1  –  SQL statement

    Specifies a single executable SQL statement.

    Executable SQL statements undergo processing during module
    compile time but do not execute until the program runs. SQL
    executes the simple statement when the procedure in which it
    is embedded is called by a host language module. (Nonexecutable
    SQL statements are those that SQL processes completely when it
    compiles an SQL module but are not executed at run time.) See the
    Oracle Rdb SQL Reference Manual for information about which SQL
    statements are executable.

    The SQL statement must use names specified in the procedure's
    formal parameters wherever it refers to parameters.
