ODBC Connection Properties

When connecting to an SAP HANA database using ODBC, there are several connection properties that you can specify.

The following table lists the HANA client-specific ODBC connection properties:

Property	Value	Default	Description
ABAPVARCHARMODE	boolean	FALSE	In ABAP VARCHAR mode, a single space and an empty string are considered the same.
AUTOCOMMIT	boolean	FALSE	When in autocommit mode, every statement is automatically committed. Otherwise, commits and/or rollbacks must be done manually.
BINTEXT_IS_NCLOB	boolean	TRUE	Determines which SQL type is used to describe BINTEXT columns. TRUE if the type is returned as SQL_WLONGVARCHAR(-10), and FALSE if the type is returned as SQL_LONGVARBINARY(-4). Use FALSE to maintain compatibility with HANA versions earlier than 2.0.
CACHEDVIEWTS	boolean	TRUE	Allows the sending of last refresh TS/max refresh time for cached views (only available in SQLDBC).
CHAR_AS_UTF8	boolean	FALSE	Returns CHAR data in UTF-8 format.
CHOPBLANKS	boolean	FALSE	Chop off trailing blanks of character output.
CHOPBLANKSINPUT	boolean	FALSE	Chop off trailing blanks of character input.
CONNECTTIMEOUT	timeout in milliseconds	0 (disabled)	Aborts connection attempts after the specified timeout. Setting this option to 0 disables the timeout.
CURRENTSCHEMA	<schema>	CURRENTUSER	Sets the current schema, which is used for identifiers without schema.
DATABASENAME	<name>	The name of the database to connect to in multi-tenant database container systems.
DISTRIBUTION	OFF, CONNECTION, STATEMENT, ALL	STATEMENT	Choose the distribution mode. Specifying STATEMENT does not include CONNECTION distribution.
EMPTYTIMESTAMPISNULL	boolean	TRUE	When enabled, DAYDATE, SECONDTIME, SECONDDATE, and LONGDATE values inserted as empty strings are returned as NULLs. When disabled, these values are returned as out-of-band values.
ISOLATIONLEVEL	TRANSACTION_READ_COMMITTED, TRANSACTION_REPEATABLE_READ, TRANSACTION_SERIALIZABLE	TRANSACTION_READ_COMMITTED	Sets the isolation level for the connection.
LOCALE	ISO locale code	client locale	The client locale.
PACKETSIZE	<number>	1 MB	Sets the maximum size of a request packet sent from the client to the server in bytes. The minimum is 1 MB.
PWD	<password>	NA	The user password. Optional, depending on the used authentication method.
RECONNECT	boolean	FALSE	When enabled, the system automatically reconnects to the database instance after a command timeout or when the connection was broken and reconnecting restores the old state (for example, if no transaction was open).
SCROLLABLERESULT	boolean	FALSE	Enables or disables scrollable results sets.
SERVERNODE	<host>:<port>[, <host>:<port> ]	NA	Should contain all master candidates. See Administration Guide for details.
SHOW_CATALOGS	boolean	FALSE	Enables Microsoft-specific application support. This is needed to connect to HANA from Excel and Access.
SPATIALTYPES	boolean	2	Determines the ODBC SQL type returned for the ST_POINT and ST_GEOMETRY columns. Possible values are: TRUE Returns SQL_TYPE_ST_POINT and SQL_TYPE_ST_GEOMETRY FALSE Returns SQL_VARBINARY Unspecified (2) Returns SQL_TYPE_DST_GEOMETRY
SPLITBATCHCOMMANDS	boolean	TRUE	Allow split and parallel execution of batch commands on partitioned tables.
UID	<user>	NA	The user name. Optional, depending on used authentication method.
