Function Documentation

TIBDG_API void tibdgSession_Commit	(	tibEx	e,
		tibdgSession	session
	)

Commit the current transaction on this session and begin a new transaction.

Committing a transaction causes the data grid to make permanent all table operations performed since the start of the current transaction.

Parameters

e	The exception object captures information about failures.
session	The session on which to commit the transaction.

Returns: void

TIBDG_API tibdgStatement tibdgSession_CreateStatement	(	tibEx	e,
		tibdgSession	session,
		const char *	sqlString,
		tibProperties	props
	)

Create a SQL statement object.

Parameters

e	The exception object captures information about failures.
session	The session from which to create to the statement object.
sqlString	The sql string used to create the statement.
props	Optional. `NULL` to omit. TIBDG_STATEMENT_PROPERTY_LONG_PREFETCH TIBDG_STATEMENT_PROPERTY_STRING_CONSISTENCY

Returns: On success, this call returns a new statement object.
On failure, this call returns NULL.

TIBDG_API tibdgBatchResult tibdgSession_DeleteRows	(	tibEx	e,
		tibdgSession	session,
		tibdgRow *	rows,
		tibint32_t	numRows,
		tibProperties	properties
	)

DELETE a batch of rows from the datagrid.

Note: the rows may be on different tables. Not valid for transacted sessions

Parameters

e	The exception object captures information about failures.
session	The session from which to DELETE the rows
rows	The array of rows to DELETE
numRows	The length of the rows array
properties	Optional. `NULL` to omit.

Returns: On success, this call returns a tibdgBatchResult
On failure, this call returns NULL.

TIBDG_API void tibdgSession_Destroy	(	tibEx	e,
		tibdgSession	session
	)

Destroy a session.

Release all the resources associated with this session.

If a transaction was started on this session, this call automatically rolls back the transaction.

Parameters

e	The exception object captures information about failures.
session	The session to be destroyed.

Returns: void

TIBDG_API tibint64_t tibdgSession_ExecuteUpdate	(	tibEx	e,
		tibdgSession	session,
		const char *	sqlString,
		tibProperties	props
	)

Execute a SQL Update.

A SQL update can be Create Table, Create Index, Drop Table, or Drop Index

Parameters

e	The exception object captures information about failures.
session	The session from which to execute the SQL Update
sqlString	The sql string representing the update to execute
props	Optional. `NULL` to omit.

Returns: On success, this call returns the number of rows modified by the update.
On failure, this call returns 0.

TIBDG_API tibdgConnection tibdgSession_GetConnection	(	tibEx	e,
		tibdgSession	session
	)

Get the connection object was used to create the session.

Parameters

e	The exception object captures information about failures.
session	The session from which to get the connection.

Returns: a connection object

TIBDG_API tibdgBatchResult tibdgSession_GetRows	(	tibEx	e,
		tibdgSession	session,
		tibdgRow *	rows,
		tibint32_t	numRows,
		tibProperties	properties
	)

GET a batch of rows from the datagrid.

Note: the rows may be on different tables. Not valid for transacted sessions

Parameters

e	The exception object captures information about failures.
session	The session from which to GET the rows
rows	The array of rows to GET
numRows	The length of the rows array
properties	Optional. `NULL` to omit.

Returns: On success, this call returns a tibdgBatchResult
On failure, this call returns NULL.

TIBDG_API tibdgTable tibdgSession_OpenTable	(	tibEx	e,
		tibdgSession	session,
		const char *	name,
		tibProperties	props
	)

Open a table in the data grid.

A table object contains rows and columns.

Parameters

e	The exception object captures information about failures.
session	The session on which to create this table.
name	The name of the table to be opened. This table must already be defined in the data grid.
props	Optional. `NULL` to omit.

Returns: On success, this call returns a new table object.
On failure, this call returns NULL.

TIBDG_API tibdgBatchResult tibdgSession_PutRows	(	tibEx	e,
		tibdgSession	session,
		tibdgRow *	rows,
		tibint32_t	numRows,
		tibProperties	properties
	)

PUT a batch of rows into the datagrid.

e	The exception object captures information about failures.
session	The session from which to PUT the rows
rows	The array of rows to PUT
numRows	The length of the rows array
properties	Optional. `NULL` to omit.

Returns: On success, this call returns a tibdgBatchResult
On failure, this call returns NULL.

TIBDG_API void tibdgSession_Rollback	(	tibEx	e,
		tibdgSession	session
	)

Rollback a transaction on this session.

Rolling back a transaction causes the data grid to discard all table operations performed since the start of the transaction.

Parameters

e	The exception object captures information about failures.
session	The session on which to rollback the transaction.
