Object Hierarchy

    GBoxed
    ├── GdaServerOperationCreateTableArg
    ╰── GdaServerOperationCreateTableArgFKeyRefField
    GObject
    ╰── GdaServerOperation

Description

This object is basically just a data store: it can store named values, the values being organized hierarchically by their name which are similar to a Unix file path. For example a value can be read from its path using the gda_server_operation_get_value_at() method, or set using the gda_server_operation_set_value_at() method.

Each GdaServerOperation contains some structure which is usually defined by a database provider to implement a specific operation. The structure is composed of the following building blocks:

  • Named values (internally represented as a GdaHolder object)

  • Named values in a vector (internally represented as a GdaSet object)

  • Values in an array (internally represented as a GdaDataModel object)

  • Sequences of one or more of the previous blocks. A sequence can contain any number of instances of the template block (there may be lower and upper boundaries to the number of instances)

Important note: GdaServerOperation objects are usually not created manually using gda_server_operation_new(), but using a GdaServerProvider object with gda_server_provider_create_operation(). See the global introduction about DDL for more information. Alternatively one can use the Convenience functions which internally manipulate GdaServerOperation objects.

gda_server_operation_set_value_at ()

                                   ...);

Set the value for the node at the path formed using path_format and the ... ellipse (the rules are the same as for g_strdup_printf()).

Note that trying to set a value for a path which is not used by the current provider, such as "/TABLE_OPTIONS_P/TABLE_ENGINE" for a PostgreSQL connection (this option is only supported for MySQL), will not generate any error; this allows one to give values to a superset of the parameters and thus use the same code for several providers.

Here are the possible formats of path_format :

  • If the path corresponds to a GdaHolder, then the parameter is set to "<parameter>value</parameter>"

  • If the path corresponds to a sequence item like for example "/SEQUENCE_NAME/5/NAME" for the "NAME" value of the 6th item of the "SEQUENCE_NAME" sequence then:

    • if the sequence already has 6 or more items, then the value is just set to the corresponding value in the 6th item of the sequence

    • if the sequence has less then 6 items, then items are added up to the 6th one before setting the value to the corresponding in the 6th item of the sequence

  • If the path corresponds to a GdaDataModel, like for example "/ARRAY/@COLUMN/5" for the value at the 6th row of the "COLUMN" column of the "ARRAY" data model, then:

    • if the data model already contains 6 or more rows, then the value is just set

    • if the data model has less than 6 rows, then rows are added up to the 6th one before setting the value

Parameters

a GdaServerOperation object

 

value

a string.

[nullable]

path_format
