Class name
Description
oa_ds_info
Defines the name, number, value, and remarks field of a customized driver info property.
oa_types_info
Defines the information describing a data type supported by the data source.
ResultBuffer
Stores the bulk fetch data temporarily.
scalar_functions
Registers user-defined scalar functions.
schemaobj_column
Defines column objects and is used to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_COLUMN.
schemaobj_fkeys
Defines foreign key column objects and is used to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_FKEY.
schemaobj_pkeys
Defines primary key column objects and is used to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_PKEY.
schemaobj_proc
Defines stored procedure objects and is used to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_PROC.
schemaobj_proccolumns
Defines stored procedure column objects and is used to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_PROCCOLUMNS.
schemaobj_stat
Defines index objects and is used to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_STAT.
schemaobj_table
Defines table objects and is used to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_TABLE.
xo_int
Allows the IP to return an integer value.
xo_long
Allows the IP to return an integer value.
