的版本。
以下是语法格式:
Driver=(Oracle in XEClient);dbq=111.21.31.99:1521/XE;Uid=myUsername;Pwd=myPassword; |
ODBC
新版本连接方式
以下是语法格式:
Driver={Microsoft ODBC for Oracle};Server=myServerAddress;Uid=myUsername;Pwd=myPassword; |
老版本连接方式
以下是语法格式:
Driver={Microsoft ODBC Driver for Oracle};ConnectString=OracleServer.world;Uid=myUsername;Pwd=myPassword; |
OLE DB, OleDbConnection (.NET)
标准安全连接
此连接方式使用来自微软的Provider。
以下是语法格式:
Provider=msdaora;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword; |
信任连接
以下是语法格式:
Provider=msdaora;Data Source=MyOracleDB;Persist Security Info=False;Integrated Security=Yes; |
标准安全连接
此连接方式使用来自Oracle的Provider。
以下是语法格式:
Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword; |
信任连接
以下是语法格式:
Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;OSAuthent=1; |
以下是语法格式:
Provider=OraOLEDB.Oracle;Data Source=(DESCRIPTION=(CID=GTU_APP)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=myHost)(PORT=myPort)))(CONNECT_DATA=(SID=MyOracleSID)(SERVER=DEDICATED)));User Id=myUsername;Password=myPassword; |
Oracle.DataAccess.Client.OracleConnection
标准连接
以下是语法格式:
Data Source=TORCL;User Id=myUsername;Password=myPassword; |
带integrated security的连接
以下是语法格式:
Data Source=TORCL;Integrated Security=SSPI; |
带 ODP.NET 不带 tnsnames.ora的连接
以下是语法格式:
Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword; |
OracleConnection, Oracle Data Provider, ODP.NET, System.Data.OracleClient.OracleConnection
标准连接
以下是语法格式:
Data Source=MyOracleDB;Integrated Security=yes |
仅在Oracle8i release 3 或更高版本
指明用户密与密码的连接
以下是语法格式:
Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;Integrated Security=no; |
这是另一种连接方式不依赖你的DNS.You create a connection string based on the format used in the tnsnames.ora file without the need to actually have one of these files on the client pc.
以下是语法格式:
SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));uid=myUsername;pwd=myPassword; |
Some reported problems with the one above and Visual Studio. Use the next one if you've encountered problems.
以下是语法格式:
Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword; |
使用连接池
连接池服务如果找不到一个完全匹配连接字符串的连接,他将会创建一个。如果能找到该连接,将会重新使用。
以下是语法格式:
Data Source=myOracleDB;User Id=myUsername;Password=myPassword;Min Pool Size=10;Connection Lifetime=120;Connection Timeout=60;Incr Pool Size=5;Decr Pool Size=2; |
Windows验证
以下是语法格式:
Data Source=myOracleDB;User Id=/; |
特权连接
使用SYSOPER的特权
以下是语法格式:
Data Source=myOracleDB;User Id=SYS;Password=SYS;DBA Privilege=SYSOPER; |
利用密码终止函数
当第一次打开连接时,当打开链接后,一个密码过期错误被抛出,捕获这个错误并执行OpenWithNewPassword命令行设置新密码。
以下是语法格式:
Data Source=myOracleDB;User Id=myUsername;Password=myPassword; |
代理验证
以下是语法格式:
|
Core Labs OraDirect (.NET)
标准连接
以下是语法格式:
User ID=myUsername;Password=myPassword;Host=ora;Pooling=true;Min Pool Size=0;Max Pool Size=100;Connection Lifetime=0; |
Data Shape
MS Data Shape
以下是语法格式:
Provider=MSDataShape.1;Persist Security Info=False;Data Provider=MSDAORA;Data Source=orac;User Id=myUsername;Password=myPassword; |

The retention period of Oracle database logs depends on the log type and configuration, including: Redo logs: determined by the maximum size configured with the "LOG_ARCHIVE_DEST" parameter. Archived redo logs: Determined by the maximum size configured by the "DB_RECOVERY_FILE_DEST_SIZE" parameter. Online redo logs: not archived, lost when the database is restarted, and the retention period is consistent with the instance running time. Audit log: Configured by the "AUDIT_TRAIL" parameter, retained for 30 days by default.

The function in Oracle to calculate the number of days between two dates is DATEDIFF(). The specific usage is as follows: Specify the time interval unit: interval (such as day, month, year) Specify two date values: date1 and date2DATEDIFF(interval, date1, date2) Return the difference in days

The Oracle database startup sequence is: 1. Check the preconditions; 2. Start the listener; 3. Start the database instance; 4. Wait for the database to open; 5. Connect to the database; 6. Verify the database status; 7. Enable the service (if necessary ); 8. Test the connection.

The INTERVAL data type in Oracle is used to represent time intervals. The syntax is INTERVAL <precision> <unit>. You can use addition, subtraction, multiplication and division operations to operate INTERVAL, which is suitable for scenarios such as storing time data and calculating date differences.

To find the number of occurrences of a character in Oracle, perform the following steps: Get the total length of a string; Get the length of the substring in which a character occurs; Count the number of occurrences of a character by subtracting the substring length from the total length.

Oracle database server hardware configuration requirements: Processor: multi-core, with a main frequency of at least 2.5 GHz. For large databases, 32 cores or more are recommended. Memory: At least 8GB for small databases, 16-64GB for medium sizes, up to 512GB or more for large databases or heavy workloads. Storage: SSD or NVMe disks, RAID arrays for redundancy and performance. Network: High-speed network (10GbE or higher), dedicated network card, low-latency network. Others: Stable power supply, redundant components, compatible operating system and software, heat dissipation and cooling system.

The amount of memory required by Oracle depends on database size, activity level, and required performance level: for storing data buffers, index buffers, executing SQL statements, and managing the data dictionary cache. The exact amount is affected by database size, activity level, and required performance level. Best practices include setting the appropriate SGA size, sizing SGA components, using AMM, and monitoring memory usage.

The method of replacing strings in Oracle is to use the REPLACE function. The syntax of this function is: REPLACE(string, search_string, replace_string). Usage steps: 1. Identify the substring to be replaced; 2. Determine the new string to replace the substring; 3. Use the REPLACE function to replace. Advanced usage includes: multiple replacements, case sensitivity, special character replacement, etc.
