OpenEdge Data Management: DataServer for Microsoft SQL Server

Chapter 3: RDBMS Stored Procedure Details
As previously noted in Table 20, you can pass data types in the RUN
STORED-PROCEDURE statement using the PARAM phrase. Table 21 lists issues that occur
when you pass certain data types as parameters.
Table 21: Argument data types for stored procedures
OpenEdge MS SQL Server data source
DECIMAL
INTEGER
INT64
Note these stored procedure points:
The DataServer converts each of these data types in the
schema image to the equivalent default OpenEdge data type as
follows:
• DECIMAL=DECIMAL(default), or Float
• INTEGER=INTEGER
• INT64=BIGINT
However, you can use the Data Dictionary to update the data
type and format information in the field property sheet for the
parameter.
CHAR The data source represents this type as a VARCHAR parameter.
Its size cannot exceed the VARCHAR size limit for the associated
data source. If the VARCHAR parameter exceeds this limit, it
causes an error.
DATE If you pass a DATE data type as an input parameter and use it
in an equality test, the test might fail. In this case, use
DATEPART() or DATEDIFF() in the Transact-SQL of your native
stored procedure to isolate parts of the date structure for which
you might want to test.
DATETIME You can specify a DATETIME data type in a temp table used to
receive results from a stored procedure using the
LOAD-RESULT-INTO phrase.
MEMPTR You can specify a MEMPTR data type in a Param phrase as an
INPUT or an OUTPUT parameter to receive results from a
corresponding BLOB data type parameter to or from a RUN
STORED-PROCEDURE statement.
LONGCHAR You can specify a LONGCHAR data type in a Param phrase as an
INPUT or an OUTPUT parameter to receive results from a
corresponding CLOB data type parameter to or from a RUN
STORED-PROCEDURE statement.
• Input and output parameters are displayed as fields.
• Stored procedures called from within OpenEdge applications cannot return
Boolean values to LOGICAL data types.
• If you are running several stored procedures, run them serially and process all the
results from one stored procedure and close the procedure before you run a
second one. By default, the DataServer allows one active request for running a
stored procedure. It is not necessary to specify the PROC-HANDLE phrase when
procedures are run serially.
