db2_get_option

Retrieves an option value for a statement resource or a connection resource (PECL ibm_db2:1.6.0-1.6.2)
string db2_get_option ( resource resource, string option )

Retrieves the value of a specified option value for a statement resource or a connection resource.

Parameters

resource

A valid statement resource as returned from db2_prepare() or a valid connection resource as returned from db2_connect() or db2_pconnect().

option

A valid statement or connection options. The following new options are available as of ibm_db2 version 1.6.0. They provide useful tracking information that can be set during execution with db2_get_option().

Note:

Prior versions of ibm_db2 do not support these new options.

When the value in each option is being set, some servers might not handle the entire length provided and might truncate the value.

To ensure that the data specified in each option is converted correctly when transmitted to a host system, use only the characters A through Z, 0 through 9, and the underscore (_) or period (.).

userid: SQL_ATTR_INFO_USERID - A pointer to a null-terminated character string used to identify the client user ID sent to the host database server when using DB2 Connect.

Note:
DB2 for z/OS and OS/390 servers support up to a length of 16 characters. This user-id is not to be confused with the authentication user-id, it is for identification purposes only and is not used for any authorization.
acctstr: SQL_ATTR_INFO_ACCTSTR - A pointer to a null-terminated character string used to identify the client accounting string sent to the host database server when using DB2 Connect.

Note:
DB2 for z/OS and OS/390 servers support up to a length of 200 characters.
applname: SQL_ATTR_INFO_APPLNAME - A pointer to a null-terminated character string used to identify the client application name sent to the host database server when using DB2 Connect.

Note:
DB2 for z/OS and OS/390 servers support up to a length of 32 characters.
wrkstnname: SQL_ATTR_INFO_WRKSTNNAME - A pointer to a null-terminated character string used to identify the client workstation name sent to the host database server when using DB2 Connect.

Note:
DB2 for z/OS and OS/390 servers support up to a length of 18 characters.

The following table specifies which options are compatible with the available resource types:

Table 126. Resource-Parameter Matrix

Key	Value	Resource Type

userid	`SQL_ATTR_INFO_USERID`	X	X	-
acctstr	`SQL_ATTR_INFO_ACCTSTR`	X	X	-
applname	`SQL_ATTR_INFO_APPLNAME`	X	X	-
wrkstnname	`SQL_ATTR_INFO_WRKSTNNAME`	X	X	-

Return Values

Returns the current setting of the connection attribute provided on success or FALSE on failure.
