A lookup table, which contains, as keys, the case values and, as values, the part under the case statement. (In some languages, only actual data types are allowed as values in the lookup table. In other languages, it is also possible to assign functions as lookup table values, gaining the same flexibility as a real switch statement.
All Cerner Millennium health information technology software uses CCL/Discern Explorer to select from, insert into, update into and delete from a Cerner Millennium database and allows a programmer to fetch data from an Oracle database and display it as the user wants to see. With features like Record Structure and subroutines it allows a user ...
The DUAL table is a special one-row, one-column table present by default in Oracle and other database installations. In Oracle, the table has a single VARCHAR2(1) column called DUMMY that has a value of 'X'. It is suitable for use in selecting a pseudo column such as SYSDATE or USER.
In such case it is always possible to use a function call, but this can be cumbersome and inelegant. For example, to pass conditionally different values as an argument for a constructor of a field or a base class, it is impossible to use a plain if-else statement; in this case we can use a conditional assignment expression, or a function call ...
A pseudo-oracle, as defined by Weyuker, [12] is a separately written program which can take the same input as the program or SUT so that their outputs may be compared to understand if there might be a problem to investigate. A partial oracle [6]: 515 is a hybrid between specified test oracle and derived test oracle. It specifies important (but ...
C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions. In any case, a possible way to implement exception handling in standard C is to use setjmp/longjmp functions:
In Fortran, a computed GOTO jumps to one of several labels in a list, based on the value of an expression. An example is goto (20,30,40) i. [44] The equivalent construct in C is the switch statement, and in newer Fortran a SELECT CASE construct is the recommended syntactical alternative. [45]
To work with cursors you must use the following SQL statements This section introduces the ways the SQL:2003 standard defines how to use cursors in applications in embedded SQL. Not all application bindings for relational database systems adhere to that standard, and some (such as CLI or JDBC ) use a different interface.
