For Oracle data types are supported

Oracle database in different data types

1, character type CHAR NCHAR VARCHAR VARCHAR2 NVARCHAR2

2, the digital type NUMBER INTEGER

3, the date of type DATE TIMESTAMP

4, binary type BLOB, CLOB, NCLOB, BFILE

5、RAW & LONG RAW类型 ROWID & UROWID

 

Data type included in the current system

select distinct data_type from user_tab_cols
 

LONG NVARCHAR2 TIMESTAMP(6) FLOAT NUMBER CHAR CLOB NCHAR DATE RAW VARCHAR2 BLOB

A total of 12, a check for each data type, the system is not really look contain meaningful data, or the data types are defined in the table structure, and never stored record meaningful values .

select *  from user_tab_cols t where t.DATA_TYPE ='LONG';

You can get

Such a table, we were to find where each side of the table, the table to see if there are data records, which in this field is not entirely empty value, as long as a true rms, then the data will need to be included in our content to be tested.

How we will deal with a variety of different types of systems, the means to be adopted into four

A, the interface does not show

B, do not let the interface editor

C, if the modified content illegal, judge trigger conditions, use the warning color, and can not be prompted to enter the list to be submitted

D, at the time of submission of the final, was checking out.

 

 

1, character type CHAR NCHAR VARCHAR VARCHAR2 NVARCHAR2

We need to support

2, the digital type NUMBER INTEGER

We need to support

3, the date of type DATE TIMESTAMP

We need support, the support of the timestamp of the doubt

4, binary type BLOB, CLOB, NCLOB, BFILE

CLOB may be able to support the other should not support editing

5, RAW & LONG RAW type

not support

6、 ROWID & UROWID

It does not support, the interface does not show
