Hi,
EXEC SQl statement does Native SQL .Normally we use OPEN sql statement.
This is not database specific.So datbase convetor converts into database specific sql statements for our sql statements.This is slow fetching compared to Native sql.
Open SQL allows you to access database tables declared in the ABAP Dictionary regardless of the database platform that you R/3 System is using. Native SQL allows you to use database-specific SQL statements in an ABAP program. This means that you can use database tables that are not administered by the ABAP Dictionary, and therefore integrate data that is not part of the R/3 System.
As a rule, an ABAP program containing database-specific SQL statements will not run under different database systems. If your program will be used on more than one database platform, only use Open SQL statements.
Native SQL Statements in ABAP Programs
To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:
REPORT demo_native_sql.
DATA: BEGIN OF wa,
connid TYPE spfli-connid,
cityfrom TYPE spfli-cityfrom,
cityto TYPE spfli-cityto,
END OF wa.
DATA c1 TYPE spfli-carrid VALUE 'LH'.
EXEC SQL PERFORMING loop_output.
SELECT connid, cityfrom, cityto
INTO :wa
FROM spfli
WHERE carrid = :c1
ENDEXEC.
FORM loop_output.
WRITE: / wa-connid, wa-cityfrom, wa-cityto.
ENDFORM.
