GdaRepetitiveStatement

GdaRepetitiveStatement — Execute the same statement several times with different values

Stability Level

Stable, unless otherwise indicated

Types and Values

Description

The GdaRepetitiveStatement object allows one to specify a statement to be executed several times using different variables' values sets for each execution. Using the object has almost no interrest at all if the statement to be executed several times has no parameter.

Use the gda_connection_repetitive_statement_execute() method to execute the repetitive statement.

Functions

gda_repetitive_statement_new ()

GdaRepetitiveStatement *
gda_repetitive_statement_new (GdaStatement *stmt);

Creates a new GdaRepetitiveStatement object which, when executed, will execute stmt once for all the values set which will have been defined using gda_repetitive_statement_append_set(). Use gda_connection_repetitive_statement_execute() to actually execute it.

Parameters

stmt

a GdaStatement object

 

Returns

a new GdaRepetitiveStatement object

Since 4.2


gda_repetitive_statement_get_template_set ()

gboolean
gda_repetitive_statement_get_template_set
                               (GdaRepetitiveStatement *rstmt,
                                GdaSet **set,
                                GError **error);

Gets a new GdaSet object with the parameters used by the template statement in the rstmt object.

Use this object with gda_repetitive_statement_append_set().

Parameters

rstmt

a GdaRepetitiveStatement object

 

set

a place to store the returned template set

 

error

a place to store error, or NULL.

[allow-none]

Returns

TRUE on success, FALSE on error

Since 4.2


gda_repetitive_statement_get_all_sets ()

GSList *
gda_repetitive_statement_get_all_sets (GdaRepetitiveStatement *rstmt);

Get all the values sets which will have been added using gda_repetitive_statement_append_set().

Parameters

rstmt

a GdaRepetitiveStatement object

 

Returns

a new GSList of GdaSet objects (free with g_slist_free()).

Since 4.2


gda_repetitive_statement_append_set ()

gboolean
gda_repetitive_statement_append_set (GdaRepetitiveStatement *rstmt,
                                     GdaSet *values,
                                     gboolean make_copy);

Specifies that rstmt be executed one time with the values contained in values .

A new GdaSet to be used as the values argument can be obtained using gda_repetitive_statement_get_template_set().

Parameters

rstmt

a GdaRepetitiveStatement object

 

values

a GdaSet object with the values to be used

 

make_copy

TRUE if values is copied, and FALSE if values is only ref'ed

 

Returns

a new GdaRepetitiveStatement object

Since 4.2
