Function Documentation

tibdgResultSetMetadata_GetColumnCount()

TIBDG_API tibint32_t tibdgResultSetMetadata_GetColumnCount	(	tibEx	e,
		tibdgResultSetMetadata	resultSetMetadata
	)

Get the number of columns to be expected in the result
when the statement associated with this metadata is executed.

Parameters

e	The exception object captures information about failures.
resultSetMetadata	The metadata returned when the associated statement was created.

Returns

On success, this call returns the number of columns in the result.
On failure, an exception is returned.

tibdgResultSetMetadata_GetColumnLabel()

TIBDG_API const char* tibdgResultSetMetadata_GetColumnLabel	(	tibEx	e,
		tibdgResultSetMetadata	resultSetMetadata,
		tibint32_t	columnNumber
	)

Get the column label associated with the specified column number. The column
label is the alias specified by the SQL AS clause. If an AS clause has not
been specified, the value returned will be the same as the value returned
by the tibdgResultSetMetadata_GetColumnName method.

Parameters

e	The exception object captures information about failures.
resultSetMetadata	The metadata returned when the associated statement was created.
columnNumber	Specifies the column number. Column numbers start with 1.

Returns

On success, this call returns the label of the column. If the AS clause was not
specified, the column name is returned. If the AS clause was not specified and
the column doesn't have a name, a TIB_NOT_FOUND exception is returned.
On failure, an exception is returned.

tibdgResultSetMetadata_GetColumnName()

TIBDG_API const char* tibdgResultSetMetadata_GetColumnName	(	tibEx	e,
		tibdgResultSetMetadata	resultSetMetadata,
		tibint32_t	columnNumber
	)

Get the column name associated with the specified column number. The column name
is the original column name defined in the datagrid. If a column does not have a name,
NULL is returned.

Parameters

e	The exception object captures information about failures.
resultSetMetadata	The metadata returned when the associated statement was created.
columnNumber	Specifies the column number. Column numbers start with 1.

Returns

On success, this call returns the name of the column. If the column doesn't have
a name, NULL is returned.
On failure, an exception is returned.

tibdgResultSetMetadata_GetColumnTableName()

TIBDG_API const char* tibdgResultSetMetadata_GetColumnTableName	(	tibEx	e,
		tibdgResultSetMetadata	resultSetMetadata,
		tibint32_t	columnNumber
	)

Get the name of the table associated with the specified column number.

Parameters

e	The exception object captures information about failures.
resultSetMetadata	The metadata returned when the associated statement was created.
columnNumber	Specifies the column number. Column numbers start with 1.

Returns

On success, this call returns the table name of the specified column.
On failure, an exception is returned.

tibdgResultSetMetadata_GetColumnType()

TIBDG_API tibdgColumnType tibdgResultSetMetadata_GetColumnType	(	tibEx	e,
		tibdgResultSetMetadata	resultSetMetadata,
		tibint32_t	columnNumber
	)

Get the type of the column associated with the specified column number.

Parameters

e	The exception object captures information about failures.
resultSetMetadata	The metadata returned when the associated statement was created.
columnNumber	Specifies the column number. Column numbers start with 1.

Returns

On success, this call returns the type of the specified column.
On failure, an exception is returned.

tibdgResultSetMetadata_IsColumnNullable()

TIBDG_API tibbool_t tibdgResultSetMetadata_IsColumnNullable	(	tibEx	e,
		tibdgResultSetMetadata	resultSetMetadata,
		tibint32_t	columnNumber
	)

Returns whether or not the specified column number is nullable.

Parameters

e	The exception object captures information about failures.
resultSetMetadata	The metadata returned when the associated statement was created.
columnNumber	Specifies the column number. Column numbers start with 1.

Returns

On success, this call returns tibtrue is the specified column is nullable.
Otherwise tibfalse is returned.
On failure, an exception is returned.
