In the data warehouse, null values are used to indicate conditions in which the actual values are unknown or ambiguous. In a table, if a column in a row does not have a value, it is called null ). For any data-type column, you only need to use the non-null (not null) or primary key to finish the integer restriction, can be empty. In practice, if a null value is stored, it will become unnecessary. ---- For example, in the following employee table (EMP), the employee name (ename) is King's Row, b

This is the general tutorial, but if you think more, you will find a fatal problem. In practice, it is very likely that this writing method will appear: varchar2 (1400 char).

Oracle in the database, null values are used to indicate a situation where the actual value is unknown or meaningless. In a table, if a column in a row has no value, it is called a null value (NULL). Columns of any data type can have null values if they do not use non-null (not NULL) or primary key (PRIMARY key) integrity restrictions. In practical application, if the existence of NULL value is ignored, it will cause unnecessary trouble. ----For example, in the following employee table (EMP), th

Use the mobile tool (V) to pull the reference line between the left and right sides of the document, then select the image> canvas size command, change the width to 1400 pixels in the dialog box, and click OK. In this way, we have a blank document with a width of

Common Oracle functions: nvl/nullif/case when/wm_concat/replace 1. nvl function nvl converts a null value to an actual value. The data type can be date, number, character, and data type must match: nvl (commision, 0) nvl (hiredate, '01-JAN-87 ') nvl (job_id, 'no manager') nvl (to_char (job_id), 'no manager') nvl can convert any data type, however, the returned value of the converted data type must be of the expr type of the first parameter nvl (expr1, expr2. example: date, number, varchar2 or ch
