Tags: Oracle DML error logThe DML error log is a sql*loader-like error logging feature introduced by ORACLE10GR2. The rationale for this is to transfer any records that might cause the statement to fail and put them in an error log table.The specific use is as follows:1, use Dbms_errlog.

When creating a webpage homepage, if you want to use slideshow [1] for image switching, it is okay to test the page properly: When the browser opens multiple tabs at the same time, after staying on the page in his tab for a while, the picture will be the last image. To solve this problem, this article provides a detailed solution. If you are interested, you can find out.

the length of the data type. The stored characters are of the Unicode encoding type. Each character occupies two bytes. n indicates the data that can be stored.Maximum number of characters(Value range: 1 ~ 4000 [think about why the maximum value is 4000 ?]), When the number of characters to be saved is less than n, there are insufficient spaces at the end. When the number of characters stored exceeds n, th

The clob field stores text. If less than 4000 bytes are stored, the clob field is stored together with the recording. If more than 4000 bytes are stored, it is not stored together with the record. It is worth noting that the 4000 bytes here are not equivalent to varchar2 (4000). What is the equivalent? Please refer to

, varchar, and ntext Data Types in SQL Server. This data type can be used for columns that store characters from multiple character sets. The nvarchar type is used when the number of Unicode characters in each column is different (up to 4000. When each item in a column has a fixed length (up to 4000 Unicode characters), The nchar type is used. When any item in the column exceeds

) provides a simple solution for LAN Internet sharing. When an intranet user connects to the Internet, Nat converts the user's internal IP address into an external public IP address. Otherwise, when data is returned from outside, Nat reversely replaces the destination address with the address of the initial internal user. In fact, Nat hides the internal IP address and forms a natural firewall. Return to the preceding example. The vro itself has two IP addresses, one Intranet IP Address: 192.168.

We know that only one byte is required for English characters, but there are many Chinese characters and two bytes are required for storage. It is easy to cause confusion when both English and Chinese characters exist, unicode Character Set is generated to solve the incompatibility problem of character sets. All its characters are expressed in two bytes, that is, English characters are also ex

See the followingCode: VaR STR = 'aaa'; var num = 2; function auto (Num) {alert (Num);} setTimeout ('Auto (Num) ', 4000 ); In this way, the write operation works normally, but if it is said that this is a parameter transfer, it is better to say that it is a directly used global variable. Therefore, this writing method is unnecessary. Generally, it is used to pass local variables as parameters. Modify the Code: // Var STR = 'aaa'; var num =

Oracle DML Error Log notes DML error log is an error log function introduced by Oracle 10gR2 similar to SQL * Loader. The basic principle is to transfer any records that may cause statement failure to an error log table. The specific usage is as follows: 1. Use DBMS_ERRLOG.CREATE_ERROR_LOG to create an error log table. -- My_test table structure of the original table Desc my_test Name Type Nullable Default Comments ----------------------------------------- SID NUMBER NAME VARCHAR2 (20) Y GENDER
