Focus Keyword: EXEC SQL vs EXEC Command in Pro*C

EXEC SQL Command:

The EXEC SQL command is specifically used for embedding SQL statements within Pro*C programs to interact with an Oracle database. It is primarily used for database operations such as query execution, data retrieval, and data manipulation.

EXEC Command:

The EXEC command, on the other hand, is a general-purpose command used in Pro*C programs for executing external programs or invoking system commands. It does not directly relate to SQL operations or database interactions.

Overall, the EXEC SQL command is essential for database-related tasks, while the EXEC command is more versatile for executing external commands within Pro*C programs.
