CALL DATABASE PROCEDURE
${ proxy $[CONNECTION con$|(con_syntax)$]
parameter_list $}
$| ${ (proxy_name) $[CONNECTION con$|(con_syntax)$] ${
parameter_list
$|parameter_table$} $}.
Addition:
... CONNECTION con$|(con_syntax)
Effect
This statement calls a database procedure written in SQLScript (SQLScript procedure) on an SAP HANA database.
- If the addition CONNECTION is not specified, the statement can only be executed in a system on the SAP HANA database.
- If the addition CONNECTION is specified, the statement can be executed in every system with a secondary connection to an SAP HANA database.
The SQLScript procedure is specified using a database procedure proxy defined for it. The proxy can be specified as follows:
- proxy
- Specified directly and statically as proxy.
- (proxy_name)
- Specified as the uppercase content of a parenthesized character-like data object proxy_name. The following can be specified for proxy_name:
- Literal or constants
- If the data object proxy_name is specified as a character literal or as a constant, it can be evaluated statically, and the specified proxy is recognized as the used object.
- Variable
- If the data object proxy_name is specified as a variable, it is specified only dynamically and the content is not evaluated statically.
- When the statement is executed, proxy_name is not evaluated until runtime in both cases.
The actual parameters for the input and output parameters of the procedure are either specified statically using parameter_list or dynamically using parameter_table.
Notes
- The names of the database procedure proxy and database procedure interface are freely definable. Usually, the database procedure interface has the name of the database procedure proxy with the prefix IF_, and any additional namespace prefix.
- The constant CALL_DATABASE_PROCEDURE of the class CL_ABAP_DBFEATURES can be used to query whether the current database supports database procedure proxies.
- ABAP Managed Database Procedures (AMDP) are a recommended alternative to the statement CALL DATABASE PROCEDURE if the standard AS ABAP database is an SAP HANA database. Any database procedures of the standard database can be called from AMDP, which makes the use of database procedure proxies superfluous as long as a secondary connection is not used to access another SAP HANA database.
- No database procedure proxies can be used for SQLScript procedures in SAP HANA XSA. Alternative methods such as AMDP or ADBC must be used instead.
- No database procedure proxies can be used on a
SAP HANA Cloud
database. The method CL_SHDB_HC=>IS_HANA_CLOUD can be used to check if the current database is a SAP HANA Cloud database.
Addition
... CONNECTION con$|(con_syntax)
Effect
The SQLScript procedure is not executed on the standard connection but on the specified secondary connection instead. The database connection can be specified statically with con or dynamically as the content of con_syntax, where the field con_syntax must be of the type c or string. The database connection must be specified with a name from the column CON_NAME in the table DBCON or that begins with the prefix R/3* and hence represents a service connection to the standard database.
Notes
- The specified database procedure proxy for the database procedure of the secondary connection must exist in the current system.
- Entries in the DDIC database table DBCON can only be created and modified using the DBA Cockpit tool.
- The use of CALL DATABASE PROCEDURE with the addition CONNECTION is recommended in
all scenarios in which existing database procedures are used in an SAP HANA database that is not the current standard AS ABAP database (side-by-side scenario).
Example
SQLScript Procedure
Take the following SQLScript procedure:
/********* Begin Procedure Script ************/
BEGIN
out_items = select items.pos,
items.first_name,
items.last_name,
items.posting_date as date,
items.currency,
items.amount
from zngd_items as items
inner join :in_sel as sel
on ( items.first_name = sel.first_name and
items.last_name = sel.last_name )
where posting_date = :in_date;
END;
/********* End Procedure Script ************/
The input parameters are:
Parameter | Database Type |
in_sel | Table data type |
in_date | Scalar |
The components of in_sel are:
Component | Database Type |
FIRST_NAME | NVARCHAR, length 20 |
LAST_NAME | NVARCHAR, length 20 |
The output parameters are:
Parameter | Database Type |
out_items | Table data type |
The components of out_items are:
Component | Database Type |
POS | INTEGER |
FIRST_NAME | NVARCHAR, length 20 |
LAST_NAME | NVARCHAR, length 20 |
DATE | INTEGER |
CURRENCY | NVARCHAR, length 4 |
AMOUNT | DECIMALS, length 11, scale 2 |
Database Procedure Proxy
The following mapping is defined in the associated database procedure proxy ..._PROXY:
Procedure Parameter | ABAP Name | ABAP Data Type |
IN_SEL | IN_SEL | Internal table |
IN_SEL, FIRST_NAME | IN_SEL, FIRST_NAME | c, length 20 |
IN_SEL, LAST_NAME | IN_SEL, LAST_NAME | c, length 20 |
IN_DATE | IN_DATE | d |
OUT_ITEMS, POS | OUT_ITEMS, POS | i |
OUT_ITEMS, FIRST_NAME | OUT_ITEMS, FIRST_NAME | c, length 20 |
OUT_ITEMS, LAST_NAME | OUT_ITEMS, LAST_NAME | c, length 20 |
OUT_ITEMS, DATA | OUT_ITEMS, POSTING_DATE | d |
OUT_ITEMS, CURRENCY | OUT_ITEMS, CURRENCY | c, length 4 |
OUT_ITEMS, AMOUNT | OUT_ITEMS, AMOUNT | p, length 6, 2 decimal places |
The name and type changes in the date fields should be noted.
Database Procedure Interface
The database procedure interface IF_..._PROXY is generated with the following type declarations:
INTERFACE if_..._proxy PUBLIC.
TYPES: BEGIN OF in_sel,
first_name TYPE c LENGTH 20,
last_name TYPE c LENGTH 20,
END OF in_sel.
TYPES: in_date TYPE d.
TYPES: BEGIN OF out_items,
pos TYPE i,
first_name TYPE c LENGTH 20,
last_name TYPE c LENGTH 20,
posting_date TYPE d,
currency TYPE c LENGTH 4,
amount TYPE p LENGTH 6 DECIMALS 2,
END OF out_items.
ENDINTERFACE.
Database Procedure Call
The following ABAP program section calls the SQLScript procedure using the name of the database procedure proxy, whereby actual parameters typed using the database procedure interface are used.
DATA:
in_date TYPE if_..._proxy=>in_date,
in_sel TYPE STANDARD TABLE
OF if_..._proxy=>in_sel
WITH EMPTY KEY,
out_items TYPE STANDARD TABLE
OF if_..._proxy=>out_items
WITH EMPTY KEY.
in_date = '20120329'.
in_sel = VALUE #( ( first_name = 'Dolores' last_name = 'Oh' )
( first_name = 'Benjacomin' last_name = 'Bozart' )
( first_name = 'Johanna' last_name = 'Gnade' ) ).
IF cl_abap_dbfeatures=>use_features(
EXPORTING
requested_features =
VALUE #( ( cl_abap_dbfeatures=>call_database_procedure ) ) )
AND NOT cl_shdb_hc=>is_hana_cloud( ).
CALL DATABASE PROCEDURE ..._proxy
EXPORTING in_date = in_date
in_sel = in_sel
IMPORTING out_items = out_items.
ENDIF.
The example Database Procedure Call uses a database procedure proxy created in the program to call a SQLScript procedure created using
ADBC.
