Methods / Constructors
Method / Constructor		Defined By
	new Gda.Statement (Object *properties) Create a new Gda.Statement Create a new Gda.Statement Parameters: Object properties*
	check_structure () : Boolean Checks that stmt's structure is correct. Checks that stmt's structure is correct. Returns: Boolean	Gda.Statement
	check_validity (Connection *cnc) : Boolean If cnc* is not NULL then checks that every object (table, field, function) used in stmt actually exists in cnc's database If cnc is NULL, then cleans anything related to cnc in stmt. If cnc is not NULL then checks that every object (table, field, function) used in stmt actually exists in cnc's database If cnc is NULL, then cleans anything related to cnc in stmt. See gda_sql_statement_check_validity() for more information. Parameters: Gda.Connection cnc a GdaConnection object, or NULL Returns: Boolean	Gda.Statement
	copy () : Gda.Statement Copy constructor Copy constructor Returns: Gda.Statement	Gda.Statement
	get_parameters (Object *out_values) : Boolean Get a new GdaSet* object which groups all the execution parameters which stmt needs. Get a new GdaSet object which groups all the execution parameters which stmt needs. This new object is returned though out_params. Note that if stmt does not need any parameter, then out_params is set to NULL. Parameters: Object out_values Gda.Set out_params Returns: Boolean	Gda.Statement
	get_statement_type () : Gda.SqlStatementType Get the type of statement held by stmt. Get the type of statement held by stmt. It returns GDA_SQL_STATEMENT_NONE if Returns: Gda.SqlStatementType the statement type	Gda.Statement
	is_useless () : Boolean Tells if stmt is composed only of spaces (that is it has no real SQL code), and is completely useless as such. Tells if stmt is composed only of spaces (that is it has no real SQL code), and is completely useless as such. Returns: Boolean	Gda.Statement
	normalize (Connection *cnc) : Boolean "Normalizes" some parts of stmt, see gda_sql_statement_normalize() for more information. "Normalizes" some parts of stmt, see gda_sql_statement_normalize() for more information. Parameters: Gda.Connection cnc* Required (not null) Returns: Boolean	Gda.Statement
	serialize () : String Creates a string representing the contents of stmt. Creates a string representing the contents of stmt. Returns: String	Gda.Statement
	to_sql_extended (Connection *cnc, Set params, StatementSqlFlag flags, Object out_values) : String Renders stmt* as an SQL statement, with some control on how it is rendered. Renders stmt as an SQL statement, with some control on how it is rendered. If cnc is not NULL, then the rendered SQL will better be suited to be used by cnc (in particular it may include some SQL tweaks and/or proprietary extensions specific to the database engine used by cnc): in this case the result is similar to calling gda_connection_statement_to_sql(). Parameters: Gda.Connection cnc Required (not null) Gda.Set params Required (not null) Gda.StatementSqlFlag flags Required (not null) Object out_values Array params_used Returns: String	Gda.Statement
	to_sql_real (SqlRenderingContext *context) : String Renders stmt* to its SQL representation, using context to specify how each part of stmt must be rendered. Renders stmt to its SQL representation, using context to specify how each part of stmt must be rendered. This function is mainly used by database provider's implementations which require to specialize some aspects of SQL rendering to be adapted to the database,'s own SQL dialect (for example SQLite rewrites the 'FALSE' and 'TRUE' literals as '0' and 'NOT 0'). Parameters: Gda.SqlRenderingContext context Required (not null) Returns: String	Gda.Statement

Events - usage syntax: this.signals.EVENTNAME.connect( Function )
Event		Defined By
	checked (Statement *self, Connection object, Boolean p0) : none Parameters: Gda.Statement self* Gda.Connection object Boolean p0 Returns: {none}	Gda.Statement
	reset (Statement *self) : none Parameters: Gda.Statement self* Returns: {none}	Gda.Statement

Gda Method	Gda.compute_dml_statements (Connection *cnc, Statement select_stmt, Boolean require_pk, Statement insert_stmt, Statement update_stmt, Statement delete_stmt*) : Boolean
Gda Method	Gda.compute_select_statement_from_update (Statement *update_stmt*) : Gda.SqlStatement
Gda Method	Gda.select_alter_select_for_empty (Statement *stmt*) : Gda.Statement
Gda.Batch Method	add_statement (Statement *stmt) : none Add stmt* to the list of statements managed by batch.
Gda.Batch Method	remove_statement (Statement *stmt) : none Removes stmt* from the list of statements managed by batch.
Gda.Connection Method	statement_to_sql (Statement *stmt, Set params, StatementSqlFlag flags, Object out_values) : String Renders stmt* as an SQL statement, adapted to the SQL dialect used by cnc
Gda.Connection Method	statement_prepare (Statement *stmt) : Boolean Ask the database accessed through the cnc* connection to prepare the usage of stmt.
Gda.Connection Method	statement_execute (Statement *stmt, Set params, StatementModelUsage model_usage, Object out_values) : GObject.Object Executes stmt*.
Gda.Connection Method	statement_execute_select (Statement *stmt, Set params*) : Gda.DataModel Executes a selection command on the given connection.
Gda.Connection Method	statement_execute_select_full (Statement *stmt, Set params, StatementModelUsage model_usage, Array col_types*) : Gda.DataModel value.
Gda.Connection Method	statement_execute_non_select (Statement *stmt, Set params, Object out_values*) : Number Executes a non-selection statement on the given connection.
Gda.Connection Method	async_statement_execute (Statement *stmt, Set params, StatementModelUsage model_usage, Array col_types, Boolean need_last_insert_row*) : Number This method is similar to gda_connection_statement_execute() but is asynchronous as it method returns immediately with a task ID.
Gda.Connection Method	add_prepared_statement (Statement *gda_stmt, PStmt prepared_stmt) : none Declares that prepared_stmt* is a prepared statement object associated to gda_stmt within the connection (meaning the connection increments the reference counter of prepared_stmt).
Gda.Connection Method	del_prepared_statement (Statement *gda_stmt*) : none gda_connection_add_prepared_statement() does.
