DB2 Defining table fields

>[Error] Script line: 1-1---------------------------------------

"STATUS" is not valid in the context where it is used. sqlcode=-206, sqlstate=42703, driver=3.53.71

More exceptions ... An error occurred during implicit system action type "2". Information returned for the error includes SQLCODE " -206", SQLSTATE "42703" and Message Tokens "STATUS": sqlcode=-727, sqlstate=56098, driver=3.53.71

This error is always reported when executing the SQL text because:

In DB2, all names can contain characters by default: A-Z (uppercase) 0 to 9 @, #, $, and _ (underscore) names cannot begin with numbers and underscores.

A table of database objects whose names follow the above rules, so even if you use the command to create a table with lowercase, DB2 will still convert it to uppercase.

However, it is important to note that not the DB client software will be automatically converted, I am using the IBM Data Studio4 or Aqua Data studio and other clients, I found that statistics studio provided by the graphical interface created, not automatically converted to uppercase,

For example, when you create a table using studio, you define the field as a lowercase status, and then use normal SQL statement operations, such as:

SELECT * from Large_receipt where status= ' E ' will error

WORKAROUND: Use uppercase letters when defining
