Addition 4

... CONNECTION {con|(con_syntax)}

Note

This addition is for internal use only.

It cannot be used in application programs

Effect

The Open SQL command is not executed on the standard database but on the specified secondary database connection . The database connection can be specified statically with con or dynamically as the content of con_syntax, where the field con_syntax must belong to the type c or string. The database connection must be specified with a name that is in column CON_NAME in table DBCON.

The addition CONNECTION must be specified immediately after the name of the database table or after the addition CLIENT SPECIFIED.

this is what I saw but don't get it what is that means

on application programs and internal program.

what is difference between them?

regards.

IIf the DB available internally then the connection keyword is possible to use different DB...not for the extenal servers...i.e. if the DB server resides outside of SAP.

connection keyword is not available to external server's DB.

is this what you mean?

I guess 'connection' is especially for external DB connection.

did I misunderstanding your answer again?

my question was what is difference application program and internal program.

note says connection keyword can not use application program.

what is application program exactly? what is definition?

abap program,abap function , bsp page abap code

which one can use do and can not do?

I thought 'application program' means all abap program.

but need to know what is application program and what is else to understand this note.

Internal use: means that....

You can write the select statement with "connection" keyword within abap (abapscript) only.

Application programs: here means that....

When you are writing a javascript coding , you can't use the same keyword.

Becuase ABAP native sql will recognize the keyword connection, but other will not recongnize....

I hope the help means the above answer...I'm sorry if it is wrong...
